Objectives: The purpose of this study was to analyze the quality, accuracy, and readability of patient information on PCOS available online in English. We hypothesized that there would be a difference in the quality of the PCOS information as assessed by the DISCERN tool according to search engine and producer. As well as a difference in the clarity of the PCOS information as assessed by the EQIP tool according to search engine and producer. We further hypothesized that there would be a difference in accuracy of the information on PCOS symptoms between the different search engines and producer type. Lastly, we hypothesized that there would be a different median readability level of the PCOS information according to both search engine and producer type. Materials and methods: We imitated search strategies of the general public. Using a systematic methodology, we examined the quality, clarity, accuracy, and readability of online information about PCOS available in English. Internet searches were performed with five separate searches using the keywords from Google Trends. The searches were preformed using Google, Bing and Yahoo search engines extracting the top 10 webpages from each. A total of 150 unique webpages were evaluated and categorized. Results: The majority of webpages were commercial (n=85, 57%), compared to non-commercial which were the remaining (n=65, 43%). Google webpages describing PCOS had a significant higher median DISCERN score than webpages from Bing and Yahoo. The overall DISCERN score was higher for non-commercial webpages than for commercial, but no scientific significant difference was established. The quality of information showed 39 (26%) webpages rated as good or excellent, 58 (39%) webpages rated as fair and 53 (35%) rated as poor or very poor. According to the EQIP score there was no significant difference between the scores according to Google, Bing or Yahoo. According to webpage producer, non-commercial webpages had a slightly higher score than commercial, with no significant difference being established. An overall high score was achieved by (24%) of the webpages and the remaining (76%) achieved a low score. We found no significant difference in the comparison of the specific accuracy ratings by either producer or search engine. Comparisons in the readability did not reach statistical significance between the three search engines nor between the commercial and non-commercial webpages. Conclusion: High-quality information regarding PCOS with the recommended reading level is lacking. Out of the three search monitors Google showed the best quality. Online information regarding PCOS in English had a high symptom accuracy level. Clarity, accuracy and reading level did not show significant differences between search monitors and producers.
