Overview of the Kids' Inpatient Database (KID)
The Kids' Inpatient Database (KID) is part of a family of databases and software tools developed for the Healthcare Cost and Utilization Project (HCUP). HCUP inpatient data are based on administrative data—discharge abstracts created by hospitals for billing. The KID is the largest publicly-available all-payer pediatric inpatient care database in the United States. Unweighted, it contains data from approximately 3 million pediatric discharges each year. Weighted, it estimates roughly 7 million hospitalizations. The KID has been produced every three years (1997, 2000, 2003, 2006, 2009, 2012). Hospital discharge data for 2015 contains a mix of ICD-9 and ICD-10 data (the first three quarters of 2015 contain ICD-9 data and the last quarter contains ICD-10). Because of the complexities of analyzing a mixed data year, the next KID will be available for 2016 and will be comprised of ICD-10 data only.
Developed through a Federal-State-Industry partnership sponsored by the Agency for Healthcare Research and Quality, HCUP data inform decisionmaking at the national, State, and community levels. This page provides an overview of the KID. For more details, see KID Database Documentation and the Introduction to the KID, 2012 (PDF file, 424 KB; HTML). Contents:

The KID yields national estimates of hospital inpatient stays for patients younger than 21 years of age. The unique design of the KID enables national and regional studies of common and rare pediatric conditions. The KID can be used to identify, track, and analyze national trends in health care utilization, access, charges, quality, and outcomes. KID data are available every three years from 1997 through 2012, which allows researchers to analyze trends over time. The number of States in the KID has grown from 22 in the first year (1997) to 44 in 2012. Key features of the most recent KID database year (2012) include:

The KID contains clinical and resource-use information that is included in a typical discharge abstract, with safeguards to protect the privacy of individual patients, physicians, and hospitals (as required by data sources). It contains more than 100 clinical and nonclinical data elements for each hospital stay, including:

As a uniform, multi-State database, the KID promotes comparative studies of health care services and supports health care policy research on a variety of topics, including:

Spanning 15 years of data, the KID can be used for longitudinal analyses; however the database underwent changes in 2000. In order to facilitate analysis of trends including the 1997 KID, an alternate set of KID discharge weights for the 1997 HCUP KID were developed. These trend weights were calculated in the same way as the weights for the 2000 and later years of the KID. (Trend analyses for 2000 and later data do not need the KID trends weights.) The report, Using the Kids' Inpatient Database (KID) to Estimate Trends, includes details regarding the KID trends weights and other recommendations for trends analysis. The KID trends report is available on the HCUP-US Web site at http://www.hcup-us.ahrg.gov/reports/methods/2007_02.pdf, and the KID trends weights are available on the HCUP-US Web site at https://www.hcup-us.ahrq.gov/db/nation/kid/kidtrends.jsp |
