Highlights

Palliative care has been shown to improve quality of life, receipt of goal-concordant care, end-of-life decision-making, and improvement in pain and symptoms in individuals with serious illness. However, palliative and end-of-life care remain underutilized in racial and ethnic minorities.¹ Health disparities such as access, quality of care, and health outcomes among minority groups exist in delivery and receipt of care within the health care system, and this includes the care of individuals with serious illness and at the end of life.¹

Racial and ethnic minorities are less likely to receive goal-concordant care, participate in advance care planning, and have access to palliative care or hospice.^2-4 They are more likely to die in a hospital, have inadequate pain and symptom management, and experience poor provider-patient communication.^5-7 Other contributing factors include lack of knowledge of hospice and palliative care services, mistrust of the health care system, spiritual and religious beliefs, provider bias, and cultural beliefs.¹

Despite these disparities, interventions have had limited success,⁸ and there are gaps in content, methods, and inclusion of racial and ethnic groups within palliative care research.⁷

Efforts to improve health equity for people with serious illness have been identified as an “urgent call to action.”¹

A few recommended actionable items include delivering culturally competent care by ensuring availability of culturally and linguistically appropriate materials and information, education, and training for providers, and practicing cultural humility; contributing to workforce diversity by hiring and training diverse staff; and partnering with community organizations to build trust and to facilitate dissemination of culturally and linguistically appropriate information to providers in caring for their diverse patient populations.^1,9

One of the first steps identified is to recognize that there is a problem and prioritize efforts to understand its “multifaceted nature.”¹⁰ This should occur on multiple levels including the individual (patient and caregiver), interpersonal (health care team), organization, and policy levels,¹⁰ and be done through clinical, research, and educational platforms.

At the interpersonal level, we as the health care team can start by reflecting, acknowledging biases, seeking educational and training opportunities on cross-cultural interactions, learning about cultural and spiritual beliefs, and developing skills in culturally and linguistically appropriate communication regarding goals of care and advance care planning.^1,10

For those seeking resources, organizations such as the Center to Advance Palliative Care’s Project Equity and the American Academy of Hospice and Palliative Medicine have ongoing efforts to educate and train physicians and health care professionals to improve and understand health equity in palliative care by providing resource portals, toolkits, training, and general information.

It is imperative to move forward in actionable ways to address not only racial and ethnic disparities, but advance equity in serious illness care for health care organizations, providers, and policymakers.¹

Every 4 years, an interprofessional panel of experts from the American Geriatrics Society provides updated guidelines on safe prescribing of medications in older adults, known as the Beers Criteria. A 2023 update was released in May 2023 after panel review of more 1,500 clinical trials and research studies published since the last update.

Anticoagulants

Notable changes to the 2023 guidelines include updated recommendations for anticoagulation. Warfarin should be avoided as initial therapy for venous thromboembolism or nonvalvular atrial fibrillation unless there are contraindications to direct oral anticoagulants (DOACs) or other substantial barriers to use.

Wang_Mengru_WASH_web.jpg

Rivaroxaban should also be avoided, and dabigatran used with caution in favor of apixaban, which is felt to have a better safety profile in older adults. Rivaroxaban may be considered if once daily dosing is deemed to be more clinically appropriate. Financial barriers regarding drug coverage and formulary options were acknowledged as a significant barrier to equitable access to preferred direct oral anticoagulants in older adults.
 

Diabetes medication

Regarding diabetes management, short-acting sulfonylureas should be avoided in addition to long-acting sulfonylureas, because of the increased risk of hypoglycemia, and cardiovascular and all-cause mortality in older adults. Sodium-glucose cotransporter 2 inhibitors as an entire class are recommended to be used with caution, as older adults are at higher risk of euglycemic ketoacidosis and urogenital infections, particularly in women in the first month of initiating treatment.

Like DOACs, the panel acknowledged that financial considerations may lead to limited options for oral diabetic treatment. In circumstances where a sulfonylurea is used, short-acting forms are preferred over long acting to reduce the risk of prolonged hypoglycemia.
 

Aspirin for primary prevention

Alongside the U.S. Preventive Services Task Force guideline update in 2022 regarding aspirin for primary prevention of cardiovascular disease and stroke, the Beer’s Criteria recommend against initiation of aspirin for primary prevention in older adults. Ticagrelor and prasugrel should be used with caution because of the increased risk of major bleeding in older adults over the age of 75, compared with clopidogrel. If prasugrel is used, a lower dose of 5 mg is recommended, in line with guidelines by the American College of Cardiology and American Heart Association.

Pain medication

For pain management, the Beer’s Criteria updated recommendations to avoid NSAIDs, particularly when used in combination with steroids or anticoagulants. The panel highlights that even short-term use of NSAIDs is high risk when used in combination with steroids or anticoagulants. If no other alternatives are possible, patients should be placed on a proton pump inhibitor or misoprostol while taking NSAIDs.

Baclofen should be avoided in older adults with renal insufficiency (estimated glomerular filtration rate < 60 mL/min per 1.73 m²) because of the increased risk of encephalopathy, and when used, should be given at the lowest effective dose with close monitoring for mental status changes.
 

Androgen and estrogen replacement therapy

For androgen replacement therapy, the panel notes that testosterone supplementation should be avoided because of cardiovascular risks unless there is confirmed hypogonadism. The panel revised their recommendation on the basis of emerging data that a history of prostate cancer is not an absolute contraindication for exogenous testosterone. A risk versus benefit discussion about exogenous testosterone should be had with a medical oncologist or urologist in those with a history of prostate cancer.

Regarding estrogen, systemic formulations should not be initiated in women over the age of 60 because of increased risk of cardiovascular events, venous thromboembolism, and dementia. In women with a history of breast cancer, vaginal estrogens are generally felt to be safe to use at low doses, such as less than 25 mcg twice weekly.

