Abstract 249: Online Health Information for Myocardial Infarction: Trusted Source or Fake News?

Abstract

Objective: As the internet is a leading destination for health information for patients, there is a need for this information to be accurate and easy to understand. In this study, we assessed the quality and readability of online health related information for myocardial infarction (MI) directed towards patients. Methods: Websites were collected from 3 search engines (Google, Yahoo! and Bing) using the search term “Heart Attack” on a newly installed Mozilla Firefox browser. The first 30 websites from each engine were selected and those belonging to advertisements, new articles and physician oriented sites were excluded. The resulting sites were assessed for quality using the DISCERN instrument via 2 physician investigators knowledgeable in MI and blinded to each other’s results; following this, the results were discussed amidst the team to agree on a coalesced score for each website. Health On the Net (HONcode) was also used as an added measure to assess quality. Readability was assessed using the Flesch-Kincaid Readability Ease (FLRE) and the Flesch-Kincaid Grade level (FLGL) tool. Results: Overall, 24 websites were assessed. The average overall quality for DISCERN was 2.58 out of 5 with a median of 2.5 while the average total DISCERN score was 37.75 out of 80; the highest total quality among them being 61 out of 80. Only 29.17% (7 of 24) of the websites were HONcode certified. The average FLRE was 59.07 out of 100, while the average FLGL was 7.28 with the lowest grade level being 5.20. Conclusion: Patient health related information, on average, were of lower quality, while those higher quality websites were deemed less readable and needed a higher level of education to understand. The average reading grade level was that of the 7 th grade which is lower than what the average American reads at (8 th grade). The highest quality website based on total DISCERN score was from Wikipedia, however FLRE and FLGL tell us it was also harder to comprehend for the average American. Going forward there are important opportunities to improve the quality of online health related information for MI, in order to remain a trusted source of medical information for patients.
