Patient Information

Veterans have a higher prevalence of type 2 diabetes mellitus (T2DM) when compared with their civilian counterparts with an overall prevalence rate of 25%.¹ This higher prevalence is similar to other major chronic health conditions, including heart disease and arthritis, with additional costs for disease self-management.² Psychological and behavioral change strategies are a principal means of limiting the severity and even restoring function once T2DM is diagnosed.³ More broadly, there is mounting evidence that addressing distress and behavior change are important across many conditions, particularly T2DM.⁴ Therefore, the US Department of Veterans Affairs (VA) has established patient education and multidisciplinary interventions to optimize engagement in T2DM self-management and health behavior change.⁵

Traditional T2DM education programs aim to meet the American Diabetes Association (ADA) standards of medical care and include a T2DM educator and other allied health professionals. ADA Standard 1.2 emphasizes “productive interactions between a prepared, proactive care team and an informed, activated patient.”⁶ Thus, to attain ADA accreditation, educational programs require instructors to teach about T2DM while engaging patients to help them set and achieve recommended changes. The requirements emphasize setting specific goals, (ie, eating wisely, being physically active, monitoring blood sugars or taking medications). The care team also helps to identify barriers, and at a required follow-up class, patients evaluate how well they met goals and make modifications if needed. The impact of traditional patient education programs to improve glycemic levels is well established.⁷ Importantly, veterans with comorbid mental health conditions may not experience the same beneficial outcomes if or when they participate in traditional diabetes or self-management programs.^8,9 Veterans with T2DM may be particularly vulnerable to chronic stress and effects of comorbid mental health diagnoses.¹⁰ Furthermore, when individuals experience T2DM-related distress, associations with poor health outcomes, including elevated hemoglobin A_1c (HbA_1c), are observed independent of depression.¹¹

Health psychology services integrate into medical settings and strive to reach veterans who may not engage in traditional mental health clinical offerings.¹² These collaborative interventions focus less on diagnostic or screening procedures and more on a patient’s understanding of illness and ability and willingness to carry out treatment regimens. Given the significant roles of distress and co-occurring conditions, health psychology services further aim to provide psychoeducation about stress management in order to explore and enhance motivation for making a wide range of health behavior changes.

The purpose of this study was to evaluate baseline and follow-up HbA_1c, weight, and psychosocial measures, namely, health-related self-efficacy and T2DM-related distress among a small sample that engaged in integrated health psychology services. The focus of this evidence-based psychotherapy service was to improve T2DM self-care and physical health. The participants were offered cognitive and behavioral strategies for setting and meeting personalized T2DM self-management goals. Importantly, motivational interviewing was used throughout to adapt to the participants’ preferences and needs as well as to maintain engagement.

Methods

Primary care providers referred veterans with T2DM to the Health Psychology service at VA Ann Arbor Healthcare System (VAAAHS). A T2DM diagnosis was verified through electronic health record review. Most common referrals included addressing coping with chronic illness and improving glycemic levels. Veterans were invited to participate in a program evaluation project to monitor health-related changes. All participants provided written informed consent and did not receive incentive or payment for participating. The VAAAHS Institutional Review Board reviewed and approved this study.

Intervention

Veterans met individually with a health psychologist or health psychology trainee to create personalized health and behavioral goals for improving T2DM self-management, overall health, and psychological well-being. This intervention included motivational interviewing, SMART (specific, measurable, action-oriented, realistic, timely) goal setting, behavioral activation, acceptance of T2DM-related physical changes, problem-solving therapy, challenging maladaptive disease-related cognitions, and incorporating values to help find motivation for change. Interventionists took a flexible approach and met in-person in primary or specialty care clinics, over the phone, and through telehealth 1 to 4 times a month, meeting participant preferences, with sessions typically ranging from 45 to 60 minutes. The goal of the study was to disseminate and implement evidence-based behavioral change strategies into a multidisciplinary team format without excluding veterans who would benefit from receiving active treatment. Due to this translational approach, a control group was not included for comparison.

Data Collection

Participants completed study measures at the beginning and end of the T2DM-focused intervention sessions. Demographic variables collected included age, sex, race/ethnicity, highest educational attainment, and whether a veteran was prescribed insulin, service connected for T2DM, concurrent enrollment in other educational programs, and time since T2DM diagnosis. Measures were selected based on their relevance to T2DM psychosocial care and diabetes health outcomes.¹³

Body mass index, low-density lipoprotein cholesterol, blood pressure (BP), HbA_1c within 3 months of the pre- and postmeasures were collected by reviewing medical records. T2DM complications were collected by self-report, and comorbid physical and mental health conditions were collected by review of the most recent primary care note. The Diabetes Empowerment Scale-Short Form (DES-SF) is a well-validated measure that was used to measure T2DM-related psychosocial self-efficacy.¹⁴ Scores ranged from 8 to 40 with higher scores indicating higher diabetes T2DM empowerment. The Patient Health Questionnaire 9-item (PHQ-9) was used to assess the frequency of somatic (fatigue, appetite, psychomotor) and cognitive symptoms (anhedonia, low mood) of depression over the past 2 weeks.¹⁵ The Generalized Anxiety Disorder 7-item (GAD-7) was used to assess the frequency of common anxiety symptoms, including feelings of worry, difficulty controlling worry, and trouble relaxing.¹⁶ Veterans were also asked to rate their general health on a 5-point Likert scale. Self-rated health is a well-established indicator of disability and risk of future T2DM complications in older adults.^17,18 The Diabetes Distress Scale (DDS) was used to measure emotional burden, physician-related distress, regimen-related distress, and T2DM-related interpersonal distress.¹⁹ Scores > 2.0 suggest clinical significant diabetes distress.²⁰ Medication questionnaires were adapted from Wilson and colleagues, 2013.²¹

Statistical Analyses

Descriptive statistics, including mean and standard deviation (SD) or frequency distributions, as appropriate, were used to characterize the sample. For pre- and postintervention within-group comparisons, a paired samples Student t test analysis was used to evaluate baseline and follow-up measures for statistically significant differences between continuous variables; scores also were evaluated for clinically meaningful change.

Results

This sample (N = 13) of older adults was predominately male, white, with HbA_1c > 7.0, and prescribed insulin (Table). On average, participants were at higher risk for future complications due to high BP, hyperlipidemia, and BMI > 30.0. Regarding participation, veterans were seen for an average of 7.8 sessions (range, 4-13) with 46% service connected for T2DM. Of note, 4 veterans received other T2DM-specific self-management support within the same year of their participation with health psychology, such as attending a T2DM education class or T2DM shared medical appointment.²² Reliability in the current sample for the DES-SF was high (Cronbach α = 0.90), PHQ-9 was good (Cronbach α = 0.81), and GAD-7 was very good (Cronbach α = 0.86).

Among the 13 older adults, the most common T2DM-related complications included peripheral neuropathy (n = 7), heart pain or heart attack (n = 5), and retinopathy (n = 4). Recent primary care notes showed a mean (SD) 7 (2.2) comorbid chronic medical conditions with a high prevalence of cardiometabolic illnesses including hypertension, hyperlipidemia, obstructive sleep apnea, and a diagnosis of chronic pain. Eleven veterans were diagnosed with a mental health condition, including bipolar disorder, depression, anxiety, trauma-related disorder, and sleep disorders. Veterans reported high T2DM emotional distress (mean [SD] 3.1 [1.2]), moderate regimen-related distress (mean [SD] 2.9 [1.1]), and moderate total T2DM distress (mean [SD] 2.4 [0.7]). Physician distress (mean [SD] 1.3 [0.55]) and interpersonal T2DM distress (mean [SD] 1.6 [0.9]) subscales indicated little to no distress. The sample reported mild symptoms of depression (PHQ-9 mean [SD] 8.8 [4.6]); mild symptoms of anxiety (GAD-7 mean, 7.1; SD, 4.4), and Diabetes Empowerment (mean, 31.2; SD, 6.0). Participants described missing an average of 2.4 days within the past 30 days of their T2DM oral medications.

Twelve veterans (92.7%) completed the Follow-up questionnaires. The Figure illustrates statistically significant changes in patient-reported outcomes between baseline and follow-up. Clinically meaningful reductions were shown in total T2DM distress (t₁₁ = 5.03, P < .01), T2DM emotional burden (t₁₁ = 4.83, P = .01), and T2DM regimen-related distress (t₁₁ = 5.14, P < .01). There was a significant increase in T2DM self-efficacy (t₁₁ = 0.32, P = .008) as well. A statistically significant reduction was seen in depressive symptoms (t₁₁ = 2.22, P = .048). While HbA_1c fell by .56 percentage points (standard error of the mean [SEM], 31; P = .10), this change was not statistically significant. Follow-up analyses also showed a clinically, though not statistically, significant reduction in weight loss by 6.9 lb. (SEM, 3.8; P = .20), and reductions of generalized anxiety by 1.2 points (SEM, 1.4; P = .42). Pre- and postanalyses did not show differences among self-rated health, physician-related burden, interpersonal-related burden, and indicators of medication taking behavior.

Discussion

This observational study evaluated change among patient-reported T2DM-specific and general distress measures and health outcomes among a small sample of veterans at VAAAHS medical center that engaged in an episode of individual care with health psychology. Statistically significant decreases were observed in T2DM-related distress. Noteworthy, these decreases were observed for the emotional burden and regimen subscales, and each of these was clinically meaningful, falling below a score of 2.0 on the T2DM-specific scale. This is important given that T2DM distress may interfere with the ability to understand and find motivation for engaging in health behavior change. Incorporating stress management interventions into interdisciplinary health programs has been demonstrated to improve not only levels of distress, but also other health outcomes, such as health related quality of life and cardiac events in heart disease.²³ Thus, behavioral health interventions that incorporate cognitive-behavioral strategies to enhance distress-specific coping may prove important to include among individuals with T2DM.

Reductions in T2DM-related distress also converged with increases observed in the T2DM empowerment scale. These significant improvements in perceived ability suggest increased self-efficacy and willingness to follow a daily T2DM regimen. This finding aligns with the social support literature that demonstrates how instrumental and other aspects of autonomous social support mediate improvements in health-related outcomes and reduced T2DM distress.^24,25 Health psychology interventions strive to both provide social support as well as enhance participants’ perceptions and use of existing support as a cognitive-behavioral strategy. Adding in assessments of social support could shed light on such mediating factors.

The ADA standards of care encourage heath care providers to engage patients in conversations in order to better understand the barriers of T2DM self-care.¹³ How to best support patients within a primary care multidisciplinary team remains unclear.²⁶ T2DM distress and negative reactions to T2DM, including symptoms of anxiety and depression, are common and may require specific referral to a mental health provider if repeated attempts at T2DM education do not improve self-management and illness biomarkers.²⁷ Thus, integrating these providers and services within the medical setting aims to reach more veterans and potentially meet these standards of care. With our health psychology integrated services, clinically significant decreases in anxiety and statistically significant decreases in depressive symptoms were observed that approached “mild to no” symptoms. Although this was not measured formally, the veterans were not engaging in mental health specialty care historically or during the year of the health psychology intervention. This suggests that health psychology services helped bridge the gap and address these psychosocial needs within the small sample.

For clinical measures, modest decreases were observed for HbA_1c and weight. The authors recognize that these changes may not be optimal in terms of health status. A review of the specific patient-centered goals may illuminate this finding. For example, 1 participant had a goal to consume fewer sugary beverages and achieved this behavior change. Yet this change alone may not equate to actual weight loss or a lower HbA_1c. Furthermore, in the context of T2DM-related distress, maintaining current weight and/or blood sugar levels may be a more realistic goal. An evaluation of the specific patient-oriented action goals and observed progress may be important outcomes to include in larger studies. Moreover, while not significant, the average HbA_1c decrease of about 1% is comparable with traditional T2DM education and should be considered in light of the sample’s significant mental health comorbidities. While landmark intensive glucose control trials illustrate significant benefits in reductions of hyperglycemia and nonfatal cardiovascular disease, these reductions are associated with an approximate 2-fold risk of hypoglycemia.^28-30 Thus, the focus on improved glycemic control has been criticized as lacking meaning to patients in contrast to preventing T2DM complications and persevering quality of life.³¹

Limitations and Future Directions

Noted limitations include small sample size, the range of time, and a broad number of sessions given that the intervention was tailored to each veteran. Conclusions drawn from a small sample may be influenced by individual outliers. Given co-occurring conditions and moderate levels of distress, all participants may benefit from additional support resources.

