[Effectiveness of the "Internet Plus-based AIDS Comprehensive Prevention Service System" among MSM in Guangzhou]

Objective: To evaluate the effectiveness of the "Internet Plus-based AIDS Comprehensive Prevention Service System" among men who have sex with men in Guangzhou. Methods: Data through case-reporting and follow-up programs on MSM HIV/AIDS in Guangzhou was collected from the China Information System for Disease Control and Prevention, which including those from the referral and follow-up treatment compliance programs in 2008-2014 (pre-treatment) and 2017-2018 (post-treatment). According to the types of care services, three groups were set as: with "Internet Plus" service, with 'HIV counseling/testing service' or with 'routine medical service'. General Estimating Equation (GEE) was used to analyze the follow up situation of HIV/AIDS cases, annually. Cox proportional hazard regression model was used to analyze the proportions of treatment referral, within the 30 days of diagnosis. Results: Before the implementation of immediate treatment after HIV diagnosis, 90.6% (707/780) of the HIV/AIDS cases received the first follow up program including the CD(4)(+) T cells counts (CD(4)) test service within 90 days of diagnosis, in the "Internet Plus-based HIV/AIDS care service" group presented 1.19 times (95%CI: 1.14-1.25) of the routine medical service group. The implementation of immediate treatment after HIV diagnosis, compared with the routine medical service group, the "Internet Plus" service group presented 1.71 times (95%CI: 1.03- 2.83) more treatment referrals within the 30 days of diagnosis, when the first testing CD(4) was ≤200 cells/μl. Compared with the routine medical service group, the HIV counseling and testing service group showed 1.37 times (95%CI: 1.20-1.56) more of the treatment referrals within the 30 days of HIV diagnosis, after the first testing CD(4) counts as >200 cells/μl. Conclusion: Standardized care and follow-up service should be promoted as soon as the referral and treatment programs were set after the diagnosis was made, under the "Internet Plus-based AIDS Comprehensive Prevention Service System" for the MSM population, in Guangzhou.
