Abstract:
Objective:To investigate the mortality and life lost among patients with severe mental illness (SMI) that were registered in Ningbo City from 2016 to 2020, so as to provide the evidence for formulating the SMI control strategy.
Methods:All data pertaining to dead SMI patients registered in Ningbo City from 2016 to 2020 were extracted from Ningbo Municipal Mental Health Information Management System. The demographic characteristics and causes of death were analyzed among dead SMI patients, and the life lost was analyzed among dead SMI patients using years of potential life lost (YPLL), years of potential life lost rate (YPLLR) and average years of life lost (AYLL).
Results:A total of 3 350 deaths occurred among SMI patients registered in Ningbo City from 2016 to 2020, with mortality of 1 962/105, including 2 490 patients with schizophrenia (74.33%), 1 640 men (48.96%), 1 877 farmers (56.03%), and 2 622 patients with an educational level of primary school and below (78.27%). The dead SMI patients had a median age of 66.8 (interquartile range, 20.1) years at death, and median disease course of 25.8 (interquartile range, 26.7) years. The median age at death was 63.7 (interquartile range, 18.5) years among men, which was significantly lower than that (median, 70.0 years; interquartile range, 19.6 years) among women (χ2=132.633, P<0.001). The patients with mental retardation complicated by mental disorders had the longest disease course (median, 40.3 years; interquartile range, 34.1 years) and the lowest age at death (median, 61.4 years; interquartile range, 21.9 years). Physical disease was identified as the predominant cause of death (2 754 cases, 82.21%), and the YPLL, AYLL and YPLLR due to all causes of death were 44 417.32 person-years, 15.61 years and 6.21‰. The AYLL was significantly greater among men than among women (17.33 vs. 13.75 years; χ2=68.254, P<0.001). The YPLL was 30 156.80 person-years among patients with schizophrenia, and the AYLL was 20.87 years among patients with mental retardation complicated by mental disorders.
Conclusions:Physical disease was the main cause of death among SMI patients registered in Ningbo City from 2016 to 2020, which posed a great effect on the lifespan among men and patients with schizophrenia and mental retardation complicated by mental disorders.
