Abstract

Introduction: Patients with opioid use disorder (OUD) are at increased risk for overdose and death. Clinical practice guidelines and professional organization policy statements recommend providing naloxone to patients at risk for overdose. We sought to characterize fidelity to naloxone practice recommendations in a cohort of Emergency Department (ED) patients in whom opioid use disorder was suspected by the treating physician. Methods: This single-center cross-sectional study evaluated electronic health records from an urban academic ED with 73,000 annual encounters in a region with a high prevalence of OUD. Patients ≥18 years old with encounters from January 1, 2018 to November 30, 2019 were included if discharged from the ED and either administered buprenorphine in the ED or referred to outpatient substance use treatment. The primary outcome measure was the percentage of included patients provided naloxone (take-home or prescription). We used random effects multivariable logistic regression (accounting for multiple patient encounters) to estimate the odds ratio (OR) for receiving naloxone. Results: Of 1036 eligible patient encounters, 320 resulted in naloxone provision (30.9%, 95% CI: 28.1–33.8). Naloxone provision occurred for 33.6% (95% CI 30.5–36.7) of 900 patients referred to outpatient substance use treatment without ED buprenorphine administration, 10.6% (95% CI 5.0–19.2) of 85 patients administered buprenorphine and not referred to outpatient substance use treatment, and 17.6% (95% CI 8.4–30.9) of 51 patients administered buprenorphine and referred to outpatient treatment. After controlling for age, sex, race, and prior provision of naloxone, the administration of buprenorphine was associated with a 94% lower odds (aOR = 0.06 [95% CI 0.011–0.33]) for naloxone provision compared to those only referred to outpatient treatment. Conclusion: A majority of ED patients who received an intervention targeted at OUD, in an ED where take-home naloxone is freely available, did not receive either take-home naloxone or a prescription for naloxone at discharge. Patients receiving buprenorphine were less likely to receive naloxone than patients only referred to outpatient treatment. These data suggest barriers other than recognition of potential OUD and naloxone availability impact provision of naloxone and argue for a treatment “bundle” as a conceptual model for care of ED patients with suspected OUD.
