Medical outreach to homeless substance users in New York City: preliminary results.

An innovative, experimental, medical out-reach initiative, using a fully-equipped mobile medical van with a staff of 2 part-time physicians, a physician assistant, a social worker, and a driver/medical aid serving the needs of 1048, mostly male, minority group, high-level, homeless New York City substance users with infectious diseases is described. The study sample (N = 250) was divided into experimental S's who received Intensive case management and a control group who could choose to refer themselves to the SW. Biological tests revealed high rates of cocaine use and infectious diseases. Preliminary 4-month outcomes (N = 128) showed reductions in drug use, homelessness and health complaints in both groups; experimental subjects compared with controls received more Public Assistance and had fewer emergency room visits.
