Warfarin-sodium (Coumadin) is one of the most commonly used medications today. It is used to prevent the formation of dangerous blood clots. Unfortunately, patient response to this medication is extremely variable, making it difficult for clinicians to prescribe an appropriate dose for every patient. This makes warfarin dangerous. A number of physiological, genetic, and dietary factors interact with warfarin to determine how a patient responds to the medication. As a result, management of warfarin requires frequent laboratory monitoring and dose adjustments to maintain effectiveness while minimizing risk of bleeding.
However, some clinicians have allowed select patients to monitor and adjust their own warfarin dose. It may be possible for software, based on the Case-Based Reasoning (CBR) technique, to provide personalized suggestions that help patients make decisions when managing their own therapy. CBR is a method of making decisions by applying solutions that were effective in previous experiences to new, but similar situations. Join us in a discussion about the potential use of a CBR system in helping patients manage their own warfarin dose.
