A common way of scheduling surgeries to expand patient access to care and improve hospital efficiency, known as "overlapping surgeries," is as safe and provides the same outcomes for patients as non-overlapping surgeries, a Mayo Clinic study has found. Spacing operations so a surgeon has two patients in operating rooms at the same time is a common practice in surgery at Mayo and other leading medical institutions. It gives patients greater access to qualified surgeons, allows more efficient use of operating rooms, and avoids unnecessary downtime for surgeons. A Mayo Clinic study compared the outcomes of thousands of such overlapping surgeries with non-overlapping operations at its Rochester campus and found no difference in the rates of postoperative complications or deaths within a month after surgery between the two groups. The findings are published in the Annals of Surgery.
