Background: The Veteran Health Administration prioritizes the distribution of naloxone to veterans diagnosed with opioid use disorder (OUD) to prevent deaths due to opioid-related overdose. The Overdose Education and Naloxone Distribution (OEND) program was created with tools to supplement efforts in identifying veterans at risk of opioid-related adverse events secondary to OUD or other comorbidities and increase access, education, and distribution of naloxone. Utilizing the OEND tool, Veteran Health Indiana (VHI) employed two different distribution initiatives to increase access to naloxone.
Objective: The purpose of this study is to assess naloxone distribution efforts at a VA medical center and evaluate outcomes in patients who experienced opioid overdose events before and after the OEND initiatives were implemented. The primary outcome is to assess the distribution of naloxone within the year prior to the documented overdose event before and after the OEND initiatives. Secondary outcomes include assessment of the number of naloxone doses administered during the overdose event, substances involved in the overdose, and distribution of outpatient naloxone prescriptions after the overdose event.
Methods: This study was a retrospective electronic chart review of all patients who experienced an opioid-related overdose event at VHI from March 1, 2019, to March 1, 2022.
Results: Of the 59 opioid-overdose events analyzed, the percentage of patients with a naloxone prescription within 12 months prior to an opioid-overdose event was similar between the pre- and post-OEND initiatives. Within 12 months following the overdose event, naloxone was dispensed to nearly 10% more patients in the post-OEND group compared to the pre-OEND group.
Conclusions: The OEND initiatives increased naloxone distribution amongst patients who ultimately experienced an opioid-related overdose. Additional research is needed to assess if these efforts prevented further overdoses.
