Introduction: Emergency Department (ED) visits related to substance use are rapidly increasing. Despite this, few Canadian EDs have immediate access to addiction medicine specialists or on-site addiction medicine clinics. This study characterized substance-related ED presentations to an urban tertiary care ED and assessed need for an on-site rapid-access addiction clinic (RAAC). Methods: This prospective enrollment, retrospective chart review was conducted from June to August 2018. Adult patients presenting to the ED with a known or suspected substance use disorder were enrolled by any member of their ED care team using a 1-page form. Retrospective chart review of the index ED visit was conducted and the Emergency Department Information System was used to extract information related to the visit. A multivariable logistic regression model was fit to examine factors associated with recommendation for referral to a hypothetical on-site RAAC.This prospective enrollment, retrospective chart review was conducted from June to August 2018. Adult patients presenting to the ED with a known or suspected substance use disorder were enrolled by any member of their ED care team using a 1-page form. Retrospective chart review of the index ED visit was conducted and the Emergency Department Information System was used to extract information related to the visit. A multivariable logistic regression model was fit to examine factors associated with recommendation for referral to a hypothetical on-site RAAC. Results: Of the 557 enrolment forms received, 458 were included in the analysis. 64% of included patients were male and 36% were female, with a median age of 35.0 years. Polysubstance use was seen in 23% of patients, and alcohol was the most common substance indicated (60%), followed by stimulants (32%) and opioids (16%). The median ED length of stay for included patients was 483 minutes, compared to 354 minutes for all-comers discharged from the ED during the study period. 28% of patients had a previous ED visit within 7 days of the index visit, and an additional 17% had a visit in the preceding 30 days. The ED care team indicated ‘Yes’ for RAAC referral from the ED for 66% of patients, for a mean of 4.3 patients referred per day during the study period. Multivariable analysis showed that all substances (except cannabis) correlated to a statistically significant increase in likelihood for indicating ‘Yes’ for RAAC referral from the ED (alcohol, stimulants, opioids, polysubstance; p < 0.05). Patients presenting to the ED with a chief complaint related to substance use were also more likely to be referred (p = 0.01). Conclusion: This retrospective chart review characterized substance-related presentations at a Canadian urban tertiary care ED. Approximately four patients per day would have been referred to an on-site RAAC had one been available. The RAAC model has been implemented in other Canadian hospitals, and collaborating with these sites to begin developing this service would be an important next step.

Introduction: Emergency department visits related to substance use are becoming more serious and increasingly costly in Canada. Emergency physicians must be able to effectively screen, manage, refer, and advocate for these complex patients. This study sought to describe the current state of addiction medicine training in Canadian emergency medicine (EM) residency programs and to assess the need for a formal curriculum. Methods: All Royal College and College of Family Physicians EM Program Directors (PDs) were asked to participate in a ten-question needs assessment survey on addiction medicine training for residents. Questions were developed through consensus after reviewing the relevant literature and conducting a formal pilot survey with staff physicians experienced in survey methodology. Responses were collected securely using the Research Electronic Data Capture (REDCap) database. Results: 19 out of 31 (62%) eligible PDs completed the survey. The importance of addiction medicine training received a median score of 69.5 (IQR=74.0) on a scale of 1-100. Most programs devoted two hours or less per year of formalized teaching on individual topics (such as opioids, alcohol, harm reduction) over the past two academic years. The two most common teaching modalities used were didactic lectures (15/19, 78.9%) and case-based tutorials (12/19, 63.2%). Case-based tutorials were identified as the most effective teaching method (12/19, 63.2%). Topics highlighted as most important to include in a curriculum were: screening for substance use disorders and referral for further treatment (14/19, 73.7%), social determinants of health (14/19, 73.7%), alcohol, opioid, and stimulant intoxication and/or withdrawal (14/19, 73.7% each), and management of patients on opioid agonist therapy (14/19, 73.7%). The most commonly perceived barriers to implementing such a curriculum were insufficient curriculum time (10/19, 52.6%) and lack of qualified teaching staff (7/19, 36.8%). Conclusion: This needs assessment provides an understanding of the current state of addiction medicine training for EM residents in Canada. A case-based addiction medicine workshop is currently being developed to address identified curriculum gaps. Integrating this curriculum longitudinally into a time-constrained academic schedule is an important next step.

Introduction: 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 under-utilized 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.
