Operational data from a multiphasic test center operated by a city health department was subjected to systems analysis to derive implications for improved sensor management. The actual data process used facilities in Richmond, Va., Portland, Ore., and Washington, D. C., and required several weeks to complete assembly. The process had 3808 subjects at an average flow rate of 1.49 subjects per minute. Of this group, 1530 subjects accepted an offer of a free electrocardiogram to be given a week later, but only 82.1 percent actually took the later test. The data analysis was confined to 361 males past the age of 40, but was further restricted to those 252 with complete records. A simulated data process with capability for on-line test modification to assemble partial records and to give retest if necessary was studied. In addition to control of patient apathy and early treatment of suspect individuals, additional benefits may be possible. All abnormal X-rays were found in subjects whose other data considered as an ensemble predicted suspected trouble. The complete system viewpoint implemented by suitable processors may permit more effective use of extremely scarce talent, such as that of radiologists.