Food insecurity is linked to a more rapid decline in executive function in older adults, a new study shows.

The findings were reported just weeks after a pandemic-era expansion in Supplemental Nutrition Assistance Program benefits ended, leading to less food assistance for about 5 million people over age 60 who participate in the program.

“Even though we found only a very small association between food insecurity and executive function, it’s still meaningful, because food insecurity is something we can prevent,” lead investigator Boeun Kim, PhD, MPH, RN, postdoctoral fellow at Johns Hopkins University School of Nursing, Baltimore, told this news organization.

The findings were published online  in JAMA Network Open.
 

National data

The number of Americans over 60 with food insecurity has more than doubled since 2007, with an estimated 5.2 million older adults reporting food insecurity in 2020.

Prior studies have linked malnutrition and food insecurity to a decline in cognitive function. Participating in food assistance programs such as SNAP is associated with slower memory decline in older adults.

However, to date, there has been no longitudinal study that has used data from a nationally representative sample of older Americans, which, Dr. Kim said, could limit generalizability of the findings.

To address that issue, investigators analyzed data from 3,037 participants in the National Health and Aging Trends Study, which includes community dwellers age 65 and older who receive Medicare.

Participants reported food insecurity over 7 years, from 2012 to 2019. Data on immediate memory, delayed memory, and executive function were from 2013 to 2020.

Food insecurity was defined as going without groceries due to limited ability or social support; a lack of hot meals related to functional limitation or no help; going without eating because of the inability to feed oneself or no available support; skipping meals due to insufficient food or money; or skipping meals for 5 days or more.

Immediate and delayed recall were assessed using a 10-item word-list memory task, and executive function was measured using a clock drawing test. Each year’s cognitive functions were linked to the prior year’s food insecurity data.

Over 7 years, 417 people, or 12.1%, experienced food insecurity at least once.

Those with food insecurity were more likely to be older, female, part of racial and ethnic minority groups, living alone, obese, and have a lower income and educational attainment, depressive symptoms, social isolation and disability, compared with those without food insecurity.

After adjusting for age, sex, race/ethnicity, educational level, income, marital status, body mass index, functional disability, social isolation, and other potential confounders, researchers found that food insecurity was associated with a more rapid decline in executive function (mean difference in annual change in executive function score, −0.04; 95% confidence interval, −0.09 to −0.003).

Food insecurity was not associated with baseline cognitive function scores or changes in immediate or delayed recall.

“Clinicians should be aware of the experience of food insecurity and the higher risk of cognitive decline so maybe they could do universal screening and refer people with food insecurity to programs that can help them access nutritious meals,” Dr. Kim said.
 

A sign of other problems?

Thomas Vidic, MD, said food insecurity often goes hand-in-hand with lack of medication adherence, lack of regular medical care, and a host of other issues. Dr. Vidic is a neurologist at the Elkhart Clinic, Ind., and an adjunct clinical professor of neurology at Indiana University.

“When a person has food insecurity, they likely have other problems, and they’re going to degenerate faster,” said Dr. Vidic, who was not part of the study. “This is one important component, and it’s one more way of getting a handle on people who are failing.”

Dr. Vidic, who has dealt with the issue of food insecurity with his own patients, said he suspects the self-report nature of the study may hide the true scale of the problem.

“I suspect the numbers might actually be higher,” he said, adding that the study fills a gap in the literature with a large, nationally representative sample.

“We’re looking for issues to help with the elderly as far as what can we do to keep dementia from progressing,” he said. “There are some things that make sense, but we’ve never had this kind of data before.”

The study was funded by the National Institute on Aging. Dr. Kim and Dr. Vidic have reported no relevant financial relationships.

“Clinicians should be aware of the experience of food insecurity and the higher risk of cognitive decline so maybe they could do universal screening and refer people with food insecurity to programs that can help them access nutritious meals,” Dr. Kim said.
 

A sign of other problems?

Thomas Vidic, MD, said food insecurity often goes hand-in-hand with lack of medication adherence, lack of regular medical care, and a host of other issues. Dr. Vidic is a neurologist at the Elkhart Clinic, Ind., and an adjunct clinical professor of neurology at Indiana University.

“When a person has food insecurity, they likely have other problems, and they’re going to degenerate faster,” said Dr. Vidic, who was not part of the study. “This is one important component, and it’s one more way of getting a handle on people who are failing.”

Dr. Vidic, who has dealt with the issue of food insecurity with his own patients, said he suspects the self-report nature of the study may hide the true scale of the problem.

“I suspect the numbers might actually be higher,” he said, adding that the study fills a gap in the literature with a large, nationally representative sample.

“We’re looking for issues to help with the elderly as far as what can we do to keep dementia from progressing,” he said. “There are some things that make sense, but we’ve never had this kind of data before.”

The study was funded by the National Institute on Aging. Dr. Kim and Dr. Vidic have reported no relevant financial relationships.

As we enter into this new year, it is a good time to review the past few years of living through a pandemic and the impact this has had on the field of palliative care.

The health care system as a whole as well as palliative care teams, have been challenged by the ongoing COVID-19 pandemic.

