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Reader can be downloaded from the Adobe Systems Incorporated Website at: http://www.adobe.com. 7/08 This CD-Rom is superseded because this study is available from ICPSR Direct.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 Ambulatory Medical Care Survey (NHAMCS) was inaugurated in 1992 to fill a gap in data about ambulatory medical care in the United States. Although the National Ambulatory Medical Care Survey (NAMCS) collects annual data on patient visits to physician offices, it excludes the hospital emergency room and outpatient department visits that make up a large part of the total ambulatory care received each year. The 1993 NHAMCS provides data from samples of patient records selected from emergency departments (EDs) and outpatient departments (OPDs) of a national sample of hospitals. The resulting national estimates describe the use of hospital ambulatory medical care services in the United States. For the 1993 survey, data were collected from 228 OPDs and 395 EDs. Among the variables included are age, race, and sex of the patient, reason for the visit, physician's diagnoses, cause of injury (ED only), surgical procedures (OPD only), medication therapy, and expected source of payment.
