Interventions providing coordinated treatment and support for homeless adults usually results in greater health improvements than does the prevailing sporadic and substandard care, according to a new review of studies. "We found evidence that a substantial number of different types of programs and interventions are effective in improving the health of homeless adults, especially those with mental illness and homelessness," says lead investigator Stephen Hwang, M.D., of the Centre for Research on Inner City Health at St. Michael's Hospital in Toronto.
