Effect of Surgical Day of Week on Postoperative Outcomes After Robotic-Assisted Pulmonary Lobectomy.

Abstract

Introduction Patients who have surgery late in the week could potentially receive different postoperative care due to a reduced weekend staff compared to patients who have surgery early in the week, who willbecared for by a full staff during the work week.Our aim was to determine if patients who underwent robotic-assisted video-thoracoscopic (RAVT) pulmonary lobectomy during the first half of the week had different outcomes than patients who also underwent RAVT pulmonary lobectomy during the second half of the week. Methods We analyzed 344 consecutive patients who underwent RAVT pulmonary lobectomy by one surgeon from 2010 to 2016.Depending on the day of the surgical procedure, these patients were either put into a Monday through Wednesday (M-W) group or a Thursday through Friday (Th-F) group.Patient demographics, tumor histopathology, intraoperative and postoperative complications, and perioperative outcomes were compared between groups using the Student's t-test, Kruskal-Wallis test, or chi-square (or Fisher's exact) test, with p≤0.05 as significant. Results There were more non-small cell lung cancers (NSCLCs) resected in the M-W group than in the Th-F group (p=0.005).Skin-to-skin and total operative times were greater for the Th-F group than for the M-W group (p=0.027 andp=0.017, respectively).There were no significant differences in any other variables assessed. Conclusions Our study showed that, despite reduced weekend staffing and potential differences in postoperative care, there were no significant differences seen in postoperative complications or perioperative outcomes based on surgical day of the week.
