Longitudinal Determinants of Housing Stability Among People Living With HIV/AIDS Experiencing Homelessness

Mobile Health Tool to Capture Social Determinants of Health and Their Impact on HIV Treatment Outcomes Among People Who Use Drugs: Pilot Feasibility Study

Background

Active substance use, food or housing insecurity, and criminal legal system involvement can disrupt HIV care for people living with HIV and opioid use disorder (OUD). These social determinants of health are not routinely captured in clinical settings.

Objective

We evaluated whether real-time reports of social and behavioral factors using a smartphone app could predict viral nonsuppression and missed care visits to inform future mobile health interventions.

Methods

We enrolled 59 participants from the AIDS Linked to the Intravenous Experience (ALIVE) Study in Baltimore, Maryland, into a 12-month substudy between February 2017 and October 2018. Participants were eligible if they had OUD and had either a measured HIV RNA ≥1000 copies/mL or a ≥1-month lapse in antiretroviral therapy in the preceding 2 years. Participants received a smartphone and reported HIV medication adherence, drug use or injection, and several disruptive life events, including not having a place to sleep at night, skipping a meal due to lack of income, being stopped by police, being arrested, or experiencing violence on a weekly basis, through a survey on a mobile health app. We described weekly survey completion and investigated which factors were associated with viral nonsuppression (HIV RNA ≥200 copies/mL) or a missed care visit using logistic regression with generalized estimating equations adjusted for age, gender, smartphone comfort, and drug use.

Results

Participants were predominantly male (36/59, 61%), Black (53/59, 90%), and had a median of 53 years old. At baseline, 16% (6/38) were virally unsuppressed. Participants completed an average of 23.3 (SD 16.3) total surveys and reported missing a dose of antiretroviral therapy, using or injecting drugs, or experiencing any disruptive life events on an average of 13.1 (SD 9.8) weekly surveys over 1 year. Reporting use of any drugs (adjusted odds ratio [aOR] 2.3, 95% CI 1.4-3.7), injecting drugs (aOR 2.3, 95% CI 1.3-3.9), and noncompletion of all surveys (aOR 1.6, 95% CI 1.1-2.2) were associated with missing a scheduled care visit over the subsequent 30 days. Missing ≥2 antiretroviral medication doses within 1 week was associated with HIV viral nonsuppression (aOR 3.7, 95% CI: 1.2-11.1) in the subsequent 30 days.

Conclusions

Mobile health apps can capture risk factors that predict viral nonsuppression and missed care visits among people living with HIV who have OUD. Using mobile health tools to detect sociobehavioral factors that occur prior to treatment disengagement may facilitate early intervention by health care teams.

Management of HIV in the older adults: Clinical and public health challenge

As a result of significant advances in antiretroviral therapy (ART), the number of people living with human immunodeficiency virus (PLWH) who are alive well into their senior years has increased significantly in recent years. While increased life expectancy is a highly desired outcome for PLWH, it brings with it a number of challenges that are only now starting to be understood and fully appreciated. These challenges include higher rates of co-morbidities, polypharmacy, drug side effects, and cognitive deficits, as well as numerous psychosocial issues such as stigma, loneliness, and depression. Older PLWH also face challenges related to housing, health insurance, and long-term care. This review will discuss many of the challenges faced by older PLWH and present clinical and public health responses with suggested interventions that may improve outcomes for this population.

Addressing HIV and Homelessness During COVID-19: A Community-Based Demonstration Project

People experiencing homelessness are at increased risk for HIV, and people with HIV (PWH) experiencing homelessness are more likely to experience suboptimal HIV health outcomes than PWH with stable housing. Within Alabama, a state prioritized in the Ending the HIV Epidemic initiative, Jefferson County consistently has the highest number of new HIV diagnoses as well as a high percentage of the state's homeless population. To address the twin epidemics of both HIV and homelessness within the high-priority setting of Jefferson County, Alabama, this 1-year community-based project, Ending the HIV Epidemic: Addressing HIV Health and Homelessness (AH3), sought to increase HIV testing and linkage to care among this population by placing a full-time case manager trained in HIV testing and case management at a homeless shelter. Results demonstrated that HIV testing was highly acceptable: 733 individuals were offered a test, and only 2.7% (n = 20) declined. Nine previously diagnosed, out of care PWH and one newly diagnosed PWH were identified through AH3 testing efforts. Of these, five (50%) were linked to care at a local HIV clinic. The remaining five PWH left the shelter before they could be linked to care. Just 10 shelter guests expressed interest in taking PrEP (just 1.4% of guests who tested negative for HIV), and only one of these linked to PrEP care. Future health promotion programs are needed to address mental health and other ancillary needs among this population, as well as programs that provide access to PrEP and other HIV prevention services.

