Everybody’s working for the weekend, which, according to a new study, is incidentally the worst time of the week to undergo surgery. A paper published in the JAMA Network on March 4, 2025, concludes that patients experience worse outcomes during the weekends, as compared to weekdays. This phenomenon is known as the “weekend effect” and the study, which examined 429,691 patients in Ontario, Canada, determined that people whose surgeries began directly before the weekend “experienced a statistically significant increase in the composite outcome of death, complications, and readmissions at 30 days, 90 days, and 1 year.”