In addition to these considerations, having a comparison group could further strengthen the study as part of an observational database. A between-group comparison could help clinicians better understand what the interventions offer as well as some individual factors that relate to participation and success with behavior change. In the future, studies with a priori hypotheses could also consider the trajectories of weight and blood sugar levels for extended periods; for example, 6 months before the intervention and 6 months following.³² Given the complexity of comorbid mental health and chronic medical conditions in this sample, it also may be important to measure the relationships between chronic physical symptoms as an additional barrier for veterans to make health behavior changes.

Conclusions

The authors believe that the health psychology interventions offered important support and motivation for engagement in health behavior change that led to reduced distress in this patient group. It remains a challenge to engage veterans with psychiatric conditions in mental health care, and simultaneously for health care systems that strive to reduce costs and complications associated with chronic illness management.³³ Aligned with these broader health care goals, the ADA aims to reduce complications and cost and improve outcomes for T2DM with guidelines requiring mental and behavioral health interventions. The authors believe that health psychology interventions are a personalized and feasible bridge to address engagement, illness-related distress while improving patient-satisfaction and T2DM self-management.

The goal of the study was to disseminate and implement evidence-based behavioral change strategies into a multidisciplinary team format without excluding veterans who would benefit from receiving active treatment. Due to this translational approach, a control group was not included for comparison.

Data Collection

Participants completed study measures at the beginning and end of the T2DM-focused intervention sessions. Demographic variables collected included age, sex, race/ethnicity, highest educational attainment, and whether a veteran was prescribed insulin, service connected for T2DM, concurrent enrollment in other educational programs, and time since T2DM diagnosis. Measures were selected based on their relevance to T2DM psychosocial care and diabetes health outcomes.¹³

Body mass index, low-density lipoprotein cholesterol, blood pressure (BP), HbA_1c within 3 months of the pre- and postmeasures were collected by reviewing medical records. T2DM complications were collected by self-report, and comorbid physical and mental health conditions were collected by review of the most recent primary care note. The Diabetes Empowerment Scale-Short Form (DES-SF) is a well-validated measure that was used to measure T2DM-related psychosocial self-efficacy.¹⁴ Scores ranged from 8 to 40 with higher scores indicating higher diabetes T2DM empowerment. The Patient Health Questionnaire 9-item (PHQ-9) was used to assess the frequency of somatic (fatigue, appetite, psychomotor) and cognitive symptoms (anhedonia, low mood) of depression over the past 2 weeks.¹⁵ The Generalized Anxiety Disorder 7-item (GAD-7) was used to assess the frequency of common anxiety symptoms, including feelings of worry, difficulty controlling worry, and trouble relaxing.¹⁶ Veterans were also asked to rate their general health on a 5-point Likert scale. Self-rated health is a well-established indicator of disability and risk of future T2DM complications in older adults.^17,18 The Diabetes Distress Scale (DDS) was used to measure emotional burden, physician-related distress, regimen-related distress, and T2DM-related interpersonal distress.¹⁹ Scores > 2.0 suggest clinical significant diabetes distress.²⁰ Medication questionnaires were adapted from Wilson and colleagues, 2013.²¹

Statistical Analyses

Descriptive statistics, including mean and standard deviation (SD) or frequency distributions, as appropriate, were used to characterize the sample. For pre- and postintervention within-group comparisons, a paired samples Student t test analysis was used to evaluate baseline and follow-up measures for statistically significant differences between continuous variables; scores also were evaluated for clinically meaningful change.

Results

This sample (N = 13) of older adults was predominately male, white, with HbA_1c > 7.0, and prescribed insulin (Table). On average, participants were at higher risk for future complications due to high BP, hyperlipidemia, and BMI > 30.0. Regarding participation, veterans were seen for an average of 7.8 sessions (range, 4-13) with 46% service connected for T2DM. Of note, 4 veterans received other T2DM-specific self-management support within the same year of their participation with health psychology, such as attending a T2DM education class or T2DM shared medical appointment.²² Reliability in the current sample for the DES-SF was high (Cronbach α = 0.90), PHQ-9 was good (Cronbach α = 0.81), and GAD-7 was very good (Cronbach α = 0.86).

Among the 13 older adults, the most common T2DM-related complications included peripheral neuropathy (n = 7), heart pain or heart attack (n = 5), and retinopathy (n = 4). Recent primary care notes showed a mean (SD) 7 (2.2) comorbid chronic medical conditions with a high prevalence of cardiometabolic illnesses including hypertension, hyperlipidemia, obstructive sleep apnea, and a diagnosis of chronic pain. Eleven veterans were diagnosed with a mental health condition, including bipolar disorder, depression, anxiety, trauma-related disorder, and sleep disorders. Veterans reported high T2DM emotional distress (mean [SD] 3.1 [1.2]), moderate regimen-related distress (mean [SD] 2.9 [1.1]), and moderate total T2DM distress (mean [SD] 2.4 [0.7]). Physician distress (mean [SD] 1.3 [0.55]) and interpersonal T2DM distress (mean [SD] 1.6 [0.9]) subscales indicated little to no distress. The sample reported mild symptoms of depression (PHQ-9 mean [SD] 8.8 [4.6]); mild symptoms of anxiety (GAD-7 mean, 7.1; SD, 4.4), and Diabetes Empowerment (mean, 31.2; SD, 6.0). Participants described missing an average of 2.4 days within the past 30 days of their T2DM oral medications.

Twelve veterans (92.7%) completed the Follow-up questionnaires. The Figure illustrates statistically significant changes in patient-reported outcomes between baseline and follow-up. Clinically meaningful reductions were shown in total T2DM distress (t₁₁ = 5.03, P < .01), T2DM emotional burden (t₁₁ = 4.83, P = .01), and T2DM regimen-related distress (t₁₁ = 5.14, P < .01). There was a significant increase in T2DM self-efficacy (t₁₁ = 0.32, P = .008) as well. A statistically significant reduction was seen in depressive symptoms (t₁₁ = 2.22, P = .048). While HbA_1c fell by .56 percentage points (standard error of the mean [SEM], 31; P = .10), this change was not statistically significant. Follow-up analyses also showed a clinically, though not statistically, significant reduction in weight loss by 6.9 lb. (SEM, 3.8; P = .20), and reductions of generalized anxiety by 1.2 points (SEM, 1.4; P = .42). Pre- and postanalyses did not show differences among self-rated health, physician-related burden, interpersonal-related burden, and indicators of medication taking behavior.

Discussion

This observational study evaluated change among patient-reported T2DM-specific and general distress measures and health outcomes among a small sample of veterans at VAAAHS medical center that engaged in an episode of individual care with health psychology. Statistically significant decreases were observed in T2DM-related distress. Noteworthy, these decreases were observed for the emotional burden and regimen subscales, and each of these was clinically meaningful, falling below a score of 2.0 on the T2DM-specific scale. This is important given that T2DM distress may interfere with the ability to understand and find motivation for engaging in health behavior change. Incorporating stress management interventions into interdisciplinary health programs has been demonstrated to improve not only levels of distress, but also other health outcomes, such as health related quality of life and cardiac events in heart disease.²³ Thus, behavioral health interventions that incorporate cognitive-behavioral strategies to enhance distress-specific coping may prove important to include among individuals with T2DM.

Reductions in T2DM-related distress also converged with increases observed in the T2DM empowerment scale. These significant improvements in perceived ability suggest increased self-efficacy and willingness to follow a daily T2DM regimen. This finding aligns with the social support literature that demonstrates how instrumental and other aspects of autonomous social support mediate improvements in health-related outcomes and reduced T2DM distress.^24,25 Health psychology interventions strive to both provide social support as well as enhance participants’ perceptions and use of existing support as a cognitive-behavioral strategy. Adding in assessments of social support could shed light on such mediating factors.

The ADA standards of care encourage heath care providers to engage patients in conversations in order to better understand the barriers of T2DM self-care.¹³ How to best support patients within a primary care multidisciplinary team remains unclear.²⁶ T2DM distress and negative reactions to T2DM, including symptoms of anxiety and depression, are common and may require specific referral to a mental health provider if repeated attempts at T2DM education do not improve self-management and illness biomarkers.²⁷ Thus, integrating these providers and services within the medical setting aims to reach more veterans and potentially meet these standards of care. With our health psychology integrated services, clinically significant decreases in anxiety and statistically significant decreases in depressive symptoms were observed that approached “mild to no” symptoms. Although this was not measured formally, the veterans were not engaging in mental health specialty care historically or during the year of the health psychology intervention. This suggests that health psychology services helped bridge the gap and address these psychosocial needs within the small sample.

For clinical measures, modest decreases were observed for HbA_1c and weight. The authors recognize that these changes may not be optimal in terms of health status. A review of the specific patient-centered goals may illuminate this finding. For example, 1 participant had a goal to consume fewer sugary beverages and achieved this behavior change. Yet this change alone may not equate to actual weight loss or a lower HbA_1c. Furthermore, in the context of T2DM-related distress, maintaining current weight and/or blood sugar levels may be a more realistic goal. An evaluation of the specific patient-oriented action goals and observed progress may be important outcomes to include in larger studies. Moreover, while not significant, the average HbA_1c decrease of about 1% is comparable with traditional T2DM education and should be considered in light of the sample’s significant mental health comorbidities. While landmark intensive glucose control trials illustrate significant benefits in reductions of hyperglycemia and nonfatal cardiovascular disease, these reductions are associated with an approximate 2-fold risk of hypoglycemia.^28-30 Thus, the focus on improved glycemic control has been criticized as lacking meaning to patients in contrast to preventing T2DM complications and persevering quality of life.³¹

Limitations and Future Directions

Noted limitations include small sample size, the range of time, and a broad number of sessions given that the intervention was tailored to each veteran. Conclusions drawn from a small sample may be influenced by individual outliers. Given co-occurring conditions and moderate levels of distress, all participants may benefit from additional support resources.

In addition to these considerations, having a comparison group could further strengthen the study as part of an observational database. A between-group comparison could help clinicians better understand what the interventions offer as well as some individual factors that relate to participation and success with behavior change. In the future, studies with a priori hypotheses could also consider the trajectories of weight and blood sugar levels for extended periods; for example, 6 months before the intervention and 6 months following.³² Given the complexity of comorbid mental health and chronic medical conditions in this sample, it also may be important to measure the relationships between chronic physical symptoms as an additional barrier for veterans to make health behavior changes.

Conclusions

The authors believe that the health psychology interventions offered important support and motivation for engagement in health behavior change that led to reduced distress in this patient group. It remains a challenge to engage veterans with psychiatric conditions in mental health care, and simultaneously for health care systems that strive to reduce costs and complications associated with chronic illness management.³³ Aligned with these broader health care goals, the ADA aims to reduce complications and cost and improve outcomes for T2DM with guidelines requiring mental and behavioral health interventions. The authors believe that health psychology interventions are a personalized and feasible bridge to address engagement, illness-related distress while improving patient-satisfaction and T2DM self-management.

Multiple Sclerosis (MS) is a chronic demyelinating disease of the central nervous system that affects nearly 1 million people in the US.¹ In addition to the accumulation of functional limitations, patients with MS commonly experience mental health and physical symptoms such as depression, anxiety, stress, fatigue, and pain. Day-to-day life with MS requires adaptation to challenges and active maintenance of health and well-being over time. Behavioral intervention and treatment, whether in the form of psychotherapy, health behavior coaching, or the promotion of active self-management, is an integral component of interprofessional care and key aspect of living well with MS.

