Reading Level and Suitability Assessment of Heart Failure Education in a Mobile App “CHF Info App”
Education at the time of diagnosis or at discharge after an index illness is a vital component of improving outcomes in congestive heart failure (CHF). About 90 million Americans have limited health literacy and have a readability level at ≤ 5th grade, which could affect their understanding of education provided at the time of diagnosis or discharge from hospital.
To assess the suitability and readability level of a mobile phone application “CHF Info App”.
A descriptive design was used to assess the reading level and suitability of patient education materials included in CHF Info App. The Suitability assessment of patient education material included in the CHF Info App was assessed independently by the authors using the 26-item of the Suitability Assessment of Materials (SAM) tool. The reading grade level for each of the ten CHF educational module included in the CHF Info App was assessed using the comprehensive online Text Readability Consensus Calculator based on the seven most common readability formulas (Flesch Reading Ease score, Gunning Fog, Flesch-Kincaid Grade Level, The Coleman-Liau Index, The SMOG Index, Automated Readability Index, and Linsear Write Formula). The reading level included text scale, ease of score, and the corresponding grade level.
The education materials included in the CHF Info App ranged from fifth grade to eighth grade reading level with the mean of sixth grade level that is recommend by the American Medical Association. The suitability assessment (SAM) result demonstrated adequate to superior levels in all components assessed including content, appearance, visuals, layout and design with a total score at 77% indicating superior suitability.
The authors conclude that the CHF Info App will be suitable and meet the health literacy level recommended for American adult learners. Further testing of the CHF Info App in a longitudinal study is warranted to determine improvement in CHF knowledge. Clinical Trial: None
