HCUP 2010 Nationwide Inpatient Sample (NIS) Database released
The Healthcare Cost and Utilization Project (HCUP) Nationwide Inpatient Sample (NIS) featuring 2010 data is now available. The NIS (http://hcup-us.ahrq.gov/nisoverview.jsp) is the largest all-payer inpatient care database in the United States.
The NIS is nationally representative of all short-term, non-Federal hospitals in the U.S. It is drawn from the HCUP State Inpatient Databases (http://hcup-us.ahrq.gov/sidoverview.jsp) and includes more than 8 million hospital stays. The NIS includes all patients from each sampled hospital, regardless of payer—including persons covered by Medicare, Medicaid, private insurance, and the uninsured.
The NIS contains data from 45 States and can be weighted to produce nationwide estimates, allowing researchers and policymakers to use the NIS to identify, track, and analyze national trends in health care utilization, access, charges, quality, and outcomes. The vast size of the NIS enables analyses of infrequent conditions, uncommon treatments, and special patient populations.
As part of the HCUP database family, the NIS is considered by health services researchers to be one of the most reliable and affordable databases for studying important health care topics.
The 2010 NIS can be purchased through the HCUP Central Distributor (http://hcup-us.ahrq.gov/tech_assist/centdist.jsp) and data can be accessed via HCUPnet (http://hcupnet.ahrq.gov), a free online query system. Additional information about the NIS and other products is located on the HCUP-US Web site at http://hcup-us.ahrq.gov.
