Automated Multiphasic Health Testing Research Articles

History of Medical Informatics: Fifty Years in Medical Informatics

SummaryAn overview of personal experiences in medical informatics based on Dr. Morris Collen’s 50 years of research in the field.A personal reminiscence and historical overview, focusing on the first two decades of medical informatics, when Dr. Collen began working with Dr. Sidney Garfield, the founder of Kaiser Permanente, leading to his involvement in computer-based medical care, through the development of the pioneering Automated Multiphasic Health Testing (AMHT) system, which they introduced into Kaiser clinics in Oakland and San Francisco.Statistical models for medical decision-making based on consultations with Jerzy Neyman and George Dantzig were incorporated into the AMHT, and tested on a large database of cases. Meetings with other pioneers in medical informatics at the Karolinska Institute led to the formation of the early society Salutas Unitas, and the many national and international collaborations which followed during the first two decades helped coalesce the field as clinicians and researchers investigated problems of medical data, decision support, and laboratory, hospital, and library information systems.Dr. Collen’s research and his many medical informatics activities significantly contributed to the growth of the field. The U.S. contributions are covered extensively in his book, A History of Medical Informatics in the United States, 1950-1990. Washington, DC: Am Med Informatics Association 1995.

Periodically repeated multi-phasic health tests—a unique data source for detecting subject-specific normal ranges

When a comprehensive health check-up is repeated for the purpose of health control, the individual clinical data should be evaluated carefully by a proper normal range, which must be specific to each subject, if early detection of disease is a goal. The Perfect Liberty Health Control System, a health plan run on a membership basis, has been giving its periodic multi-phasic health tests to all of the 24 000 + members biannually since 1970. Studies concerning health parameter dynamics have been made on the data obtained and these are important to the new challenging field of clinical laboratory examinations. Other helpful aspects of this punctually repeated AMHTS (Automated Multi-phasic Health Testing) on a lifetime membership basis are also presented, such as cancer detection accuracy, protection from unnecessary X-ray exposure during examinations and a new form of physician's examination supported by current laboratory-data preview.

EVALUATION OF AUTOMATED MULTIPHASIC HEALTH TESTING IN THE SURVEY OF THE NORTH‐WEST REGION OF MELBOURNE

The results of automated multiphasic health testing (AMHT) in a randomly selected population of 664 subjects are reported. AMHT revealed a number of conditions that had not been diagnosed previously. A total of 535 newly diagnosed conditions in 301 patients could be attributed to the survey. The yield of new diagnoses by AMHT was not affected by previous surgery attendance or by attendance intervals. Follow-up over one year revealed that treatment was recommended for 342 of the 535 newly diagnosed conditions and that the response was satisfactory in 189 (55%), but the "uncertain" response of 124 (36%) should be investigated by more thorough follow-up in future projects. It is concluded that AMHT is beneficial because of the amount of information that is revealed, because of the financial value and because of the benefit to patients.

Automated multiphasic health testing, a diagnosis in three parts: Parts II and III.

Automated Multiphasic Health Testing (AMHT) is a sophisticated, computer-based technique for patient data gathering, analysis, storage, and print-out. The technique has been erroneously associated in the minds of physicians with the single application of population health "screening" while it is, in fact, broadly applicable to the entire health-care delivery process. During the past several years, the technique of AHMT has been refined, and computer-based systems have been applied to medical functions such as hospital pre-admission testing, the performance of triage in the HMO environment, and the development of patient histories and physiological data in the outpatient clinic. Such applications have been shown to reduce cost and increase physician productivity. This paper traces the history of AMHT over the past decade as seen through the eyes of a participant, from within the medical industry. A case is presented in this three-part paper for the use of AMHT techniques as basic tools in containing health-care costs and in providing expanded medical care throughout the United States.

Health service utilization by smokers and nonsmokers.

