Unintentional overdose is the leading cause of injurious death among Americans aged 25-64 years. A similar epidemic is underway in Canada. Community-based opioid overdose education and naloxone distribution (OOEND) programs distribute take-home naloxone kits to people at risk of overdose in several cities across Canada. Due to the high rate of drug-related visits, recurrent opioid prescribing, and routine encounters with opioid overdose, Emergency Departments (ED) may represent an

... setting to deliver naloxone to people at risk of opioid overdose or likely to witness overdose. The goal of this study was to identify Canadian emergency physician attitudes and perceived barriers to the implementation of take-home naloxone programs. Methods: This was an anonymous web-based survey of physician and trainee members of the Canadian Association of Emergency Physicians. Survey questions were developed by the research team and piloted for face validity and clarity. Two reminder emails were sent to non-responders at 2-week intervals, per the modified Dillman method. Respondent demographics were collected and Likert scales used to assess attitudes and barriers to the prescription of naloxone from the ED. Results: A total of 347/1658 CAEP members responded (20.9%). Of the respondents, 62.1% were male and residents made up 15.6%. The majority (48.2%) worked in Ontario and 55.7% worked in an urban tertiary centre. Overall attitudes to OOEND were strongly positive: 86.6% of respondents identified a willingness to prescribe naloxone from the ED. Perceived barriers included allied health support for patient education (56.4%), access to follow-up (40.3%), and inadequate time in the clinical encounter (37.7%). In addition to people at risk of overdose, 78% of respondents identified that friends and family members may benefit from OOEND programs. Conclusion: Canadian emergency physicians are willing to prescribe take-home naloxone to at-risk patients, but better systems and tools are required to facilitate opioid overdose education and naloxone distribution implementation. This data will inform the development of these programs, with emphasis on allied health support, training and education.
