In a first that depicts cyclic impacts on hospital deaths in patients after a surgery, a new research claims that the death risk is highest in surgeries conducted on weekends, in the month of February or in the afternoon.
After analyzing the data from around 218,758 patients, the researchers concluded that the surgery carried on in the afternoon is associated with 21% increased death risk as compared to the surgery carried on at other day times. Moreover, the surgery conducted at the weekend was associated with a 22% increased death risk as compared to the surgery in weekdays.
It was also found that February was the month which had the highest death risk, as surgery conducted in February was associated with a 16% increased death risk as compared to the surgery in the rest of the months. Several factors might have influenced these findings. Felix Kork of Charite-University Medicine Berlin, said, “For example, it may be that standard of care differs throughout the day and between weekdays and weekends.”
He further explained, “Although we controlled for risk factors including emergency surgery in our study, it may very well be that the patients treated in the afternoon and on the weekends were more severely ill. We need more data to draw conclusions regarding seasonal variation in postoperative outcome.”
The research was first presented at ‘Euroanaesthesia 2014‘, a seminar held in Sweden on May 31 to June 3.