According to the World Health Organization, “Palliative care is an approach that improves the quality of life of patients and their families who are facing the problems associated with life-threatening illness, by the prevention and relief of suffering through early identification, assessment and treatment of pain and other problems whether physical, psychosocial and spiritual.”¹ They identify a global need and recognize palliative care as a “human right to health and as a standard of care particularly for individuals living with a serious illness.¹ However, the WHO goes further to recognize palliative care as an essential part of the response team during crises and health emergencies like a pandemic, noting that a response team without palliative care is “medically deficient and ethically indefensible.”²

The need for palliative care in the United States is projected to grow significantly in the next decades.³ However, there has been insufficient staffing to meet these needs, even prior to the pandemic.⁴ The demand for palliative care reached further unprecedented levels during the pandemic as palliative care teams played an integral role and were well situated to support not only patients and families with COVID-19,⁵ but to also support the well-being of health care teams caring for COVID-19 patients.^6,7

A recent survey that was conducted by the Center to Advance Palliative Care among palliative care leadership captured the experiences of leading their teams through a pandemic. Below are the results of this survey, which highlighted important issues and developments to palliative care during the pandemic.⁶
 

Increasing need for palliative care

One of the main findings from the national survey of palliative care leaders corroborated that the demands for palliative care have increased significantly from 2020 through the pandemic.

As with many areas in the health care system, the pandemic has emphasized the strain and short staffing of the palliative care teams. In the survey, 61% of leaders reported that palliative care consults significantly increased from prepandemic levels. But only 26% of these leaders said they had the staffing support to meet these needs.
 

Value of palliative care

The value of palliative care along with understanding of the role of palliative care has been better recognized during the pandemic and has been evidenced by the increase in palliative care referrals from clinical providers, compared with prepandemic levels. In addition, data collected showed that earlier palliative care consultations reduced length of hospital stay, decreased ICU admissions, and improved patient, family, and provider satisfaction.

Well-being of the workforce

The pandemic has been a tremendously stressful time for the health care workforce that has undoubtedly led to burnout. A nationwide study of physicians,⁸ found that 61% of physicians experienced burnout. This is a significant increase from prepandemic levels with impacts on mental health (that is, anxiety, depression). This study did not include palliative care specialists, but the CAPC survey indicates a similar feeling of burnout. Because of this, some palliative care specialists have left the field altogether, or are leaving leadership positions because of burnout and exhaustion from the pandemic. This was featured as a concern among palliative care leaders, where 93% reported concern for the emotional well-being of the palliative care team.

Telehealth

A permanent operational change that has been well-utilized and implemented across multiple health care settings has been providing palliative care through telehealth. Prior to the pandemic, the baseline use of telehealth was less than 5% with the use now greater than 75% – a modality that is favored by both patients and clinicians. This has offered a broader scope of practice, reaching individuals who may have no other means, have limitations to accessing palliative care, or were in circumstances where patients required isolation during the pandemic. However, there are limitations to this platform, including in equity of access to devices and ease of use for those with limited exposure to technology.⁹

Barriers to implementation

Although the important role and value of palliative care has been well recognized, there have been barriers identified in a qualitative study of the integration of palliative care into COVID-19 action plans that are mentioned below.⁵

• Patients and families were identified as barriers to integration of palliative care if they were not open to palliative care referral, mainly because of misperceptions of palliative care as end-of-life care.
• Palliative care knowledge among providers was identified as another barrier to integration of palliative care. There are still misperceptions among providers that palliative care is end-of-life care and palliative care involvement is stigmatized as hastening death. In addition, some felt that COVID-19 was not a traditional “palliative diagnosis” thus were less likely to integrate palliative care into care plans.
• Lack of availability of a primary provider to conduct primary palliative care and lack of motivation “not to give up” were identified as other barriers. On the other hand, palliative care provider availability and accessibility to care teams affected the integration into COVID-19 care plans.
• COVID-19 itself was identified to be a barrier because of the uncertainty of illness trajectory and outcomes, which made it difficult for doctors to ascertain when to involve palliative care.
• Leadership and institution were important factors to consider in integration of palliative care into long-term care plans, which depended on leadership engagement and institutional culture.

Takeaways

The past few years have taught us a lot, but there is still much to learn. The COVID-19 pandemic has called attention to the challenges and barriers of health care delivery and has magnified the needs of the health care system including its infrastructure, preparedness, and staffing, including the field of palliative care. More work needs to be done, but leaders have taken steps to initiate national and international preparedness plans including the integration of palliative care, which has been identified as a vital role in any humanitarian crises.^10,11

This article discusses updates in geriatrics from studies published in 2022 to early 2023. The topics covered include vitamin D supplementation and incident fractures, the association of social isolation and dementia, and the release of lecanemab, the second disease-modifying therapy for mild Alzheimer dementia.

Vitamin D supplementation and incident fractures

Vitamin D supplementation is a commonly recommended intervention for bone health, but data to support its impact on reducing fracture risk has been variable.

Wang_Mengru_Washington_web.jpg

A study in the New England Journal of Medicine by LeBoff and colleagues has garnered much attention since its publication in July 2022.¹ In the ancillary study of the Vitamin D and Omega-3-Trial (VITAL), the authors examined the impact of vitamin D supplementation versus placebo on incident fractures. The study found that vitamin D supplementation, as compared with placebo, led to no significant difference in the incidence of total, nonvertebral, and hip fractures in midlife and older adults over the 5-year period of follow-up.

The generalizability of these findings has been raised as a concern as the study does not describe adults at higher risk for fracture. The authors of the study specified in their conclusion that vitamin D supplementation does not reduce fracture risk in “generally healthy midlife and older adults who were not selected for vitamin D deficiency, low bone mass or osteoporosis.”

With a mean participant age of 67 and exclusion of participants with a history of cardiovascular disease, stroke, cirrhosis and other serious illnesses, the study does not reflect the multimorbid older adult population that geriatricians typically care for. Furthermore, efficacy of vitamin D supplementation on fracture risk may be the most impactful in those with osteoporosis and with severe vitamin D deficiency (defined by vitamin D 25[OH]D level less than 12 ng/mL).

In post hoc analyses, there was no significant difference in fracture risk in these subgroups, however the authors acknowledged that the findings may be limited by the small percentage of participants with severe vitamin D deficiency (2.4%) and osteoporosis included in the study (5%).
 

