The HCUP variable for hospital bedsize changed names and definitions across data years:
||Beginning in 1998
||Specific to region, location and teaching status
||Specific to location and teaching status
||Same as H_BEDSZ
For ST_BEDSZ, the hospital bedsize category is nested within location and teaching status (LOCTEACH).
|Location and Teaching Status
The hospital's location, teaching status, and bedsize were obtained from the AHA Annual Survey of Hospitals. Teaching hospitals have an AMA-approved residency program or have membership in the Council of Teaching Hospitals. Bedsize assesses the number of short-term acute beds in a hospital.
Hospital bedsize (ST_BEDSZ) is missing for some zero-weight hospitals for which the information was not available (see the File Composition for the Nationwide Inpatient Sample for a definition of zero-weight hospitals). Zero-weight hospitals are included in the 1988-1992 data for NIS, Release 1. Because relatively few hospitals were affected and the complexity of including these hospitals entailed considerable processing burden and costs, no zero-weight hospitals are included after 1992 in NIS Release 2 through Release 6.
