Examination Components: Surveys, databases, discharges from acute care community hospitals from 47 states. Data are from billing data collected through a public or private data entity within each state. Databases include discharges from all hospitals in each of the states. HCUP standardizes the databases so that the data elements are standard across the various databases. Discharges from all acute care hospitals; data are collected yearly beginning in 1988. HCUP has the following components: HCUP NIS (National Inpatient Sample); HCUP KID (KID’s Inpatient Database); HCUP NEDS (Nationwide Emergency Department Sample); HCUP SID (State Inpatient Database); HCUP SASD (State Ambulatory Surgery Database), and HCUP SEDD (State Emergency Department Database).
