Layperson naloxone linked to fewer EMS interventions

Layperson naloxone administration and subsequent emergency medical services care for opioid overdose
Drug and Alcohol Dependence · 2026-10-31 · Added 6 November 2026

In a US cross-sectional study of 26,087 EMS activations for opioid overdose, layperson-administered naloxone (30.7% of cases) was associated with less subsequent EMS naloxone (24.4% vs 34.8%) and lower odds of transport (aOR 0.78).

Study type

Cross-sectional

Design

Cross-sectional analysis of a national EMS registry

Participants

26,087 EMS activations for opioid overdose (adults 16 and over)

Main finding

Layperson naloxone preceded 30.7% of activations; any subsequent EMS naloxone 24.4% vs 34.8% (aOR 0.73, 95% CI 0.68–0.78) and transport 79.4% vs 84.4% (aOR 0.78, 95% CI 0.73–0.84); advanced airway attempts (1.6% vs 1.4%) and cardiac arrest (6.6% vs 6.0%) uncommon in both groups.

Caveat

Registry cross-section — why transports were lower (refusal versus genuine recovery) isn't known.

Bottom line

Supports current practice

Learning goal

Weigh how prehospital naloxone given by bystanders affects my assessment and transport decisions in opioid overdose.
