Abstract
Health literacy is an important skill for people receiving care. Those with limited literacy face disparities in their care and health outcomes when strategies for addressing literacy are not used when delivering health information. In this article, we introduce the importance of considering health literacy, defining it and related concepts including numeracy, graph literacy, and digital literacy, and discuss open questions about measuring health literacy in clinical care. Finally, we present best practices, including assuming 'universal precautions', carefully considering wording, leveraging visualizations, recognizing cultural differences in interpretation, providing guidance on pilot testing, and considering digital literacy when developing electronic materials.
