The Kids' Inpatient Database
The Kids' Inpatient Database (KID) is one in a family of databases and software tools developed as part of the Healthcare Cost and Utilization Project (HCUP). 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 Introduction to the KID, 2009 (PDF file, 795 KB; HTML).

The Kids' Inpatient Database (KID) is a unique and powerful database of hospital inpatient stays for children. The KID was specifically designed to permit researchers to study a broad range of conditions and procedures related to child health issues. Researchers and policymakers can use the KID to identify, track, and analyze national trends in health care utilization, access, charges, quality, and outcomes.
The KID excludes data elements that could directly or indirectly identify individuals. Purchase of the files is open to all users who sign a Data Use Agreement (PDF, 42 KB; HTML). Users must agree to use the database for research and statistical purposes only and to make no attempts to identify individuals. Identities of institutions are available only in States where data sources already make that information public or agree to its release. For these institutions and for research purposes only, linkage is possible to data to the American Hospital Association (AHA) Annual Survey Database (Health Forum, LLC © 2010).

The KID is the only hospital administrative dataset designed specifically to assess use of hospital services by newborns, children, and adolescents. The KID enables studies of specific conditions, procedures, and subpopulations that often cannot be assessed with other databases because children account for a relatively small proportion of hospital stays. Using the KID, it is possible to study varied topics including the incidence of uncommon conditions such as congenital anomalies, the economic burden associated with specific procedures or conditions such as adolescent pregnancy, and the pediatric conditions most often associated with particular outcomes such as death in the hospital. By integrating data from statewide health data organizations, the KID is a uniform, multi-State database that supports health care policy research on a variety of topics including:
