Confidence in providing methadone maintenance treatment of primary care providers in Vietnam

Abstract

Background: Delivering methadone treatment in community health facilities by primary care providers is a task-shifting strategy to expand access to drug use treatment, especially in rural mountainous areas. This study aims to investigate factors related to confidence in providing methadone treatment among primary care providers in Vietnam to inform good practice development. Methods: We conducted a cross-sectional survey with 276 primary care providers who were physicians, physician assistants, nurses, pharmacists or dispensing staff from 67 communes in a mountainous province in Northern Vietnam. Using self-report scales, we measured providers’ confidence in providing methadone treatment, beliefs in harm reduction, perceived work-related support, perceived stigma and risk in working with drug-using patients, and empathy towards this population. We used multiple linear regression analyses to explore factors associated with providers’ confidence in providing methadone treatment in the whole sample and to compare two groups of providers who did and did not have experience providing methadone. Potential associated factors were measured at facility and provider levels. Result: 114 (41.3%) participants had previously experience in providing methadone treatment. Providers with methadone treatment experiences had higher confidence in and more accurate knowledge of methadone treatment, perceived less stigma of working with drug-using patients, and reported more work-related support than those without experiences. Higher medical education is associated with lower confidence in providing methadone treatment among providers without methadone experiences, but higher confidence among providers with methadone experiences. Better methadone knowledge was associated with greater confidence in providing methadone treatment among inexperienced providers but not among those with experiences. Receiving work-related support was associated with greater confidence in providing treatment in both groups, regardless of their past methadone experiences. Conclusion: In rural provinces where methadone treatment has been expanded to primary care clinics, interventions to improve primary care providers’ confidence should benefit professionals with diverse experiences in providing methadone treatment. Continued training and support at work for providers is essential to ensuring quality in decentralized methadone treatment.
