Key clinical point: RBC transfusions were associated with development of postoperative venous thromboembolism (VTE).
Major finding: Patients who received perioperative RBC transfusions had significantly increased odds of developing VTE in the 30-day postoperative period (adjusted odds ratio, 2.1; 95% confidence interval, 2.0-2.3), compared with patients who did not receive transfusions.
Study details: An analysis of prospectively collected North American registry data including 750,937 patients who underwent a surgical procedure in 2014.
Disclosures: The study was funded in part by grants from the National Institutes of Health and Cornell University, New York. The researchers reported having no conflicts of interest.
