Circumstances surrounding alcohol toxicity deaths and prior pharmacotherapy for alcohol use disorder in Ontario, Canada.
Introduction: Despite a high prevalence of alcohol use disorder (AUD) in Canada, access to medication-based treatment remains poor. Therefore, our aim was to explore patterns of alcohol toxicity deaths in Ontario, Canada, circumstances surrounding death, prior healthcare interactions, and pharmacotherapy for AUD.
Methods: We conducted a population-based repeated cross-sectional study of alcohol toxicity deaths occurring between 1 January 2018 and 30 June 2022 in Ontario, Canada. We reported trends in deaths over time and determined demographic characteristics of decedents, circumstances surrounding death, and prior healthcare interactions. Among a subset of the cohort with an AUD diagnosis eligible for public drug benefits, we reported receipt of medications used to treat AUD before death.
Results: We identified 1346 alcohol toxicity deaths over the study period, at a median age of 42 years, with 73.8% occurring among men. The majority of alcohol toxicity deaths involved other substances, including opioids (75.2%), benzodiazepines (10.8%), and/or stimulants (45.2%). Half had an AUD (50.4%) and 62.7% had an opioid, benzodiazepine or stimulant use disorder. Among decedents who were public drug beneficiaries with an AUD (N = 361), only 3.6% were actively prescribed first-line AUD pharmacotherapies (naltrexone and/or acamprosate) at time of death.
Conclusions: We found that the majority of alcohol toxicity deaths in Ontario involved other non-alcohol substances. We also detected a high prevalence of prior healthcare encounters for substance use disorders (SUDs) and low prevalence of evidence-based AUD pharmacotherapy. This suggests a need for integrated treatment across concurrent SUDs and improved access to pharmacotherapies for AUD across Ontario.

About the Journal
Alcohol and Alcoholism publishes papers on the biomedical, psychological, and sociological aspects of alcoholism and alcohol research, provided that they make a new and significant contribution to knowledge in the field.
Papers include new results obtained experimentally, descriptions of new experimental (including clinical) methods of importance to the field of alcohol research and treatment, or new interpretations of existing results.
Theoretical contributions are considered equally with papers dealing with experimental work provided that such theoretical contributions are not of a largely speculative or philosophical nature.
