Introduction: Emergency departments (EDs) are often the first point of care for people at risk of opioid-related overdose, an issue on the rise in Canada. Dispensing take-home naloxone (THN) and/or initiating opioid agonist treatment (OAT) in the ED can help prevent overdose.

Methods: The SuboxED (CC-BY-NC-SA) project evaluated the implementation of a clinical algorithm for dispensing THN and prescribing buprenorphine/naloxone (B/n) in three EDs in the province of Québec. We performed a retrospective review of ED electronic medical records flagged as “at risk of opioid overdose (ROO).” This study included an implementation process from April 1, 2018 to April 30, 2019, and an evaluation of the project implementation for eligible patients from May 1 to December 31, 2019. We also administered satisfaction surveys to medical teams and patients.

Results: A total of 877 (36.2%) patient records were included in the analysis. Of these, 62% had a confirmed diagnostic of opioid use disorder (OUD) and 70.8% met eligibility criteria for naloxone prescription. However, only 7.7 % were given a prescription or take-home naloxone in the ED, and 12.4 % were initiated on B/n in the ED or in the community after the ED visit. Seven patients and 125 health care providers from EDs, clinics, and retail pharmacies completed the survey.

Conclusion: The SuboxED project demonstrated the feasibility of implementing a clinical algorithm for dispensing THN and initiating B/n in the ED, and of evaluating its efficacy in the 6 months following implantation. In addition to advocating for free access to THN in EDs, scaling up the uptake of the algorithm in EDs is the next challenge.
