The impact of critical time intervention in reducing psychiatric rehospitalization after hospital discharge

Psychiatr Serv. 2012 Sep 1;63(9):935-7. doi: 10.1176/


Objectives: This study examined the impact of critical time intervention (CTI) in reducing rehospitalization among formerly homeless individuals with severe and persistent mental illness after discharge from inpatient psychiatric treatment.

Methods: CTI is a nine-month care coordination intervention designed to support persons with severe mental illness in the transition from institutions to community living. After discharge from inpatient psychiatric treatment, 150 previously homeless men and women were randomly assigned to receive either usual services only or CTI in addition to usual services. Study participants were assessed every six weeks for 18 months after entering the community.

Results: At the end of the follow-up period, psychiatric rehospitalization was significantly lower for the group assigned to CTI compared with the usual services group (odds ratio=.11, 95% confidence interval=.01-.96).

Conclusions: This study demonstrated that CTI, primarily designed to prevent recurrent homelessness, also reduced the occurrence of rehospitalization after discharge.
