Objective Little is known about the use of electroconvulsive therapy (ECT) in older Chinese psychiatric patients. This study examined the frequency of ECT and the demographic and clinical correlates in older psychiatric patients hospitalized in a large psychiatric institution in Beijing, China. Methods This was a retrospective chart review of 2339 inpatients aged 60 years and older treated over a period of 8 years (2007-2013) in a university-affiliated psychiatric institution in Beijing. Sociodemographic and clinical data were collected from the electronic chart management system for discharged patients. Results The rate of ECT use was 28.1% in the whole sample; 37.9% in those with bipolar disorders, 43.6% in major depression, 21.2% in schizophrenia, and 10.7% in other diagnoses. ECT ("ECT group") was associated with 60-65-year age group, high risk for suicide and low risk for falls at the time of admission, use of mood stabilizers and antidepressants, lack of health insurance, and having major medical conditions and diagnosis of major depression. The above significant correlates explained 24.9% of the variance of ECT use (p < 0.001). Conclusions In a major psychiatric hospital in China, the use of ECT was common among older patients. ECT use in older patients treated in other clinical settings warrants further investigations.
