Comments: This study is on ICPSR Periodic Release 97003. The Periodic Release CD-ROM is a product designed for use on a Windows- or DOS-based personal computer and is intended for use as a means of data distribution. It may also be used within the Macintosh environment utilizing either system 7.0 and above or system 6.08 and the appropriate PC emulation software. The CD-ROM does not contain software for text or data searches, extraction or analyses. The files with the .EXE extension are self extracting files that were generated using Info-ZIP's ZIP compressor/archiver and PKWARE's ZIP2EXE utility for generating self-extracting files. Self-extracting files allow PC users to easily and quickly decompress and transfer the files to their equipment, usually a hard disk, without the need to install any extraction software locally. Files with .PDF extensions are provided as an electronic image file in Portable Document File (PDF) format. The PDF format was developed by Adobe Systems Incorporated and can be accessed using the Adobe Acrobat Reader. A copy of Acrobat Reader can be downloaded from the Adobe Systems Incorporated Website at: http://www.adobe.com. 7/08 This CD-Rom is superseded because this study is available from ICPSR Direct.

Abstract: 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).

In 1964, the National Center for Health Statistics initiated a continuous sample of hospital discharge records, collecting medical and demographic information for calculating statistics on hospital utilization, and on the nature and treatment of illness among the hospitalized population. In the surveys, which are made available in annual public use files, data are abstracted from medical records for a sample of patients discharged from a sample of nonfederal short-stay hospitals across the nation.
