Outcomes of concurrent operations: results from the American College of Surgeons' National Surgical Quality Improvement Program.

Liu JB, Berian JR, Ban KA, et al. Ann Surg. 2017;266:411-420.

The practice of scheduling concurrent surgeries has raised concerns about inadequate supervision of trainees. This National Surgical Quality Improvement Program study used propensity score matching to compare outcomes of concurrent versus nonoverlapping surgeries and did not find any difference in risk of death or serious morbidity, reoperation, or readmission. The authors state that while these results are reassuring, there is a need for further study to determine the safety of concurrent surgery.