Lecanemab for mild cognitive impairment and early Alzheimer’s dementia

On Jan. 6, 2023, the Food and Drug Administration approved lecanemab, the second-ever disease-modifying treatment for Alzheimer’s dementia following the approval of aducanumab in 2021. Lecanemab is a monoclonal antibody targeting larger amyloid-beta oligomers, which has been shown in vitro to have higher affinity for amyloid-beta, compared with aducanumab. FDA approval followed shortly after the publication of the CLARITY-AD trial, which investigated the effect of lecanemab versus placebo on cognitive decline and burden of amyloid in adults with mild cognitive impairment and mild Alzheimer’s dementia. Over an 18-month period, the study found that participants who received lecanemab, compared with placebo, had a significantly smaller decline in cognition and function, and reduction in amyloid burden on PET CT.²

The clinical significance of these findings, however, is unclear. As noted by an editorial published in the Lancet in 2022, the difference in Clinical Dementia Rating-Sum of Boxes (CDR-SB) scale between the treatment and placebo groups was 0.45. On an 18-point scale, prior research has noted that a minimal clinically significance difference of 0.98 is necessary in those with mild cognitive impairment and 1.63 in mild Alzheimer dementia.³

Additionally, the CLARITY-AD trial reported that lecanemab resulted in infusion reactions in 26.4% of participants and brain edema (an amyloid-related imaging abnormality referred to as ARIA-E) in 12.6% of participants. This finding highlights concerns for safety and the need for close monitoring, as well as ongoing implications of economic feasibility and equitable access for all those who qualify for treatment.²

Social isolation and dementia risk

There is growing awareness of the impact of social isolation on health outcomes, particularly among older adults. Prior research has reported that one in four older adults are considered socially isolated and that social isolation increases risk of premature death, dementia, depression, and cardiovascular disease.⁴

A study by Huang and colleagues is the first nationally representative cohort study examining the association between social isolation and incident dementia for older adults in community dwelling settings. A cohort of 5,022 older adults participating in the National Health and Aging Trends Study was followed from 2011 to 2020. When adjusting for demographic and health factors, including race, level of education, and number of chronic health conditions, socially isolated adults had a greater risk of developing dementia, compared with adults who were not socially isolated (hazard ratio, 1.27; 95% confidence interval, 1.08-1.49). Potential mechanisms to explain this association include the increased risk of cardiovascular disease and depression in older adults who are socially isolated, thereby increasing dementia risk.

Decreased cognitive activity/engagement and access to resources such as caregiving and health care may also be linked to the increased risk of dementia in socially isolated older adults.⁵

Another observational cohort study from the National Health and Aging Trends Study investigated whether access and use of technology can lower the risk of social isolation. The study found that older adults who used email or text messaging had a lower risk of social isolation than older adults who did not use technology (incidence rate ratio, 0.64; 95% CI, 0.51-0.80).⁶ These findings highlight the importance of addressing social isolation as an important modifiable health risk factor, and the need for providing equitable access to technology in vulnerable populations as health intervention.

The study found that vitamin D supplementation, as compared with placebo, led to no significant difference in the incidence of total, nonvertebral, and hip fractures in midlife and older adults over the 5-year period of follow-up.

The generalizability of these findings has been raised as a concern as the study does not describe adults at higher risk for fracture. The authors of the study specified in their conclusion that vitamin D supplementation does not reduce fracture risk in “generally healthy midlife and older adults who were not selected for vitamin D deficiency, low bone mass or osteoporosis.”

With a mean participant age of 67 and exclusion of participants with a history of cardiovascular disease, stroke, cirrhosis and other serious illnesses, the study does not reflect the multimorbid older adult population that geriatricians typically care for. Furthermore, efficacy of vitamin D supplementation on fracture risk may be the most impactful in those with osteoporosis and with severe vitamin D deficiency (defined by vitamin D 25[OH]D level less than 12 ng/mL).

In post hoc analyses, there was no significant difference in fracture risk in these subgroups, however the authors acknowledged that the findings may be limited by the small percentage of participants with severe vitamin D deficiency (2.4%) and osteoporosis included in the study (5%).
 

Lecanemab for mild cognitive impairment and early Alzheimer’s dementia

On Jan. 6, 2023, the Food and Drug Administration approved lecanemab, the second-ever disease-modifying treatment for Alzheimer’s dementia following the approval of aducanumab in 2021. Lecanemab is a monoclonal antibody targeting larger amyloid-beta oligomers, which has been shown in vitro to have higher affinity for amyloid-beta, compared with aducanumab. FDA approval followed shortly after the publication of the CLARITY-AD trial, which investigated the effect of lecanemab versus placebo on cognitive decline and burden of amyloid in adults with mild cognitive impairment and mild Alzheimer’s dementia. Over an 18-month period, the study found that participants who received lecanemab, compared with placebo, had a significantly smaller decline in cognition and function, and reduction in amyloid burden on PET CT.²

The clinical significance of these findings, however, is unclear. As noted by an editorial published in the Lancet in 2022, the difference in Clinical Dementia Rating-Sum of Boxes (CDR-SB) scale between the treatment and placebo groups was 0.45. On an 18-point scale, prior research has noted that a minimal clinically significance difference of 0.98 is necessary in those with mild cognitive impairment and 1.63 in mild Alzheimer dementia.³

Additionally, the CLARITY-AD trial reported that lecanemab resulted in infusion reactions in 26.4% of participants and brain edema (an amyloid-related imaging abnormality referred to as ARIA-E) in 12.6% of participants. This finding highlights concerns for safety and the need for close monitoring, as well as ongoing implications of economic feasibility and equitable access for all those who qualify for treatment.²

Social isolation and dementia risk

There is growing awareness of the impact of social isolation on health outcomes, particularly among older adults. Prior research has reported that one in four older adults are considered socially isolated and that social isolation increases risk of premature death, dementia, depression, and cardiovascular disease.⁴

A study by Huang and colleagues is the first nationally representative cohort study examining the association between social isolation and incident dementia for older adults in community dwelling settings. A cohort of 5,022 older adults participating in the National Health and Aging Trends Study was followed from 2011 to 2020. When adjusting for demographic and health factors, including race, level of education, and number of chronic health conditions, socially isolated adults had a greater risk of developing dementia, compared with adults who were not socially isolated (hazard ratio, 1.27; 95% confidence interval, 1.08-1.49). Potential mechanisms to explain this association include the increased risk of cardiovascular disease and depression in older adults who are socially isolated, thereby increasing dementia risk.

