Poor Readability of Online Patient Resources Regarding Sentinel Lymph Node Biopsy for Melanoma

Background Established guidelines recommend that patient educational materials should be set at no higher than a sixth-grade reading level to be considered adequately comprehensible to the general public. Our study objective was to assess the readability of online patient resources related to sentinel lymph node biopsy (SLNB) as part of treatment for melanoma. Materials and methods The top 50 results from a Google search (search terms: "sentinel lymph node biopsy melanoma") were analyzed using seven established readability formulae in order to determine their level of adherence to current guidelines. Results We found that the readability of available online patient resources is currently very poor, with only 12% of the websites meeting the sixth-grade reading level criteria according to at least one measure, and 0% meeting the criteria according to all seven assessment tools. Furthermore, half of search results were peer-reviewed academic journal articles not intended for the general public. Discussion and conclusions Online patient resources related to SLNB carried out as part of melanoma treatment have poor readability. Several simple measures may be taken in order to make these resources more accessible and comprehensible to a broader audience. These resources should undergo ongoing evaluation, with the ultimate goal being improved readability and patient education.
