First-line medications for alcohol use disorders among public drug plan beneficiaries in Ontario.

OBJECTIVE: To examine use of first-line alcohol use disorder (AUD) medications (naltrexone and acamprosate) among public drug plan beneficiaries in the year following an AUD diagnosis.
DESIGN: Retrospective population-based cohort study.
SETTING: Ontario. PARTICIPANTS: Individuals eligible for public drug plan benefits who had an AUD diagnosis at a hospital visit between April 1, 2011, and March 31, 2012. MAIN OUTCOME MEASURES: Number of AUD medications dispensed to public drug plan beneficiaries who had a recent hospital visit with an AUD diagnosis, and number of prescriptions dispensed per person.
RESULTS: A total of 10 394 Ontarians between 18 and 65 years of age were identified who had a hospital visit with an AUD diagnosis and were eligible for public drug plan benefits. The rate of AUD medications dispensed in the subsequent year was 3.56 per 1000 population (95% CI 2.51 to 4.91; n = 37). This rate did not differ significantly by sex (P = .83).
CONCLUSION: Very few public drug plan beneficiaries are dispensed first-line AUD medications in the year following an AUD diagnosis. Copyright© the College of Family Physicians of Canada.