Decreased cognitive activity/engagement and access to resources such as caregiving and health care may also be linked to the increased risk of dementia in socially isolated older adults.⁵

Another observational cohort study from the National Health and Aging Trends Study investigated whether access and use of technology can lower the risk of social isolation. The study found that older adults who used email or text messaging had a lower risk of social isolation than older adults who did not use technology (incidence rate ratio, 0.64; 95% CI, 0.51-0.80).⁶ These findings highlight the importance of addressing social isolation as an important modifiable health risk factor, and the need for providing equitable access to technology in vulnerable populations as health intervention.

Vitamin D supplementation and incident fractures

Vitamin D supplementation is a commonly recommended intervention for bone health, but data to support its impact on reducing fracture risk has been variable.

Many changes in the evolution of the treatment of diabetes have occurred during this year and 2021. Randomized controlled trials have resulted in updated guidelines for the use of glucagonlike peptide-1 receptor agonists (GLP1RAs) and continuous glucose monitoring (CGM) technology. I am hoping my discussion about these major advances in this edition of Highlights will be helpful to those caring for patients with diabetes.

Tirzepatide

The first GLP1RA, exenatide, was released in April 2005. Since then, numerous daily and weekly drugs of this class have been developed. We’ve learned they are effective glucose lowering drugs, and the weekly agents dulaglutide and semaglutide have shown impressive weight reduction properties as well as cardiovascular benefits.

Hirsch_Irl_B_Seattle_21_web.jpg

Secondary outcomes have also shown renal benefits to these agents, and studies for primary renal efficacy are pending. Due to all of these properties, the GLP1RAs are recommended as the first injectable for the treatment of type 2 diabetes, prior to insulin initiation.¹

The next generation of these agents are a combination of a GLP1RA and a glucose-dependent insulinotropic polypeptide (GIP). Glucagonlike peptide-1 (GLP-1) stimulates insulin secretion, inhibits glucagon secretion, delays gastric emptying, and has central effects inducing satiety.

We now understand that GIP is the main incretin hormone in those without diabetes, causative of most of the incretin effects. But the insulin response after GIP secretion in type 2 diabetes is strongly reduced. It is now appreciated that this poor effect of GIP can be reduced when used in combination with a GLP1RA. This combination incretin, called by some a “twincretin,” is the basis for the drug tirzepatide which was approved by the Food and Drug Administration in May of 2022.

The data supporting this agent for both diabetes and obesity are impressive. For example, in a 40-week study with a baseline HbA1c of 8.0%, those randomized to tirzepatide at 5 mg, 10 mg, and 15 mg had HbA1c reductions of 1.87%, 1.89%, and 2.07% respectively.² Over 81% at all doses had HbA1c levels less than 6.5% at 40 weeks.

For the 5-mg, 10-mg, and 15-mg doses, weight change from baseline was 7.9%, 9.3%, and 11.0% respectively. Like older GLP1RAs, gastrointestinal side effects were the main problem. For the three doses, 3%, 5%, and 7%, respectively, had to stop the drug, compared with the 3% who stopped taking the placebo. In another study, tirzepatide was noninferior or superior at all three doses compared with semaglutide 1 mg weekly.³

In a population without diabetes, with 40% of patients having prediabetes, weight loss percentages for the three doses were 15.0%, 19.5%, and 20.9% respectively.⁴ Discontinuation percentages due to side effects were 4%-7%. The exciting part is we now have a drug that approaches weight loss from bariatric surgery. The cardiovascular and renal outcome trials are now underway, but the enthusiasm for this drug is clear from the data.

Like other GLP1RAs, the key is to start low and go slowly. It is recommended to start tirzepatide at 2.5 mg four times a week, then increase to 5 mg. Due to gastrointestinal side effects, some patients will do better at the lower dose before increasing. For those switching from another GLP1RA, there are no data to guide us but, in my practice, I start those patients at 5 mg weekly.
 

Continuous glucose monitoring

Data continue to accumulate that this form of glycemic self-monitoring is effective to reduce HbA1c levels and minimize hypoglycemia in both type 1 and type 2 diabetes. The most important change to the 2022 American Diabetes Association (ADA) standards of care is recognizing CGM as level A evidence for those receiving basal insulin without mealtime insulin.⁵ There are four CGMs on the market, but most of the market uses the Dexcom G6 or the Libre 2. Both of these devices will be updated within the next few months to newer generation sensors.

While there are similarities and differences between the two devices, by late 2022 and early 2023 changes to both will reduce the dissimilarities.

The next generation Libre (Libre 3) will be continuous, and “scanning” will no longer be required.  For those unable to get insurance to cover CGM, the Libre will continue to be more affordable than the Dexcom. Alerts will be present on both, but the Dexcom G7 will be approved for both the arm and the abdomen. The Dexcom also can communicate with several automated insulin delivery systems and data can be shared real-time with family members.