Behavioral Comorbidities

Depression

Depression is a common concern among individuals with MS. Population-based studies suggest that individuals with MS have a roughly 1 in 4 chance of developing major depressive disorder over their lifetime.² However, at any given time, between 40% and 60% of individuals with MS report clinically meaningful levels of depressive symptoms.³ Although the relationship between MS disease characteristics and depression is unclear, some evidence suggests that depressive symptoms are more common at certain points in illness, such as early in the disease process as individuals grapple with the onset of new symptoms, late in the disease process as they accumulate greater disability, and during active clinical relapses.^3-5

Depression often is comorbid with, and adds to the symptom burden of, other common conditions in MS such as fatigue and cognitive dysfunction.^6-8 Thus, it is not surprising that it associated with poorer overall quality of life (QOL).⁹ Depression also is a risk factor for suicidal ideation and suicide for patients with MS.^10,11

Fortunately, several behavioral interventions show promise in treating depression in patients with MS. Both individual and group formats of cognitive behavioral therapy (CBT), a treatment focused on challenging maladaptive patterns of thought and behavior, have been shown to improve depressive symptoms for people with MS.^12,13 Several brief and efficient group-based programs grounded in CBT and focused on the development of specific skills, including problem solving, goal setting, relationship management, and managing emotions, have been shown to reduce depressive symptoms.^13,14 CBT for depression in MS has been shown to be effective when delivered via telephone.^15,16

Anxiety

Anxiety is common among individuals with MS. Existing data suggest more than one-third of individuals with MS will qualify for a diagnosis of anxiety disorder during their lifetime.¹⁷ The characteristics of anxiety disorders are broad and heterogenous, including generalized anxiety disorder, panic disorder, obsessive compulsive disorders, and health-specific phobias such as needle/injection anxiety. Some estimates suggest a point prevalence of 34% for the presence of clinically meaningful symptoms.¹⁸ Similar to depression, anxiety symptoms can be more common during periods of stress, threat, and transition including early in the disease course while adapting to new diagnosis, late in the disease course with increasing disability, and during clinical relapses.^19-21

The efficacy of behavioral interventions for anxiety in MS is less well established than it is for depression, but some preliminary evidence suggests that individual CBT may be effective for reducing general symptoms of anxiety as well as health-related anxiety.^22,23 Brief, targeted CBT also has been shown to improve injection anxiety, removing a barrier to self-care including the administration of MS disease modifying therapies (DMTs).²⁴

Stress

Stress is commonly conceptualized as a person’s perception that efforts to manage internal and external demands exceed available coping resources.²⁵ Such demands involve both psychological and physiological processes and come in many forms for people with MS and can include daily hassles, major life events, traumatic stress, and perceptions of global nonspecific stress. The relationship between stress and MS remains complex and poorly understood. Nonetheless, individuals with MS frequently report that stress exacerbates their symptoms.²⁶

Some evidence also suggests stress may exacerbate the MS disease process, resulting in more frequent relapses and increased lesion activity visible on MRI.^27,28 In addition to mindfulness (described below), stress inoculation training (CBT and relaxation training), and stress-focused group-based self-management have been shown to be beneficial.^29,30 In an intriguing and rigorous trial, a 24-week stress management therapy based on CBT was associated with the development of fewer new MS lesions visible on MRI.³¹

Adaptation to Illness

MS presents challenges that vary between patients and over time. Individuals may confront new physical and cognitive limitations that inhibit the completion of daily tasks, reduce independence, and limit participation in valued and meaningful activities. In addition, the unpredictability of the disease contributes to perceptions of uncertainty and uncontrollability, which in turn result in higher illness impact and poorer psychological outcomes.³² Building cognitive and behavioral skills to address these challenges can promote adaptation to illness and reduce overall distress associated with chronic illness.³³ Psychosocial intervention also can address the uncertainty commonly experienced by individuals with MS.³⁴

Self-Management

As with any chronic illness, living well with MS requires ongoing commitment and active engagement with health and personal care over time. The process of building knowledge and skills to manage the day-to-day physical, emotional, and social aspects of living with illness often is referred to as self-management.³⁵ For individuals with MS, this may take the form of participation in programs that address adaptation and psychological distress like those described above, but it also may include improving health behavior (eg, physical activity, DMT adherence, modification of maladaptive habits like smoking or hazardous alcohol use) and symptom management (eg, fatigue, pain). Self-management programs typically include education, the practice of identifying, problem solving, and following through with specific and realistic health and wellness goals, as well as the bolstering of self-efficacy.

Physical Activity

Once discouraged for patients with MS, physical activity is now considered a cornerstone of health and wellness. Physical activity and interventions that target various forms of exercise have been shown to improve strength and endurance, reduce functional decline, enhance QOL, and likely reduce mortality.^35-39 A variety of brief behavioral interventions have been shown to improve physical activity in MS. Structured group-based exercise classes focusing on various activities such as aerobic training (eg, cycling) or resistance training (eg, lower extremity strengthening) have demonstrated improvements in various measures of fitness and mood states such as depression and QOL. Brief home-based telephone counseling interventions based in social cognitive theory (eg, goal setting, navigating obstacles) and motivational interviewing strategies (eg, open-ended questions, affirmation, reflective listening, summarizing) also have been shown to be effective not only at increasing physical activity and improving depression and fatigue.^40,41

Adherence to Treatment

One primary focus of adherence to treatment is medication management. For individuals with MS, DMTs represent a primary means of reducing disease burden and delaying functional decline. Many DMTs require consistent self-administration over time. Some evidence suggests that poorer adherence is associated with a greater risk of relapse and more rapid disease progression.^42,43 Brief telephone counseling, again based on social cognitive theory, and principles of motivational interviewing combined with home telehealth monitoring by a care coordinator has been shown to improve adherence to DMTs.⁴⁴

Mindfulness

In recent years, mindfulness training has emerged as a popular and common behavioral intervention among individuals with MS. Programs like Mindfulness-Based Stress Reduction (MBSR) provide training in meditation techniques designed to promote mindfulness, which is defined as paying attention to present moment experience, including sensations, thoughts, and emotions, without judgment or attachment.⁴⁵ Cultivating mindfulness helps people with MS cope with and adapt to symptoms and stressors.⁴⁶ Mindfulness interventions typically are delivered in a group format. For example, MBSR consists of 8 in-person group sessions with daily meditation practice homework. Mindfulness interventions also have been delivered effectively with smartphone apps.⁴⁷ Mindfulness programs have been shown to improve depression, anxiety, fatigue, stress, and QOL for patients with MS.^48-50

Fatigue

More than 90% of individuals with MS report fatigue, and many identify it as their most disabling symptom.⁵¹ Often defined as “a subjective lack of physical and/or mental energy that is perceived by the individual or caregiver to interfere with usual and desired activities,” fatigue has been shown to be associated with longer disease duration, greater physical disability, progressive subtype, and depressive symptoms, although the relative and possibly overlapping impact of these issues is only partially understood.^52,53 Fatigue is associated with poorer overall mental health and negatively impacts work and social roles.⁵⁴

Several behavioral interventions have been developed to address fatigue in MS. Using both individual and group based formats and across several modalities (eg, in-person, telephone, online modules, or a combination), behavioral fatigue interventions most commonly combine traditional general CBT skills (eg, addressing maladaptive thoughts and behaviors) with a variety of fatigue-specific skill building exercises that may include fatigue education, energy conservation strategies, improving sleep, enlisting social support, and self-management goal setting strategies.^35,55-57

Pain

Chronic pain is common and disabling in people with MS.^58,59 Nearly 50% report experiencing moderate to severe chronic pain.^59,60 Individuals with MS reporting pain often are older, more disabled (higher Expanded Disability Status Scale score), and have longer disease duration that those who are not experiencing chronic pain.⁶¹ Patients report various types of pain in the following order of frequency: dysesthetic pain (18.1%), back pain (16.4%), painful tonic spasms (11.0%), Lhermitte sign (9.0%), visceral pain (2.9%), and trigeminal neuralgia (2.0%).⁶¹ Chronic pain has a negative impact on QOL in the areas of sleep, work, maintaining relationships, recreational activities, and overall life enjoyment.⁵⁹ Additionally, research has shown that greater pain intensity and pain-related interference with activities of daily living are both associated with greater depression severity.^62,63

The literature supports the use of behavioral interventions for pain in people with MS.⁶¹ Behavioral interventions include in-person exercise interventions (eg, water aerobics, cycling, rowing ergometer, treadmill walking, and resistance training), self-hypnosis, and telephone-based self-management programs based on CBT.^35,64,65 As described above, CBT-based self-management programs combine learning CBT skills (eg, modifying maladaptive thoughts) with pain-specific skill building such as pain education, pacing activities, and improving sleep. Of note, MS education including, but not limited to, pain was as effective as a CBT-based self-management program in reducing pain intensity and interference.³⁵ In addition, there is evidence to support acceptance- and mindfulness-based interventions for chronic pain, and online mindfulness-based cognitive therapy for MS related pain is currently being tested in a randomized controlled trial.^35,66

Conclusion

People with MS face significant challenges in coping with and adapting to a chronic and unpredictable disease. However, there is considerable evidence that behavioral interventions can improve many of the most common and disabling symptoms in MS including depression, anxiety, stress, fatigue, and pain as well as health behavior and self-care. Research also suggests that improvements in one of these problems (eg, physical inactivity) can influence improvement in other symptoms (eg, depression and fatigue). Unlike other treatment options, behavioral interventions can be delivered in various formats (eg, in-person and electronic health), are time-limited, and cause few (if any) undesirable systemic adverse effects. Behavioral interventions are therefore, an essential part of interprofessional care and rehabilitation for patients with MS.

Both individual and group formats of cognitive behavioral therapy (CBT), a treatment focused on challenging maladaptive patterns of thought and behavior, have been shown to improve depressive symptoms for people with MS.^12,13 Several brief and efficient group-based programs grounded in CBT and focused on the development of specific skills, including problem solving, goal setting, relationship management, and managing emotions, have been shown to reduce depressive symptoms.^13,14 CBT for depression in MS has been shown to be effective when delivered via telephone.^15,16

Anxiety

Anxiety is common among individuals with MS. Existing data suggest more than one-third of individuals with MS will qualify for a diagnosis of anxiety disorder during their lifetime.¹⁷ The characteristics of anxiety disorders are broad and heterogenous, including generalized anxiety disorder, panic disorder, obsessive compulsive disorders, and health-specific phobias such as needle/injection anxiety. Some estimates suggest a point prevalence of 34% for the presence of clinically meaningful symptoms.¹⁸ Similar to depression, anxiety symptoms can be more common during periods of stress, threat, and transition including early in the disease course while adapting to new diagnosis, late in the disease course with increasing disability, and during clinical relapses.^19-21

The efficacy of behavioral interventions for anxiety in MS is less well established than it is for depression, but some preliminary evidence suggests that individual CBT may be effective for reducing general symptoms of anxiety as well as health-related anxiety.^22,23 Brief, targeted CBT also has been shown to improve injection anxiety, removing a barrier to self-care including the administration of MS disease modifying therapies (DMTs).²⁴

Stress

Stress is commonly conceptualized as a person’s perception that efforts to manage internal and external demands exceed available coping resources.²⁵ Such demands involve both psychological and physiological processes and come in many forms for people with MS and can include daily hassles, major life events, traumatic stress, and perceptions of global nonspecific stress. The relationship between stress and MS remains complex and poorly understood. Nonetheless, individuals with MS frequently report that stress exacerbates their symptoms.²⁶

Some evidence also suggests stress may exacerbate the MS disease process, resulting in more frequent relapses and increased lesion activity visible on MRI.^27,28 In addition to mindfulness (described below), stress inoculation training (CBT and relaxation training), and stress-focused group-based self-management have been shown to be beneficial.^29,30 In an intriguing and rigorous trial, a 24-week stress management therapy based on CBT was associated with the development of fewer new MS lesions visible on MRI.³¹

Adaptation to Illness

MS presents challenges that vary between patients and over time. Individuals may confront new physical and cognitive limitations that inhibit the completion of daily tasks, reduce independence, and limit participation in valued and meaningful activities. In addition, the unpredictability of the disease contributes to perceptions of uncertainty and uncontrollability, which in turn result in higher illness impact and poorer psychological outcomes.³² Building cognitive and behavioral skills to address these challenges can promote adaptation to illness and reduce overall distress associated with chronic illness.³³ Psychosocial intervention also can address the uncertainty commonly experienced by individuals with MS.³⁴

Self-Management

As with any chronic illness, living well with MS requires ongoing commitment and active engagement with health and personal care over time. The process of building knowledge and skills to manage the day-to-day physical, emotional, and social aspects of living with illness often is referred to as self-management.³⁵ For individuals with MS, this may take the form of participation in programs that address adaptation and psychological distress like those described above, but it also may include improving health behavior (eg, physical activity, DMT adherence, modification of maladaptive habits like smoking or hazardous alcohol use) and symptom management (eg, fatigue, pain). Self-management programs typically include education, the practice of identifying, problem solving, and following through with specific and realistic health and wellness goals, as well as the bolstering of self-efficacy.

