Housing instability significantly impedes HIV-related outcomes, such as engagement in
care, ART adherence, and viral suppression. Structural racism and poverty exacerbate
these disparities, particularly for racial and sexual minorities. To address this, the
PDPH developed the AAY program, which combines rent support (up to 48 months), housing
medical case management (MCM), and intensive housing counseling, following
client-centered, harm-reduction principles.
This hybrid type 1 effectiveness-implementation study will evaluate the effects of the
AAY intervention on health, economic, and psychological outcomes. PWH experiencing
homelessness or severe housing instability will be prioritized for the program. The
lottery-based design will allow researchers to observe differences between those granted
immediate program access and those on the waitlist (who will receive standard of care
treatment and serve as the control group). The primary outcomes of interest are HIV viral
suppression (defined as <200 copies/mL) and ART adherence, measured via pharmacy refill
data. Secondary outcomes include housing security, food security, financial stress,
psychological distress, and health-related quality of life.
Researchers will use mixed methods to collect data over 36 months. Quantitative data will
include pre- and post-program surveys, pharmacy refill records, and PDPH surveillance
data. Qualitative data will be gathered through semi-structured interviews with key
stakeholders, including program participants, waitlisted individuals, housing MCMs, and
city leaders. These interviews will explore the program's acceptability, implementation
challenges, and pathways through which housing support influences HIV outcomes.
Approximately 200 participants will be enrolled in the survey study, with data collected
at baseline and at 6, 12, 24, and 36 months. Key implementation outcomes, such as the
program's reach, sustainment, and costs, will also be analyzed to inform scalability.
This study will provide critical evidence on how housing interventions can reduce health
inequities and improve HIV-related outcomes, offering actionable insights for
policymakers and public health leaders in Philadelphia and beyond.