For clinicians just starting patients on this technology, my suggestion is to focus on one system so both the provider and staff can become familiar with it. It is key to review downloaded glucose metrics, in addition to the “ambulatory glucose profile,” a graphic overview of daily glycemia where patterns can be identified. It is also helpful to ask for assistance from endocrinologists who have experience with CGMs, in addition to the representatives of the companies.

COVID-19 and new-onset diabetes

From the beginning of the COVID 19 pandemic in 2020, it was clear that stress hyperglycemia and glucose dysregulation was an important observation for those infected. What was not known at the time is that for some, the hyperglycemia continued, and permanent diabetes ensued.

In one study of over 2.7 million U.S. veterans, men infected with COVID-19, but not women, were at a higher risk of new incident diabetes at 120 days after infection compared to no infection (odds ratio for men = 2.56).⁶

Another literature review using meta-analyses and cross-sectional studies concluded new-onset diabetes following COVID-19 infection can have a varied phenotype, with no risk factors, presenting from diabetic ketoacidosis to milder forms of diabetes.⁷

The current thought is that COVID-19 binds to the ACE2 and TMPRSS2 receptors which appear to be located on the beta-cells in the islet, resulting in insulin deficiency, in addition to the insulin resistance that seems to persist after the acute infection. Much more needs to be learned about this, but clinicians need to appreciate this appears to be a new form of diabetes and optimal treatments are not yet clear.

The Dexcom also can communicate with several automated insulin delivery systems and data can be shared real-time with family members.

For clinicians just starting patients on this technology, my suggestion is to focus on one system so both the provider and staff can become familiar with it. It is key to review downloaded glucose metrics, in addition to the “ambulatory glucose profile,” a graphic overview of daily glycemia where patterns can be identified. It is also helpful to ask for assistance from endocrinologists who have experience with CGMs, in addition to the representatives of the companies.

COVID-19 and new-onset diabetes

From the beginning of the COVID 19 pandemic in 2020, it was clear that stress hyperglycemia and glucose dysregulation was an important observation for those infected. What was not known at the time is that for some, the hyperglycemia continued, and permanent diabetes ensued.

In one study of over 2.7 million U.S. veterans, men infected with COVID-19, but not women, were at a higher risk of new incident diabetes at 120 days after infection compared to no infection (odds ratio for men = 2.56).⁶

Another literature review using meta-analyses and cross-sectional studies concluded new-onset diabetes following COVID-19 infection can have a varied phenotype, with no risk factors, presenting from diabetic ketoacidosis to milder forms of diabetes.⁷

The current thought is that COVID-19 binds to the ACE2 and TMPRSS2 receptors which appear to be located on the beta-cells in the islet, resulting in insulin deficiency, in addition to the insulin resistance that seems to persist after the acute infection. Much more needs to be learned about this, but clinicians need to appreciate this appears to be a new form of diabetes and optimal treatments are not yet clear.

There are still misperceptions of palliative medicine, including when to consider referral to a palliative care specialist.

The World Health Organization defines palliative care as “an approach that improves the quality of life of patients (adults and children) and their families who are facing problems associated with life-threatening illness. It prevents and relieves suffering through the early identification, correct assessment, and treatment of pain and other problems, whether physical, psychosocial or spiritual.”¹

The common misperception is that palliative care is only for those at end of life or only in the advanced stages of their illness. However, palliative care is ideally most helpful following individuals from diagnosis through their illness trajectory. Another misperception is that palliative care and hospice are the same thing. Though all hospice is palliative care, all palliative care is not hospice. Both palliative care and hospice provide care for individuals facing a serious illness and focus on the same philosophy of care, but palliative care can be initiated at any stage of illness, even if the goal is to pursue curative and life-prolonging therapies/interventions.

In contrast, hospice is considered for those who are at the end of life and are usually not pursuing life-prolonging therapies or interventions, instead focusing on comfort, symptom management, and optimization of quality of life.

Though there is a growing need for palliative care, there is a shortage of specialist palliative care providers. Much of the palliative care needs can be met by all providers who can offer basic symptom management, identification surrounding goals of care and discussions of advance care planning, and understanding of illness/prognosis and treatment options, which is called primary palliative care.² In fact, two-thirds of patients with a serious illness other than cancer prefer discussion of end-of-life care or advance care planning with their primary care providers.³

Referral to specialty palliative care should be considered when there are more complexities to symptom/pain management and goals of care/end of life, transition to hospice, or complex communication dynamics.⁴

Though specialty palliative care was shown to be more comprehensive, both primary palliative care and specialty palliative care have led to improvements in the quality of life in individuals living with serious illness.⁵ Early integration of palliative care into routine care has been shown to improve symptom burden, mood, quality of life, survival, and health care costs.⁶

Updates in alternative and complementary therapies to palliative care

There are several alternative and complementary therapies to palliative care, including cannabis and psychedelics. These therapies are becoming or may become a familiar part of medical therapies that are listed in a patient’s history as part of their medical regimen, especially as more states continue to legalize and/or decriminalize the use of these alternative therapies for recreational or medicinal use.

Both cannabis and psychedelics have a longstanding history of therapeutic and holistic use. Cannabis has been used to manage symptoms such as pain since the 16th and 17th century.⁷ In palliative care, more patients may turn to various forms of cannabis as a source of relief from symptoms and suffering as their focus shifts more to quality of life.

Even with the increasing popularity of the use of cannabis among seriously ill patients, there is still a lack of evidence of the benefits of medical cannabis use in palliative care, and there is a lack of standardization of type of cannabis used and state regulations regarding their use.⁷

A recent systematic review found that despite the reported positive treatment effects of cannabis in palliative care, the results of the studies were conflicting. This highlights the need for further high-quality research to determine whether cannabis products are an effective treatment in palliative care patients.⁸

One limitation to note is that the majority of the included studies focused on cannabis use in patients with cancer for cancer-related symptoms. Few studies included patients with other serious conditions.
 

