Summary
The purpose of this study is to determine the feasibility, safety, and acceptability of
implementing an extended interval of INR follow-up in Veterans on a stable dose of warfarin
in the Anticoagulation Clinic at the William S. Middleton Memorial Veterans Hospital.
All participants will be provided usual care from the anticoagulation clinic, except for the
interval between INRs. If the participant continues to be on a stable dose of warfarin and
the INRs are within the goal range of 2-3 (including lab variation), follow-up visits will be
scheduled following an extended interval protocol. Patient satisfaction will be evaluated at
various points throughout the study. Additionally provider satisfaction, confidence, and
knowledge of the extended interval protocol will be analyzed. Bleeding and thromboembolic
events will be evaluated to ensure the safety of an extended follow-up interval.
