National Hospital Discharge Survey, 1979-1992: Multi-Year Data (ICPSR 6983) RSS

Principal Investigator(s):

Summary:

The National Hospital Discharge Survey (NHDS) collects medical and demographic information annually from a sample of hospital discharge records. This data collection consists of data from the 1979-1992 NHDS files, split into non-newborn (Part 1) and newborn (Part 2) data. Variables include patients' demographic characteristics (sex, age, race, marital status), month of admission, 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).

Scope of Study

Subject Terms:   demographic characteristics, health care facilities, hospitalization, hospitals, illness, medical care, medical evaluation, medical procedures, medical records, patients, payment methods, treatment

Geographic Coverage:   United States

Time Period:  

  • 1979--1992

Date of Collection:  

  • 1979--1992

Universe:   Patient discharges from nonfederal short-stay hospitals located in the 50 states and the District of Columbia.

Data Types:   administrative records data

Data Collection Notes:

(1) Per agreement with NCHS, ICPSR distributes the data file(s) and text of the technical documentation for this collection as prepared by NCHS. (2) This multi-year dataset has several differences from the single-year files. First, for these multi-year files, records for newborns and non-newborns are separated into distinct files. Second, the multi-year files do not contain recodes for several basic variables. Finally, all blank fields from the single-year files have been removed in the multi-year files, which has resulted in a different data layout.

Methodology

Sample:   The sampling from 1965 to 1987 was a stratified, two-stage design. 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 1979-1992, the sample varies from 528 to 558 hospitals. The number found to be ineligible in this period varies from 7 to 66. Participating hospitals varied from 407 to 494.
