Multiple Naloxone Administrations Among Emergency Medical Service Providers is Increasing

AbstractBackground: Opioid overdoses are at epidemic levels in the United States. Emergency Medical Service (EMS) providers may administer naloxone to restore patient breathing and prevent respiratory arrest. There was a need for contemporary data to examine the number of naloxone administrations in an EMS encounter. Methods: Using data from the National Emergency Medical Services Information System, we examined data from 2012–5 to determine trends in patients receiving multiple naloxone administrations (MNAs).

The percentage of patients receiving MNA increased from 14.5% in 2012 to 18.2% in 2015, which represents a 26% increase in MNA in 4 years. Patients aged 20–29 had the highest percentage of MNA (21.1%)....
