Time to readmission in psychiatric inpatients with a therapeutic leave

AIMS Interventions to decrease readmissions in psychiatric patients are urgently needed. In Switzerland therapeutic leave (TL) composes a cornerstone of inpatient treatment. TL is a planned time-limited absence from the inpatient ward giving patients the opportunity to test their resilience in their usual environment. Evidence of its applicability as an intervention reducing readmissions is lacking. Therefore, our objective was to examine the association between TL and readmission risk. METHODS Using the Kaplan-Meier curve we compared the time to readmission of 3'302 inpatients at the UPK Basel with and without TL. Cox regression was applied, integrating other covariates associated with readmission. RESULTS The Kaplan-Meier curve indicated longer cumulative survival in patients with TL. The log-rank test implied statistical significance (χ2(1) = 18.8, p
