Information system linking a medical school with practitioners and hospitals.

A recently established medical information network uses computers and telephone lines to link rural Georgia medical practitioners, Georgia hospitals, and the Mercer University School of Medicine (MUSM) in Macon, Georgia. This network, the Georgia Interactive Network for Medical Information (GaIN), provides a service and educational support system for its members. The GaIN model embodies many of the educational and information management principles endorsed by two reports by the Association of American Medical Colleges: the 1984 report of the Project Panel on the General Professional Education of the Physician and a 1982 project report called "Academic Information in the Academic Health Sciences Center.

Artificial intelligence in medicine: the commercial realities.

Psychological, technical, and financial elements all contribute to the hurdles that must be surmounted before AI technology will achieve commercial success.

Respiratory therapy as a component of an integrated hospital information system: the Parkland On-Line Information System (POIS).

Information handling is an important part of the activities of health care professionals, and the Parkland On-line Information System (POIS)--a computerized hospital information system--was established to more efficiently handle the processing and storage of information in our institution. Computerization of a respiratory therapy department is more effective if done in the context of a comprehensive, integrated hospital information system. Information and requests for services flow into the respiratory therapy departmental computer from other hospital terminals, and information, such as patient charges and statistical data, flow out of the departmental computer to those requesting such information.

A computer-based scintigraphic method for sizing acute inferior myocardial infarcts.

A modeling procedure, employing multiple 99mTc-PYP myocardial scintigrams, was applied to acute inferoposterior myocardial infarcts in 12 dogs. Four modeling schemes were developed, and the model volume predictions were correlated with morphometrically determined infarct masses. Correlation values ranged from r = 0.

Government regulations and other influences on the medical use of computers.

This paper presents points brought out in a panel discussion held at the 12th Hawaiian International Conference on System Sciences, January 1979. The session was attended by approximately two dozen interested parties from various segments of the academic, government, and health care communities. The broad categories covered include the specific problems of government regulations and their impact on specific clinical information systems installed at The University of Texas Health Science Center at Dallas, opportunities in a regulated environment, problems in a regulated environment, vendor-related issues in the marketing and manufacture of computer-based information systems, rational approaches to government control, and specific issues related to medical computer science.

Impact of government regulations on two management and clinical information systems in a medical school environment.

Administrative and legal requirements and, in particular, federal and state government health care assistance and social services program regulations all combine to add complexity to the management and operation of ambulatory and inpatient health programs. This paper describes how constantly changing government regulations and differences in interpretations and definitiions have been expensive, time-consuming and sometimes detrimental to health care delivery for two large management and clinical computer-based information systems.

Medical applications in the TANDEM-16 multiple computer system environment.

This paper addresses the question of reliability and the TANDEM-16 approach to facilitate reliable computers. Specifically, the use of the TANDEM-16 within the medical environment is described. Three current applications within the Medical Computing Resources Center at The University of Texas Health Science Center at Dallas are developed, each characterized by different reliability considerations.

Comparative study between the SFS and LFS rotation as a possible morphogenic mechanism.

Cephalometric tracings of twenty-seven untreated adult Caucasians, selected on a clinical impression of reduced lower facial height were studied and compared with tracings of nine untreated adult Caucasians with increased lower facial height. Various linear and angular measurements for both groups were analyzed and compared. As has been previously described for the SFS, the LFS group can be subdivided into at least two subtypes.

An automated clinic management system for a family planning network.

The medical information, financial, and logistic aspects of a comprehensive computer-based Appointment, Registration, Information System, and Evaluation (ARISE) are analyzed for the management of a family planning program serving 30,000 patients annually. An overview of the existing computer system network is presented with descriptions of the interactive master patient index, the batch appointment process, the management statistics package, and Department of Health, Education, and Welfare (HEW) reporting. Emphasis is placed on the financial management control system which includes 1) procedures for third-party submission of claims for payment, in particular Titles IVA, XX, and XIX (Social Security Act), together with discussion of related administrative requirements; 2) technics of auditing data integrity including systematic sampling of collected data; and 3) the process of billing and receipts collection.

Experimental infarct sizing using computer processing and a three-dimensional model.

A method for noninvasive sizing of myocardial infarction, in which data from technetium-99m stannous pyrophosphate scintigrams and a three-dimensional model were used, was tested on experimental, acute anterior infarcts in dogs. The results indicate that the method does size experimental anterior infarcts accurately, but further testing will be necessary to assess the capabilities of the technique for sizing other types of infarcts.

The long face syndrome: vertical maxillary excess.

There is a clinically recognizable facial morphology, the long face syndrome, which has been incompletely described in the literature. On the basis of the clinical summary in thirty-one adults with this syndrome, an analysis of esthetics, skeletal morphology, and occlusion was undertaken. Herein we report on these findings, which confirm that this basic dentofacial deformity is associated with excessive vertical growth of the maxilla.

Rentran. An on-line computer-based regional kidney transplant matching system.

An interactive on-line computerized renal transplant matching system called RENTRAN which serves the Southwest Kidney Transplant Region is described. The region consists of one transplant center in Arkansas, two in Oklahoma, and six in Texas. The computer used is the DECsystem-10 located in the Medical Computing Resources Center at Dallas.

Simple method for computer-aided analysis of echocardiograms.

The use of echocardiography in the diagnosis and assessment of heart disease is increasing as greater familiarity is obtained with this noninvasive procedure. Quantitative evaluation of echocardiographic studies has heretofore required time-consuming manipulation of mathematical formulas. A simple method utilizing a sonic digitizing tablet has been developed for computer-aided analysis of M-mode echocardiograms.

Soft-hard tissue correlations and computer drawings for the frontal view.

Hard and soft tissue measurements were obtained for nine Caucasian women. Based on these measurements, regression formulas were derived to approximate the soft tissue covering based on hard tissue data. The results are presented iconically by computer drawings.
