Since 2001, the Emergency Medicine Network (EMNet) has created and maintained the National Emergency Department Inventory (NEDI)-USA, a database of all U.S. emergency departments or emergency rooms (ERs) open 24/7/365. This research has led to numerous scientific publications. In late 2009, EMNet mapped the approximately 5,000 total ERs in the U.S. with a primary motivation of providing a community service. In 2010, EMNet first launched the findERnow smartphone app to the public. Data in findERnow is based on the accuracy of the geographic coordinates assigned to each ER in the NEDI-USA database.

In addition to tracking the location of all U.S. ERs, EMNet has also been actively surveying all 5,000+ U.S. ERs annually since 2016 to confirm additional–but still basic–ER characteristics. The results from this survey have been used to perform health policy research on U.S. emergency care and to ensure the findERnow app remains up-to-date.
To learn more about the data from the national survey that have been incorporated into the app (including annual number of ER visits, % of annual visits by children, separate pediatric area, and pediatric emergency care coordinator [PECC]) click here.
The information in findERnow is updated continuously as ERs 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 email@example.com.
