Kids' Inpatient Database (KID)
The Kids' Inpatient Database (KID) is composed of data on hospital inpatient stays for children and is specifically designed to allow researchers to study a broad range of conditions and procedures related to children's health. Researchers and policymakers can use KID data to identify, track, and analyze health care utilization, access, charges, quality, and outcomes.
The KID is one in a family of databases that make up the Healthcare Cost and Utilization Project (HCUP). The HCUP databases, related software tools, and other products were developed through a Federal-State-Industry partnership and sponsored by AHRQ. HCUP databases are derived from administrative data and contain encounter-level, clinical, and nonclinical information, including all-listed diagnoses and procedures, discharge status, patient demographics, and charges for all patients, regardless of payer (e.g., Medicare, Medicaid, private insurance, uninsured), beginning in 1988. KID data first became available in 1997 and is produced every 3 years.
