Abstract:
Objective:To analyze the survival status and death factors of confirmed HIV-infected patients in Hangzhou to provide a basis for the formulation of AIDS prevention and treatment strategies.Methods:A retrospective cohort study was conducted. The data were from the HIV/AIDS Comprehensive Response Information Management System of the Chinese Disease Control and Prevention Information System.Epidemiological characteristics of HIV-infected patients were comparied in Hangzhou City from 2004 to 2023 by using chi-square Test. The survival rate of HIV-infected patients in Hangzhou was calculated by the life table method, the survival curves of different subgroups were described by the Kaplan-Meier method, and the Cox proportional hazard regression model was used to analyze the influencing factors of death risk. The SPSS 26.0 software was used for statistical analysis.Results:Among the 9 457 subjects, the total follow-up time was 58 004.18 person-years, 494 patients died, fatality rate of all-cause cases was 0.85 per 100 person-years.The average survival time was 18.59 (95% CI:18.40-18.78) years. Malignant neoplasms and pneumocystis pneumonia were the first (14.37%,71/494) and second (10.73%, 53/494) causes of death, respectively. Death within 6 months after diagnosis accounted for 42.51% (210/494), and suicide accounted for 4.25% (21/494). Multivariate Cox regression analysis showed that compared with those who received antiviral treatment (ART) within 3 months of diagnosis, those who received ART outside 3 months and those who did not receive ART had a 1.65 (95% CI:1.25-2.19) and 20.68 (95% CI:15.80-27.06) times risk of death, respectively. The HIV-infected patients with high CD4 +T lymphocytes (CD4) counts for the first time had a lower risk of death. The risk of death of patients with baseline CD4 counts of 200-349 cells/μl, 350-499 cells/μl, and ≥500 cells/μl was 0.38 (95% CI:0.29-0.49), 0.26 (95% CI:0.19-0.36), 0.21 (95% CI:0.14-0.31) times higher than that of baseline CD4 counts <200 cells/μl, respectively. Conclusions:The overall survival of the HIV-infected patients was good in Hangzhou from 2004 to 2023. Early detection of HIV infection and timely mobilization to participate in ART was the key to improving the survival rate of patients. At the same time, given the suicide problem of HIV-infected patients, suicide surveillance and depression and anxiety screening of HIV-infected patients should be further strengthened, and targeted psychological intervention policies should be implemented.
