Readability of “Dear Patient” device advisory notification letters created by a device manufacturer

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

We examined the readability and comprehension of 63 patient education materials (accessed June 2022) using: (a) Flesch Kincaid Readability Ease (FKRE): measures readability (0-100, goal > 70), (b) Flesch Kincaid Grade Level (FKGL) (goal = grade 7). We compared the AHA and ACC scores using descriptive and t-tests. P-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.

Health Literacy: Readability of ACC/AHA Online Patient Education Material

OBJECTIVES

To determine whether the online patient education material offered by the American College of Cardiology (ACC) and the American Heart Association (AHA) is written at a higher level than the 6th-7th grade level recommended by the National Institute of Health (NIH).

METHODS

Online patient education material from each website was subjected to reading grade level (RGL) analysis using the Readability Studio Professional Edition. One-sample t testing was used to compare the mean RGLs obtained from 8 formulas to the NIH-recommended 6.5 grade level and 8th grade national mean.

RESULTS

In total, 372 articles from the ACC website and 82 from the AHA were studied. Mean (±SD) RGLs for the 454 articles were 9.6 ± 2.1, 11.2 ± 2.1, 11.9 ± 1.6, 10.8 ± 1.6, 9.7 ± 2.1, 10.8 ± 0.8, 10.5 ± 2.6, and 11.7 ± 3.5 according to the Flesch-Kincaid grade level (FKGL), Simple Measure of Gobbledygook (SMOG Index), Coleman-Liau Index (CLI), Gunning-Fog Index (GFI), New Dale-Chall reading level formula (NDC), FORCAST, Raygor Readability Estimate (RRE), and Fry Graph (Fry), respectively. All analyzed articles had significantly higher RGLs than both the NIH-recommended grade level of 6.5 and the national mean grade level of 8 (p < 0.00625).

CONCLUSIONS

Patient education material provided on the ACC and AHA websites is written above the NIH-recommended 6.5 grade level and 8th grade national mean reading level. Additional studies are required to demonstrate whether lowering the RGL of this material improves outcomes among patients with cardiovascular disease.

Implantable Medical Device Website Efficacy in Informing Consumers Weighing Benefits/Risks of Health Care Options

As more individuals turn to the Internet for health-related information and technology increases the availability and use of implantable medical devices (IMDs), the websites marketing these devices will increase. Healthy People 2020 mandates increased understandability and usability of health-related websites. This project used social cognitive theory (SCT) and health literacy constructs from the Institute of Medicine and National Institutes of Health to analyze eight IMD websites. Despite current recommendations, none of the websites considered for this study offered content of an appropriate reading level in conjunction with the United States average of eighth grade, and 75% of the sites failed to satisfy more than one health literacy construct. Most of the websites lacked many of the SCT constructs. More attention is needed to improve the usability of these and future IMD websites to simultaneously meet the goal of marketing IMDs and the Healthy People 2020 goals to educate patients and promote public health.
