Assessing readability and comprehension of web-based patient education materials by American Heart Association (AHA) and CardioSmart online platform by American College of Cardiology (ACC): How useful are these websites for patient understanding?

Cardiovascular diseases (CVD) are a leading cause of morbidity & mortality worldwide. Patient education materials help patients understand the disease and its management. Health literacy is an important challenge that may contribute to health inequities and disparities. The National Institute of Health and American Medical Association recommend patient education materials to be ≤6th-grade reading level. Objective: To evaluate readability and comprehension of patient education materials related to CVD, available at the American Heart Association (AHA) & CardioSmart web platform by the American College of Cardiology (ACC) websites. Method: -value ≤ 0.05 was significant. Results: Sixty-three web pages of patient education materials (AHA 24, ACC 39) were reviewed in June 2022. Mean ± standard deviation (SD) FKRE was 54.9 ± 6.8 for all the web pages. FKRE 50-60 equates to "fairly difficult to read." Mean ± SD FKGL was 10.0 ± 1.3. AHA patient education materials content was significantly more difficult to read and comprehend, were longer, and had more complex words than ACC patient education materials. Conclusions: CVD-related patient education materials available online through leading national organizations are not congruent with the recommendations from national healthcare organizations. They are not as user-friendly as they can be. Urgent recognition of the gaps and unmet needs are indicated to optimize patient health literacy.
