The 2022 NEMSIS Public-Release Research Dataset includes 51,379,493 EMS activations submitted by 13,946 EMS agencies serving 54 states and territories during the 2022 calendar year.

The dataset does not contain information that identifies patients, EMS agencies, receiving hospitals, or reporting states. EMS events submitted by states to NEMSIS do not necessarily represent all EMS events occurring within a state. In addition, states may vary in criteria used to determine the types of EMS events submitted to the NEMSIS dataset.
