Peri-procedural antithrombotic management: time to burn the bridge?

Emerging evidence suggests the use of peri-procedural bridging during interruptions in warfarin therapy increases bleed risk without reducing thromboembolic events. We implemented a peri-procedural anticoagulant management risk assessment tool in a single, outpatient anticoagulation clinic within an academic teaching institution. In this retrospective, pre-post observational study, we evaluated adults who required an interruption in warfarin therapy for an invasive procedure.
