N2 - The Perioperative Anticoagulation Use for Surgery Evaluation (PAUSE) study prospectively evaluated a prespecified periprocedural-interruption strategy of direct oral anticoagulants (DOACs) among patients with atrial fibrillation. Logistic regression analyses were performed to identify clinical parameters associated with residual DOAC levels ≥30 ng/mL or ≥50 ng/mL. Patients undergoing low-bleed-risk procedures were more likely to have residual levels of ≥30 ng/mL and ≥50 ng/mL. For low-risk procedures, age ≥75 years, female sex, a creatinine clearance (CrCl) <50 mL/min, and an interruption of <36 hours were associated with a greater likelihood of levels ≥30 ng/mL, whereas age ≥75 years, female sex, a CrCl of <50 mL/min, and standard DOAC dosing were associated with levels ≥50 ng/mL. For high-risk procedures, weight of <70 kg, CrCl <50 mL/min, and standard DOAC dosing were associated with residual levels ≥30 ng/mL, whereas female sex was associated with levels ≥50 ng/mL. For low-risk procedures, apixaban was associated with a higher likelihood of levels ≥30 ng/mL as compared with dabigatran (P = .0019) and of levels ≥50 ng/mL when compared with rivaroxaban (P = .0003). For high-risk procedures, apixaban was marginally associated with a higher likelihood of residual levels ≥30 ng/mL when compared with dabigatran (P = .05), whereas rivaroxaban was associated with a higher likelihood of levels ≥30 ng/mL as compared with apixaban. Further study is required to determine whether adjustments to perioperative plans based on these clinical parameters could result in a lower risk of residual DOAC levels. The PAUSE trial was registered at www.clinicaltrials.gov as #NCT2228798.
