Critical Quality and Readability Analysis of Online Patient Education Materials on Parotidectomy: A Cross-Sectional Study

Purpose: Complications related to parotidectomy can cause significant morbidity, and thus, the decision to pursue this surgery needs to be well-informed. Given that information available online plays a critical role in patient education, this study aimed to evaluate the readability and quality of online patient education materials (PEMs) regarding parotidectomy. Methods: A Google search was performed using the term “parotidectomy” and the first 10 pages of the search were analyzed. Quality and reliability of the online information was assessed using the DISCERN instrument. Flesch-Kincaid Grade Level (FKGL) and Flesch-Reading Ease Score (FRE) were used to evaluate readability. Results: Thirty-five PEMs met the inclusion criteria. The average FRE score was 59.3 and 16 (46%) of the online PEMs had FRE scores below 60 indicating that they were fairly difficult to very difficult to read. The average grade level of the PEMs was above the eighth grade when evaluated with the FKGL. The average DISCERN score was 41.7, which is indicative of fair quality. There were no significant differences between PEMs originating from medical institutions and PEMs originating from other sources in terms of quality or readability. Conclusion: Online PEMs on parotidectomy may not be comprehensible to the average individual. This study highlights the need for the development of more appropriate PEMs to inform patients about parotidectomy.
