The findERnow app is based on data from the National Emergency Department Inventory (NEDI)-USA dataset, the most comprehensive database of all 24/7 emergency rooms (ERs) in the United States.
NEDI-USA and findERnow are maintained by staff at the Emergency Medicine Network (EMNet), based at Massachusetts General Hospital in Boston, Massachusetts. Each year, our team administers a national survey to all U.S. ERs to conduct health services research in emergency care and to keep findERnow up-to-date.
