Health literacy (HL) has been linked to health outcomes in a variety of settings. Patients and families with a high degree of health literacy are more likely to be adherent to medical care plans, whereas those with a low health literacy have higher emergency department (ED) visits, postsurgical complications, and less likelihood of a desired health outcome. There is convincing evidence that limited HL is more prevalent in specific risk groups (such as low education groups) and is associated with poorer health/social outcomes and specific patterns of healthcare service use (DeWalt DA, Hink A, Pediatrics 124:S265–S274, 2009). Data has also shown increased healthcare costs due to poor HL.
