AIMS: To investigate the incidence of dropout and the prevalence of poor adherence among newly admitted first-time clients of methadone maintenance treatment (MMT) clinics, and the associations between MMT-related misconceptions and these two treatment outcomes.
DESIGN: A cohort study (maximum follow-up period = 17.6 months) was conducted.
SETTING: Three of the nine MMT clinics in Guangzhou, China participated in the study.
PARTICIPANTS: The sample included 158 newly admitted first-time MMT clients.
MEASUREMENTS: Information collected included background characteristics, history of drug use, MMT-related misconceptions, dropout during the entire study period and poor adherence within the first 6 months since admission to MMT.
FINDINGS: Of all newly admitted MMT clients, 98.2% possessed at least one and 50.6% possessed all four types of MMT-related misconception; 51.3% had dropped out before the completion of the study [95% confidence interval (CI): 43.5-59.1%] and 62% exhibited poor adherence within the first 6 months since admission (95% CI: 54.2-69.6%). Adjusting for significant background variables, the number of misconceived responses predicted significantly both dropout [hazard ratio (HR) = 3.80 for two to three misconceived items, HR = 7.13 for four misconceived items, with zero to one misconceived item being the reference] and poor adherence within the first 6 months [relative risk (RR) = 4.13 for two to three misconceived items; RR = 4.40 for four misconceived items, with zero to one misconceived item being the reference.
CONCLUSIONS: Among opiate addicts in China prescribed methadone maintenance therapy for the first time, misconceptions about this medication are prevalent and are associated with poor adherence to the medication regimen and a high a rate of dropout from the treatment programme.
