Yielding national estimates of emergency department (ED) visits, the NEDS is the largest all-payer ED database in the United States and contains information about geographic, hospital, patient, and visit characteristics. The NEDS is one of the databases in the family of products generated by the Healthcare Cost and Utilization Project (HCUP) of the Agency for Healthcare Research and Quality (AHRQ).