Physical Activity

Once discouraged for patients with MS, physical activity is now considered a cornerstone of health and wellness. Physical activity and interventions that target various forms of exercise have been shown to improve strength and endurance, reduce functional decline, enhance QOL, and likely reduce mortality.^35-39 A variety of brief behavioral interventions have been shown to improve physical activity in MS. Structured group-based exercise classes focusing on various activities such as aerobic training (eg, cycling) or resistance training (eg, lower extremity strengthening) have demonstrated improvements in various measures of fitness and mood states such as depression and QOL. Brief home-based telephone counseling interventions based in social cognitive theory (eg, goal setting, navigating obstacles) and motivational interviewing strategies (eg, open-ended questions, affirmation, reflective listening, summarizing) also have been shown to be effective not only at increasing physical activity and improving depression and fatigue.^40,41

Adherence to Treatment

One primary focus of adherence to treatment is medication management. For individuals with MS, DMTs represent a primary means of reducing disease burden and delaying functional decline. Many DMTs require consistent self-administration over time. Some evidence suggests that poorer adherence is associated with a greater risk of relapse and more rapid disease progression.^42,43 Brief telephone counseling, again based on social cognitive theory, and principles of motivational interviewing combined with home telehealth monitoring by a care coordinator has been shown to improve adherence to DMTs.⁴⁴

Mindfulness

In recent years, mindfulness training has emerged as a popular and common behavioral intervention among individuals with MS. Programs like Mindfulness-Based Stress Reduction (MBSR) provide training in meditation techniques designed to promote mindfulness, which is defined as paying attention to present moment experience, including sensations, thoughts, and emotions, without judgment or attachment.⁴⁵ Cultivating mindfulness helps people with MS cope with and adapt to symptoms and stressors.⁴⁶ Mindfulness interventions typically are delivered in a group format. For example, MBSR consists of 8 in-person group sessions with daily meditation practice homework. Mindfulness interventions also have been delivered effectively with smartphone apps.⁴⁷ Mindfulness programs have been shown to improve depression, anxiety, fatigue, stress, and QOL for patients with MS.^48-50

Fatigue

More than 90% of individuals with MS report fatigue, and many identify it as their most disabling symptom.⁵¹ Often defined as “a subjective lack of physical and/or mental energy that is perceived by the individual or caregiver to interfere with usual and desired activities,” fatigue has been shown to be associated with longer disease duration, greater physical disability, progressive subtype, and depressive symptoms, although the relative and possibly overlapping impact of these issues is only partially understood.^52,53 Fatigue is associated with poorer overall mental health and negatively impacts work and social roles.⁵⁴

Several behavioral interventions have been developed to address fatigue in MS. Using both individual and group based formats and across several modalities (eg, in-person, telephone, online modules, or a combination), behavioral fatigue interventions most commonly combine traditional general CBT skills (eg, addressing maladaptive thoughts and behaviors) with a variety of fatigue-specific skill building exercises that may include fatigue education, energy conservation strategies, improving sleep, enlisting social support, and self-management goal setting strategies.^35,55-57

Pain

Chronic pain is common and disabling in people with MS.^58,59 Nearly 50% report experiencing moderate to severe chronic pain.^59,60 Individuals with MS reporting pain often are older, more disabled (higher Expanded Disability Status Scale score), and have longer disease duration that those who are not experiencing chronic pain.⁶¹ Patients report various types of pain in the following order of frequency: dysesthetic pain (18.1%), back pain (16.4%), painful tonic spasms (11.0%), Lhermitte sign (9.0%), visceral pain (2.9%), and trigeminal neuralgia (2.0%).⁶¹ Chronic pain has a negative impact on QOL in the areas of sleep, work, maintaining relationships, recreational activities, and overall life enjoyment.⁵⁹ Additionally, research has shown that greater pain intensity and pain-related interference with activities of daily living are both associated with greater depression severity.^62,63

The literature supports the use of behavioral interventions for pain in people with MS.⁶¹ Behavioral interventions include in-person exercise interventions (eg, water aerobics, cycling, rowing ergometer, treadmill walking, and resistance training), self-hypnosis, and telephone-based self-management programs based on CBT.^35,64,65 As described above, CBT-based self-management programs combine learning CBT skills (eg, modifying maladaptive thoughts) with pain-specific skill building such as pain education, pacing activities, and improving sleep. Of note, MS education including, but not limited to, pain was as effective as a CBT-based self-management program in reducing pain intensity and interference.³⁵ In addition, there is evidence to support acceptance- and mindfulness-based interventions for chronic pain, and online mindfulness-based cognitive therapy for MS related pain is currently being tested in a randomized controlled trial.^35,66

Conclusion

People with MS face significant challenges in coping with and adapting to a chronic and unpredictable disease. However, there is considerable evidence that behavioral interventions can improve many of the most common and disabling symptoms in MS including depression, anxiety, stress, fatigue, and pain as well as health behavior and self-care. Research also suggests that improvements in one of these problems (eg, physical inactivity) can influence improvement in other symptoms (eg, depression and fatigue). Unlike other treatment options, behavioral interventions can be delivered in various formats (eg, in-person and electronic health), are time-limited, and cause few (if any) undesirable systemic adverse effects. Behavioral interventions are therefore, an essential part of interprofessional care and rehabilitation for patients with MS.

According to World Health Organization estimates, 65 million people have moderate-to-severe chronic obstructive pulmonary disease (COPD) globally, and > 20 million patients with COPD are living in the US.¹ COPD is a progressive respiratory disease with a poor prognosis and a significant cause of morbidity and mortality in the US, especially within the Veterans Health Administration (VHA).² The prevalence of COPD is higher in veterans than it is in the general population. COPD prevalence in the adult US population has been estimated to be between 5% and 15%, whereas in veterans, prevalence estimates have ranged from about 5% to 43%.^3-5

COPD is associated with disabling dyspnea, muscle weakness, exercise intolerance, morbidity, and mortality. These symptoms and complications gradually and progressively compromise mobility, ability to perform daily functions, and decrease quality of life (QOL). Dyspnea, fatigue, and discomfort are the principal symptoms that negatively impact exercise tolerance.^6,7 Therefore, patients often intentionally limit their activities to avoid these uncomfortable feelings and adopt a more sedentary behavior. As the disease progresses, individuals with COPD will gradually need assistance in performing activities of daily living, which eventually leads to functional dependence.

Pulmonary rehabilitation (PR) is an essential component of the management of symptomatic patients with COPD. PR is an evidence-based, multidisciplinary, comprehensive intervention that includes exercise and education for patients with chronic respiratory disease.⁸ The key benefits of PR are clinical improvements in dyspnea, physical capacity, QOL, and reduced disability in patients with COPD and other respiratory diseases.^9-11 PR was found to improve respiratory health in veterans with COPD and decrease respiratory-related health care utilization.¹²

Despite the known benefits of PR, many patients with chronic respiratory diseases are not referred or do not have access to rehabilitation. Also, uptake of PR is low due to patient frailty, transportation issues, and other health care access problems.^13-15 Unfortunately, in the US health care system, access to PR and other nonpharmacologic treatments can be challenging due to a shortage of available PR programs, limited physician referral to existing programs, and lack of family and social support.¹⁶

There are only a few accredited PR programs in VHA facilities, and they tend to be located in urban areas.^12,17 Many patients have limited access to the PR programs due to geographic distance to the programs and transportation challenges (eg, limited ability to drive, cost of transportation). Moreover, veterans with COPD are likely to have limited mobility or are homebound due to experiencing shortness of breath with minimal exertion. Given the clear benefits of PR and the increasing impact of COPD on morbidity and mortality of the patients with COPD, strategies to improve the access and capacity of PR are needed. VA telehealth services allow for distribution of health care services in different geographic locations by providing access for the veterans who live in rural and highly rural areas. The most recent implementation of VA Video Connect (VVC) by the VHA provides a new avenue for clinicians to deliver much needed medical care into the veterans’ home.

COPD Telehealth Program

In this article, we describe the processes for developing and delivering an in-home, interactive, supervised PR program for veterans with severe COPD through VA telehealth service. The program consists of 18 sessions delivered over 6 weeks by a licensed physical therapist (PT) and a respiratory therapist (RT). The aims of the telehealth PR are to improve exercise tolerance, reduce dyspnea and fatigue, improve QOL, improve accessibility, and decrease costs and transportation burdens for patients with COPD. The program was developed, implemented and delivered by an interdisciplinary team, including a pulmonologist, PT, RT, physiatrist, and nonclinical supporting staff.

To be eligible to participate in the program the patient must: (1) have a forced expiratory volume (FEV₁) < 60%; ( 2) be medically stable and be receiving optimal medical management; (3) have no severe cognitive impairments; (4) be able to use a computer and e-mail; (5) be able to ambulate with or without a walking device; (6) be willing to enroll in a smoking cessation program or to stop smoking; (7) be willing to participate without prolonged interruption; and (8) have all visual and auditory impairments corrected with medical devices.

After referral and enrollment, patients receive medical and physical examinations by the PR team, including a pulmonologist, a PT, and a RT, to ensure that the patients are medically stable to undergo rehabilitation and to develop a tailored exercise program while being mindful of the comorbidities, limitations, and precautions, (eg, loss of balance, risk of fall, limited range of motion). The preprogram assessment includes a pulmonary function test, arterial blood gas test, Montreal Cognitive Assessment, Modified Medical Research Council Scale, St. George Respiratory Questionnaire, the COPD Assessment Test, Patient Health Questionnaire-9,Generalized Anxiety Disorder Assessment-7, Epworth Sleepiness Scale, Katz Index of Independence of Activities of Daily Living, medications and inhaler use, oxygen use, breathing pattern, coughing, 6-minute walk test, Modified Borg Dyspnea Scale, grip strength, 5 Times Sit to Stand Test, manual muscle test, gait measure, Timed Up & Go test, clinical balance tests, range of motion, flexibility, sensation, pain, and fall history.^18-32 Educational needs (eg, respiratory hygiene, nutrition, infection control, sleep, disease/symptom management) also are evaluated.

This thorough assessment is performed in a face-to-face outpatient visit. During the program participation, a physiatrist may be consulted for additional needs (eg, wheelchair assessment, home safety evaluation/ modifications, and mobility/disability issues). After completing the 6-week program, patients are scheduled for the postprogram evaluation in a face-to-face outpatient visit with the clinicians.

Equipment

Both clinician and the patient are equipped with a computer with Wi-Fi connectivity, a webcam, and a microphone. Patients are provided an exercise pictorial booklet, an exercise compact disk (audio and video), small exercise apparatuses (eg, assorted colors of resistance bands, hand grip exerciser, hand putty, ergometer, harmonica, and pedometer), incentive spirometer, pulse oximeter, cough assistive device (as needed), blood pressure monitor, COPD information booklets, and a diary to use at home during the program.³³

Technology Preparation

Prior to starting the telehealth program, the patient is contacted 1 or 2 days before the first session for technical preparation and familiarization of the VA telehealth connection process. Either the PT or RT provides step-by-step instructions for the patient to practice connecting through VVC during this preparatory phone call. The patient also practices using the computer webcam, speaker, and microphone; checks the telehealth scheduling e-mail; and learns how to solve possible common technical issues (eg, adjusting volume and position of webcam). The patient is asked to set up a table close to the computer and to place all exercise apparatuses and respiratory devices on the table surface.

Program Delivery

A secure online VVC is used for connection during the telehealth session. The patient received an e-mail from the telehealth scheduling system with a link for VVC before each session. During the 6-week program, each telehealth session is conducted by a PT and a RT concurrently for 120 minutes, 3 days per week. The PT provides exercises for the patient to attempt, and the RT provides breathing training and monitoring during the session. After a successful connection to VVC, the therapist verifies the patient’s identity and confirms patient consent for the telehealth session.

After this check-in process, the patient performs a self-measure of resting blood pressure (BP), heart rate, respiratory rate, and blood oxygen saturation and reports to the therapists. During the exercise session, fatigue/exertion, dyspnea (Modified Borg Dyspnea Scale; Borg CR10 Scale), BP, heart rate, oxygen saturation, and other clinical symptoms and responses to exercise are monitored by the therapists, using both patient-reported measures and clinical observation by the therapists.^34,35 Any medical emergency during the session is reported immediately to the pulmonologist for further management.

Structure

Prior to each exercise session, exercise precautions, fall prevention, good posture, pursed-lip breathing, pacing, and coordinated breathing are discussed with the patient. The PT demonstrates stretching and warm-up exercises in front of the webcam for the patient to follow. Then the patient performs all exercises in view of the webcam during the session (Figure 1). A RT monitors breathing patterns and corrects with verbal instructions if not properly performed.

Loss of skeletal muscle mass and cachexia are highly prevalent comorbidities of COPD and have been associated with breathlessness, functional limitation, and poor prognosis.³⁶ To address these comorbidities, our program consists of progressive strengthening, aerobic, balance, and flexibility exercises. Resistance bands and tubes are used for strengthening exercises. Callisthenic exercises (eg, chair squat, chair stand, knee marching, bridging, single limb stances, and lunge) are used for progressive strengthening and balance exercises. Progression of strengthening and balance exercises are done through increasing the volume of exercise (ie, numbers of sets and repetitions) and increased load and level of difficulty based on the patient’s progress and comorbidity. The exercise program focuses on strengthening muscles, especially large muscle groups, to improve overall muscle strength and performance of functional activities.³⁷

Arm/pedal ergometer and daily walking are used for daily aerobic exercise. In a study of patients with COPD by the PAC-COPD Study Group, step counter use was found to increase physical activity and improve exercise capacity, which supports its use in COPD management.³⁸ During program participation, the patient is asked to wear a pedometer to monitor the number of steps taken per day and to report step data to the therapists during the telehealth session. The pedometer stores the previous 41 calendar days of data and displays the most recent 7 calendar days of data.

