NEDS: Database Documentation
The NEDS is a set of hospital-based emergency department databases included in the HCUP family. These databases are created by AHRQ through a Federal-State-Industry partnership.
 
 
The Nationwide Emergency Department Sample (NEDS)

The Nationwide Emergency Department Sample (NEDS) produces national estimates about emergency department (ED) visits across the country. The NEDS describes ED visits, regardless of whether they result in admission, and is an exceptional resource for conducting research on high-profile emergent health delivery issues. 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 links below provide detailed documentation for the NEDS.
