Scientists Warn There’s One Day Of The Week You Should ‘Never’ Have Surgery
At first, this might seem surprising. After all, if you need an operation, the most important thing is getting it done as soon as possible so you can recover and move on with your life. The day of the week shouldn’t matter, right?
Well, according to a new study, patients who undergo surgery on a certain day face a noticeably higher risk of dying compared to those treated on other days.

This phenomenon, known as the ‘weekend effect,’ is believed to be linked to fewer senior medical staff being on duty over the weekend. This is a crucial period when post-surgery monitoring and follow-up care can make a big difference in a patient’s recovery.
Additionally, the study highlights that hospitals tend to have limited access to essential services like scans and lab tests on Saturdays and Sundays, which could contribute to the increased risk.
He further emphasized: “It is important for health care systems to assess how this phenomenon may impact their practices to ensure that patients receive excellent care irrespective of the day.”
For the study, researchers analyzed data from nearly 430,000 patients who had surgery in Ontario, Canada, between 2007 and 2019.
Aside from the reduced presence of senior staff over the weekend, researchers pointed out other factors that could be influencing these results.
They noted: “Furthermore, weekend teams may be less familiar with the patients than the weekday team previously managing care.”

“Further study is needed to understand differences in care that may underpin these observations and ensure that patients receive high-quality care regardless of the day of the week,” they added.
