Patient Interpretations of Heart Failure Symptom Recognition and Self-Management Using Vignettes: A Pilot Study.

Area of Science:

• Cardiology
• Medical Education
• Health Psychology

Background:

• Heart failure (HF) presents a substantial symptom burden and high hospitalization rates.
• Effective self-management, including symptom recognition and behavioral changes, is critical for HF patients.
• Current educational methods often fall short in addressing HF self-care needs.

Purpose of the Study:

• To evaluate the understandability of novel heart failure self-care vignettes.
• To assess the inter-rater reliability of these vignettes among HF patients.
• To refine an instrument for measuring knowledge of HF symptom recognition and self-management.

Main Methods:

• Cognitive interviews were conducted with five HF patients (aged 65+).
• Vignette segments and interview questions were analyzed for understandability.
• Inter-rater reliability was assessed using Cohen's kappa and percent agreement.

Main Results:

• Patients demonstrated acceptable preliminary understandability, comprehending 76% of psychological and 83% of physical vignette items.
• Moderate inter-rater reliability was observed, with Cohen's kappa values of 0.39 (psychological) and 0.43 (physical).

Conclusions:

• Heart failure self-care vignettes show potential as a tool for assessing patient knowledge.
• Cognitive interviewing effectively evaluated vignette interpretation for future research.
• Further development and validation of these vignettes are warranted.
