Methods of EMNet findERnow
Since 2001, the Emergency Medicine Network has created and maintained the National Emergency Department Inventory (NEDI) - USA, a database of all US emergency departments (EDs). This research has led to numerous scientific publications. In late 2009, we mapped the approximately 5,000 EDs with a primary motivation of providing a community service. Our publicly available smartphone app, EMNet findERnow was launched in 2010 and depends on the accuracy of the geographic coordinates assigned to each ED in the NEDI-USA database.

In addition to tracking the location of all US EDs, EMNet has surveyed all >5,000 US EDs annually since 2016 to ask about additional – but still basic – ED characteristics. The results from this survey are used to perform health policy research on U.S. emergency care and to upgrade the EMNet findERnow app.
To learn more about the data from the national survey that have been incorporated into the app (annual number of ED visits, % of annual visits by children, separate pediatric area, and pediatric emergency care coordinator [PECC]) click here.
EMNet also compiles national data on trauma centers and burn centers. To learn more about these data, click here.
The information in EMNet findERnow is updated continuously as EDs open, close, and move. If you have any questions about the data in findERnow, or if you would like to report a possible change, please contact us at firstname.lastname@example.org.
