Summary: |
The National Hospital Discharge Survey (NHDS) collects
medical and demographic information annually from a sample of hospital
discharge records. Variables include patients' demographic
characteristics (sex, age, race, marital status), dates of admission
and discharge, status at discharge, final diagnoses, surgical and
nonsurgical procedures, dates of surgeries, and sources of payment.
Information on hospital characteristics such as bedsize, ownership,
and region of the country is also included. The medical information is
coded using the INTERNATIONAL CLASSIFICATION OF DISEASES, 9TH
REVISION, CLINICAL MODIFICATION (ICD-9-CM).

Sample: |
The redesigned (as of 1988) NHDS sample includes 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 selection
of 112 primary sampling units (PSUs) that comprise a probability
subsample of PSUs used in the 1985-1994 National Health Interview
Surveys. The second stage consists of selection of noncertainty
hospitals from the sample PSUs. At the third stage, a sample of
discharges was selected by a systematic random sampling technique. For
1994, the sample consisted of 525 hospitals. Of these, 13 were found
to be ineligible. Of the 512 eligible hospitals, 478 hospitals
responded to the survey.

Restrictions: |
In preparing the data file(s) for this collection, the
National Center for Health Statistics (NCHS) has removed direct
identifiers and characteristics that might lead to identification of
data subjects. As an additional precaution NCHS requires, under
Section 308(d) of the Public Health Service Act (42 U.S.C. 242m), that
data collected by NCHS not be used for any purpose other than
statistical analysis and reporting. NCHS further requires that
analysts not use the data to learn the identity of any persons or
establishments and that the director of NCHS be notified if any
identities are inadvertently discovered. ICPSR member institutions and
other users ordering data from ICPSR are expected to adhere to these
restrictions.
