Abstract:
This repeated cross-sectional analysis uses 2017-2023 National Emergency Medical Services Information System (NEMSIS) data to characterize age-based trends in overdose-related EMS encounters. We calculated the annual rate of opioid overdose-related EMS encounters per 10 000 total EMS encounters across six age-groups. Among all age-groups, the annual rate of opioid overdose-related EMS encounters increased from 2019 to 2020. The largest increase was seen among adolescents under age 18, which increased by 70% (7.7-13.1 per 10 000 EMS encounters). From 2022 to 2023, the annual rate of opioid overdose-related EMS encounters decreased among all age-groups. Among those ages 18-24 and 25-34, overdose-related EMS encounters resemble pre-pandemic levels. In contrast, the annual rate among the under 18 group remained 62% higher (12.5 per 10 000 EMS encounters) than pre-pandemic levels. Given inaccurate beliefs that opioid overdoses only affect adults, system-level interventions are needed to expand access to youth-focused prevention, harm reduction, and treatment services.
