Objectives: Efforts to improve low naloxone uptake to mitigate the current opioid crisis have included coprescribing naloxone with opioid medications and, more recently, expansion through over-the-counter availability, the latter of which necessitates self-identification of overdose risk by consumers. This study sought to understand perceptions of opioid overdose risk and naloxone among distinct opioid populations at elevated risk for overdose.
Methods: A cross-sectional, online survey was provided to 2 opioid populations in June 2020. First, chronic pain opioid managed (CPOM; n = 190) individuals currently treated with an opioid prescription (either >50 daily morphine milligram equivalents [73.2%] or benzodiazepine co-use [52.6%]), restricted by confounders. Second, individuals with a history of opioid use disorder (OUD; n = 152) previously participating in a national opioid surveillance study of new entrants to substance use treatment centers.
Results: Risk perceptions significantly differed, with 60.0% (CPOM) versus 28.9% (OUD) reporting that they were "not at all concerned about overdosing," and 62.1% (CPOM) versus 19.1% (OUD) perceiving themselves as having "no risk" of overdose. Perceived need for naloxone was lower among CPOM versus OUD patients (48.3% and 71.8%, respectively), whereas 22.6% and 35.0%, respectively, indicated any likelihood of obtaining naloxone in the future.
Conclusions: Results suggest that a significant proportion of both samples lacked the ability to self-identify their risk of overdose and self-select themselves as needing naloxone, with gaps being more prominent in the CPOM sample. A multi-intervention framework that addresses distinct pathways of behavioral change between unique opioid populations should be considered in conversations surrounding potential transitions to over-the-counter naloxone.
