Patients who undergo surgeries in the evening or night have an increased risk of complications when compared to patients whose surgeries took place earlier in the day, according to a study published in Neurosurgery.

Researchers investigated all neurological surgeries performed in the University of Michigan Health System between 2007 and 2014 and included 15,807 patients.

The study showed that the odds of a complication were increased by more than 50 percent for procedures with start times between 9 p.m. and 7 a.m. Chances of complications for longer surgeries in later time periods were even higher.

Earlier studies of coronary angioplasty, orthopedic surgery, transplant surgery, colorectal surgery, and cardiac arrest patients had found a relationship between night surgeries and worse outcomes, but a similar study had not been conducted for neurological procedures.

The analysis demonstrated that a patient's odds of having a complication increased significantly at night even after accounting for whether the case was an emergency versus elective procedure or if the patient had other chronic conditions.

The researchers acknowledged that there could be other explanations for higher rates of complications, including the possibility that patients treated after normal hours are sicker than those treated during normal hours.

"We need to continue to study this relationship as we aim to minimize surgery related complications," said lead author Aditya Pandey. "Could it mean that health systems need to invest more with respect to increasing the number of surgical teams and operating rooms to allow for greater proportion of surgeries to be performed during day hours and that urgent cases should be stabilized and performed during day hours? These are important questions that must be raised as we continue to solidify the relationship between surgical start time and surgical complications."

Studies have also shown that patients admitted on the weekends have a higher 30-day mortality risk than those admitted during the week. According to a study published in the Journal of Neurosurgery: Pediatrics, the "weekend effect" has been observed among patients admitted with many diagnoses including myocardial infarction, pulmonary embolism, ruptured abdominal aortic aneurysm, stroke, peptic ulcers, and pediatric surgery.