"It Comes in Steps and Stages": Experiences of People Living with HIV in Achieving Employment

People living with HIV who are seeking jobs experience unique barriers to obtaining employment at the individual, group, and community levels. Traditional employment assistance programs can provide support but may not be tailored to some people living with HIV who often experience barriers to work related to their social needs (such as housing instability) or their lack of consistent engagement in the workforce. To understand how people living with HIV return to work, in-depth interviews were conducted with 43 participants enrolled in interventions coordinating HIV care with housing and employment services at eight sites across the US. Four themes emerged on strategies to increase employment: (1) assessing and responding to employment needs that align with their socio-economic environment; (2) using social networks among family and friends for referrals and support; (3) engaging with navigators who are able to connect clients to skills building opportunities and job resources; and (4) addressing the system barriers such as helping with unmet basic needs (e.g. transportation), finding employers who can accommodate workers with income limits associated with public benefits, and helping immigrants, transgender individuals, and people experiencing homelessness secure legal documentsthat facilitate entry into employment by reducing stigmatized identities.

Housing Subsidies and Housing Stability are Associated with Better HIV Medical Outcomes Among Persons Who Experienced Homelessness and Live with HIV and Mental Illness or Substance Use Disorder

Among 958 applicants to a supportive housing program for low-income persons living with HIV (PLWH) and mental illness or a substance use disorder, we assessed impacts of housing placement on housing stability, HIV care engagement, and viral suppression. Surveillance and administrative datasets provided medical and residence information, including stable (e.g., rental assistance, supportive housing) and unstable (e.g., emergency shelter) government-subsidized housing. Sequence analysis identified a "quick stable housing" pattern for 67% of persons placed by this program within 2 years, vs. 28% of unplaced. Compared with unplaced persons not achieving stable housing quickly, persons quickly achieving stable housing were more likely to engage in care, whether placed (per Poisson regression, ARR: 1.14;95% CI 1.09-1.20) or unplaced (1.19;1.13-1.25) by this program, and to be virally suppressed, whether placed (1.22;1.03-1.44) or unplaced (1.26, 1.03-1.56) by this program. Housing programs can help homeless PLWH secure stable housing quickly, manage their infection, and prevent transmission.

Pathways to housing stability and viral suppression for people living with HIV/AIDS: Findings from the Building a Medical Home for Multiply Diagnosed HIV-positive Homeless Populations initiative

Background

People with HIV with co-occurring substance use and mental health diagnoses who are unstably housed have poorer outcomes for retention in care and viral suppression. Navigation models are a potential strategy to help this vulnerable population obtain the necessary medical and non-medical services across multiple service systems. The Health Resources and Services Administration’s Special Projects of National Significance: “Building a Medical Home for Multiply-Diagnosed HIV-positive Homeless Populations initiative 2012–2017 found that navigation models may be an effective intervention to support people with HIV with unstable housing improve HIV health outcomes. However, there is limited information about the mechanisms by which this intervention works. In this article, we explore the participant and program factors for achieving stable housing at 6 months and how these factors influence HIV health outcomes.

Methods and findings

This was a prospective study of 471 unstably housed people with HIV enrolled in a navigation intervention across nine sites in the United Stated from 2013–2017. All sites provided HIV primary medical care. Eight sites were located in urban areas and one site served a predominantly rural population. Two sites were federally qualified health centers, three were city or county health departments, one site was a comprehensive HIV/AIDS service organization, and three sites were outpatient or mobile clinics affiliated with a university -based or hospital system. Data were collected via interview and medical chart review at baseline, post 6 and 12 months. Type and dose of navigation activities were collected via a standardized encounter form. We used a path analysis model with housing stability at 6 months as the mediator to examine the direct and indirect effects of participant’s socio-demographics and risk factors and navigation on viral suppression and retention in care at 12 months. Housing stability at 6 months was associated with male gender, younger age, viral suppression at baseline, having a lower risk for opiate use, recent homelessness, lower risk of food insecurity, and a longer length of time living with HIV. Participants who increased self-efficacy with obtaining help by 6 months had significantly higher odds of achieving housing stability. Stable housing, fewer unmet needs, moderate to high risk for opiate use, and viral suppression at baseline had a direct effect on viral suppression at 12 months. The intensity of navigation contact had no direct effect on housing stability and a mixed direct effect on viral suppression. Recent diagnosis with HIV, women, greater social support, increased self-efficacy and higher intensity of navigation contact had a direct effect on improved retention in HIV primary care at 12 months.

Conclusions

In this sample of people with HIV who are experiencing homelessness, housing stability had a significant direct path to viral suppression. Navigation activities did not have a direct effect on the path to housing stability but were directly related to retention in care. These results identify key populations and factors to target resources and policies for addressing the health and social unmet needs of people with HIV to achieve housing stability and HIV health outcomes.
