Managing patients on warfarin therapy in a cost-effective way can be a challenge for physicians because of a narrow therapeutic dosing range, inefficient office workflow models and other factors.
But there is a solution - one that can benefit both physicians and their patients.
Systematic anticoagulation management (SAM) is a patient-focues approach that utilizes PT/INR testing at the point of care rather than through an outside lab. Multiple studies have shown that this approach may increase the time patients are in range and reduce adverse events. 1,2,3,4
Improved patient care. By improving consistency in results, SAM has been shown to increase patients' average time in therapeutic range by as much as 97%2 and significantly reduce thromboembolic and hemorrhagic events - as well as the costs associated with them. 2,5,6,7
