New study shows warfarin weekly self-testers achieve better control with management by exception protocol

April 02, 2014

In a study recently published in Nursing 2014, atrial fibrillation patients on warfarin therapy who self-tested their coagulation (via international normalized ratio [INR]) and were remanaged by their clinicians using a “Management by Exception” protocol had better warfarin control than traditional self-testers.1 The protocol, in which patients followed specific clinic-issued, written instructions for managing out-of-range INR self-test results within a predetermined safety range, also benefited clinics by reducing the need for telephone follow-up and related costs.
