Warfarin self-monitoring proves safe

HOME monitoring of INR and self-adjustment of warfarin dose using an algorithm is safe, cost-effective and may reduce the risk of thromboembolism, researchers say.

A systematic review of 26 European and American randomised controlled trials comparing self-monitoring with standard INR monitoring was conducted by researchers from the University of Aberdeen. It included 8760 adults and children on long-term warfarin, mainly for atrial fibrillation or artificial heart valves.
