BackgroundIncreasing the equitable distribution of take home naloxone (THN) may result in reduced deaths from opioid overdose (OD).ObjectivesThe primary study objective is to describe the demographic and clinical characteristics of emergency department (ED) patients who decline THN. The findings of this descriptive study may generate new hypotheses for successful THN distribution.MethodsRetrospective chart review using prospectively collected program evaluation data from a single urban EDs Health Education THN database and electronic health record. Characteristics of participants who refused versus accepted THN were compared using Chi-square testing for categorical variables and t-tests for continuous variables. A multivariate model was built to assess associations of statistical and clinically relevant characteristics with THN refusal.ResultsA total of 711 ED patients were offered THN of which 334 (46%) declined. In unadjusted analysis, with the independent variable being refusal of the THN offer, being currently on medication for opioid use disorder (MOUD) was associated with a greater odds of refusal (OR 1.9, 95%CI 1.3-2.6) while any drug related overdose (OR 0.6, 95%CI 0.4-0.8) or being given a prescription for buprenorphine in the ED (OR 0.2, 95%CI 0.1-0.9) were both associated with a lower odds of refusal.ConclusionsDemographic characteristics did not differ between those who accept versus refuse THN. Patients already receiving MOUD were more likely to refuse THN while those starting MOUD in the ED were less likely to refuse THN. Further studies are needed to determine the root causes of patients' declination of THN and develop targeted interventions to address these causes.Copyright © 2024. Published by Elsevier Inc.
