Predictors of civil and forensic inpatient psychiatric readmissions at a Public Mental Health Hospital

Abstract

Inpatient psychiatric readmissions are increasingly prevalent and associated with worse prognostic outcomes and high economic costs, regardless of the medicolegal ramifications that necessitate them. Unlike most general medical readmissions, psychiatric readmissions are commonly warranted for both medical and legal purposes. However, studies focusing on analyzing the predictors of inpatient psychiatric readmission and their relationship to civil versus forensic readmission are limited. The purpose of this study was to examine the predictors of psychiatric readmission among civil and forensic patients admitted to a psychiatric hospital. In this retrospective chart review, we extrapolated data from medical records of 741 patients admitted from 2012 to 2017 with follow up until 2019. Analyses involved chi-square tests for comparing the distribution of demographic and clinical variables between forensic and civil readmission, and Cox regression to determine predictors of time to first readmission. Our results show that race, diagnosis, restraint/seclusion, type of admission, and disposition are significantly associated with an increased risk of psychiatric readmission. This study has important implications for healthcare providers and policy makers in revising mental health policies and improving systems-based practices for the mental health system. Future efforts in improving community psychiatric services and enhancing inpatient therapeutic environment may reduce psychiatric readmissions.
