December 27, 2017 - AHRQ Announces Release of a New HCUP Database - the 2015 Nationwide Emergency Department Sample (NEDS)

The Agency for Healthcare Research and Quality (AHRQ) just released a new Healthcare Cost and Utilization Project (HCUP) database the 2015 Nationwide Emergency Department Sample (NEDS). The MHDO is one of HCUP’s partners and it is the MHDO hospital data that is sent to HCUP that is then integrated into the national ED database. The NEDS was created to enable analyses of emergency department (ED) utilization patterns. Note as reported by AHRQ the ED serves a dual role in the U.S. healthcare system infrastructure, as a point of entry for approximately 50 percent of inpatient hospital admissions and as a setting for treat-and-release outpatient visits. The NEDS contains information about geographic, hospital, and patient characteristics as well as descriptions of the nature of the visits (i.e., common reasons for ED visits, including injuries). The NEDS is the largest all-payer ED database that is publicly available in the United States, containing information from 30.5 million ED visits at 953 hospitals that approximate a 20-percent stratified sample of U.S. hospital-owned EDs. Weights are provided to calculate national estimates representative of 143 million ED visits in the U.S. for calendar year 2015.

The 2015 NEDS is a publicly available database that can be purchased through the HCUP Central Distributor.