Among members of a prepaid health plan, a sample of white men and women age 20 years or older was studied for differences in utilization of several types of health services by cigarette smokers, nonsmokers, and exsmokers. Health examinations, especially Automated Multiphasic Health Testing (AMHT), were used least by smokers. Smoking was associated with an augmented social class difference in use of health examinations. AMHT in particular was used most frequently by ex-smokers. Frequency of doctor office visits was highest for male smokers and female ex-smokers. Male smokers aged 60 years or older made far the highest demand of all age-sex groups for hospital services, the most expensive type of health service. Cigarette smoking habits ought to be taken into account in estimating medical care utilization and costs that will he experienced by a particular population.

Automated multiphasic health testing: the TVA experience.

The Tennessee Valley Authority (TVA) has found automated multiphasic health testing (AMHT) to be an excellent complementary medical tool for providing health care for urban and nonurban employees. Automated multiphasic health testing adapted to a mobile unit has been particularly valuable in keeping the health of remote-area employees under surveillance. As a regional resource development agency, TVA is also interested in finding ways to upgrade the health of the area’s people. In cooperative community projects, TVA has helped to demonstrate the potential value of AMHT for introducing nonurban populations into a health care system and for improving existing health care by providing previously unavailable diagnostic services. But AMHT must be used in conjunction with organized health care delivery systems. If it is not, confusion in health care delivery and physician rejection may result.

A program to measure the impact of multiphasic health testing on health differentials between poverty and nonpoverty groups.

Periodic automated multiphasic health testing (AMHT) for poverty and nonpoverty groups enrolled in HIP is being integrated with an action program that utilizes paramedical personnel and the medical care resources within the Plan. The primary question under investigation is whether through AMHT and the activities generated by it, the anticipated gaps in health status and health-related behavior and understanding between the two groups can be narrowed. Control groups have been established to provide the basis for judging whether observed changes are independent of the project's activities. Feasibility, cost, and manpower requirements are also to be determined for a system in which physician referrals are limited to patients who meet specified criteria. Major sources of information for the study groups include a battery of tests differing moderately from those included in other AMHT programs, and a health inventory that covers, in addition to questions usually found in a health history, a broad range of items concerned with patterns of health care, practices, attitudes, disability, and limitations of function. Outcome measures will be of two types— those that might be inferred from information about health behavior and those that reflect a change in health status.

Multiphasic Health Testing in Medicine

To the Editor.— Dr. Howe's Application of Automated Multiphasic Health Testing in Clinical Medicine ( 219 :885, 1972) fails to note that the Judicial Council in March 1971 and the Council on Medical Service in December 1971 issued guidelines for Automated Multiphasic Health Testing (AMHT) facilities. These two guidelines not only complement Dr. Howe's article but emphasize that the Association, itsJournal, and its committees and councils help the physician through MEDICINE IN METAMORPHOSIS.

Psychiatric screening through multiphasic health testing.

The author discusses automated multiphasic health testing (AMHT) and its potential value to psychiatry. He describes screening instruments and techniques being developed and tested at the University of Florida for specific use in AMHT centers. These include psychophysiological measures, blood chemical indicators of psychological state, and paper-and-pencil psychological instruments that measure psychosocial history, psychiatric symptoms, and critical social readjustments.

The Technology of Automated Multiphasic Health Testing

``The Technology of Automated Multiphasic Health Testing (AMHT)'' was examined in Davos, Switzerland, during September 14-18, 1970, at the first international conference supported by the Engineering Foundation. The 159 conference members from 14 different nations discussed AMHT on the basis of its involvement in the use of automated laboratory equipment and medical instruments in combination with computers to provide numerous accurate and reliable tests as well as other procedures to a large number of people with a minimum of highly trained personnel. Topics covered in the plenary sessions included ``AMHT in Perspective,'' ``Recent Progress in AMHT,'' ``Utilizing AMHT in Developing Countries,'' ``The Role of the Engineer in AMHT,'' ``AMHT in Patient Surveillance and Patient Management,'' ``How to Organize and Operate an AMHT Facility,'' and ``Device Safety.'' A special session was presented on ``Clinical Chemistry.'' Evening workshops were held on ``Quantitative Neurological Evaluation,'' ``The Role of the Engineer in AMHT,'' ``Trend Detection in Cardiology,'' ``Automatic Cytology,'' and ``Blood Chemistry Measurements?New Approaches to Automation.'' Conference proceedings will be published by the Engineering Foundation.
