Evaluating Patients' Understanding of Printed Warfarin Medication Information

Area of Science:

• Pharmacology
• Patient Education
• Health Literacy

Background:

• Warfarin is a critical, high-risk anticoagulant medication.
• Effective patient education is vital for safe warfarin management.
• Existing educational materials may not adequately address patient comprehension.

Purpose of the Study:

• To evaluate patient understanding of warfarin instructions and medication management.
• To assess comprehension of the Food and Drug Administration's (FDA) warfarin medication guide.
• To gather patient recommendations for improving warfarin information delivery.

Main Methods:

• Qualitative interviews with 49 patients initiated on warfarin therapy within the past year.
• Interviews conducted at two hospital-based outpatient primary care settings.
• Focus on understanding of medication instructions, management, and FDA guide content.

Main Results:

• A significant portion of patients experienced difficulties understanding warfarin information, including diet and provider contact guidelines.
• 19% of patients faced numeracy challenges related to warfarin.
• Patients suggested enhanced methods like more graphics, in-person counseling, and multilingual translations.

Conclusions:

• Gaps exist in patient comprehension of warfarin therapy, indicating current educational approaches are insufficient.
• The FDA warfarin medication guide alone does not ensure adequate patient understanding.
• Incorporating patient-suggested improvements can enhance warfarin education for diverse learning needs.
