Summary View help for Summary
This survey, which is part of a continuing sample of hospital discharge records, supplies medical and demographic information used to calculate statistics on hospital utilization. The data collection consists of data abstracted from the face sheets of the medical records for sampled inpatients discharged from a national sample of nonfederal short-stay hospitals. The variables include information on the patient's demographic characteristics (sex, age, date of birth, race, marital status), dates of admission and discharge, status at discharge, diagnoses, procedures performed, source of payment, and hospital characteristics, such as bedsize, ownership, and region of the country.

All hospitals with 1,000 beds or more in the original universe of short-stay hospitals were selected with certainty in the sample. All hospitals with fewer than 1,000 beds were stratified, the primary stratum depending on size and geographic region. Within each of these 24 primary strata, the allocation of the hospitals was made through a controlled selection technique so that hospitals in the sample would be properly distributed with regard to type of ownership and geographic division. Sample hospitals were drawn with probabilities ranging from certainty for the largest hospitals to 1 in 40 for the smallest hospitals. A total of 395 hospitals in the sample were in scope and agreed to participate. The within-hospital sampling ratio for selecting sample discharges varied inversely with the probability of selection of the hospital. The smallest sampling fraction of discharged patients was taken in the largest hospitals, and the largest fraction was taken in the smallest hospitals. In nearly all hospitals, the daily listing sheet of discharges was the frame from which the subsamples of discharges were selected within the sample hospitals. The sample discharges were selected by a random technique, usually on the basis of the terminal digit(s) of the patient's medical record number--a number assigned when the patient was admitted. The sample represents 0.7 percent of the estimated 29 million discharges in 1970.
