WarfarinGuide 2.2

Warfarin Guide provides three essential resources for systematic and evidence-based anticoagulation management with Warfarin. The tool first examines recommendations on indications, INR targets, and treatment duration based on the American College of Chest Physicians 8th Edition guidelines on Antithrombotic and Thrombolytic Therapy from 2008, with updates for the 2012 guideline. Additionally, it offers a protocol for Warfarin dose adjustment based on INR results and a discussion on protocols for Warfarin initiation. These comprehensive resources are sourced from point-of-care guides in family medicine literature and the 2012 ACCP guideline. The app also includes guidance on peri-operative Warfarin management, directing users to comprehensive resources for managing all anticoagulants and antiplatelet agents around surgery.

The app addresses common questions such as:

• Which artificial heart valves require higher levels of anticoagulation?
• How to respond to an INR of 7.4?
• This patient needs Warfarin; how to initiate treatment?
• When to recheck the INR if adjusting the total weekly Warfarin dose down by 5%?
• When and how to administer Vitamin K to reverse Warfarin anticoagulation?

Warfarin Guide is designed for practicing clinicians involved in Warfarin anticoagulation, including internists, cardiologists, family physicians, nurses, pharmacists, PAs, NPs, resident physician trainees, and medical students. The developer seeks feedback for enhancing the tool's quality.
