Summary: The Kids' Inpatient Database is one database in the ARHQ's Healthcare Cost and Utilization Project (HCUP) family of databases. The KID contains hospital stay information for children 20 years of age and younger (18 and younger for 1997). Data are taken from a sample of pediatric discharges from 3,500+ hospitals in selected states. The 2006 KID includes data from Arizona, Arkansas, California, Colorado, Connecticut, Florida, Georgia, Hawaii, Iowa, Illinois, Indiana, Kansas, Kentucky, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Nebraska, Nevada, New Jersey, New Hampshire, New York, North Carolina, Ohio, Oklahoma, Oregon, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Utah, Vermont, Virginia, Washington, West Virginia, and Wisconsin. Data items in the KID include demographics, diagnoses, procedures, admission and discharge status, and payer information. For some states, the KID can be linked to hospital-level data from the American Hospital Association's Annual Survey of Hospitals.