The patient is encouraged to set a realistic daily step goal. The general program goal is to increase at least 1000 steps per day. However, this goal can be adjusted depending on the patient’s health status and comorbid conditions. The PAC-COPD Study Group found that for every additional 1000 daily steps at low intensity, COPD hospitalization risk decreased by 20%.³⁹ A magnitude of 2000 steps or about 1 mile of walking per day was found to be associated with increased physical activity and health benefits in the general population.⁴⁰

fed03609430_f2.png

Respiratory muscle training and breathing exercise are provided by the RT, using breathing and incentive spirometer techniques (Figure 2). Huff coughing, diaphragmatic deep breathing, and pursed-lip breathing are instructed by the RT during the session. Effective coughing technique with a cough assistive device is also provided during breathing training if needed.

Patient Education

In patients with COPD, there are numerous positive health benefits associated with education, including assisting the patients to become active participants in the PR program leading to satisfying outcomes; assisting the patients to better understand the lung health, disease processes, physical and psychological changes that occur with COPD; assisting the patients to explore coping strategies for those changes; building lifelong behavioral changes; and developing the self-management skills for sustainability. Through the educational process, patients with COPD can become more skilled at collaborative self-management and improve adherence to their treatment plan, which in turn can result in a reduction in hospital admissions and reduced health care costs.^8,41

fed03609430_f3.png

Education is provided with every session after the patient completes the exercise. Patients are required to record their COPD symptoms, daily activity, home exercise program, sleep, food intake, and additional physical or social activity in their COPD diary and to report during the session (Figure 3). A COPD diary assists patients in self-monitoring their COPD symptoms and provides the therapists with information about clinical changes, behavioral changes, and/or specific unmet needs for education. Several topics related to COPD are included in the education session: lung or respiratory disease/condition and self-management; smoking cessation; physical activity; energy-conserving techniques; breathing and coughing techniques; smoking cessation; nutrition/healthy eating and weight counseling; sex and intimacy; psychological counseling and/or group support; emergency planning (eg, medical, travel, and inclement weather); correct use of inhaler and medications; home oxygen; sleep and sleep hygiene; palliative care and advanced directive; infection control; and sputum clearance.^42,43

Program Maintenance

After successfully completing the 6-week program, patients are referred to the VA TeleMOVE! Program or MOVE! Weight Management Program for continuous, long-term management of weight, nutrition, physical activity/exercise, and social activity needs or goals. The patients are scheduled for monthly follow-up phone visits for 6 months with the telerehabilitation team for enforcing sustainability. The phone call visit consists of reviewing breathing techniques, exercise program, physical activity, education, encouragement, and addressing any issues that arise during the self-maintained period.

Limitations

There are several issues of concern and precautions when delivering PR through telehealth into the home. First, the patient performs exercises independently without being manually guarded by the therapists. Risk of falls are a major concern due to impaired balance, poor vision, and other possible unusual physiologic responses to exercise (eg, drop in BP, dizziness, loss of balance). The area in front of the computer needs to be cleared of fall hazards (ie, area rug, wires, objects on the floor). The patient also needs to be educated on self-measurements of BP and oxygen saturation and reports to the therapists. The therapists provide detailed instructions on how to obtain these measures correctly; otherwise, the values may not be valid for a clinical judgment during the exercise session or for other clinical management. In a home environment, there is a limited use of exercise apparatuses. For this program, we only used resistance bands/tubes, small arm/leg ergometer, hand grip, and hand putty for the exercise program. We feel that dumbbell and weight plates are not suitable due to a possible risk of injury if the patient accidently drops them.

Advanced balance training is not suitable due to an increased risk for falls. Without the presence of the PT, level of challenge/difficulty is somewhat limited for this telehealth supervision exercise program. In addition, visual and audio quality are necessary for the session. The patient and the therapists need to see each other clearly to ensure correct methods and forms of each exercise. Furthermore, rehearsal of technical skills with the therapists is very important because this population is older and often has limited computer skills. Any technical difficulty or failure can lead to undesirable situations (eg, anxiety episodes, worries, shortness of breath, upset), which compromise exercise performance during the session. Finally, a phone is needed as an alternative in case of a poor VVC connection.

Conclusion

COPD symptoms and complications greatly affect patients’ ability to perform daily activities, decrease QOL and functional ability, and result in extensive use of health services. Many patients have limited access to a PR program at hospitals or rehabilitation centers due to health conditions, lack of transportation, and/or family support. This home-based, interactive telehealth PR program can break down the geographic barriers, solve poor program accessibility, potentially increase the utilization of PR, and reduce the cost and travel required by the patients.

Patients are required to record their COPD symptoms, daily activity, home exercise program, sleep, food intake, and additional physical or social activity in their COPD diary and to report during the session (Figure 3). A COPD diary assists patients in self-monitoring their COPD symptoms and provides the therapists with information about clinical changes, behavioral changes, and/or specific unmet needs for education. Several topics related to COPD are included in the education session: lung or respiratory disease/condition and self-management; smoking cessation; physical activity; energy-conserving techniques; breathing and coughing techniques; smoking cessation; nutrition/healthy eating and weight counseling; sex and intimacy; psychological counseling and/or group support; emergency planning (eg, medical, travel, and inclement weather); correct use of inhaler and medications; home oxygen; sleep and sleep hygiene; palliative care and advanced directive; infection control; and sputum clearance.^42,43

Program Maintenance

After successfully completing the 6-week program, patients are referred to the VA TeleMOVE! Program or MOVE! Weight Management Program for continuous, long-term management of weight, nutrition, physical activity/exercise, and social activity needs or goals. The patients are scheduled for monthly follow-up phone visits for 6 months with the telerehabilitation team for enforcing sustainability. The phone call visit consists of reviewing breathing techniques, exercise program, physical activity, education, encouragement, and addressing any issues that arise during the self-maintained period.

Limitations

There are several issues of concern and precautions when delivering PR through telehealth into the home. First, the patient performs exercises independently without being manually guarded by the therapists. Risk of falls are a major concern due to impaired balance, poor vision, and other possible unusual physiologic responses to exercise (eg, drop in BP, dizziness, loss of balance). The area in front of the computer needs to be cleared of fall hazards (ie, area rug, wires, objects on the floor). The patient also needs to be educated on self-measurements of BP and oxygen saturation and reports to the therapists. The therapists provide detailed instructions on how to obtain these measures correctly; otherwise, the values may not be valid for a clinical judgment during the exercise session or for other clinical management. In a home environment, there is a limited use of exercise apparatuses. For this program, we only used resistance bands/tubes, small arm/leg ergometer, hand grip, and hand putty for the exercise program. We feel that dumbbell and weight plates are not suitable due to a possible risk of injury if the patient accidently drops them.

Advanced balance training is not suitable due to an increased risk for falls. Without the presence of the PT, level of challenge/difficulty is somewhat limited for this telehealth supervision exercise program. In addition, visual and audio quality are necessary for the session. The patient and the therapists need to see each other clearly to ensure correct methods and forms of each exercise. Furthermore, rehearsal of technical skills with the therapists is very important because this population is older and often has limited computer skills. Any technical difficulty or failure can lead to undesirable situations (eg, anxiety episodes, worries, shortness of breath, upset), which compromise exercise performance during the session. Finally, a phone is needed as an alternative in case of a poor VVC connection.

Conclusion

COPD symptoms and complications greatly affect patients’ ability to perform daily activities, decrease QOL and functional ability, and result in extensive use of health services. Many patients have limited access to a PR program at hospitals or rehabilitation centers due to health conditions, lack of transportation, and/or family support. This home-based, interactive telehealth PR program can break down the geographic barriers, solve poor program accessibility, potentially increase the utilization of PR, and reduce the cost and travel required by the patients.

According to World Health Organization estimates, 65 million people have moderate-to-severe chronic obstructive pulmonary disease (COPD) globally, and > 20 million patients with COPD are living in the US.¹ COPD is a progressive respiratory disease with a poor prognosis and a significant cause of morbidity and mortality in the US, especially within the Veterans Health Administration (VHA).² The prevalence of COPD is higher in veterans than it is in the general population. COPD prevalence in the adult US population has been estimated to be between 5% and 15%, whereas in veterans, prevalence estimates have ranged from about 5% to 43%.^3-5

COPD is associated with disabling dyspnea, muscle weakness, exercise intolerance, morbidity, and mortality. These symptoms and complications gradually and progressively compromise mobility, ability to perform daily functions, and decrease quality of life (QOL). Dyspnea, fatigue, and discomfort are the principal symptoms that negatively impact exercise tolerance.^6,7 Therefore, patients often intentionally limit their activities to avoid these uncomfortable feelings and adopt a more sedentary behavior. As the disease progresses, individuals with COPD will gradually need assistance in performing activities of daily living, which eventually leads to functional dependence.

Pulmonary rehabilitation (PR) is an essential component of the management of symptomatic patients with COPD. PR is an evidence-based, multidisciplinary, comprehensive intervention that includes exercise and education for patients with chronic respiratory disease.⁸ The key benefits of PR are clinical improvements in dyspnea, physical capacity, QOL, and reduced disability in patients with COPD and other respiratory diseases.^9-11 PR was found to improve respiratory health in veterans with COPD and decrease respiratory-related health care utilization.¹²

Despite the known benefits of PR, many patients with chronic respiratory diseases are not referred or do not have access to rehabilitation. Also, uptake of PR is low due to patient frailty, transportation issues, and other health care access problems.^13-15 Unfortunately, in the US health care system, access to PR and other nonpharmacologic treatments can be challenging due to a shortage of available PR programs, limited physician referral to existing programs, and lack of family and social support.¹⁶

There are only a few accredited PR programs in VHA facilities, and they tend to be located in urban areas.^12,17 Many patients have limited access to the PR programs due to geographic distance to the programs and transportation challenges (eg, limited ability to drive, cost of transportation). Moreover, veterans with COPD are likely to have limited mobility or are homebound due to experiencing shortness of breath with minimal exertion. Given the clear benefits of PR and the increasing impact of COPD on morbidity and mortality of the patients with COPD, strategies to improve the access and capacity of PR are needed. VA telehealth services allow for distribution of health care services in different geographic locations by providing access for the veterans who live in rural and highly rural areas. The most recent implementation of VA Video Connect (VVC) by the VHA provides a new avenue for clinicians to deliver much needed medical care into the veterans’ home.

COPD Telehealth Program

In this article, we describe the processes for developing and delivering an in-home, interactive, supervised PR program for veterans with severe COPD through VA telehealth service. The program consists of 18 sessions delivered over 6 weeks by a licensed physical therapist (PT) and a respiratory therapist (RT). The aims of the telehealth PR are to improve exercise tolerance, reduce dyspnea and fatigue, improve QOL, improve accessibility, and decrease costs and transportation burdens for patients with COPD. The program was developed, implemented and delivered by an interdisciplinary team, including a pulmonologist, PT, RT, physiatrist, and nonclinical supporting staff.

To be eligible to participate in the program the patient must: (1) have a forced expiratory volume (FEV₁) < 60%; ( 2) be medically stable and be receiving optimal medical management; (3) have no severe cognitive impairments; (4) be able to use a computer and e-mail; (5) be able to ambulate with or without a walking device; (6) be willing to enroll in a smoking cessation program or to stop smoking; (7) be willing to participate without prolonged interruption; and (8) have all visual and auditory impairments corrected with medical devices.

After referral and enrollment, patients receive medical and physical examinations by the PR team, including a pulmonologist, a PT, and a RT, to ensure that the patients are medically stable to undergo rehabilitation and to develop a tailored exercise program while being mindful of the comorbidities, limitations, and precautions, (eg, loss of balance, risk of fall, limited range of motion). The preprogram assessment includes a pulmonary function test, arterial blood gas test, Montreal Cognitive Assessment, Modified Medical Research Council Scale, St. George Respiratory Questionnaire, the COPD Assessment Test, Patient Health Questionnaire-9,Generalized Anxiety Disorder Assessment-7, Epworth Sleepiness Scale, Katz Index of Independence of Activities of Daily Living, medications and inhaler use, oxygen use, breathing pattern, coughing, 6-minute walk test, Modified Borg Dyspnea Scale, grip strength, 5 Times Sit to Stand Test, manual muscle test, gait measure, Timed Up & Go test, clinical balance tests, range of motion, flexibility, sensation, pain, and fall history.^18-32 Educational needs (eg, respiratory hygiene, nutrition, infection control, sleep, disease/symptom management) also are evaluated.

This thorough assessment is performed in a face-to-face outpatient visit. During the program participation, a physiatrist may be consulted for additional needs (eg, wheelchair assessment, home safety evaluation/ modifications, and mobility/disability issues). After completing the 6-week program, patients are scheduled for the postprogram evaluation in a face-to-face outpatient visit with the clinicians.

