Trends and Regional Variation in Heat-Related EMS Encounters in the US

Listen to this summary

This study investigates trends and regional variations in prehospital heat-related emergency medical service (EMS) encounters in the U.S. from 2019 to 2023, aiming to identify demographic and clinical factors associated with these encounters. The findings reveal a slight overall increase in heat-related encounters by 2023, with significant regional disparities, particularly in the Mountain and West South Central divisions. The authors emphasize the need for further research to understand vulnerabilities and improve emergency response strategies in affected areas.
