Can a simple and cost-free tool help family physicians to improve dosing of the blood thinner warfarin?
Warfarin is a blood thinner with a variable effect and requires regular blood monitoring and dose adjustments. Some family practices do not have the facilities or funding to use commercial tools than can assist with stabilizing the effect of warfarin. The investigators will test whether a simple and cost-free dosing tool can help these practices to improve warfarin management. If this simple tool improves warfarin management, it will be freely available for practices in Canada and around the world. This will help physicians who have no access to more costly and/or complicated tools improve their warfarin dosing practice in a systematic fashion, and thereby maximize the health benefit of warfarin.
