An Education Program for Patient Self-Management of Warfarin.

INTRODUCTION
Although improved anticoagulation therapy outcomes have been demonstrated in clinical trials evaluating warfarin patient self-management (PSM) programs, these studies did not provide detailed information regarding PSM program development and patient training.


OBJECTIVE
To evaluate the feasibility of and methods for developing and administering an education program to support a novel pilot warfarin PSM program.


METHODS
Patients receiving warfarin for atrial fibrillation were recruited to participate in a prospective, intervention-only, open-label pilot PSM program that released venipuncture international normalized ratio results to patients via a secure, online Web site. To support the pilot, a warfarin PSM education program with a dosing algorithm was developed and delivered to patients during a two-hour classroom session.


MAIN OUTCOME MEASURE
A comparison of participants' PSM competency test scores before and after attending the PSM program.


RESULTS
Forty-four patients attended the education program. The mean age of participants was 71 years and 50% were women. Patients declining study participation were older (p = 0.003) and had a greater burden of chronic disease (p = 0.005) than participants. Following PSM training, the mean competency score improved from 55.8% to 88.8% (p < 0.001), and the proportion achieving a passing score increased from 34.9% to 95.3% (p < 0.001). In the poststudy survey, 100% of responders perceived that PSM training prepared them to self-manage warfarin, and 92.9% of responders were comfortable changing warfarin doses on their own.


CONCLUSION
Developing and administering a warfarin PSM education program for patients with atrial fibrillation was feasible. Improvement in PSM competency and high levels of self-reported comfort with warfarin PSM were identified.
