Inpatient suicide in a Chinese psychiatric hospital.
Little is known about the risk factors for suicide among psychiatric inpatients in China. In this study we identified the risk factors of suicide among psychiatric inpatients at Guangzhou Psychiatric Hospital. All psychiatric inpatients who died by suicide during the 1956-2005 period were included in this study. Using a case-control design, 64 inpatients with schizophrenia who died by suicide were compared with a matched 64 controls. The results indicate that the rate of suicide was 133.1/100,000 admissions (95%CI 103.4-162.9). There were no significant differences in the method, location, or time of suicide between male and female inpatients. The number of hospitalizations was significantly larger in the suicide group than that in the control group. In logistic regression analyses, guilty thought, depressive mood, and suicidal ideation and suicide attempt 1 month before hospital admission were identified as independent predictors of suicide among inpatients with schizophrenia. The findings of risk factors for schizophrenic inpatient suicide should be taken into account when developing interventions to prevent suicide among these patients.
