It is a continuous survey based on a sample of medical records of patients discharged from a national sample of these hospitals. The survey contains information on the patients' demographic characteristics (sex, date of birth, age, race, and marital status), dates of admission and discharge, discharge status, diagnoses, and surgery performed.

Sampling is done in two stages. Sample hospitals are drawn with probabilities ranging from certainty for large hospitals to 1 in 40 for the smallest hospitals. Sample discharges are then selected by a random technique based on the patient's medical record number. The sampling ratio for selecting sample discharges within each hospital varies inversely with the probability of selection of the hospital. This is to assure that the overall probability of selecting a discharge is the same in each size class.

Universe: Discharges from short-stay hospitals listed in The National Master Facility Inventory of Hospitals and Institutions excluding military and VA hospitals as recorded on each hospital's daily discharge listing. Short-stay hospitals are defined as those facilities whose average inpatient stay is less than thirty days.
