Abstract
Background: Acquired immune deficiency syndrome (AIDS) remains a significant public health concern in China. Treatment coverage has been expanded by revising the antiretroviral therapy (ART) for people living with HIV (PLWH). Several years after implementing the new “Test and Treat” strategy, it is essential to evaluate its impact on people living with HIV since its implementation. Objectives: This study was conducted to comprehensively analyze the deaths of PLWH from 2017 to 2022 in Baise City, China. Methods: A retrospective cohort study was conducted to comprehensively analyze the deaths of PLWH in Baise from 2017 to the first half of 2022. The data was acquired from the AIDS Information System (AIDSIS). The all-cause and AIDS-related mortality rates were calculated for PLWH, along with the proportion of specific death causes. Interrupted time series analysis was utilized to examine changes in all-cause mortality pre- and post-implementation of the new strategy. Kaplan-Meier curves were drawn to compare the mortality risk within 1 year of diagnosis between treated and untreated patients, as well as between late discoverers and non-late discoverers. Related factors of death were also analyzed using the Cox proportional hazards regression model. Results: During the observation period, among a total of 8,922 PLWH cases, 1,265 people died, resulting in an all-cause mortality rate of 4.19 per 100 person-years. Acquired immune deficiency syndrome -related deaths numbered 438, accounting for 34.62% of the total deaths, with a mortality rate of 1.45 per 100 person-years. There were 730 non-AIDS-related deaths, representing 57.71%, with a mortality rate of 2.42 per 100 person-years. The overall mortality rate from all causes within 1 year after diagnosis was 5.58 per 100 person-years. No significant difference was identified in the all-cause mortality rate between the periods before and after the implementation of the new strategy. Untreated PLWH and late discoverers exhibited a high risk of death within 1 year of diagnosis. Most deaths were caused by common chronic diseases, while AIDS-related mortality was mainly due to opportunistic infections. Factors such as gender, age at diagnosis, occupation, educational background, ethnic group, infection route, history of ART, and baseline CD4 level were associated with the risk of all-cause mortality and AIDS-related mortality. Conclusions: After the implementation of the “Test and Treat” strategy, no significant difference in mortality among PLWH was recorded in Baise City, China. We recommend that the health department strengthen the testing of PLWH and improve treatment options. Additionally, we suggest encouraging the maintenance of long-term ART treatment and taking measures to prevent and control tuberculosis and common chronic diseases in individuals who are HIV positive.
