Prevalence and correlates of carrying naloxone among a community-based sample of opioid-using people who inject drugs.

BACKGROUND

Overdose prevention programs are effective at reducing opioid overdose deaths through training people who inject drugs (PWID) how to respond to witnessed overdoses and use naloxone. This report examines prevalence and correlates of carrying naloxone among a community-based sample of PWID.

METHODS

Using respondent driven sampling, PWID (n = 571) in Philadelphia, PA were recruited for the 2015 National HIV Behavioral Surveillance project. The impact of socio-demographics, social services, and law enforcement interaction on naloxone carrying were analyzed using multivariable logistic regression.

RESULTS

Odds of carrying naloxone were higher among PWID who were: homeless (adjusted odds ratio [aOR] = 1.65, 95% confidence interval [CI]: 1.01, 2.83), reported a syringe exchange program as their primary source of syringes (aOR = 2.92, CI: 1.68, 5.09), and had been stopped by police ≥6 times (aOR = 2.16, CI: 1.12, 4.16) or arrested (aOR = 1.84, CI: 1.02, 3.30) in the past year.

CONCLUSIONS

Syringe exchange access was associated with naloxone carrying and is likely a primary source for naloxone and overdose reversal training for PWID. Homelessness and law enforcement encounters are known barriers to harm reducing behaviors; however, both were positively associated with carrying naloxone in this sample. Larger studies are needed to explore these relationships in greater depth.
