Perioperative medicine & outcomes
Surgical time, peri-operative major adverse cardiac and cerebral events and hospital stay in noncardiac surgery: insights from 7-day service implementation: A retrospective case-control study
Authors' conclusion
Night-shift surgery was an independent risk factor for peri-operative MACCE in noncardiac surgery patients. The 7-day service policy reduced night-shift procedures and increased those at weekends, without increasing the risk of MACCE. It was also associated with shorter hospital stays.
