Abstract

Objective: This study examined the use, demographic and clinical correlates of antipsychoticpolypharmacy (APP) and its associations with treatment satisfaction and quality of life (QOL) inschizophrenia patients in China. 

Method: A total of 4239 patients in 45 nationwide Chinese psychiatric hospitals/centers were interviewed in 2012 in the third cross-sectional study, with the first two having been conducted in2002 and 2006. Patients' socio-demographic and clinical characteristics, including psychopathology, side effects, satisfaction with treatment and QOL, were recorded using a standardized protocol and data collection procedure. 

Results: The proportion of APP prescriptions in 2012 was 34.2%, which was significantly higher than the frequency of APP in 2002 (26.1%) and 2006 (26.4%) (p<0.001). Of patients on APP, 91.1% received two antipsychotics, 8.6% received three and 0.3% received four or more antipsychotics. Multiple logistic regression analyses revealed that compared to those on antipsychotic monotherapy, patientson APP and their families had lower satisfaction with treatment, had higher QOL in the mental domain, younger age of onset, more side effects, higher doses of antipsychotics and were more likely to receive first-generation antipsychotics and less likely to receive benzodiazepines (total R-2=0.31, p<0.001). 

Conclusions: APP was found in about one in three schizophrenia patients. The prevalence of APP seems to have been increasing since 2002. Considering the increased frequency of drug-induced side effects and the patients' and their relatives' dissatisfaction with antipsychotic treatment, further examination of the rationale and appropriateness of APP and its alternatives is warranted.
