Differences in Self-identification of Opioid Overdose Risk and Naloxone Perceptions Between Therapeutic and Nontherapeutic Opioid Populations.

Abstract

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. 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. 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. 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.
