HCUP Fact Book No. 6

To help fulfill its mission of providing information on the U.S. health care system, the Agency for Healthcare Research and Quality (AHRQ) develops and sponsors databases that include the Healthcare Cost and Utilization Project (HCUP). Through HCUP, AHRQ has taken a lead in developing databases, software tools, and statistical reports to inform policymakers, health system leaders, and researchers at the Federal, regional, and State levels.

Hospitalization in the United States, 2002, summarizes information from the Nationwide Inpatient Sample (NIS), an all-payer hospital database maintained by AHRQ. This report updates an earlier Fact Book that described hospital care in 1997. AHRQ has attempted to maintain the general content of the earlier document to allow for easy comparison between 1997 and 2002 hospital care information.
