Purpose of the Study: Intensive case management (ICM) holds promise in reducing 30-day inpatient psychiatric recidivism and associated costs. The purpose of this study is to determine the impact of ICM on 30-day inpatient psychiatric recidivism and associated costs among adult health plan members at elevated risk of psychiatric hospitalization.


Primary Practice Setting: Psychiatric settings.


Methodology and Sample: An intent-to-treat, historical control design was used to examine utilization differences between 305 intervention group members eligible to receive ICM services and a cohort of 347 baseline group members identified retrospectively using identical criteria during a similar 1-year time period before implementation of the ICM program.


Results: The 30-day recidivism rate for baseline group members was 29.11% as compared with 8.52% among intervention group members. Logistic regression results indicated a significant main effect for the ICM intervention. Inpatient psychiatric costs for the 30-day outcome period were on $1,528.91 lower per member in the intervention group. Regression results indicated a main effect for the ICM intervention. Program costs were estimated at $41.39 per member.


Implications for Case Management Practice: The ICM intervention was associated with significant reductions in inpatient, psychiatric 30-day readmission rates, and associated costs among adult members who are at elevated risk of inpatient, psychiatric recidivism. The intervention, enrollment process, and measurement strategies can be adapted for use by case managers in a variety of different settings.
