Healthcare Cost & Utilization Project (HCUP)


The Healthcare Cost and Utilization Project (HCUP) is a family of health care databases and related software tools and products developed through a Federal-State-industry partnership. The HCUP databases, which are available for purchase, bring together the data collection efforts of State data organizations, hospital associations, private data organizations, and the Federal government to create a national information resource of patient-level health care data. HCUP databases contain a core set of clinical and nonclinical information found in a typical discharge abstract including all-listed diagnoses and procedures, discharge status, patient demographics, and charges for all patients, regardless of payer (e.g., persons covered by Medicare, Medicaid, private insurance, and the uninsured). In April of 2007, numerous State databases not previously released became available for purchase through the HCUP Central Distributor. These databases increase the volume of inpatient, emergency department, and ambulatory surgery data available to those interested in conducting health care research.

HCUP databases include:

  • State inpatient databases
  • State ambulatory surgery databases 
  • State emergency department databases
  • Nationwide inpatient sample
  • Kids' inpatient database

HCUPnet is a free interactive tool for online analysis of HCUP data.
