Why the study?
Real-world experience with perioperative DOAC management is scarce, and no prior study had linked bridging therapy or DOAC-free time with outcomes.
Does bridging therapy and prolonged DOAC-free time increase complications in adult patients on DOACs requiring surgery?
Observational (n=901)
Yes
Does bridging therapy and prolonged DOAC-free time increase complications in adult patients on DOACs requiring surgery?
Odds Ratio: 4.2 (95% CI 1.4–12.3)
In patients on DOACs undergoing surgery, bridging therapy increases bleeding risk without reducing thrombotic events, and prolonged DOAC interruption increases thrombotic risk.
Introduction There is scarce real-world experience regarding direct oral anticoagulants (DOACs) perioperative management. No study before has linked bridging therapy or DOAC-free time (pre-plus postoperative time without DOAC) with outcome. The aim of this study was to investigate real-world management and outcomes. Methods RA-ACOD is a prospective, observational, multicenter registry of adult patients on DOAC treatment requiring surgery. Primary outcomes were thrombotic and hemorrhagic complications. Follow-up was immediate postoperative (24–48 hours) and 30 days. Statistics were performed using a univariate and multivariate analysis. Data are presented as odds ratios (ORs [95% confidence interval]). Results From 26 Spanish hospitals, 901 patients were analyzed (53.5% major surgeries): 322 on apixaban, 304 on rivaroxaban, 267 on dabigatran, 8 on edoxaban. Fourteen (1.6%) patients suffered a thrombotic event, related to preoperative DOAC withdrawal (OR: 1.57 [1.03–2.4]) and DOAC-free time longer than 6 days (OR: 5.42 [1.18–26]). Minor bleeding events were described in 76 (8.4%) patients, with higher incidence for dabigatran (12.7%) versus other DOACs (6.6%). Major bleeding events occurred in 17 (1.9%) patients. Bridging therapy was used in 315 (35%) patients. It was associated with minor (OR: 2.57 [1.3–5.07]) and major (OR: 4.2 [1.4–12.3]) bleeding events, without decreasing thrombotic events. Conclusion This study offers real-world data on perioperative DOAC management and outcomes in a large prospective sample size to date with a high percentage of major surgery. Short-term preprocedural DOAC interruption depending on the drug, hemorrhagic risk, and renal function, without bridging therapy and a reduced DOAC-free time, seems the safest practice.

Ferrandis et al. (2020) conducted an observational in DOAC treatment requiring surgery (n=901). Perioperative bridging therapy vs. No bridging therapy was evaluated on Thrombotic and hemorrhagic complications (OR 4.2, 95% CI 1.4-12.3).
