National Emergency Medical Services Database
The National EMS Database is provided by the National Emergency Medical Services Information System (NEMSIS) project. The National EMS Database includes patient care information resulting from EMS activations for emergency care and transport in response to a 9-1-1 call for assistance. Every six months, state EMS data managers participate in a survey requesting them to calculate the percent of state licensed EMS agencies that are currently submitting EMS records to the state repository. These state repositories, in turn, submit EMS records to the National EMS Database.
The “currently accepted dataset standard” is defined as the currently accepted NEMSIS Version 3 data standard.

Calculating the number of states submitting 90% of EMS calls to the National EMS Database using the NEMSIS Version 3 dataset standard: Each state EMS office licenses EMS agencies within the state and catalogs each agency service area. Service area size and population demographics for EMS agencies submitting EMS calls are used to estimate the call volume (CV) in service areas of “non-submitting” EMS agencies. Submitted Call Volume/Submitted Call Volume + Estimated Non-Submitted Call Volume = % of EMS calls submitted to NEMSIS. “Submitting EMS calls to the national EMS database” refers to the transmission of records from the state EMS repository to the national EMS database using the existing NEMSIS transmission standard.
In 2014, 47 states submitted information regarding the percent of state licensed EMS agencies providing data to the National EMS Database using the currently accepted NEMSIS data standard.
