2022 National Emergency Department Inventory – USA

EMNet performed its eighth annual national survey to better understand the nature of U.S. emergency departments (EDs). Briefly, we are contacting hospitals to obtain basic information about their EDs.

The results from this national survey will be used to perform health services research on U.S. emergency care and to enhance our existing app, findERnow (available for free on both iPhone and Android smartphones). If you have questions or would like more information, please contact us at emnet@partners.org.
