The reduction in COVID-19 risk persisted for longer than previously known, for a period of 13 months after surgery. The study’s findings are published in Open the JAMA network.
The researchers used electronic health record data from 3,997 adult surgical patients with a history of SARS-CoV-2 infection who had undergone surgery at (VUMC extension) (VUMC) since May. 3, 2020 to December 2021. The time from COVID diagnosis to surgery was an average of 98 days.
COVID-19: Perioperative risk assessment
The team analyzed the composite odds of various cardiovascular problems within 30 days of surgery: deep vein thrombosis, pulmonary embolism, cerebrovascular accident, myocardial damage, trauma acute kidney failure and death.
It then continued to decline gradually over the next 10 months, reaching about 8% 400 days after COVID-19 diagnosis. The rate of risk reduction was not affected by the patient’s COVID-19 vaccination status.
“Compared to previous population studies on this issue, our study stands out for its follow-up,” said Robert Freundlich, MD, MSCI, associate professor of Anesthesiology and Biomedical Informatics, who led the study. wider surgical outcomes and using a longer time period from a COVID-19 diagnosis.” studied with intensive care medical doctor John Bryant.

“As we were in the middle of our study, based on lung outcomes after surgery, a medical association made a recommendation to delay surgery after COVID-19 for up to 12 weeks for those who have,” said Freundlich. more severe cases of COVID-19”. “Meanwhile, for this series of cardiovascular problems, in our data, we were surprised to see that a trend in risk reduction was still discernible more than a year after a COVID-19 diagnosis. .”
“In a given patient’s case, many considerations can influence the best time for surgery to take place, and our results provide further indication that doctors and patients will do a good job. put closeness to COVID-19 in their minds.”
