Researchers from Houston Methodist Hospital, UCLA, the University of Toronto, and other institutions recently conducted a study to address the long-standing concern about the impact of scheduling surgeries on Fridays. The analysis, which involved data from 429,691 patients, revealed that individuals who underwent surgery on Fridays experienced higher rates of complications, readmissions, and mortality in the days and months following their procedures compared to those who had surgeries on other days of the week.
The concept of the “weekend effect” in healthcare refers to the phenomenon where patient outcomes are poorer when medical care is provided over weekends. This effect can be attributed to factors such as variations in hospital staffing, access to specialists, and care processes during weekends. In the context of surgery, the weekend effect has raised concerns about the quality of care provided to patients undergoing procedures on Fridays.
The fear of the weekend effect is not unfounded, as previous studies have yielded conflicting results regarding the impact of scheduling surgeries on Fridays. Some studies have reported increased mortality rates for Friday surgeries, while others have found no significant patterns. Given the persistent concerns and fears surrounding the weekend effect, a comprehensive investigation was necessary to evaluate its influence on postoperative outcomes across various procedures and timeframes.
In the study titled “Postoperative Outcomes Following Preweekend Surgery,” published in JAMA Network Open, researchers conducted a retrospective analysis of data from 429,691 adults who underwent common surgical procedures in Ontario, Canada, between 2007 and 2019. The study compared outcomes for patients who had surgery one day before the weekend (Friday or pre-holiday) to those who had surgery one day after the weekend (Monday or post-holiday).
The analysis revealed that patients in the pre-weekend surgery group had longer hospital stays compared to those in the post-weekend group. Additionally, individuals who underwent surgery on Fridays had a 5% higher likelihood of experiencing a combination of mortality, complications, and readmissions within 30 days post-operation. The risk of death was 9% higher at 30 days and continued to increase over time, with mortality rates 10% higher at 90 days and 12% higher at one year.
Interestingly, the study found that scheduled or elective procedures performed before the weekend were associated with worse outcomes, while urgent unplanned surgeries showed slightly better outcomes when conducted before the weekend. The researchers noted variations in hospital staffing, reduced access to specialists, and differences in perioperative care processes as potential contributors to these trends.
While the study did not pinpoint the exact causes of the disparities in surgical outcomes, it emphasized the need for further research to ensure high-quality postoperative care regardless of the day of the week. The findings underscore the importance of addressing concerns and fears related to the weekend effect in surgical settings to optimize patient outcomes and enhance the quality of care provided to individuals undergoing surgeries.
