BackgroundEmergency department (ED) visits for unintentional opioid overdoses have increased dramatically. Naloxone hydrochloride (Narcan®) is an opioid antagonist commonly used to treat these overdoses.ObjectiveThis study was undertaken to identify experiences regarding naloxone use among ED patients with opioid overdose.MethodsThis prospective survey study was conducted at an urban level I trauma center. A survey was administered to eligible ED patients after unintentional opioid overdose. This study identified current and previous use of naloxone among ED patients with opioid overdose.ResultsEight-nine ED patients with accidental overdose of opioids participated (90% participation rate). Most participants reported a history of opioid overdose (n = 62 [70%]). A significant minority stated they have had access to a naloxone kit (n = 28 [31%]). Most participants with a naloxone kit stated that their frequency and dosage of opiate use did not change after access to naloxone (n = 17 [63%]), and a few used opiates more often (n = 1 [4%]) or less often (n = 9 [33%]). There was a significant negative correlation between total dose and age (Spearman ρ -0.27; p = 0.01). There was no association between dose and sex.ConclusionsMany patients presenting with opioid overdose have had a history of opioid overdose. Patients with opioid overdose required a highly variable dose of naloxone. Higher doses of naloxone were associated with lower age. Despite widespread availability of naloxone to consumers, a minority of patients in this study reported access to naloxone. Participants who had access to a naloxone kit stated that their frequency and dosage of opioid use did not change.Copyright © 2018 Elsevier Inc. All rights reserved.