Equipment

Both clinician and the patient are equipped with a computer with Wi-Fi connectivity, a webcam, and a microphone. Patients are provided an exercise pictorial booklet, an exercise compact disk (audio and video), small exercise apparatuses (eg, assorted colors of resistance bands, hand grip exerciser, hand putty, ergometer, harmonica, and pedometer), incentive spirometer, pulse oximeter, cough assistive device (as needed), blood pressure monitor, COPD information booklets, and a diary to use at home during the program.³³

Technology Preparation

Prior to starting the telehealth program, the patient is contacted 1 or 2 days before the first session for technical preparation and familiarization of the VA telehealth connection process. Either the PT or RT provides step-by-step instructions for the patient to practice connecting through VVC during this preparatory phone call. The patient also practices using the computer webcam, speaker, and microphone; checks the telehealth scheduling e-mail; and learns how to solve possible common technical issues (eg, adjusting volume and position of webcam). The patient is asked to set up a table close to the computer and to place all exercise apparatuses and respiratory devices on the table surface.

Program Delivery

A secure online VVC is used for connection during the telehealth session. The patient received an e-mail from the telehealth scheduling system with a link for VVC before each session. During the 6-week program, each telehealth session is conducted by a PT and a RT concurrently for 120 minutes, 3 days per week. The PT provides exercises for the patient to attempt, and the RT provides breathing training and monitoring during the session. After a successful connection to VVC, the therapist verifies the patient’s identity and confirms patient consent for the telehealth session.

After this check-in process, the patient performs a self-measure of resting blood pressure (BP), heart rate, respiratory rate, and blood oxygen saturation and reports to the therapists. During the exercise session, fatigue/exertion, dyspnea (Modified Borg Dyspnea Scale; Borg CR10 Scale), BP, heart rate, oxygen saturation, and other clinical symptoms and responses to exercise are monitored by the therapists, using both patient-reported measures and clinical observation by the therapists.^34,35 Any medical emergency during the session is reported immediately to the pulmonologist for further management.

Structure

Prior to each exercise session, exercise precautions, fall prevention, good posture, pursed-lip breathing, pacing, and coordinated breathing are discussed with the patient. The PT demonstrates stretching and warm-up exercises in front of the webcam for the patient to follow. Then the patient performs all exercises in view of the webcam during the session (Figure 1). A RT monitors breathing patterns and corrects with verbal instructions if not properly performed.

Loss of skeletal muscle mass and cachexia are highly prevalent comorbidities of COPD and have been associated with breathlessness, functional limitation, and poor prognosis.³⁶ To address these comorbidities, our program consists of progressive strengthening, aerobic, balance, and flexibility exercises. Resistance bands and tubes are used for strengthening exercises. Callisthenic exercises (eg, chair squat, chair stand, knee marching, bridging, single limb stances, and lunge) are used for progressive strengthening and balance exercises. Progression of strengthening and balance exercises are done through increasing the volume of exercise (ie, numbers of sets and repetitions) and increased load and level of difficulty based on the patient’s progress and comorbidity. The exercise program focuses on strengthening muscles, especially large muscle groups, to improve overall muscle strength and performance of functional activities.³⁷

Arm/pedal ergometer and daily walking are used for daily aerobic exercise. In a study of patients with COPD by the PAC-COPD Study Group, step counter use was found to increase physical activity and improve exercise capacity, which supports its use in COPD management.³⁸ During program participation, the patient is asked to wear a pedometer to monitor the number of steps taken per day and to report step data to the therapists during the telehealth session. The pedometer stores the previous 41 calendar days of data and displays the most recent 7 calendar days of data.

The patient is encouraged to set a realistic daily step goal. The general program goal is to increase at least 1000 steps per day. However, this goal can be adjusted depending on the patient’s health status and comorbid conditions. The PAC-COPD Study Group found that for every additional 1000 daily steps at low intensity, COPD hospitalization risk decreased by 20%.³⁹ A magnitude of 2000 steps or about 1 mile of walking per day was found to be associated with increased physical activity and health benefits in the general population.⁴⁰

fed03609430_f2.png

Respiratory muscle training and breathing exercise are provided by the RT, using breathing and incentive spirometer techniques (Figure 2). Huff coughing, diaphragmatic deep breathing, and pursed-lip breathing are instructed by the RT during the session. Effective coughing technique with a cough assistive device is also provided during breathing training if needed.

Patient Education

In patients with COPD, there are numerous positive health benefits associated with education, including assisting the patients to become active participants in the PR program leading to satisfying outcomes; assisting the patients to better understand the lung health, disease processes, physical and psychological changes that occur with COPD; assisting the patients to explore coping strategies for those changes; building lifelong behavioral changes; and developing the self-management skills for sustainability. Through the educational process, patients with COPD can become more skilled at collaborative self-management and improve adherence to their treatment plan, which in turn can result in a reduction in hospital admissions and reduced health care costs.^8,41

fed03609430_f3.png

Education is provided with every session after the patient completes the exercise. Patients are required to record their COPD symptoms, daily activity, home exercise program, sleep, food intake, and additional physical or social activity in their COPD diary and to report during the session (Figure 3). A COPD diary assists patients in self-monitoring their COPD symptoms and provides the therapists with information about clinical changes, behavioral changes, and/or specific unmet needs for education. Several topics related to COPD are included in the education session: lung or respiratory disease/condition and self-management; smoking cessation; physical activity; energy-conserving techniques; breathing and coughing techniques; smoking cessation; nutrition/healthy eating and weight counseling; sex and intimacy; psychological counseling and/or group support; emergency planning (eg, medical, travel, and inclement weather); correct use of inhaler and medications; home oxygen; sleep and sleep hygiene; palliative care and advanced directive; infection control; and sputum clearance.^42,43

Program Maintenance

After successfully completing the 6-week program, patients are referred to the VA TeleMOVE! Program or MOVE! Weight Management Program for continuous, long-term management of weight, nutrition, physical activity/exercise, and social activity needs or goals. The patients are scheduled for monthly follow-up phone visits for 6 months with the telerehabilitation team for enforcing sustainability. The phone call visit consists of reviewing breathing techniques, exercise program, physical activity, education, encouragement, and addressing any issues that arise during the self-maintained period.

The National Defense Appropriations Act for fiscal year 2009, Subtitle B, waived copayments for preventive cancer screening services for all TRICARE beneficiaries, excluding Medicare-eligible beneficiaries.¹ These preventive services include screening for colorectal cancer (CRC), breast cancer, and cervical cancer based on current guidelines (eAppendix1).

Despite having unrestricted access to these cancer screenings, TRICARE Prime beneficiaries report overall screening completion rates that are below the national commercial benchmarks established by the Healthcare Effectiveness Data and Information Set (HEDIS) for all 3 cancer types.² Specifically, among TRICARE Prime beneficiaries enrolled in the western region of the U.S. in October 2013, the reported breast cancer screening rate was 61.6% (43,138/69,976) for women aged 42 to 69 years, which is well below the HEDIS 75th percentile of 76%. Similarly, the reported rate of cervical cancer screening among women aged 24 to 64 years was 68.3% (63,523/92,946), well below the HEDIS 75th percentile of 79%. Last, the reported rate of CRC screening among male and female TRICARE Prime members aged 51 to 75 years was 61.6% (52,860/85,827), also below the 2013 HEDIS 75th percentile of 63% based on internal review of TRICARE data used for HEDIS reporting.

Given the reported low screening rates, the Defense Health Agency (DHA) performed a cross-sectional survey to assess TRICARE Prime West region beneficiaries’ knowledge and understanding of preventive health screening, specifically for breast cancer, cervical cancer, and CRC, and to identify any potential barriers to access for these screenings.

Methods

A mostly closed-ended, 42-item telephone survey was designed and conducted (eAppendix2)

All women participating in the survey, regardless of age, were asked questions regarding cervical cancer screening. Women aged ≥ 42 years additionally were asked a second set of survey questions specific to breast cancer screening, and women aged between 51 and 64 years were asked a third set of questions related to CRC screening. The ages selected were 1 to 2 years after the recommended age for the respective screening to ensure adequate follow-up time for the member to obtain the screening. Men included in the survey were asked questions related only to CRC screening.

The target survey sample was 3,500 beneficiaries, separated into the following 4 strata: women aged 21 to 64 years of age enrolled in the direct care system (n = 1,250); women aged 21 to 64 years enrolled in the purchased (commercial) care network (n = 1,250); men aged 51 to 64 years enrolled in the direct care system (n = 500); and men aged 51 to 64 years enrolled in the purchased care network (n = 500). The random sample was drawn from an overall population of about 35,000 members. Sampling was performed without replacement until the target number of surveys was achieved. Survey completion was defined as the respondent having reached the end of the survey questionnaire but not necessarily having answered every question.

Data Elements

The preventive health survey collected information on beneficiaries’ knowledge of and satisfaction with their PCM, the primary location where they sought health care in the previous 12 months, preference for scheduling cancer screening tests, and general knowledge about the frequency and type of screening for breast, cervical, and colorectal cancers. Responses were scored based on guidelines effective as of 2009. In addition, the survey collected information on the beneficiary’s overall health status, current age, highest level of education achieved, current employment status, place of residence (on or off a military installation), race, and whether the beneficiary carried other health insurance aside from TRICARE.

Survey Mode and Fielding

A sampling population of eligible beneficiaries was created from a database of all TRICARE Prime beneficiaries. An automated system was used to randomly draw potential participants from the sample. Survey interviewers were given the beneficiary’s name and telephone number but no other identifiable information. Phone numbers from the sample were dialed up to 6 times before the number was classified as a “no answer.” Interviewers read to each beneficiary a statement describing the survey and participation risk and benefits and explained that participation was voluntary and the participant could end the survey at any time without penalty or prejudice. The survey commenced only after verbal consent was obtained.

Sample Weighting and Statistical Analysis

Each survey record was weighted to control for potential bias associated with unequal rates of noncoverage and nonresponse in the sampled population. A design weight was calculated as the ratio of the frame size and the sample size in each stratum. For each stratum, an adjusted response rate (RR) was calculated as the number of completed surveys divided by the number of eligible respondents. Since all respondents were eligible, the RR was not adjusted. The ratio of the design weight to the adjusted RR was calculated and assigned to each survey.

Frequency distributions and descriptive statistics were calculated for all close-ended survey items. Open-ended survey items were summarized and assessed qualitatively. When appropriate, open-ended responses were categorized and included in descriptive analyses. No formal statistical testing was performed.

Results

A total of 6,563 beneficiaries were contacted, and 3,688 agreed to participate (56%), resulting in 3,500 TRICARE beneficiaries completing the survey (95% completion rate), of whom 71% (2,500) were female. The overall cooperation rates were similar across the 4 strata. Interviews ceased once 3,500 surveys were completed. The largest distribution of respondents was aged between 55 and 64 years (37%) (Table 1). Respondents aged 21 to 24 years comprised the smallest percentage of the sample (7%). Nearly a third of respondents were dependents of ADSMs (30%), another 30% were retirees, and most respondents self-identified as white (Table 1).

fed03403050s_t1.png

Barriers to Screening

A series of survey questions was asked about specific barriers to cancer screening, including the convenience of appointment times for the respondent’s last cancer screening. The majority (69%, 2,415 of 3,500) responded that the appointment times were convenient. Among those who stated that times were not convenient and those who had not scheduled an examination, 66% responded that they did not know or were not sure how to schedule a cancer screening test.

Screening Preferences

Less than half of survey respondents (48%) reported that they received screening guideline information from their physician or provider; 24% reported that they performed their own research. Only 9% reported that they learned about the guidelines through TRICARE materials, and 7% of respondents indicated that media, family, or friends were their source of screening information.

The survey respondents who indicated that they had not scheduled a screening examination were asked when (time of day) they preferred to have a screening. Less than half (47%) reported that varying available appointment times would not affect their ability to obtain screening. One-quarter preferred times for screening during working hours, 20% preferred times after working hours, 6% preferred times before working hours, and 2% responded that they were unsure or did not know. The majority (89%) reported that they would prefer to receive all available screenings on the same day if possible.

Breast Cancer Screening

Nearly all (98%) of the 1,100 women aged between 42 and 64 years reported having received a mammogram. These women were asked a specific subset of questions related to breast cancer screening. Respondents were asked to state the recommended age at which women should begin receiving mammogram screenings. More than half (55%) provided the correct response (40 years old, per the U.S. Preventive Services Task Force guidelines).^3,4 About three-quarters of respondents (789) correctly responded annually to the question regarding how often women should receive mammograms.

