Statewide Prehospital Buprenorphine in Delaware: Two-Years of Paramedic-Initiated Medication for Opioid Use Disorder After Overdose.
Delaware Journal of Public Health · 2025-09-01 · Observational study
Abstract
The Delaware Division of Public Health, Office of Emergency Medical Services (EMS) implemented the first statewide program enabling paramedics throughout the state to initiate buprenorphine treatment for opioid use disorder (OUD) in the prehospital setting. Building on a model from Camden, New Jersey, this protocol was approved in 2022 in response to rising overdose deaths and was fully implemented across Delaware's advanced life support (ALS) EMS agencies in April 2023. Eligible patients-those 18 years or older, resuscitated with naloxone, and able to consent-received up to 24 mg of sublingual buprenorphine along with ondansetron for nausea. Between April 2023 and May 2025, paramedics administered 118 buprenorphine doses to 105 patients, with improvement in withdrawal symptoms reported after 63.6% of doses. Despite a rise in patient ineligibility due to altered mental status-likely linked to sedating adulterants,such as xylazine and medetomidine,in regional street drugs-paramedics increased the percentage of eligible patients accepting offered buprenorphine from 19.0% to 22.8% between the first and second year of the program. This protocol not only addresses acute overdose management in the field but also connects patients to ongoing care, aiming to reduce mortality and expand access to medications for opioid use disorder.
