Abstract:Abstract: OBJECTIVE To analyze the current status and trends in the management and treatment of patients with severe mental disorders in Tianjin from 2020 to 2024,providing scientific evidence for future mental health policy formulation and service optimization.METHODS Relevant data from 2020 to 2024 were extracted from the Tianjin Mental Health Information System. Demographic characteristics,reported prevalence rates,regular medication adherence rates,and standardized management rates among patients with severe mental disorders were analyzed.RESULTS From 2020 to 2024,the proportion of female patients increased from 49.19%to 50.33%,the proportion of patients aged 60 years and older increased from 29.29%to 38.61%,and the proportion of patients with higher education(college degree or above)rose from 6.65%to 8.76%.Reported prevalence increased from 3.67 %o to 4.19‰,standardized management rates rose from 89.90%to 95.20%,regular medication adherence rates climbed from 79.98%to 92.60%,face-to-face visit rates increased from 90.60%to 95.25%,and physical examination rates rose from 52.67%to 80.03%. The reported prevalence rate,standardized management rate,medication adherence rate,face-to-face visit rate,and physical examination rate all showed a linear upward trend over the years(x²=392.84,1,875.23,5,780.83,1,603.74,8,076.10;P< 0.01).CONCLUSION From 2020 to 2024,significant changes occured in the demographic characteristics of individuals with severe mental disorders in Tianjin.All management and treatment indicators showed annual increases;however,efforts to screen thefloating population andintervene in medication adherence for specific disorders remain necessary.Future focus should address the service needs of female,elderly,and highly educated patient groups,while further investigating the impact of demographic factors on management and treatment indicators.
