Characterizing Individuals Who Elect and Decline Opioid Overdose Education and Naloxone Distribution to Tailor Programs and Expand Impact.

Background: In response to the opioid epidemic, federal agencies have stressed the importance of targeted naloxone distribution through avenues such as Opioid Overdose Education and Naloxone Distribution (OEND). OEND effectively reduces mortality by training laypersons to respond to overdose situations. Despite demonstrated effectiveness, OEND remains underutilized. This project aimed to characterize those who illicitly use opioids to determine avenues for future tailoring of OEND programs.
Methods: Individuals who illicitly used opioids within the past 6 months were recruited via online social media. Participants completed an online questionnaire that assessed history of opioid use and were given the option to receive opioid overdose and naloxone administration training. Those who elected training (n = 111) and those who declined (n = 193) were compared on opioid use, severity of use, and overdose experiences.
Results: Participants (N = 304) were 47% male and 83% White. Tests of between group differences with measures of effect size were used for analyses. Those who elected training endorsed greater intravenous administration (χ2 = 4.18, P = 0.041, Cramer's V = 0.12). Individuals who declined training reported more frequent nonprescribed methadone use (χ2 = 7.51, P = 0.006, Cramer's V = 0.16), overdose hospitalizations (t(298) = 2.13, P = 0.034, Cohen's d = 0.26), and observed overdoses (t(300) = 3.01, P = 0.003, Cohen's d = 0.36). After adjusting for multiple comparisons, only the differences in nonprescribed methadone use and observed overdoses remained statistically significant.
Conclusions: Individuals who declined training were more likely to report ever use of nonprescribed methadone and having witnessed others overdose. They may have had greater exposure to naloxone, hence decreasing perceived need for training. Understanding characteristics of those who elect and refuse training could inform structuring of programs and recruitment approaches.
