Warfarin Patient Self-management Implementation in the US Healthcare System

Summary

In the US, patients receiving warfarin therapy are rarely allowed to engage in patient self-management (PSM) which is less burdensome, less expensive, and safer than standard clinic-directed warfarin management. The long-term objective of our application is to improve the safety of ambulatory warfarin therapy through increasing the implementation of PSM.
