If you have surgery in the mornings it may be to your benefit since surgical teams may tend to be fresher compared to those who have already performed surgeries throughout the day. Scheduling your surgery earlier in the week may also work the same way and possibly benefit you more.
For whatever reasons, research shows that the death rate for patients having surgery later in the week and on weekends is higher for those compared to those who have surgery earlier in the week. Furthermore, there may not be as many surgical staffers on hand at night, on weekends and on holidays compared to other times of day. Also, it may take longer to get lab results at night, on weekends and on holidays.
