Healthcare Cost and Utilization Project (HCUP)
Overview
The Healthcare Cost and Utilization Project (HCUP) is a family of databases, software tools, and related products developed through a Federal-State-Industry partnership and sponsored by the Agency for Healthcare Research and Quality (AHRQ). HCUP databases are derived from administrative data and contain encounter-level, clinical, and nonclinical information including all-listed diagnoses and procedures, discharge status, patient demographics, and charges for all patients, regardless of payer, beginning in 1988. [1]
HCUP offers the following databases:
National (Nationwide) Inpatient Sample (NIS): largest publicly available all-payer hospital inpatient care database in the United States
Kids' Inpatient Database (KID): hospital inpatient stays for children and is specifically designed to allow researchers to study a broad range of conditions and procedures related to children's health
Nationwide Emergency Department Sample (NEDS): emergency department (ED) visits that do not result in an admission as well as ED visits that result in an admission to the same hospital
Nationwide Readmissions Database: designed to support various types of analyses of national readmission rates for all payers and uninsured individuals
State Inpatient Databases (SID): inpatient discharge abstracts from participating States, translated into a uniform format to facilitate multi-State comparisons and analyses
State Ambulatory Surgery and Services Databases (SASD): encounter-level data for ambulatory surgery and other outpatient services from hospital-owned facilities
State Emergency Department Databases (SEDD): discharge information on all emergency department visits that do not result in an admission
Please note: Access to HCUP databases is not free. Database releases must be purchased through the Online HCUP Central Distributor.
