Readability of online monkeypox patient education materials: Improved recognition of health literacy is needed for dissemination of infectious disease information

Background

Health literacy is key to navigating the current global epidemic of misinformation and inaccuracy relating to healthcare. The American Medical Association (AMA) suggests health information should be written at the level of American sixth grade. With the monkeypox outbreak being declared a Public Health Emergency of International Concern (PHEIC) in July 2022, we sought to assess the readability of online patient education materials (PEMs) relating to monkeypox to see if they are at the target level of readability.

Methods

A search was conducted on Google.com using the search term ‘Monkeypox’. The top 50 English language webpages with patient education materials (PEMs) relating to monkeypox were compiled and categorised by country of publication and URL domain. Readability was assessed using five readability tools: Flesch Reading Ease Score (FRES), Flesch-Kincaid Grade Level (FKGL), Gunning Fog Index (GFI), Coleman-Liau Index (CLI), and, Simple Measure of Gobbledygook Index (SMOG). Unpaired t-test for URL domain, and one-way ANOVA for country were performed to determine influence on readability.

Results

Three of the five tools (FRES, GFI, CLI) identified no webpages that met the target readability score. The FKGL and SMOG tools identified one (2%) and two (4%) webpages respectively that met the target level. County and URL domain demonstrated no influence on readability.

Conclusion

Online PEMs relating to monkeypox are written above the recommended reading level. Based on the previously established effect of health literacy, this is likely exacerbating health inequalities. This study highlights the need for readability to be considered when publishing online PEMs.
