Engaging Homeless Veterans in Primary Care

One out of three homeless men and nearly one quarter of all homeless adults are Veterans. This translates to almost 200,000 Veterans being homeless on any given night. The Department of Veteran Affairs (VA) is a major service provider to homeless persons and has developed several very successful and innovative programs that have been effective in securing housing, economic stability and needed services for these men and women. However, despite these efforts in many communities, Veterans are not accessing these services despite aggressive outreach and state-of-the art programming. The investigators are conducting a prospective randomized controlled trial to test the hypothesis that a personalized health assessment linked to community outreach is more likely to both engage the homeless Veteran in a primary care based chronic disease management model and to sustain that care and associated behavior changes necessary to exit homelessness. The key questions to be addressed in this study are: (1) Will a community-based health-oriented outreach increase health seeking behavior in the intervention group?; (2) can initial engagement be sustained in a continuity care model in this population?; (3) will this intervention facilitate changes/improvements in health seeking behavior that include participation in substance abuse treatment care, compliance with mental health care, and enrollment in VA-based employment/financial support programs?; and (4) can this intervention impact chronic disease management of key cardiovascular risk indicators that disproportionately affect homeless persons?; and (5) do any observed changes correlate with serial behavioral measures and qualitative assessments?

The investigators' working hypothesis is that a targeted outreach to homeless persons that capitalizes on either established or newly realized physical health concerns to affect both health seeking behavior and sustained behavior change. It is grounded in two complementary behavioral models: the Behavioral Model for Vulnerable Populations and the body of research describing intrinsic versus extrinsic motivators for sustained behavior change.

Two hundred and eighty homeless Veterans will be randomized to receive either a personalized health assessment based outreach or usual care (social work/housing focused) outreach. Baseline assessments will include demographics, medical, mental health and substance use co-morbidities, pre-intervention health seeking behavior, readiness for behavior change (URICA), motivation for health care. Serial assessments at months 1, and 6 will assess evolving readiness and motivation as well as changes in their homeless status (sheltering, employment/income, etc.) Actual utilization of services will be assessed using the CPRS electronic medical records.
