Increasing access to mental health and substance use services, particularly through integrated care models, as well as addressing issues of HIV-related stigma, may positively impact engagement in HIV clinical care.

The VHA is the largest single provider of human immunodeficiency virus (HIV) care in the U.S., with over 26,000 HIV-positive veterans in care in 2013.1 HIV care in the VHA is delivered across 152 hospitals and nearly 1,400 health care facilities, including
community-based outpatient clinics, skilled nursing facilities, veteran centers, rehabilitation centers, hospices, and domiciliaries in the U.S. and its territories.2

The structure of HIV care in the VHA has been described in more detail elsewhere and, for context, is briefly highlighted here.3 Many veterans with HIV infection receive both HIV care and primary care through an infectious disease or HIV specialist, whereas others receive HIV care and primary care in separate clinics. Every medical center has a designated HIV lead clinician who serves as the point of contact for the VHA National HIV Program. This network facilitates rapid dissemination of policy changes and clinical updates to HIV providers nationally, as well communication to the National HIV Program about barriers and challenges to providing high-quality care at the local level. The National HIV Program monitors and evaluates comprehensive HIV care programming, which includes increasing HIV testing, availability of pre-exposure prophylaxis, and access to and quality of comorbidity care (for more information on VHA HIV care, please visit: http://www.hiv.va.gov).

Comorbidity care is a particular focus of the National HIV Program. The majority of veterans with HIV in VHA care are now in late middle-age; in 2011, 66% were aged between 50 and 69 years.4 As the population of veterans with HIV grows older, age-related chronic medical comorbidities (eg, diabetes mellitus, cardiovascular disease) and mental health considerations (eg, cognitive impairment, depression, substance use) become increasingly critical areas of clinical focus at the individual and the population level.

The HIV care continuum provides a useful model to conceptualize critical components of providing high-quality comprehensive HIV clinical care, including diagnosis, linkage to care, retention in care, prescription of antiretroviral therapy (ART), and viral suppression. Achieving virologic suppression is the primary goal of HIV care. It decreases morbidity and mortality for the HIV-infected individual and decreases the risk of transmission to others.5

This continuum of care is used increasingly by federal agencies and other health care systems to assess engagement at each critical juncture. The Centers for Disease Control and Prevention has estimated that, due to significant drop-offs between each step of the continuum, only 25% of the 1.1 million people living with HIV in the U. S. are virally suppressed (Figure 1).6,7

Recently, the HIV care continuum cascade was used to assess HIV care within a VA medical facility.8 The authors assessed performance along the HIV care continuum at the Atlanta VAMC (AVAMC) Infectious Disease Clinic, an urban clinic providing care to over 1,400 veterans with HIV. Using an independent stage categorization analysis, they found that the AVAMC outperformed national estimates at every stage of the HIV care continuum. Notably, 62.8% of the clinical population diagnosed with HIV was prescribed ART and 52.3% had achieved viral suppression, more than double the national rate (Figure 2).8-10 Although national VHA data on the HIV Care Continuum Initiative are not currently available, this study helps to illustrate the high quality of HIV care in the VHA relative to other national samples.

Mental Health and Substance Use

Although individual facilities within VHA may perform better across the care continuum compared with national samples, as a health care system, significant dropoffs remain at each stage, particularly in the transition from linkage to care to retention in care. The barriers to engagement in care at various steps along this continuum are not well understood, although mental health and substance use disorder (MH/SUD) comorbidities likely play an important role.

Mental health and substance use disorder comorbidities impact over half of veterans with HIV infection in VHA care. In 2012, 55% of veterans with HIV infection in care had ever been diagnosed with depression, 31% with anxiety, 16% with posttraumatic stress disorder (PTSD), and 62% with any mental illness (Table).11 Substance use is also quite prevalent in veterans with HIV infection, with 34% reporting a history of alcohol abuse, 28% a history of stimulant use, and 16% a history of cannabis use in 2012; nearly 50% reported tobacco use.

Compared with that of the general population, MH/SUDs are much higher among people living with HIV/acquired immune deficiency syndrome (AIDS) and higher still among veterans living with HIV/AIDS.11-13 Mental health conditions such as depression, anxiety and PTSD as well as substance use have been linked not only to increases in HIV risk behavior, but also to more rapid progression of HIV and increases in AIDSdefining illnesses and death.14-16 The high burden of MH/SUD among veterans with HIV is further complicated by the fact that this is an aging population. The risk of HIV-associated neurocognitive disorders (HAND) as well as non–HIV-related neurocognitive disorders increases with age.17,18 These risks may be higher for those with comorbid MH/SUD, and this interaction may increase patients’ vulnerability to HAND.12,19,20

The HIV care continuum is characterized by engagement at each step. Psychiatric and substance use problems represent potential engagementlimiting comorbidities. Several studies highlight the importance of addressing MH/SUDs that have adverse effects on adherence, linkage to and retention in care, and care utilization patterns.13,18,21-24 HIV-related stigma may also play a significant role in disengagement in care, adherence, patient satisfaction with care, and follow-up.25-28

Overall, integrated HIV care has been found to positively impact hospital utilization, quality of life and functioning, adherence, patient satisfaction, and process outcomes.29 Integrated HIV care is a specific intervention that could positively impact the HIV care continuum, particularly in managing depression and substance use.28,30,31 In the VHA, integrated HIV care is associated with increased access to mental health services and increased viral suppression compared with nonintegrated HIV clinics in VHA.32,33

A qualitative study of care integration found that in VHA HIV clinics that were integrated, patients reported less stigma and more positive relationships with their providers.34 The VHA Office of Public Health, in collaboration with the Office of Academic Affiliations, has supported the expansion of a postdoctoral fellowship in clinical psychology with a specific focus on integrated HIV and hepatitis C clinical care in an effort to increase the availability of mental health providers specifically trained to address MH/SUDs in the HIV-infected population. This national fellowship program has been described in detail elsewhere.11

Conclusion

The HIV care continuum is a useful model to describe the cascade of HIV care and opportunities for points of engagement. Although VHA may be performing higher along the care continuum than national samples, there is still much work to be done to better understand the barriers to engagement and interventions that will boost each step so that more veterans with HIV infection achieve viral suppression.

Increasing access to mental health and substance use services, particularly through integrated care models, as well as addressing issues of HIV-related stigma, may positively impact engagement in HIV clinical care. Given the use of electronic medical records, the availability of MH/SUD treatment, and the increasing emphasis on integrated HIV care at multiple facilities across the system, the VHA is well positioned to address gaps in care, with a particular focus on the role that MH/SUDs have in HIV care continuum drop-offs.
