TO THE EDITOR:
The paper by Beyth and colleagues (1) described a clever innovation that attempts to circumvent the delay that bedevils the process of transmitting the results of prothrombin testing from the laboratory to the provider, who then chooses the appropriate warfarin dose. Indeed, this home monitor is similar to the glucometer used by patients with diabetes.
While applauding this innovation, however, I wish to reiterate my observations (2) favoring extra monitoring for patients taking long-term warfarin therapy and suggesting that the fecal occult blood test and tests for hematocrit are two additional monitoring tools that could improve patient outcomes when used in conjunction with prothrombin activity (INR) measurements. Indeed, these tests are routinely used to screen patients for anticoagulant therapy (3).
