HOSPWT is the hospital-level weight on the HCUP nationwide databases - Nationwide Inpatient Sample (NIS) and Nationwide Emergency Department Sample (NEDS). To produce national estimates, use HOSPWT to weight sampled hospitals to all community hospitals located in the U.S. For detailed information about the development and use of discharge and hospital weights, see the year-specific Introduction report on the HCUP database of interest.
