Factors Associated with Readmission of Patients at a University Hospital Psychiatric Ward in Iran

Objectives. Readmission has a major role in the reduction of the quality of life and the increase in the years of lost life. The main objectives of this study were to answer to the following research questions. (a) What was the readmission rate? (b) What were the social, demographic, and clinical characteristics of patients admitted to the Psychiatric Emergency Service at Nour University Hospital, affiliated to Isfahan University of Medical Sciences, Isfahan, Iran? (c) What were the effective factors on readmission? Method. This cross-sectional study was conducted on a total number of 3935 patients who were admitted to Isfahan University Hospital Psychiatric Ward in Isfahan, Iran, from 2004 to 2010. Gender, age, marital status, education, self-report history of previous admission, type of psychiatric disorder, substance misuse, suicide, and the length of the current psychiatric disorder were collected from the registered medical files of patients. The data were analysed using the negative binomial regression model. Results. We found that factors such as psychiatric anxiety disorder, bipolar I, bipolar II, psychotic disorder, depression, and self report history of previous admission were statistically significant in the number of readmissions using the negative binomial model. Conclusion. Readmission to the psychiatric ward is mainly predictable by the type of diagnosis and psychosocial supports.
