Assisted living nursing practice: health literacy and chronic illness management.

Functional illiteracy is an inability to read sufficient to function in society. In the high-tech, information-dependent environment of postindustrial society, being illiterate is being at risk. Health literacy is the ability to access, understand, and use basic information about health conditions and services that is necessary to make informed decisions. Older adults (>/=65 years of age) have lower health literacy than all other age groups. Limited health literacy is associated with greater use of emergency department visits, increased rates of hospitalization, and failure to take important diagnostic tests. To maintain independence and self-determination, assisted living (AL) residents need to be able to understand a new or changed diagnosis, as well as oral and written instructions, especially with regard to their medication management. This article discusses health literacy, "plain language," and assessment and interventions to maintain health literacy.
