HCUP Releases 2013 Nationwide Emergency Department Sample (NEDS) Database

2013 Nationwide Emergency Department Sample (NEDS) Just Released!

The 2013 Nationwide Emergency Department Sample (NEDS) has been released and is available for purchase through the HCUP Central Distributor. Select statistics can be accessed via HCUPnet, the free online query system.



The NEDS is the largest all-payer emergency department (ED) database in the United States. It was created to enable analyses of ED utilization patterns and support understanding and decision-making regarding this critical source of health care. Constructed using records from both the HCUP State Emergency Department Databases (SEDD) and the State Inpatient Databases (SID), the 2013 NEDS contains data from nearly 30 million ED visits and encompasses all encounter data from 950 hospital-based EDs in 30 states – approximating a 20-percent stratified sample of EDs from community hospitals. Weights are provided to calculate national estimates pertaining to the almost 136 million ED visits that took place in 2013. The NEDS provides information on "treat-and-release" ED visits, as well as ED visits in which the patient was admitted to the same hospital for further care.



The HCUP family of health care databases and related software tools and products is made possible by a Federal-State-Industry partnership sponsored by the Agency for Healthcare Research and Quality (AHRQ)
