Heftier patients take a little longer in the operating room for lung cancer resection, although with an effect that appears limited to costs rather than outcomes, researchers found.
Duration of the procedure from room entry to exit rose by 7.2 minutes with every 10 kg/m2 higher body mass index (BMI, P<0.0001), Eric L. Grogan, MD, MPH, of Vanderbilt University Medical Center in Nashville, Tenn., and colleagues reported.
Obesity didn't appear to impact hospital stay or 30-day mortality in the registry study appearing in the December issue of the Annals of Thoracic Surgery.
While good news from the perspective of outcomes, Grogan's group pointed to economic consequences.
Each minute of OR time has been estimated to cost an average of $62, which would come to an extra $446 per 10 kg/m2 higher BMI.
