Sumario:PURPOSE: To describe the mortality rate and cause of death among Han Chinese schizophrenia patients and to explore the risk factors affecting survival. METHODS: We performed a retrospective analysis of death among patients with schizophrenia from Jan 1, 2012, to Dec 31, 2019, using the Severe Mental Disorders Information System of Shandong Province (henceforth referred to as the SMDI system) in Shandong, China. The cohort included 72,102 patients, and 11,766 patients died during follow-up. The data in this cohort study were derived from the SMDI system. We calculated the crude mortality rate and standardized mortality rate (SMR, standardized according to the sex and age composition of the population in Shandong Province) for patients with schizophrenia. Cox regression analysis was used to analyze the risk factors affecting patient survival, and the statistical index was the hazard ratio (HR). RESULTS: The mean age of the cohort patients was 47.21±14.05 years; 51.79% were males, and 48.21% were females. Among them, 68.98% (49,735) had only a primary education level, 85.36% (61,549) were farmers, 64.37% (46,413) were married, and 94.01% (67,775) received community management. A total of 16.32% of the cohort died. The SMR in patients with schizophrenia was 4.9, and it was higher for males than females (4.99 versus 4.82). Among the 6 registered causes of death, physical illness had the highest SMR (5.15), followed by other causes of death (4.86), mental illness-related complications (4.57), homicide (4.31), accidents (4.13), and suicide (3.87). Higher levels of education, employment (in-service status), marriage, and urban residence were protective factors for survival among patients with schizophrenia. CONCLUSION: In China, the SMR of schizophrenia is relatively high, and physical diseases are the main cause of death. We suggest that a variety of measures should be taken early to treat somatic diseases and reduce SMR in patients with schizophrenia.
