In the present study, a cohort of patients who came to a psychiatric emergency room in a general hospital, and were not referred for hospitalization, were analyzed in regard to the amount and rate of subsequent contact with community mental health and substance abuse agencies. Patterns of service receipt and the differential impact of service use on hospitalization and/or return visits were analyzed by three major problem types: (1) psychiatric; (2) psychiatric/substance abuse; and (3) substance abuse. The analysis of these subgroups yielded valuable information about how the service system and/or different groups of patients in crisis respond to the system.
