The purpose of this study was to identify the psychosocial factors which influence transitioning HIV positive clients without primary medical care to a case management agency within 6 weeks by a city brokerage agency. People living with HIV who reported being in a social support group and those who requested assistance with meeting their basic needs were significantly more likely to attend their first case management appointment within 6 weeks (adjusted OR 1.91 95% CI 1.22-2.97 and OR 1.24 95% CI 1.01-1.54, respectively). Individuals requesting medical care or substance abuse treatment were less likely to accomplish transitioning (adjusted OR 0.75 95% CI 0.59-0.95 and adjusted OR 0.70 95% CI 0.53-0.91, respectively). The implications of this study for improving the effectiveness of brokering case management for those with HIV are discussed.
