Risk Factors for Psychiatric Hospital Admission for Participants in California's Full-Service Partnership Program.

This study investigated the demographic and clinical predictors of psychiatric hospitalization during the first 2 years of treatment for adults participating in the full-service partnership (FSP) program, based on Assertive Community Treatment, in a large county in northern California. Clinical and demographic characteristics, data on prior hospitalizations, length of enrollment, and living situation for 328 FSP participants were collected from the county's internal billing system and the California Department of Health Care Services. In univariate models, the probability of hospitalization varied by diagnosis, age, and hospitalization history. In the multivariate model, younger age and frequent hospitalization prior to enrollment predicted hospitalization during enrollment. Findings support prior research on hospital recidivism and may be beneficial in refining future strategies for meeting the needs of adults with serious mental illness.
