Evaluation of an educational programme for patients taking warfarin

Area of Science:

• Pharmacology
• Patient Education
• Vascular Surgery

Background:

• Warfarin therapy requires careful patient management to ensure efficacy and safety.
• Existing patient education for warfarin is often unstructured, potentially leading to suboptimal outcomes.
• Assessing patient knowledge and satisfaction is crucial for effective therapeutic management.

Purpose of the Study:

• To compare the outcomes of a structured warfarin patient education program with an unstructured program.
• To evaluate the impact of structured education on patient knowledge, satisfaction, and warfarin therapy complications.
• To examine prothrombin time results in relation to patient education methods.

Main Methods:

• A comparative study involving 23 patients in a structured education group and 10 patients in an unstructured (usual care) group.
• Data collection included patient interviews using guides to assess knowledge and satisfaction at predischarge, 1 month, and 3 months post-discharge.
• Incidence of complications and prothrombin time results were monitored.

Main Results:

• The structured program group demonstrated significantly greater knowledge of warfarin therapy elements at predischarge.
• Both groups reported satisfaction with information received, and most patients experienced no complications.
• Prothrombin times were frequently outside the therapeutic range (≥60% of the time) for a significant portion of patients in both groups.
• Structured education provided specific safety instructions that were particularly impactful.

Conclusions:

• Structured patient education programs are vital for achieving safe and effective warfarin therapy.
• Further research is warranted to explore knowledge changes over time and the link between education and optimal warfarin control.
• Enhancing patient understanding through structured programs can improve warfarin management outcomes.
