Objective：To analyze current situation of human immunodeficiency virus(HIV)-infected injecting drug users after 10 years of the implementation of methadone maintenance treatment(MMT). Methods: Data of HIV-infected cases and patients who received MMT were downloaded from HIV/AIDS reporting system to analyze current situation of MMT for HIV-infected cases. Results: A total of 430 HIV infected cases reported by medical establishments in Jiangsu had never got service from MMT clinics. One hundred and ninety HIV infected cases had been accepted by MMT clinics, and 31.58% of them persisted by 2015. Compared with those outside MMT clinics, HIV infected cases in MMT were older(P<0.001), with longer HIV antibody positive status (P<0.001), higher proportion of Han ethnicity(P<0.001), and higher education level(P<0.001). Conclusion: Outpatient coverage of MMT should be enlarged, so that more HIV-infected drug users could get convenient service. Comprehensive intervention measures are recommended to improve the service quality of MMT clinics.
