Who uses methadone services in <scp>C</scp>hina? Monitoring the world's largest methadone programme

Abstract

The profile of clients enrolling in methadone maintenance treatment in China is continually changing and appears to be associated with reduced risk of HIV. High dropout in the programme may limit its effectiveness. The availability of a centralized, real-time data system was extremely useful for monitoring the progress of the Chinese methadone maintenance treatment programme.
