Evaluation of Risk Factors for Antipsychotic Polypharmacy in Inpatient Psychiatry Units of a Community Hospital: A Retrospective Analysis.

Antipsychotic polypharmacy (APP) is a common practice while treating severe mental illness but the benefits of APP over antipsychotic monotherapy is controversial. This is a retrospective analysis comparing risk factors for people on APP and those on non-APP in inpatient psychiatry units. Two years data with 72 people in non-APP group and 82 people in APP group were analyzed quantitatively. The diagnoses of schizoaffective disorder (OR 11.5), schizophrenia (OR 4.65) and depression (OR 0.31), and history of > 2 psychiatric admissions (OR 3.2) and > 2 psychiatric emergency visits (OR 2.87) in 2 years were studied as potential risk factors for APP. Similarly, history of violence (OR 1.7) and history of substance abuse (OR 0.51) were also studied. Schizophrenia spectrum disorder, higher number of psychiatric hospitalizations, and psychiatric emergency visits were positively associated while depression and substance abuse were negatively associated with APP in our study.
