2020 Mid-Year Public-Release Research Dataset

The 2020 Mid-Year Public-Release Research Dataset is a subset of the National EMS Database that is the repository for EMS data collected from U.S. States and Territories. NEMSIS is a national standard for how patient care information resulting from an emergency 9-1-1 call for assistance is collected. The dataset includes 19,749,812 EMS activations submitted by 10,620 EMS agencies servicing 47 states and territories. This mid-year release is provided due to overwhelming requests from researchers interested in investigating EMS response during the Spring outbreak of COVID-19. The dataset does not contain information that identifies patients, EMS agencies, receiving hospitals, or reporting states. Click for more information on how to access the dataset.
