Overdose education and naloxone distribution for veterans with opioid use disorder: Results from a pilot initiative.

Patients with opioid use disorder are at a high risk of overdose. To minimize that risk, a program offering intranasal naloxone rescue kits was piloted at a Veterans Administration Hospital. The purpose of this study was to characterize veterans who accepted these potentially lifesaving kits. Retrospective medical chart review of 158 veterans with opioid use disorder receiving treatment on either the inpatient psychiatry detoxification units or outpatient methadone maintenance setting who were offered overdose education and naloxone rescue kits. One hundred and ten of 158 veterans (70%) accepted overdose education and naloxone rescue. Overall, they had a mean age of 39.1 years and averaged 12.7 years of opioid use. In the prior month, they averaged 14.3 days of heroin use; they used alone 48.5% of the time. They estimated an average of 2.8 accidental overdoses over their lifetimes. There were few significant differences between those who accepted and those who declined with regard to demographic and clinical variables. However, significantly higher percentages of outpatients accepted overdose education and naloxone rescue compared to inpatients (89% versus 63%, p = 0.003, Chi-square); the odds of acceptance were increased four-fold when offered to outpatients. Outpatients were nearly a decade older, with more years of opioid use (19.0 versus 11.0), but with less utilization of inpatient services in the prior year (all p < 0.05). The main finding was that 70% of veterans accepted overdose education and naloxone rescue, but significantly higher proportions of outpatients were more receptive than inpatients (89% versus 63%, p = 0.003). Efforts to increase overdose education and naloxone rescue acceptance in all settings are encouraged.
