An evaluation of the suitability, readability, quality, and usefulness of online resources for patients with cancer receiving immunotherapy.

Objective: To evaluate the suitability, readability, quality, and usefulness of available online resources about the side effects of immunotherapy.

Methods: Resources were identified through online searches (Google, Microsoft Bing, and Yahoo search engines) and evaluated using the Suitability Assessment Materials (SAM), three readability formulae, the DISCERN tool (quality), and a checklist of symptom management strategies and self-management skills (usefulness). Hierarchical cluster analysis identified resources scoring highly for suitability and quality.