Psychedelics

There is evidence that psychedelic assisted therapy (PAT) is a safe and effective treatment for individuals with refractory depression, posttraumatic stress disorder, and substance use disorder.⁹ Plus, there have been ample studies providing support that PAT improves symptoms such as refractory anxiety/depression, demoralization, and existential distress in seriously ill patients, thus improving their quality of life and overall well-being.⁹

Nine U.S. cities and the State of Oregon have decriminalized or legalized the psychedelic psilocybin, based on the medical benefits patients have experienced evidenced from using it.¹⁰

In light of the increasing interest in PAT, Dr. Ira Byock provided the following points on what “all clinicians should know as they enter this uncharted territory”:

• Psychedelics have been around for a long time.
• Psychedelic-assisted therapies’ therapeutic effects are experiential.
• There are a variety of terms for specific categories of psychedelic compounds.
• Some palliative care teams are already caring for patients who undergo psychedelic experiences.
• Use of psychedelics should be well-observed by a skilled clinician with expertise.

I am hoping this provides a general refresher on palliative care and an overview of updates to alternative and complementary therapies for patients living with serious illness.⁹

The following highlights are a brief overview of guideline updates, drug approvals, and diagnostics relevant to geriatric medicine from June 2021 to April 2022, some of which were discussed at the American Geriatrics Society conference in May. I selected these topics as they were among the most discussed by my colleagues in geriatric medicine and inquired about by my primary care patients in geriatric medicine clinic. I hope that these updates provide primary care clinicians who care for older adults with more context and background information regarding new Alzheimer’s disease therapy to better answer patient inquiries, and to feel empowered to deprescribe aspirin and reframe the diagnostic criteria of chronic kidney disease (CKD).

Aspirin for primary prevention

It was welcome news in the geriatrics community when the United States Preventive Services Task Force updated their guidelines in April 2022 to recommend against the initiation of aspirin for primary prevention in adults aged 60 or older. This recommendation was based on studies that found that net benefits of CVD prevention in older adults are outweighed by risk of bleeding.¹

Wang_Mengru_Washington_web.jpg

The risk of bleeding increases with age and can occur in individuals without common risk factors for bleeding, such as prior gastrointestinal bleeding, peptic ulcer disease, concurrent NSAID use, or corticosteroid use.

While it may be easier to not initiate aspirin for primary prevention, deprescribing aspirin for patients who have been on aspirin long term for primary prevention presents more of a challenge. Modeling data from the USPTSF suggest stopping aspirin at age 75 for those taking aspirin for primary prevention.²

Behavioral change, particularly for patients who have been on aspirin for decades, can be difficult. A 2021 study by Green et al. found that language that resonates the most with older adults when deprescribing emphasized the side effects rather than statements such as “this will not help you” or “do not need anymore.”3
 

Aducanumab for mild cognitive impairment and mild Alzheimer’s dementia

One of the most discussed topics this past year is the Food and Drug Administration approval of aducanumab (brand name Aduhelm) in June 2021. Aducanumab is the first approved disease-modifying therapy for Alzheimer’s disease and the first drug approved for the treatment of Alzheimer’s disease since 2003. Aducanumab is an antiamyloid monoclonal antibody that was developed to reduce amyloid plaque in the brain, one of the features of Alzheimer’s disease pathology.

Uptake of aducanumab by dementia providers has been limited for several reasons. Firstly, the clinical significance of the drug remains in question. ENGAGE and EMERGE were the two main randomized clinical trials that studied the effect of aducanumab on amyloid burden and clinical stages of dementia over 18 months. While both studies demonstrated that aducanumab reduced amyloid burden based on neuroimaging and in cerebrospinal fluid, the ENGAGE trial found no difference in the stage of dementia. The EMERGE trial did note a small, statistically significant difference in stage of dementia, however the participants of the EMERGE trial had a faster rate of progression of dementia than the placebo participants in the ENGAGE trial, which could have contributed to the difference detected.⁴

Additionally, exclusion criteria for both trials call into question the generalizability of this study. Participants over age 85, with CKD, prior stroke, or transient ischemic attacks, or on anticoagulation were excluded. One of the drivers for the exclusion criteria is the increased risk of macro and microhemorrhages.

Thirty-five percent of research participants were incidentally noted to have brain edema, an abnormality called amyloid-related imaging abnormality or ARIA-E, that necessitated serial monitoring with brain MRIs. It is also important to highlight that inclusion of African American, Hispanic, and Latinx participants in these studies was less than 5%, despite a higher incidence of Alzheimer’s disease in these populations.⁵

Lastly, economic implications for the U.S. health care system with increased uptake of aducanumab could be enormous. Originally quoted at $56,000 yearly, Biogen, the maker of aducanumab, recently reduced annual costs to $28,200 per patient.

In April 2022, CMS released a statement that antiamyloid monoclonal antibodies and related services, including PET scans, would be covered under Medicare for those with mild cognitive impairment and mild Alzheimer’s dementia with confirmed presence of amyloid. A study by Mafi et al. estimated that aducanumab could cost Medicare between $7 billion and $37.4 billion annually based on lower and upper bound estimates of eligible Medicare beneficiaries.⁶
 

Overdiagnosis of CKD in older adults

The current diagnostic criteria of CKD, which is based on an estimated glomerular filtration rate (eGFR) of less than 60, has been up for debate, as glomerular filtration rate (GFR) physiologically decreases with age. Fixed thresholds can lead to underdiagnosis of CKD in younger adults and overdiagnosis of CKD in older adults. Age-adapted thresholds for the diagnosis of CKD have been proposed, with the suggestion of an eGFR threshold of 45mL/min/1.73 m² for adults aged 65 and older.⁷

The clinical implication of using an age-adapted eGFR threshold definition was investigated in a 2021 cohort study by Liu et al.⁸ In this study, outcomes of adults diagnosed with CKD using a fixed threshold versus age-adapted threshold were compared with a healthy cohort.

