Trends in Suspected Opioid Drug Overdose Events in Emergency Medical Service Encounters in South Carolina, 2019-2022.

Abstract

OBJECTIVES The number of drug overdoses and drug-related deaths has increased across the United States in recent years. Reports of suspected opioid drug overdoses identified through emergency medical services (EMS) are valuable sources of information for shaping the public health response to drug overdoses. The objective of this study was to describe trends in the number of EMS-reported suspected opioid drug overdose events in South Carolina from 2019 through 2022. METHODS We included reports of suspected opioid drug overdoses if they met the definition of nonfatal opioid overdose syndrome in our analysis. We analyzed statewide data reported from EMS agencies to biospatial, Inc, from January 2019 through December 2022 to understand demographic trends for a statewide overdose and response program in South Carolina. RESULTS In 2022, a total of 11 078 suspected opioid drug overdose events, or 216.4 per 100 000 South Carolina residents, were reported by EMS. During the 4-year study period, the number of EMS-reported suspected opioid drug overdoses increased by 82%, with African American people experiencing a 133% increase and White people experiencing a 68% increase. The number of opioid overdoses increased among all age groups during the study period. Approximately 84% of opioid overdoses were reported in urban counties, but rural counties had a higher number of opioid overdose reports per capita than urban counties. CONCLUSIONS Monitoring trends in suspected opioid drug overdoses allows decision makers to adjust resources and programs for overdose response and is essential for local coordinated response. Continued monitoring of trends is needed for an equitable response to prevent opioid drug overdoses.
