Brief critical time intervention to reduce psychiatric rehospitalization

Abstract

Objective: The study investigated the association between implementation of a brief critical time intervention (BCTI) model and occurrence of early and long-term psychiatric readmission of adults with serious mental illness. Methods: A sample of 149 adults with a psychiatric inpatient readmission within 30 days of a prior psychiatric hospitalization was referred to an acute level of service coordination (ASC) available at six provider organizations implementing BCTI. Activities important to the delivery of BCTI were monitored and supported. A comparison cohort of 224 adults served by ASC at the same organizations before implementation of BCTI was derived from administrative data. Frequencies of behavioral health service utilization and readmission rates for the intervention and comparison cohorts within 30 and up to 180 days of the prior readmission were compared. Results: Utilization rates of mental health and substance use disorder services were similar for both cohorts postdischarge. The proportion of individuals readmitted within 30 days of a discharge was lower for the BCTI cohort (28%) than the comparison cohort (47%) (p
