- catalog description "In 1988 the NHDS was redesigned to provide geographic sampling comparability with other surveys conducted by the National Center for Health Statistics (NCHS), to update the sample of hospitals selected into the survey, and to maximize the use of data collected through automated systems. The sample included with certainty all hospitals with 1,000 or more beds or 40,000 or more discharges annually. The remaining sample of hospitals is based on a stratified three-stage design. The first stage consists of a selection of 112 primary sampling units (PSU's) that comprise a selection of 112 probability subsample of PSU's used in the 1985-1994 National Health Interview Surveys. The second stage consists of a selection of non-certainty hospitals from the sample PSU's. At the third stage a sample of discharges was selected by a systematic random sampling technique. For 1989, the NHDS sampling frame consists of eligible hospitals which began accepting inpatients before Sept. 1, 1987, and were listed in the April 1987 SMG Hospital Market Data Tape (SMG Marketing Group, Inc. 1989).".
