One of the major academic figures in American public health was Lester Breslow, MD, who passed away last year at the age of 97. Dr. Breslow was a former dean of the Fielding School of Public Health at UCLA and director of the California Department of Public Health from 1965-1968.
He was also president of the American Public Health Association from 1968 to 1969. Central to Dr. Breslow’s research was mathematical support for the premise that improving personal habits such as reducing smoking, eating better, and sleeping well could have a significant impact on life longevity and quality.
Dr. Breslow was also a pioneer in multiphasic screening and an advocate for the Automated Multiphasic Health Test developed by Kaiser Permanente’s Morris Collen, MD, an early medical informatics guru who turns 100 this November.
National Public Health Week, April 1-7, is a good time to revisit Kaiser Permanente’s role in the early recognition of preventive care as a way to address public health issues.
Breslow had developed the original multiphasic screening (the examination of large numbers of people with a series of tests for detecting diseases) during the 1940s, and Collen improved upon it with new technology. The first beneficiaries of Collen’s multiphasic process were members of the International Longshoremen’s and Warehousemen’s Union in 1951.
The AMHT was a battery of tests, administered in an efficient routine by medical professionals and supported by then-new mechanical and chemical analytic devices. The results were funneled into a powerful mainframe computer.
From a public health perspective, the ability to efficiently diagnose communicable and noncommunicable diseases not only benefitted the individual patient, it also helped to stem public health risks as well.
In Breslow’s 1973 Preventive Medicine article, “An Historical Review of Multiphasic Screening,” he noted: “Automated multiphasic screening opens the possibility of extending the health-maintenance type of health care to all groups of the population, particularly including those most likely to suffer from the conditions now responsible for the greatest amount of disability and death.”
Dr. Collen taught two semesters at UC Berkeley’s School of Public Health during the spring and fall of 1965; much of the curriculum explored the uses of multiphasic exams. Students included physicians engaged in their continuing medical education.
Final papers for the classes included such subjects as “Evaluation of Environmental Toxins Utilizing Automated Methods” by David R. Brown, “Obesity and its Measurements as it Relates to a Multiphasic Screening Program” by Clarence F. Watson, MD, and “Biological Effects of Magnetic Fields” by Earl F. White.
Although the multiphasic screening as it was developed in the 1960s has been replaced by other diagnostic methods, the efficient application of medical diagnostic tools – and the enormous Kaiser Permanente patient database that has accumulated over the years – continues to advance public health.
