A graduate of the University of Illinois College of Medicine, Sheldon Cohen has practiced internal medicine and served as the medical director of three organizations: Alexian Brother's Medical Center of Northwest Suburban Chicago, Cigna Health plan of Illinois, and Humanacare Plus of Illinois. The author taught internal medicine and physical diagnosis to medical students from Loyola University Stritch School of Medicine and the Chicago Medical School. Recognizing the fact that busy physicians are pressed for time and thus often fail to capture a thorough medical history, the author developed one of the first computerized medical history systems for private practice and wrote a paper on his experience with 1500 patients who utilized the system. This was one of the early efforts in promoting electronic health records, a work in progress to this day. Serving as a consultant for Joint Commission Resources of the Joint Commission on Accreditation of Healthcare Organizations, the author did quality consultations at hospitals in the United States, Rio de Janeiro, Brazil, Copenhagen, Denmark, and served as a consultant to the Ministry of Health in Ukraine, assisting them in the development of a hospital accrediting body. Dr. Cohen is the author of 36 books.
