Hallet J, Jerath A, Turgeon AF, et al. - This population-based cohort study was undertaken to assess if there is any link between anesthesiologist volume and short-term postoperative results for complex gastrointestinal (GI) cancer surgery. Eligibility criteria for inclusion was adult patients who had esophagectomy, pancreatectomy, or hepatectomy for GI malignancy from January 1, 2007 to December 31, 2018. A composite of 90-day major morbidity (with a Clavien-Dindo classification grade 3-5) and readmission was the primary outcome, which occurred in 36.3% and 45.7% of patients in the high-volume and those in the low-volume groups, respectively. Findings revealed a lower risk of adverse postoperative outcomes in patients who received care from high-volume anesthesiologists vs those who received care from low-volume anesthesiologists in this study population of adults who received complex gastrointestinal cancer surgery. In light of these data, organizing perioperative care to increase anesthesiologist volume to optimize patient results is supported.
