The 2015 NEMSIS Public-Release Research Dataset is now available! This dataset includes 30,206,450 EMS activations submitted by 10,137 EMS agencies serving 49 states and territories during the 2015 calendar year. Events submitted by states 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. To evaluate variation in inclusion criteria and the proportion of EMS events submitted by each state, visit http://www.nemsis.org/support/stateProgressReports/index.html and click on each state of interest.
To determine which states contributed to the 2015 dataset, click on this link. A User Manual associated with the NEMSIS Public-Release Research Dataset is available at this link. Initial SAS code is available to import an ASCII file to SAS, translate M:M tables to a flat file, generate a data specification file and, transform age and date/time values.
The 2015 NEMSIS Public-Release Research Dataset does not contain information that identifies patients, EMS agencies, receiving hospitals, or reporting states. To access the list of NEMSIS Version 2.2.1 National Elements and those shared at the public level please click here. Limited identifying information is available in the complete NEMSIS dataset, but may only be accessed with formal institutional review and approval by the NEMSIS TAC Advisory Board. In essence, identifying information may only be released in compliance with HIPAA requirements. To make a request for data including additional NEMSIS variables, contact N. Clay Mann (email@example.com).
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.
