Abstract

Background Many authors have investigated the possible adverse effects among patients who underwent elective surgery on Friday when compared with patients operated earlier in the week. Nonetheless, the weekday effect is still a matter of debate. This study aimed at investigating the postoperative morbidity rates after lung cancer surgery and their relationship with the weekday the surgery took place.

Materials and Methods We retrospectively reviewed the clinical records of patients who underwent elective thoracotomic lobectomies for lung cancer. Categorical data were analyzed using the chi-square test or Fisher's exact test. Association between predictors and binary outcomes while considering the weekday stratification was determined with Cochran–Mantel–Haenszel statistics. To characterize the typical Friday patient, a multiple logistic regression analysis was performed.

Results A total of 817 patients (2015–2019) were identified. Complication rates divided by day of surgery were 164 (20.07%) for patients operated on Mondays, 182 (22.27%) on Tuesdays, 205 (25.09%) on Wednesdays, 172 (21.05%) on Thursdays, and 94 (11.51%) on Fridays. Crude morbidity rates by weekday were Monday 21.53%, Tuesday 20.51%, Wednesday 27.70%, Thursday 20.0%, and Friday 10.26%. No overall association between day of surgery and overall morbidity was found (ρ = 0.095). Median hospital length of stay was 5 days (range: 2–45 days), and there were no statistically significant differences between days. The Cochran–Mantel–Haenszel statistics showed no association between morbidity and the weekday.

Conclusion In patients undergoing elective lobectomies for lung cancer, the weekday of surgery was not statistically significantly associated with an increase in the risk of postoperative morbidity.
