This historic 1977 image depicted two Centers for Disease Control (CDC) public health adviser working on a pilot study known as the Study on the Efficacy of Nosocomial Infection Control (SENIC) Project, which measured the accuracy of a system, designed by Robert W. Haley, MD, that detected hospital acquired infections through the analysis of medical records. SENIC was ultimately used to measure the change of infection rates in a random sample of U.S. hospitals. In this picture, the two men appeared to be doing an in-line quality control analysis, by comparing the agreement of duplicate reviews of the same medical records. To this day, the SENIC Project is still is the largest national study ever done by CDC, and it established the scientific basis for the infection control programs that are in every hospital in the western world.
