The 2015 NEMSIS Public-Release Research Dataset is available to you
2015 NEMSIS Public-Release Research Dataset includes 30,206,450 EMS activations submitted by 10,137 EMS agencies serving 49 states and territories during the 2015 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.

Much care was taken to ensure that the data are as clean as possible. All data submitted by states must comply with the XML standard and are exposed to several hundred error rules. However, for the most part, the NEMSIS TAC does not correct identified errors. The NEMSIS TAC does not have the resources to require states or agencies to correct errors retrospectively, but errors are reported to states, with hopes of future data refinement. Thus, the information contained in this dataset are provided as reported by states.
