Evaluating the most popular diabetes websites in the USA: a content analysis

Over 1.5 million Americans are diagnosed with diabetes every year, and the majority of them go online to learn about their condition. Unfortunately, the online diabetes landscape is crowded, and the quality of website content is unknown-guidance for patients and healthcare providers regarding online diabetes information is needed. To address this, nine of the top diabetes websites in the USA were identified through a comprehensive, multiple-query search and a content analysis was conducted. Two coders, with high inter-coder reliability, evaluated these websites on six factors: (i) Design; (ii) Credibility; (iii) Accessibility; (iv) Literacy; (v) Engagement; and (vi) Diabetes Content. The analysis revealed that the websites presented most of the assessed design features. Few of the sites scored well on the credibility assessment, while the majority of sites did not note an author, editor or reviewer. With regard to accessibility, less than half of the items we assessed were met. Furthermore, the websites possessed wide variability in literacy, with an average readability grade level of 8.8. Most of the websites fared well in engagement, demonstrating multiple avenues to interact with the organization. All of the websites provided basic information regarding diabetes, but many did not include information for caregivers, providers or insurance information. In conclusion, patients and their family members will continue to seek online information about diabetes, its effects and treatment options. Therefore, this multiple-metric evaluation provides essential information for these individuals, and healthcare providers, who can now give better informed website recommendations to their patients and families.
