Research has shown that patients admitted to the hospital on the weekend may experience worse outcomes compared to those admitted on weekdays (the ‘weekend effect’). This editorial highlights the challenges to empirically evaluate the underlying mechanisms contributing to the weekend effect. The authors propose viewing the weekend effect as a proxy for staffing levels and the influence of other factors influencing outcomes for patients admitted on weekends, such as patient acuity, clinician skill-mix and access to diagnostic tests or other ancillary services.

Scheduling overlapping surgeries has raised substantial patient safety concerns. However, research regarding the impact of concurrent surgery on patient outcomes has produced conflicting results. In this multicenter retrospective cohort study, researchers examined the relationship between overlapping surgery and mortality, postoperative complications, and surgery duration for 66,430 surgeries between January 2010 and May 2018. Although overlapping surgery was not significantly associated with an increase in mortality or complications overall, researchers did find a significant association between overlapping surgery and increased length of surgery. An accompanying editorial discusses the role of overlapping surgery in promoting the autonomy of those in surgical training and suggests that further research is needed to settle the debate regarding the impact of overlapping surgery on patient safety.