A fixed threshold led to a 60% higher incidence of CKD diagnosis. However, incidence of renal failure and all-cause mortality in older adults with an eGFR between 45-59 /min/1.73 m2 with normal or mild albuminuria was of similar magnitude to the healthy cohort at 5 years of follow-up.

These findings support the use of age-adapted thresholds for the diagnosis of CKD in older adults, as an earlier diagnosis of mild CKD does not equate to clinical benefits, but could lead to harms of unnecessary interventions and patient anxiety.

Aducanumab is the first approved disease-modifying therapy for Alzheimer’s disease and the first drug approved for the treatment of Alzheimer’s disease since 2003. Aducanumab is an antiamyloid monoclonal antibody that was developed to reduce amyloid plaque in the brain, one of the features of Alzheimer’s disease pathology.

Uptake of aducanumab by dementia providers has been limited for several reasons. Firstly, the clinical significance of the drug remains in question. ENGAGE and EMERGE were the two main randomized clinical trials that studied the effect of aducanumab on amyloid burden and clinical stages of dementia over 18 months. While both studies demonstrated that aducanumab reduced amyloid burden based on neuroimaging and in cerebrospinal fluid, the ENGAGE trial found no difference in the stage of dementia. The EMERGE trial did note a small, statistically significant difference in stage of dementia, however the participants of the EMERGE trial had a faster rate of progression of dementia than the placebo participants in the ENGAGE trial, which could have contributed to the difference detected.⁴

Additionally, exclusion criteria for both trials call into question the generalizability of this study. Participants over age 85, with CKD, prior stroke, or transient ischemic attacks, or on anticoagulation were excluded. One of the drivers for the exclusion criteria is the increased risk of macro and microhemorrhages.

Thirty-five percent of research participants were incidentally noted to have brain edema, an abnormality called amyloid-related imaging abnormality or ARIA-E, that necessitated serial monitoring with brain MRIs. It is also important to highlight that inclusion of African American, Hispanic, and Latinx participants in these studies was less than 5%, despite a higher incidence of Alzheimer’s disease in these populations.⁵

Lastly, economic implications for the U.S. health care system with increased uptake of aducanumab could be enormous. Originally quoted at $56,000 yearly, Biogen, the maker of aducanumab, recently reduced annual costs to $28,200 per patient.

In April 2022, CMS released a statement that antiamyloid monoclonal antibodies and related services, including PET scans, would be covered under Medicare for those with mild cognitive impairment and mild Alzheimer’s dementia with confirmed presence of amyloid. A study by Mafi et al. estimated that aducanumab could cost Medicare between $7 billion and $37.4 billion annually based on lower and upper bound estimates of eligible Medicare beneficiaries.⁶
 

Overdiagnosis of CKD in older adults

The current diagnostic criteria of CKD, which is based on an estimated glomerular filtration rate (eGFR) of less than 60, has been up for debate, as glomerular filtration rate (GFR) physiologically decreases with age. Fixed thresholds can lead to underdiagnosis of CKD in younger adults and overdiagnosis of CKD in older adults. Age-adapted thresholds for the diagnosis of CKD have been proposed, with the suggestion of an eGFR threshold of 45mL/min/1.73 m² for adults aged 65 and older.⁷

The clinical implication of using an age-adapted eGFR threshold definition was investigated in a 2021 cohort study by Liu et al.⁸ In this study, outcomes of adults diagnosed with CKD using a fixed threshold versus age-adapted threshold were compared with a healthy cohort.

A fixed threshold led to a 60% higher incidence of CKD diagnosis. However, incidence of renal failure and all-cause mortality in older adults with an eGFR between 45-59 /min/1.73 m2 with normal or mild albuminuria was of similar magnitude to the healthy cohort at 5 years of follow-up.

These findings support the use of age-adapted thresholds for the diagnosis of CKD in older adults, as an earlier diagnosis of mild CKD does not equate to clinical benefits, but could lead to harms of unnecessary interventions and patient anxiety.

The following highlights are a brief overview of guideline updates, drug approvals, and diagnostics relevant to geriatric medicine from June 2021 to April 2022, some of which were discussed at the American Geriatrics Society conference in May. I selected these topics as they were among the most discussed by my colleagues in geriatric medicine and inquired about by my primary care patients in geriatric medicine clinic. I hope that these updates provide primary care clinicians who care for older adults with more context and background information regarding new Alzheimer’s disease therapy to better answer patient inquiries, and to feel empowered to deprescribe aspirin and reframe the diagnostic criteria of chronic kidney disease (CKD).

Aspirin for primary prevention

It was welcome news in the geriatrics community when the United States Preventive Services Task Force updated their guidelines in April 2022 to recommend against the initiation of aspirin for primary prevention in adults aged 60 or older. This recommendation was based on studies that found that net benefits of CVD prevention in older adults are outweighed by risk of bleeding.¹

The risk of bleeding increases with age and can occur in individuals without common risk factors for bleeding, such as prior gastrointestinal bleeding, peptic ulcer disease, concurrent NSAID use, or corticosteroid use.

While it may be easier to not initiate aspirin for primary prevention, deprescribing aspirin for patients who have been on aspirin long term for primary prevention presents more of a challenge. Modeling data from the USPTSF suggest stopping aspirin at age 75 for those taking aspirin for primary prevention.²

Behavioral change, particularly for patients who have been on aspirin for decades, can be difficult. A 2021 study by Green et al. found that language that resonates the most with older adults when deprescribing emphasized the side effects rather than statements such as “this will not help you” or “do not need anymore.”3
