IHCIS, 2005-2007. The Impact National Managed Care Benchmark Database™ (formally known as Integrated Healthcare Information Services - IHCIS - prior to its purchase by Ingenix, Inc and referred to as IHCIS within GSK) is a comprehensive, de-identified U.S. healthcare claims database that is representative of the non-elderly, insurance-carrying population in the U.S. The database contains inpatient/outpatient and pharmacy claims, lab results and enrollment information on over 82 million lives from 1997 to 2007. Over 75 percent of all patients in the database have both medical and pharmacy benefits and, on average, 23.4 months of enrollment/claims information; the annual attrition rate is roughly 15-25 percent. The data are collected from over 45 different healthcare plans serving members across nine census regions. The database is HIPAA compliant and features encrypted member and provider IDs.
