[Interrupted Time Series Analysis for Influence on HIV Related Fatality of Implementation of 'Four Free Services One Care' Policy in China]

To analyze influence on HIV related fatality of implementation of 'Four Free Services One Care' policy in China during 1993-2012, and evaluate effectiveness for the policy of HIV/AIDS prevention and treatment. The data during 1993-2003 (before the implementation of the policy) and during 2005-2012 (after the implementation of the policy) were collected from the national HIV/AIDS Comprehensive Response Information Management System for the analysis on HIV related fatality in Chinese, especially in rural residents. Interrupted time series analysis was used to analyze the trends of HIV related fatality during 1993 and 2012. During the twenty years from 1993 to 2012, the HIV related fatality in China decreased, and the HIV related fatality in rural areas was higher than the overall HIV related fatality. Compared with the period before the implementation of the policy, the overall HIV related fatality decreased by 1.5 (=0.156) and the HIV related fatality in rural residents decreased by 2.6 in 2004 when the policy was implemented (=0.094). As for the change of slope, the overall slope rate after the policy implementation was -0.466 (=0.005), indicating a decrease trend of HIV related fatality. The slope rate after the policy implementation in rural residents was-0.592 (=0.005), indicating a decrease trend of HIV related fatality. At the same time, the slope rate after the policy implementation in rural residents infected through blood transmission route was-0.766 (<0.001), indicating a decrease trend of HIV related fatality. The implementation of the 'Four Free Services One Care' policy in China has made remarkable progress in free HIV antiviral therapy.
