In December 2016, a retrospective study from the Mayo Clinic indicated that a surgeon can safely be responsible for two overlapping procedures when critical parts of the procedures are not coincident. The study of overlapping operations showed no difference in patient outcomes, but increased effectiveness and time management.
Paul Kurlansky, MD, Associate Director of Columbia’s Center for Innovation and Outcomes Research at NYP/Columbia, stresses that there is a big difference between overlapping and concurrent operations. With overlapping procedures, "surgeons cannot be booked to perform critical parts of two operations at the same time," he said.
Craig Smith, MD, surgeon-in-chief, NYP/Columbia told Medscape Medical News has been performing overlapping operations routinely for more than 30 years, and he believes his judgment should be trusted with regard to when and how to do them.