The survey also sought to identify barriers that prevented women from obtaining necessary breast cancer screening. However, the majority surveyed (85%) noted that the question was not applicable because they typically scheduled screening appointments. Only a few (3%) reported factors such as either themselves or someone they know having had a negative experience, discomfort, pain, or concerns of a falsepositive result as reasons for not obtaining breast cancer screening. Of the 112 respondents to the open-ended question, 25% reported that their schedules prevented them from scheduling a mammogram in the past; 12% reported that an inconvenient clinic location, appointment time, or process prevented them from receiving a screening; and 13% reported forgetting to schedule the screening (Table 2).

fed03403050s_t2.png

Cervical Cancer Screening

Female respondents aged between 21 and 64 years (n = 2,432) were asked about the recommended age at which women should begin receiving cervical cancer screening. Only 1% of respondents provided the correct response (that screening begins at 21 years of age per the U.S. Preventive Services Task Force Report guidelines), while 88% provided an incorrect response, and 11% were unsure or did not provide any response.⁵ Among all respondents, 98% reported having had a cervical cancer screening.

Respondents were asked how frequently women should have a Papanicolaou (Pap) test. Responses such as “2 to 3 years,” “2 years,” or “every other year” were labeled as correct, whereas responses such as “every 6 months” or “greater than 3 years” were labeled as incorrect. Just 12% of respondents provided a correct response, whereas 86% answered incorrectly, and 2% did not answer or did not know. Of those who answered incorrectly, the most common response was “annually” or “every year,” with no notable differences according to race, age, or beneficiary category.

To better understand barriers to screening, respondents were asked to identify reasons they might not have sought cervical cancer screening. The majority (84%) reported that they typically scheduled appointments and that the question was not applicable. However, among 228 respondents who provided an open-ended response and who had not previously undergone a hysterectomy, 8% stated that they had received no reminder or that they lacked sufficient information to schedule the appointment, 21% forgot to schedule, 18% reported a scheduling conflict or difficulty in receiving care, and 13% noted that they did not believe in annual screening (Table 2).

Colorectal Cancer Screening

Eighty-seven percent of eligible respondents (n = 1,734) reported having ever had a sigmoidoscopy and/or colonoscopy. Respondents were asked for their understanding of the recommended age for men and women to begin CRC screening.6 Nearly three-quarters of respondents provided a correct response (n = 1,225), compared with 23% of respondents (n = 407) who answered incorrectly and 6% (n = 102) who did not provide a response or stated they did not know. Correct responses were numerically higher among white respondents (73%) compared with black (62%) and other (62%) respondents as well as among persons aged < 60 years (73%) vs those aged > 60 years (67%).

Respondents aged between 51 and 64 years were asked how often the average person should receive colon cancer screenings. The most common response was that screening should occur every 5 years (33%) followed by every 10 years (26%). This aligns with the U.S. Preventive Services Task Force’s recommendations for flexible sigmoidoscopy every 5 years or colonoscopy every 10 years.

Eligible respondents were asked to identify reasons they did not seek CRC screening. Eighty-six percent of respondents indicated that they typically scheduled CRC screening and that the question was not applicable. Among respondents who provided an open-ended response, 26% cited feeling uncomfortable with the procedure, 15% cited forgetting to schedule a screening, 15% noted a lack of information on screening, and 11% reported no need for screening (Table 2). Among the 1,734 respondents, 80% reported that they would prefer a fecal occult blood test (FOBT) over either a colonoscopy or a sigmoidoscopy. Only 51% reported that their PCM had previously discussed the different types of CRC screenings at some point.

Discussion

The purpose of this large, representative survey was to obtain information on beneficiaries’ knowledge, perceived barriers, and beliefs regarding breast, cervical, and colorectal cancer screenings to identify factors contributing to low completion rates. As far as is known, this is the first study to address these questions in a TRICARE population. Overall, the findings suggest that beneficiaries consider cancer screening important, largely relying on their PCM or their research to better understand how and when to obtain such screenings. The majority received 1 or more screenings prior to the survey, but there were some common knowledge gaps about how to schedule screening appointments, relevant TRICARE medical benefits, and the current recommendations regarding screening timing and frequency. A commonly reported issue across all surveyed groups was inconvenient screening times.

More than half (55%) of respondents correctly noted that breast cancer screening begins at age 40 years (based on recommendations at the time the survey was conducted), and 72% understood when screening should occur. Despite access to care, inconvenient schedules and testing locations were considered the biggest barriers to regularly obtaining a mammogram. There are few studies on knowledge of breast cancer screening in an insured population available for comparison.^7-10 One study of medically insured black and non-Hispanic women aged 43 to 49 years showed that lack of reminders or knowledge about the need for mammograms, cost, being too busy, and forgetting to schedule appointments were all factors associated with nonadherence to repeat mammography examinations.⁸ In an integrative review published in 2000, authors cited that among 8 of 13 relevant studies, the major barrier to receiving a recommended mammogram was lack of physician recommendation.⁷

For cervical cancer screening, few respondents (1%) correctly identified the age for initiation of screening, and just 12% correctly identified the frequency of screening. These findings are consistent with those of other studies, suggesting a general misunderstanding
about Pap tests in the U.S. and among low-income women.^11,12 Reported barriers to screening were uncommon but included scheduling conflicts and lack of reminders or information and were consistent with barriers cited in prior studies.^13,14 A few respondents (13%) noted that they did not believe in annual screening, which is similar to the findings of Decker and colleagues who cited lack of knowledge about the test and belief that screening is of no benefit as reasons for failure to get a recommended Pap test.¹³ These findings suggest a need to improve patientprovider communication and to provide more patient educational materials about the importance of cervical cancer screening.

A large proportion (71%) gave the correct response regarding the appropriate age to initiate CRC screening. Discomfort with the procedure, belief that the screening is unnecessary, or lack of physician’s recommendation were noted barriers to CRC screening. These findings are similar to those reported elsewhere in non-TRICARE populations.^15-20 Two focus groups included participants with little knowledge about CRC screening, such as risk factors and symptoms, and expressed fear and embarrassment about CRC and screening. Few of the focus group participants were aware of the available options for screening, and some were confused about the purpose and benefits of the various screening modalities.¹⁶

A Health Information National Trends survey reported that 24% participants had not received a colonoscopy or a sigmoidoscopy because their PCM did not order it or say that it was necessary.¹⁵ The reported perceived barriers included fear of an adverse finding, injury to the colon from screening, and embarrassment. A study performed in 1,901 Medicare-insured individuals with no history of CRC cited lack of knowledge/awareness and no physician order as the most common reasons for not undergoing CRC screening.¹⁸

Strengths and Limitations

A major strength of the current survey is the 56% completion rate, which far exceeds other survey participation rates that were as low as 9%.²¹ A second strength is the scope of the survey to capture information on not 1 but 3 different cancer screening practices in a unique population who receive preventive screenings at low to no cost.

There are a few study limitations. The majority of respondents identified as white (80%), which does not fully align with the racial distribution of the TRICARE Prime population in the West Region, which is about 68% white. This higher proportion of white respondents may affect the ability to generalize findings to other populations. However, given the open access to care, race should not be a major factor contributing to screening decisions. Another potential limitation to the generalizability of the study is that the age of the respondents was capped at 64 years. Considering that some of the reported barriers to screening were “too busy” or “scheduling conflict,” a study population that included respondents aged ≥ 65 years (who might be more likely to be retired) might report lower rates of these schedule-related barriers.

A third limitation is that most questions about prior screenings pertained to any time in the past, and, therefore, limited the ability to identify current factors leading to lower screening rates. Last, the survey was developed prior to the 2012 changes in cervical and breast cancer screening recommendations and was therefore scored based on prior recommendations. Given that the goal was to assess knowledge and barriers, results are not expected to differ greatly if they are scored using the newer guidelines.

Conclusion

Findings from this cross-sectional survey indicate high levels of knowledge among TRICARE West Region beneficiaries regarding when and how often screening for breast cancer, cervical cancer, and CRC should occur. To encourage TRICARE beneficiaries to seek and obtain recommended and covered cancer screenings, further efforts are needed, including more education about the importance of screening and how to obtain screening. The survey results suggest that TRICARE Prime beneficiaries view cancer screening as important for overall health but they require (and also may desire) more frequent scheduling reminders, education, and more options for scheduling. Newer modalities for communicating with beneficiaries, such as automated telephone appointment reminders, reminder texts, online appointment scheduling, educational blogs, podcasts on cancer screening, extended appointment hours, or unconventional strategies to bundle screening services, are tools that could be used by providers to achieve greater compliance with cancer screening recommendations.

The National Defense Appropriations Act for fiscal year 2009, Subtitle B, waived copayments for preventive cancer screening services for all TRICARE beneficiaries, excluding Medicare-eligible beneficiaries.¹ These preventive services include screening for colorectal cancer (CRC), breast cancer, and cervical cancer based on current guidelines (eAppendix1).

Despite having unrestricted access to these cancer screenings, TRICARE Prime beneficiaries report overall screening completion rates that are below the national commercial benchmarks established by the Healthcare Effectiveness Data and Information Set (HEDIS) for all 3 cancer types.² Specifically, among TRICARE Prime beneficiaries enrolled in the western region of the U.S. in October 2013, the reported breast cancer screening rate was 61.6% (43,138/69,976) for women aged 42 to 69 years, which is well below the HEDIS 75th percentile of 76%. Similarly, the reported rate of cervical cancer screening among women aged 24 to 64 years was 68.3% (63,523/92,946), well below the HEDIS 75th percentile of 79%. Last, the reported rate of CRC screening among male and female TRICARE Prime members aged 51 to 75 years was 61.6% (52,860/85,827), also below the 2013 HEDIS 75th percentile of 63% based on internal review of TRICARE data used for HEDIS reporting.

Given the reported low screening rates, the Defense Health Agency (DHA) performed a cross-sectional survey to assess TRICARE Prime West region beneficiaries’ knowledge and understanding of preventive health screening, specifically for breast cancer, cervical cancer, and CRC, and to identify any potential barriers to access for these screenings.

Methods

A mostly closed-ended, 42-item telephone survey was designed and conducted (eAppendix2)

All women participating in the survey, regardless of age, were asked questions regarding cervical cancer screening. Women aged ≥ 42 years additionally were asked a second set of survey questions specific to breast cancer screening, and women aged between 51 and 64 years were asked a third set of questions related to CRC screening. The ages selected were 1 to 2 years after the recommended age for the respective screening to ensure adequate follow-up time for the member to obtain the screening. Men included in the survey were asked questions related only to CRC screening.

The target survey sample was 3,500 beneficiaries, separated into the following 4 strata: women aged 21 to 64 years of age enrolled in the direct care system (n = 1,250); women aged 21 to 64 years enrolled in the purchased (commercial) care network (n = 1,250); men aged 51 to 64 years enrolled in the direct care system (n = 500); and men aged 51 to 64 years enrolled in the purchased care network (n = 500). The random sample was drawn from an overall population of about 35,000 members. Sampling was performed without replacement until the target number of surveys was achieved. Survey completion was defined as the respondent having reached the end of the survey questionnaire but not necessarily having answered every question.

Data Elements

The preventive health survey collected information on beneficiaries’ knowledge of and satisfaction with their PCM, the primary location where they sought health care in the previous 12 months, preference for scheduling cancer screening tests, and general knowledge about the frequency and type of screening for breast, cervical, and colorectal cancers. Responses were scored based on guidelines effective as of 2009. In addition, the survey collected information on the beneficiary’s overall health status, current age, highest level of education achieved, current employment status, place of residence (on or off a military installation), race, and whether the beneficiary carried other health insurance aside from TRICARE.

Survey Mode and Fielding

A sampling population of eligible beneficiaries was created from a database of all TRICARE Prime beneficiaries. An automated system was used to randomly draw potential participants from the sample. Survey interviewers were given the beneficiary’s name and telephone number but no other identifiable information. Phone numbers from the sample were dialed up to 6 times before the number was classified as a “no answer.” Interviewers read to each beneficiary a statement describing the survey and participation risk and benefits and explained that participation was voluntary and the participant could end the survey at any time without penalty or prejudice. The survey commenced only after verbal consent was obtained.

Sample Weighting and Statistical Analysis

Each survey record was weighted to control for potential bias associated with unequal rates of noncoverage and nonresponse in the sampled population. A design weight was calculated as the ratio of the frame size and the sample size in each stratum. For each stratum, an adjusted response rate (RR) was calculated as the number of completed surveys divided by the number of eligible respondents. Since all respondents were eligible, the RR was not adjusted. The ratio of the design weight to the adjusted RR was calculated and assigned to each survey.

