Generalized pustular psoriasis: Quality and readability of online health information

Abstract

AbstractGeneralized pustular psoriasis (GPP) is a multisystem disease with potentially life‐threatening adverse effects. As patients increasingly seek health information online, and as the landscape for GPP changes, the quality of online health information (OHI) becomes progressively more important. This paper is the first of its kind to examine the quality, comprehensiveness and readability of online health information for GPP. Similar to pre‐existing studies evaluating OHI, this paper examines 5 key search terms for GPP‐ 3 medical and 2 laymen. For each search term, the results were evaluated based on HONcode accreditation, an enhanced DISCERN analysis and a number of readability indices. Of the 500 websites evaluated, 84 (16.8%) were HONcode‐accredited. Mean DISCERN scores of all websites were 74.9% and 38.6% for website reliability and treatment sections, respectively, demonstrating key gaps in comprehensiveness and reliability of GPP‐specific OHI. Additionally, only 4/100 websites (4%) analysed for readability were written at the NIH‐recommended sixth‐grade level. Academic websites were significantly more difficult to read than governmental websites. This further exacerbates the patient information gap, particularly for patients with low health literacy, who may already be at higher risk of not receiving timely medical care.
