OBJECTIVES: This study examined a strategy to prevent homelessness among individuals with severe mental illness by providing a bridge between institutional and community care. METHODS: Ninety-six men with severe mental illness who were entering community housing from a shelter institution were randomized to receive 9 months of a "critical time" intervention plus usual services or usual services only. The primary analysis compared the mean number of homeless nights for the two groups during the 18-month follow-up period. To elucidate time trends, survival curves were used. RESULTS: Over the 18-month follow-up period, the average number of homeless nights was 30 for the critical time intervention group and 91 for the usual services group. Survival curves showed that after the 9-month period of active intervention, the difference between the two groups did not diminish. CONCLUSIONS: Strategies that focus on a critical time of transition may contribute to the prevention of recurrent homelessness among individuals with mental illness, even after the period of active intervention.

Although in Brazil the rate increased 29.5% in 26 years, the national rate is still considered to be low when compared to worldwide suicide rates (average of 4.9 per 100,000 inhabitants). Suicide rates in Brazilian regions vary broadly, ranging from 2.7 to 9.3.

This intervention successfully reduced sexual risk behaviors of homeless men with mental illness. The effect diminished over 18 months but did not disappear. Similar approaches may be effective in other impaired high-risk groups.

We report on the prevalence of human immunodeficiency virus (HIV) infection among psychiatric patients in a New York City shelter for homeless men. We reviewed the records of all 90 men discharged from the shelter psychiatry program to community housing over a 2-year period. HIV serostatus was recorded for 62 of the 90 men. Of these 62, 12 (19.4%) were positive. There were 28 men whose serostatus was not recorded. Data on the HIV risk behaviors of these 28 men suggested that seroprevalence could have been similarly high among them. The results indicate an urgent need to develop and apply preventive interventions for HIV in this population.

S: Although difficult to conduct, studies of the cost-effectiveness of community mental health programs can yield rich information for policy makers and program planners. The critical time intervention program is not only an effective method to reduce recurrent homelessness among persons with severe mental illness but also represents a cost-effective alternative to the status quo.
