Association Between User Fees and Dropout from Methadone Maintenance Therapy: Results of a Cohort Study in Vietnam
Abstract—Vietnam launched methadone maintenance therapy (MMT) in 2008 with donor funding. To expand and ensure sustainability of the program, Vietnam shifted the responsibility for financing portions of MMT to provinces and, in 2015, some provinces started collecting user fees for MMT. This study assesses the association between user fees and patient dropout using a one-year observational cohort of 1,021 MMT patients in which three of seven provinces included in the study implemented user fees. We also estimate the catastrophic payments—payments of 40% or more of nonsubsistence expenditures—associated with MMT. Box-Cox proportional hazard models were used to assess the association between user fees and patient dropout. About 85% of the cohort was actively on MMT at the end of the observation period. Of those who stopped MMT care, about 8% dropped out, 3.5% were incarcerated, 1.5% died, and 2% stopped for other reasons. The dropout hazard ratio for paying user fees compared to not paying user fees ranged from 0.70 (unadjusted, p = 0.26) to 0.29 (adjusted, p = 0.33). However, 29% of patients in provinces implementing user fees incurred catastrophic payments for MMT associated user fees and transportation, compared with 11% of patients in provinces not implementing user fees (p < 0.001). In one year of follow-up, we do not find evidence that user fees increased dropout from MMT. However, catastrophic payment rates remain a concern. This study represents an example of one type of monitoring of financial transitions; further and longer-term evaluation of user fees is needed.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
