    Abstract:
    Methadone maintenance therapy (MMT) is effective in treatment of opiate dependents. However, there is a gap between the coverage of standard MMT clinics and the need of opiate dependents. Establishment of extension clinics of methadone maintenance therapy (EMMT) will increase the coverage and improve MMT accessibility. We implemented a prospective cohort study to understand the effects of establishment of community-based EMMT clinics comparing with MMT clinics in Yunnan Province.A total of 462 opiate-dependent clients were interviewed from the community-based EMMT clinics and standard MMT clinics located in 5 counties of Mangshi, Ruili, Longchuan, Yingjiang, and Lianghe in Yunnan Province. The information on the demographic characteristics, drug risk behaviors, quality of life (QOL), and urine testing results for morphine of the clients was collected and compared between the EMMT and MMT clinics. A survival analysis method was utilized to know the retention situation of the newly enrolled clients with Kaplan-Meier method during 9 months treatment.Among the EMMT clients, 96.9% were male; 31.4% were Han; 61.4% were married; 39.0% had primary school education; 95.5% lived with their family or relatives; 96.9% who arrived the clinic less than 15 min; 52.9% had used drugs for more than 10 years; and 16.7% injected drug. After 9 months therapy, there was no difference in the changes of life quality such as physical and psychological features, social relationships, environmental function, and total QOL and well-being between those of EMMT and MMT clinics. The positive detection rate of urine-morphine testing among newly enrolled clients of EMMT clinics decreased as the period of treatment lengthened. The average time of retention for newly enrolled EMMT clients who are still receiving the treatment was 175 days. And the average time from initiations to drop-out of treatment for newly enrolled EMMT clients was 122 days. The 9-month retention rates of the clients were 52.1% and 60.9% at EMMT and MMT clinics, respectively.The effect on EMMT retention was the same as that of MMT. Establishment of EMMT clinics was an effective strategy to expand the coverage of MMT and increase the retention of opiate dependents in the rural areas of the counties.
