Chicago Housing for Health Partnership: HIV Outcomes David Buchanan MD MS, Romina Kee MD MPH, Laura Sadowski MD MPH, Diana Garcia MPH North American Housing & HIV/AIDS Research Summit June 4, 2009
What is the root cause of poor health among homeless patients? • Does homelessness lead to poor health? • Providing housing would improve health • Do other social factors lead to both poor health and homelessness? • Providing housing would not help much
Health Outcomes: Why HIV? • Top qualifying medical illness • Effective treatments for HIV exist • Housing stability may impact the effectiveness of HIV treatment • Markers for HIV Disease progression
HIV Outcomes: Hypothesis Providing permanent housing and intensive case management to hospitalized HIV+ homeless patients will improve their survival with an intact immune system one year later
HIV Outcomes: Methods • Inclusion: Enrolled at Stroger Hospital, HIV+ • 1 year later - CD4 count & Viral load • 1º Endpoint – Survival with intact immunity • Alive with CD4 > 200 and Viral Load < 100K • 2º Endpoints • CD4 Counts • HIV viral loads • Undetectable viral loads
HIV Outcomes – Data Sources • 105 Eligible (HIV+ Stroger Hosp enrollees) • 66 Visited Reference Lab or Died - 63% • 28 Labs - Outpatient usual care - 27% • 11 No labs & not deceased - 10%
Survival with intact immunity P = 0.04
CD4 (T Cell) Counts P = 0.23 Patients CD4 Counts - higher is better
HIV Viral Loads P = 0.03 for trend Patients Viral Loads - lower number is better
Viral Load (Mean) P = 0.03 MeanViral Load
