BACKGROUND: Patients are increasingly using the internet to access health-related information. The purpose of this study was to assess the readability and quality of laryngeal cancer-related websites. METHODS: Patient education materials were identified by performing an internet search using 3 search engines. Readability was assessed using Flesch Reading Ease Score (FRES), Flesch-Kincaid Grade Level (FKGL), and Gunning Fog Index (GFI). The DISCERN instrument was utilized to assess quality of health information. RESULTS: A total of 54 websites were included in the analysis. The mean readability scores were as follows: FRES, 48.2 (95% confidence interval CI = 44.8-51.6); FKGL, 10.9 (95% CI = 10.3-11.5); and GFI, 13.8 (95% CI = 11.3-16.3). These scores suggest that, on average, online information about patients with laryngeal cancer is written at an advanced level. The mean DISCERN score was 49.8 (95% CI = 45.4-54.2), suggesting that online information is of variable quality. CONCLUSION: Our study suggests much of the laryngeal cancer information available online is of suboptimal quality and written at a level too difficult for the average adult to read comfortably.