Frequency distributions and descriptive statistics were calculated for all close-ended survey items. Open-ended survey items were summarized and assessed qualitatively. When appropriate, open-ended responses were categorized and included in descriptive analyses. No formal statistical testing was performed.

Results

A total of 6,563 beneficiaries were contacted, and 3,688 agreed to participate (56%), resulting in 3,500 TRICARE beneficiaries completing the survey (95% completion rate), of whom 71% (2,500) were female. The overall cooperation rates were similar across the 4 strata. Interviews ceased once 3,500 surveys were completed. The largest distribution of respondents was aged between 55 and 64 years (37%) (Table 1). Respondents aged 21 to 24 years comprised the smallest percentage of the sample (7%). Nearly a third of respondents were dependents of ADSMs (30%), another 30% were retirees, and most respondents self-identified as white (Table 1).

Barriers to Screening

A series of survey questions was asked about specific barriers to cancer screening, including the convenience of appointment times for the respondent’s last cancer screening. The majority (69%, 2,415 of 3,500) responded that the appointment times were convenient. Among those who stated that times were not convenient and those who had not scheduled an examination, 66% responded that they did not know or were not sure how to schedule a cancer screening test.

Screening Preferences

Less than half of survey respondents (48%) reported that they received screening guideline information from their physician or provider; 24% reported that they performed their own research. Only 9% reported that they learned about the guidelines through TRICARE materials, and 7% of respondents indicated that media, family, or friends were their source of screening information.

The survey respondents who indicated that they had not scheduled a screening examination were asked when (time of day) they preferred to have a screening. Less than half (47%) reported that varying available appointment times would not affect their ability to obtain screening. One-quarter preferred times for screening during working hours, 20% preferred times after working hours, 6% preferred times before working hours, and 2% responded that they were unsure or did not know. The majority (89%) reported that they would prefer to receive all available screenings on the same day if possible.

Breast Cancer Screening

Nearly all (98%) of the 1,100 women aged between 42 and 64 years reported having received a mammogram. These women were asked a specific subset of questions related to breast cancer screening. Respondents were asked to state the recommended age at which women should begin receiving mammogram screenings. More than half (55%) provided the correct response (40 years old, per the U.S. Preventive Services Task Force guidelines).^3,4 About three-quarters of respondents (789) correctly responded annually to the question regarding how often women should receive mammograms.

The survey also sought to identify barriers that prevented women from obtaining necessary breast cancer screening. However, the majority surveyed (85%) noted that the question was not applicable because they typically scheduled screening appointments. Only a few (3%) reported factors such as either themselves or someone they know having had a negative experience, discomfort, pain, or concerns of a falsepositive result as reasons for not obtaining breast cancer screening. Of the 112 respondents to the open-ended question, 25% reported that their schedules prevented them from scheduling a mammogram in the past; 12% reported that an inconvenient clinic location, appointment time, or process prevented them from receiving a screening; and 13% reported forgetting to schedule the screening (Table 2).

fed03403050s_t2.png

Cervical Cancer Screening

Female respondents aged between 21 and 64 years (n = 2,432) were asked about the recommended age at which women should begin receiving cervical cancer screening. Only 1% of respondents provided the correct response (that screening begins at 21 years of age per the U.S. Preventive Services Task Force Report guidelines), while 88% provided an incorrect response, and 11% were unsure or did not provide any response.⁵ Among all respondents, 98% reported having had a cervical cancer screening.

Respondents were asked how frequently women should have a Papanicolaou (Pap) test. Responses such as “2 to 3 years,” “2 years,” or “every other year” were labeled as correct, whereas responses such as “every 6 months” or “greater than 3 years” were labeled as incorrect. Just 12% of respondents provided a correct response, whereas 86% answered incorrectly, and 2% did not answer or did not know. Of those who answered incorrectly, the most common response was “annually” or “every year,” with no notable differences according to race, age, or beneficiary category.

To better understand barriers to screening, respondents were asked to identify reasons they might not have sought cervical cancer screening. The majority (84%) reported that they typically scheduled appointments and that the question was not applicable. However, among 228 respondents who provided an open-ended response and who had not previously undergone a hysterectomy, 8% stated that they had received no reminder or that they lacked sufficient information to schedule the appointment, 21% forgot to schedule, 18% reported a scheduling conflict or difficulty in receiving care, and 13% noted that they did not believe in annual screening (Table 2).

Colorectal Cancer Screening

Eighty-seven percent of eligible respondents (n = 1,734) reported having ever had a sigmoidoscopy and/or colonoscopy. Respondents were asked for their understanding of the recommended age for men and women to begin CRC screening.6 Nearly three-quarters of respondents provided a correct response (n = 1,225), compared with 23% of respondents (n = 407) who answered incorrectly and 6% (n = 102) who did not provide a response or stated they did not know. Correct responses were numerically higher among white respondents (73%) compared with black (62%) and other (62%) respondents as well as among persons aged < 60 years (73%) vs those aged > 60 years (67%).

Respondents aged between 51 and 64 years were asked how often the average person should receive colon cancer screenings. The most common response was that screening should occur every 5 years (33%) followed by every 10 years (26%). This aligns with the U.S. Preventive Services Task Force’s recommendations for flexible sigmoidoscopy every 5 years or colonoscopy every 10 years.

Eligible respondents were asked to identify reasons they did not seek CRC screening. Eighty-six percent of respondents indicated that they typically scheduled CRC screening and that the question was not applicable. Among respondents who provided an open-ended response, 26% cited feeling uncomfortable with the procedure, 15% cited forgetting to schedule a screening, 15% noted a lack of information on screening, and 11% reported no need for screening (Table 2). Among the 1,734 respondents, 80% reported that they would prefer a fecal occult blood test (FOBT) over either a colonoscopy or a sigmoidoscopy. Only 51% reported that their PCM had previously discussed the different types of CRC screenings at some point.

Discussion

The purpose of this large, representative survey was to obtain information on beneficiaries’ knowledge, perceived barriers, and beliefs regarding breast, cervical, and colorectal cancer screenings to identify factors contributing to low completion rates. As far as is known, this is the first study to address these questions in a TRICARE population. Overall, the findings suggest that beneficiaries consider cancer screening important, largely relying on their PCM or their research to better understand how and when to obtain such screenings. The majority received 1 or more screenings prior to the survey, but there were some common knowledge gaps about how to schedule screening appointments, relevant TRICARE medical benefits, and the current recommendations regarding screening timing and frequency. A commonly reported issue across all surveyed groups was inconvenient screening times.

More than half (55%) of respondents correctly noted that breast cancer screening begins at age 40 years (based on recommendations at the time the survey was conducted), and 72% understood when screening should occur. Despite access to care, inconvenient schedules and testing locations were considered the biggest barriers to regularly obtaining a mammogram. There are few studies on knowledge of breast cancer screening in an insured population available for comparison.^7-10 One study of medically insured black and non-Hispanic women aged 43 to 49 years showed that lack of reminders or knowledge about the need for mammograms, cost, being too busy, and forgetting to schedule appointments were all factors associated with nonadherence to repeat mammography examinations.⁸ In an integrative review published in 2000, authors cited that among 8 of 13 relevant studies, the major barrier to receiving a recommended mammogram was lack of physician recommendation.⁷

For cervical cancer screening, few respondents (1%) correctly identified the age for initiation of screening, and just 12% correctly identified the frequency of screening. These findings are consistent with those of other studies, suggesting a general misunderstanding
about Pap tests in the U.S. and among low-income women.^11,12 Reported barriers to screening were uncommon but included scheduling conflicts and lack of reminders or information and were consistent with barriers cited in prior studies.^13,14 A few respondents (13%) noted that they did not believe in annual screening, which is similar to the findings of Decker and colleagues who cited lack of knowledge about the test and belief that screening is of no benefit as reasons for failure to get a recommended Pap test.¹³ These findings suggest a need to improve patientprovider communication and to provide more patient educational materials about the importance of cervical cancer screening.

A large proportion (71%) gave the correct response regarding the appropriate age to initiate CRC screening. Discomfort with the procedure, belief that the screening is unnecessary, or lack of physician’s recommendation were noted barriers to CRC screening. These findings are similar to those reported elsewhere in non-TRICARE populations.^15-20 Two focus groups included participants with little knowledge about CRC screening, such as risk factors and symptoms, and expressed fear and embarrassment about CRC and screening. Few of the focus group participants were aware of the available options for screening, and some were confused about the purpose and benefits of the various screening modalities.¹⁶

A Health Information National Trends survey reported that 24% participants had not received a colonoscopy or a sigmoidoscopy because their PCM did not order it or say that it was necessary.¹⁵ The reported perceived barriers included fear of an adverse finding, injury to the colon from screening, and embarrassment. A study performed in 1,901 Medicare-insured individuals with no history of CRC cited lack of knowledge/awareness and no physician order as the most common reasons for not undergoing CRC screening.¹⁸

Strengths and Limitations

A major strength of the current survey is the 56% completion rate, which far exceeds other survey participation rates that were as low as 9%.²¹ A second strength is the scope of the survey to capture information on not 1 but 3 different cancer screening practices in a unique population who receive preventive screenings at low to no cost.

There are a few study limitations. The majority of respondents identified as white (80%), which does not fully align with the racial distribution of the TRICARE Prime population in the West Region, which is about 68% white. This higher proportion of white respondents may affect the ability to generalize findings to other populations. However, given the open access to care, race should not be a major factor contributing to screening decisions. Another potential limitation to the generalizability of the study is that the age of the respondents was capped at 64 years. Considering that some of the reported barriers to screening were “too busy” or “scheduling conflict,” a study population that included respondents aged ≥ 65 years (who might be more likely to be retired) might report lower rates of these schedule-related barriers.

A third limitation is that most questions about prior screenings pertained to any time in the past, and, therefore, limited the ability to identify current factors leading to lower screening rates. Last, the survey was developed prior to the 2012 changes in cervical and breast cancer screening recommendations and was therefore scored based on prior recommendations. Given that the goal was to assess knowledge and barriers, results are not expected to differ greatly if they are scored using the newer guidelines.

These findings are similar to those reported elsewhere in non-TRICARE populations.^15-20 Two focus groups included participants with little knowledge about CRC screening, such as risk factors and symptoms, and expressed fear and embarrassment about CRC and screening. Few of the focus group participants were aware of the available options for screening, and some were confused about the purpose and benefits of the various screening modalities.¹⁶

A Health Information National Trends survey reported that 24% participants had not received a colonoscopy or a sigmoidoscopy because their PCM did not order it or say that it was necessary.¹⁵ The reported perceived barriers included fear of an adverse finding, injury to the colon from screening, and embarrassment. A study performed in 1,901 Medicare-insured individuals with no history of CRC cited lack of knowledge/awareness and no physician order as the most common reasons for not undergoing CRC screening.¹⁸

Strengths and Limitations

A major strength of the current survey is the 56% completion rate, which far exceeds other survey participation rates that were as low as 9%.²¹ A second strength is the scope of the survey to capture information on not 1 but 3 different cancer screening practices in a unique population who receive preventive screenings at low to no cost.

There are a few study limitations. The majority of respondents identified as white (80%), which does not fully align with the racial distribution of the TRICARE Prime population in the West Region, which is about 68% white. This higher proportion of white respondents may affect the ability to generalize findings to other populations. However, given the open access to care, race should not be a major factor contributing to screening decisions. Another potential limitation to the generalizability of the study is that the age of the respondents was capped at 64 years. Considering that some of the reported barriers to screening were “too busy” or “scheduling conflict,” a study population that included respondents aged ≥ 65 years (who might be more likely to be retired) might report lower rates of these schedule-related barriers.

A third limitation is that most questions about prior screenings pertained to any time in the past, and, therefore, limited the ability to identify current factors leading to lower screening rates. Last, the survey was developed prior to the 2012 changes in cervical and breast cancer screening recommendations and was therefore scored based on prior recommendations. Given that the goal was to assess knowledge and barriers, results are not expected to differ greatly if they are scored using the newer guidelines.

Conclusion

Findings from this cross-sectional survey indicate high levels of knowledge among TRICARE West Region beneficiaries regarding when and how often screening for breast cancer, cervical cancer, and CRC should occur. To encourage TRICARE beneficiaries to seek and obtain recommended and covered cancer screenings, further efforts are needed, including more education about the importance of screening and how to obtain screening. The survey results suggest that TRICARE Prime beneficiaries view cancer screening as important for overall health but they require (and also may desire) more frequent scheduling reminders, education, and more options for scheduling. Newer modalities for communicating with beneficiaries, such as automated telephone appointment reminders, reminder texts, online appointment scheduling, educational blogs, podcasts on cancer screening, extended appointment hours, or unconventional strategies to bundle screening services, are tools that could be used by providers to achieve greater compliance with cancer screening recommendations.
