Better, cheaper, more convenient

Better, cheaper, more convenientPeople who take Coumadin (warfarin) have to have their blood tested and medication adjusted regularly. Too high a does can kill, too low a dose doesn't work, and there's limited room for error. Typically patients go to the Coumadin clinic every few weeks, have their blood drawn and their meds adjusted. But a new study confirms earlier evidence that home testing can be a superior alternative.Patients who test at home test more often, which helps them keep their INRs in range through more frequent dosage adjustments. It's more convenient and cheaper, too.See Cost-effectiveness of self-managed versus physician-managed oral anticoagulation therapy in CMAJ.
