Frederick C. Ryckman, MD

graduated from Michigan State University in Biology/Zoology and from the University of Michigan Medical School with high honors in 1973. He completed his General Surgery Residency at the University of Florida in1982 and thereafter a fellowship in Pediatric Surgery at Cincinnati Children’s Hospital. He has remained a practicing surgeon at the University of Cincinnati / Cincinnati Children’s Hospital since 1984, where he is presently a Professor of Surgery. He has been the Surgical Director of solid organ transplantation leading the liver, small intestine, and multi-visceral transplant services since 1985. His other practice interests include long-term heart/lung bypass (ECMO) and hepatobiliary surgery in infants and children. He is the Clinical Director of the Pediatric Surgery Department and Director of the Pediatric Surgical Fellowship program.

Dr. Ryckman’s interest in OR management led to a collaboration with the Program for the Management of Variability in Health Care Delivery (now the Institute for Healthcare Optimization) to re-engineer flow management in the Operating Room at Cincinnati Children’s Hospital. Application of this methodology led to substantial improvements in access, utilization and safety. Ongoing efforts include use of the principals of decreasing variability and matching demand and capacity to better manage and enhance hospital wide flow. These initiatives use many of the management techniques emphasized by Dr. Eugene Litvak’s work. Dr. Ryckman's role as the Vice President of System Capacity and Perioperative Operations places him at the crossroads of patient safety, hospital wide patient flow, and daily operations management in the complex operating room environment of Cincinnati Children's Hospital.
