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

Area of Science:

• Cardiology
• Pharmacology
• Clinical Medicine

Background:

• Emerging evidence indicates peri-procedural bridging during warfarin interruptions may elevate bleeding risk without preventing thromboembolic events.
• Optimizing anticoagulant management is crucial for patient safety during invasive procedures.

Purpose of the Study:

• To evaluate the impact of implementing a peri-procedural anticoagulant management risk assessment tool on warfarin bridging practices.
• To assess changes in bleeding and thromboembolic events following the tool's implementation.

Main Methods:

• A retrospective, pre-post observational study was conducted in an outpatient anticoagulation clinic.
• The study evaluated 149 adult patients requiring warfarin interruption for invasive procedures.
• Key outcomes included the proportion of patients receiving bridging, major bleeding, and thromboembolic events.

Main Results:

• Bridging recommendations decreased significantly from 60% pre-intervention to 39.3% post-intervention (p=0.012).
• No significant differences in major bleeding or thromboembolic events were observed between groups.
• Patients receiving bridging showed numerically higher bleeding rates compared to those not bridged.

Conclusions:

• Implementation of the risk assessment tool led to a statistically significant reduction in peri-procedural warfarin bridging.
• The reduction in bridging was achieved without an increase in thromboembolic events.
• Further research is needed to refine bridging strategies and assess the impact of such tools on patient outcomes and healthcare costs.
