Illiteracy: The Silent Barrier to Health Care

Ann Intern Med. 1999;130(4_Part_1):333-336. doi:10.7326/0003-4819-130-4-199902161-00001

Workers in the field of health communication are sounding a warning on patients' reading skills. Emerging literature on illiteracy and health care indicates that up to 50% of certain clinical populations may be unable to read and understand medical instructions. As health care moves from the hospital to the home, researchers and clinicians are becoming increasingly aware of the challenges presented by the large number of illiterate patients. Mistakes resulting from poor reading skills can lead to repeated hospitalizations and may be costing the health care industry billions of dollars. In response, a group of public health researchers propose that physicians use pictographs when instructing patients; others suggest devoting extra attention to some patients with substandard reading skills and multiple medical problems.
