Announcing a New, Enhanced HCUPnet

If you are a policymaker who needs access to hospital statistics, point your Web browser to the new and expanded HCUPnet (, a free, interactive online service for identifying, tracking, analyzing, and comparing statistics on hospital care collected by the Healthcare Cost and Utilization Project. National and regional data in HCUPnet are derived from the 1997 HCUP Nationwide Inpatient Sample, the largest all-payer inpatient database in the United States.

Who should investigate HCUPnet:

  • Federal and State policymakers.
  • Health policy analysts.
  • Health program administrators.
  • Hospital and health plan analysts.
  • Health services researchers.

Key features of HCUPnet include:

  • Choice of data from a National sample or participating State database (as of February 2000, participating States are Arizona, California, Colorado, Florida, Iowa, Massachusetts, New Jersey, Oregon, South Carolina, and Washington).
  • Searching on user-defined subset of inpatient stays (all stays, principal diagnoses, or principal procedures).
  • Selection of desired outcomes and measures.
  • Selection of one or a comparison of two or more patient groups by age, sex, insurance status, or median income of patient's ZIP code.
  • Analysis of one or comparison of two or more hospital types by ownership, teaching status, location bedsize, and geographic region.

Possible uses of HCUPnet include:

  • Profile hospital utilization patterns of Medicaid clients.
  • Determine the percentage of births not covered by public or private insurance and whether outcomes are different for uninsured and insured births.
  • Track the frequency of hospitalizations for certain rare conditions, such as sickle cell anemia, or uncommon procedures, such as organ transplants.
  • Compare the diffusion of new hospital technologies across teaching versus nonteaching hospitals or across States.
