Dr. Thomas Sitzman is a cleft surgeon and health services researcher at Phoenix Children’s Hospital in Phoenix, Arizona. He completed his plastic surgery training at the University of Wisconsin in Madison, Wisconsin, and his fellowship in pediatric plastic surgery at the Hospital for Sick Children in Toronto, Ontario. Dr. Sitzman’s research includes comparing the effectiveness of existing surgical interventions in cleft care, studying provider-based variation in cleft care delivery, and developing outcomes measures that support quality improvement and quality assurance activities in cleft care. He has been heavily involved in the Americleft Project and helped establish the Americleft Surgeon Subgroup. His recent work has explored the variation in secondary palate surgery across surgeons and hospitals, the feasibility of surgeon-delivered audit and feedback among cleft surgeons, and the role of structured care delivery processes in reducing use of secondary surgery.
