Physician peer assessments for compliance with methadone maintenance treatment guidelines

Introduction: Medical associations and licensing bodies face pressure to implement quality assurance programs, but evidence-based models are lacking. To improve the quality of methadone maintenance treatment
(MMT), the College of Physicians and Surgeons of Ontario, Canada, conducts an innovative quality assurance
program on the basis of peer assessments. Using data from this program, we assessed physician compliance
with MMT guidelines and determined whether physician factors (e.g., training, years of practice), practice type,
practice location, and/or caseload is associated with MMT guideline adherence.
Methods: Secondary analysis of methadone practice assessment data collected by the College of Physicians
and Surgeons of Ontario, Canada. Assessment data from methadone prescribing physicians who completed their
first year of methadone practice were analyzed. We calculated the mean percentage compliance per guideline
per physician and global compliance across all guidelines per physician. Linear regression was used to assess
factors associated with compliance.
Results: Data from 149 physician practices and 1,326 patient charts were analyzed. Compliance across all charts was greater than 90% for most areas of care. Compliance was less than 90% for take-home medication procedures; urine toxicology screening; screening for hepatitis B virus (HBV), hepatitis C virus (HCV), human immunodeficiency virus (HIV), tuberculosis, other sexually transmitted infections, and completion of a psychosocial assessment. Mean global compliance across all charts and guidelines per physician was 94.3% (standard deviation = 7.4%) with a range of 70% to 100%. Linear regression analysis revealed that only year of medical school graduation was a significant predictor of physician compliance.
Discussion: This is the first report of MMT peer assessments in Canada. Compliance is high. Few countries
conduct similar assessment processes; none report physician-level results. We cannot quantify the contribution
of peer assessment, training, or self-selection to the compliance rates, but compared to other areas of practice
these rates suggest that peer assessment may exert a significant effect on compliance. A similar assessment
process may in other areas of clinical practice improve physician compliance.
Lessons for Practice
- Quality assurance programs for methadone maintenance programs using chart review, interview, and survey data are important and may lead to high levels of compliance with methadone maintenance treatment guidelines.
- Peer assessment may, in other domains of clinical practice, represent an intervention to improve compliance and is worthy of consideration and further study.
