Multidisciplinary Expert Guidance for the Management of Severe Bleeding on Oral Anticoagulation: An Algorithm for...

Area of Science:

• Internal Medicine
• Hematology
• Emergency Medicine
• Clinical Pharmacy
• Neurology
• Gastroenterology
• Thrombosis

Background:

• Oral anticoagulants (OACs) are widely prescribed but associated with frequent, severe bleeding complications.
• These bleeding events lead to significant emergency department visits, hospitalizations, and substantial short-term mortality, particularly intracranial hemorrhages (up to 50%).
• Current management lacks a standardized, multidisciplinary approach for acute severe OAC-related bleeding.

Purpose of the Study:

• To develop a practical, evidence-based protocol for the multidisciplinary management of acute severe OAC-related bleeding.
• To provide clinicians with an actionable algorithm for point-of-care use.
• To improve identification of high-risk patients and optimize supportive, reversal, and hemostatic therapies.

Main Methods:

• Convened a multidisciplinary expert panel (emergency medicine, gastroenterology, internal medicine, hematology, neurology, pharmacy, thrombosis).
• Conducted a literature review to inform practical guidance.
• Developed a management algorithm for acute severe OAC-related bleeding.

Main Results:

• The study outlines a comprehensive protocol for managing OAC-related bleeding.
• A point-of-care algorithm is provided to guide clinical decision-making.
• The protocol emphasizes rapid risk assessment, optimized supportive care, source control, and judicious use of reversal/hemostatic agents.

Conclusions:

• A structured, multidisciplinary approach is crucial for effectively managing severe OAC-related bleeding.
• The developed protocol and algorithm can assist clinicians in improving patient outcomes.
• Timely and appropriate intervention can mitigate the high mortality associated with these bleeding events.
