Nationwide Emergency Department Sample (NEDS)
What is the NEDS?
The Nationwide Emergency Department Sample (NEDS) is part of the family of databases and software tools developed for the Healthcare Cost and Utilization Project (HCUP). The NEDS produces national estimates about emergency department visits across the country. The NEDS describes emergency department visits, regardless of whether they result in admission. One of the most distinctive features of the NEDS is its large sample size, which allows for analysis across hospital types and the study of relatively uncommon disorders and procedures.

The Healthcare Cost and Utilization Project (HCUP, pronounced "H-Cup") is a family of powerful health care databases, software tools, and products for advancing research. Sponsored by the Agency for Healthcare Research and Quality (AHRQ), HCUP includes the largest all-payer, encounter-level collection of longitudinal health care data (inpatient, ambulatory surgery, and emergency department) in the United States, beginning in 1988.
HCUP is a Federal-State-Industry Partnership that brings together the data collection efforts of many organizations — such as State data organizations, hospital associations, private data organizations, and the Federal Government — to create a national information resource. HCUP would not be possible without the contributions of data collection Partners from across the nation.
