WASHINGTON — The National Emergency Medical Services Information System Technical Assistance Center has released the 2021 Public-Release Research Dataset, the largest publicly available data of emergency medical services activations in the U.S.

For the first time, data from Delaware is included. With the addition, EMS data from all 50 states plus three U.S. territories are in the data set.

According to a news release from the NHTSA EMS, “The dataset includes information from patient care reports from nearly 49 million EMS activations submitted by almost 14,000 EMS agencies serving communities across the country. Collected at the local level by individual EMS clinicians responding to calls and caring for patients, this data provides EMS agencies, states and the nation with critical insights for quality improvement, resource deployment, public health surveillance and more.”

Researchers use the data to study operational and clinical issues.

The NEMSIS data standard and National EMS Database were created with support from the National Highway Traffic Safety Administration Office of EMS.
