Advances in multiphasic screening and testing.

The multiphasic testing center of the future will probably be used both for periodic screening tests and for referrals by practicing physicians. Recent widespread interest of several branches of the Federal Government in multiphasic screening stems from the possibility that, through its use, the enormous cost of chronic illness to the country may be reduced.Recent advances in automation and the storage, retrieval, and analysis of data by computers make it economically feasible to obtain much more information about the patient's health than ever before. New instrument developments include both screening and diagnostic analysis of electrocardiograms by computers, analysis of heart sounds by computer, and a wide variety of other physiological and biochemical instruments. To allow for the inclusion and evaluation of these new procedures, a number of multiphasic testing centers will be needed which can do both research and routine testing. Close cooperation between the medical profession, the public health services and industry will be needed to best serve both the public and the medical profession.
