Surgeries performed by women have better results – 09/06/2023 – Health

Patients treated by female surgeons have better postoperative outcomes compared to those treated by male surgeons. At least that is the conclusion of two recent studies, carried out in Canada and Sweden and published in the specialized journal JAMA Surgery.

The Canadian retrospective study, led by Christopher Wallis of the University of Toronto, found that patients operated on by women had a lower risk-adjusted probability of adverse postoperative outcomes within 90 days (12.5% ​​versus 13.9%) and within one year (20.7% against 25%).

The results also reflected a lower mortality rate in both periods. In an interview with MedPage Today, Wallis said that while many surgical studies focus on short-term outcomes, “these long-term data parallel the short-term results.”

Wallis’s team analyzed medical complications, hospital readmissions and death rates after surgical procedures in nearly 1.2 million Ontario patients between 2007 and 2019. The records included 25 different operations on the heart, brain, bones, blood vessels and other organs. .

Women would dedicate more time

On the other hand, the Swedish study, led by My Blohm, from the Karolinska Institutet, in Stockholm, focused on the so-called cholecystectomy, a surgical procedure that consists of removing the gallbladder. The bottom line: patients treated by female surgeons had fewer complications and shorter hospital stays.

Data from 150,000 Swedish patients revealed that people undergoing treatment performed by female surgeons suffered fewer complications and spent less time in hospital than those treated by men. Female surgeons also devoted more time to surgeries, which might suggest that working at a slower pace could result in better post-operative care.

The results suggest that the surgical technique and the assumption of risks may explain some of the observed differences. Blohm called attention, however, to the need for such conclusions to be seen with caution, since they are based on observational studies.

Both studies generated reflections on how surgeries are performed. “Our goal is not to blame,” Wallis said. “Our goal is to really understand the delivery of surgical care so that we can improve care for every patient treated by every physician.”

The researcher also said that it is not a question of replacing all male surgeons with women, but of understanding the differences in the way the profession is carried out in order to improve care.

lessons for men

Blohm, for his part, evoked a widespread belief in some countries that male surgeons are superior to female surgeons. “Interestingly, most previously published studies indicate that female surgeons are at least as good as male surgeons, or as in this case, even slightly better.”

The implications of such findings are clear and may inspire reflection on what men can learn from their female counterparts. “Men and women differ in the way they practice medicine. Adopting some practices that are more common among women will likely improve outcomes for my patients,” said Wallis.
