None of the 15 websites studied, therefore, demonstrated optimal features on combined measures of accountability, quality, readability, display, support, and transparency regarding HQ. Notably, the American Academy of Dermatology website (www.aad.org) was not among the 15 websites studied; the AAD website mentions HQ in a section on melasma, but only minimal detail is provided.
Limitations of this study include the small number of websites analyzed and possible selection bias because only 3 internet search engines were used to identify websites for study and analysis.
Previously, we analyzed content about HQ on the video-sharing and social media platform YouTube.4 The most viewed YouTube videos on HQ had poor-quality information (ie, only 20% mentioned ochronosis and only 28.6% recommended sunscreen [N=70]). However, average reading level of these videos was 7th grade.4,5 Therefore, YouTube HQ content, though comprehensible, generally is of poor quality.
By conducting a search for website content about HQ, we found that the most popular URLs had either accurate information with poor readability or lower-quality educational material that was more comprehensible. We conclude that there is a need to develop online patient education materials on HQ that are characterized by high-quality, up-to-date medical information; have been written by board-certified dermatologists; are comprehensible (ie, no more than approximately 1200 words and written at a 7th-grade reading level); and contain relevant clinical images and references. We encourage dermatologists to recognize the limitations of online patient education resources on HQ and educate patients on the proper use of the drug as well as its potential adverse effects
