KID File Specifications
The Kids' Inpatient Database (KID) is a set of pediatric hospital inpatient databases included in the HCUP family. These databases are created by AHRQ through a Federal-State-Industry partnership.
 
KID File Specifications

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. Each year of the KID is comprised of the core data file and one or more additional files, in ASCII text format. A Hospital Weights File is always included. Files for Severity Measures and for Diagnosis and Procedure Groups are also included, depending on the year. The following links provide file specifications for the KID including the data set name, number of records, total record length, number of bytes, and record layout.
