An excellent "Health Literacy Toolkit" has been developed by the University of North Carolina at Chapel Hill for AHRQ, the Agency for Healthcare Research and Quality. The website for this self-assessment tool includes a 6 minute video and 20 informative sections or "tools" that address areas of concern. The information is relevant for both adult and pediatric patients.
The toolkit suggests that caregivers assume everyone has some difficulty in understanding health-related information. It gives tips on improving written and spoken communication. It recommends that patient families be encouraged to ask questions -- and understand the answers.
