Health Literacy Lacking in the US

April 9, 2004 -- Close to half of all adults in the US do not understand health information, according to a report issued by the Institute of Medicine. This lack of medical literacy compromises their ability to care for themselves and their families.

Quote: "Health literacy is fundamental to quality care." (Dr. David A. Kindig, chair of the Committee on Health Literacy, the Institute of Medicine)

Comment: The lack of medical literacy is not a new problem but it is a very serious one that can impair health and even be life-threatening.

90 Million Americans are Burdened with Inadequate Health Literacy IOM Report Calls for National Effort to Improve Health Literacy

WASHINGTON -- Nearly half of all American adults - 90 million people - have difficulty understanding and using health information, and there is a higher rate of hospitalization and use of emergency services among patients with limited health literacy, says a new report from the Institute of Medicine of the National Academies. Limited health literacy may lead to billions of dollars in avoidable health care costs.

More than a measurement of reading skills, health literacy also includes writing, listening, speaking, arithmetic, and conceptual knowledge. Health literacy is defined as the degree to which individuals have the capacity to obtain, process, and understand basic information and services needed to make appropriate decisions regarding their health.

"Health literacy is fundamental to quality care," said committee chair David A. Kindig, professor emeritus of population health sciences, University of Wisconsin, Madison. "The public's ability to understand and make informed decisions about their health is a frequently ignored problem that can have a profound impact on individuals' health and the health care system. Most professionals and policy-makers have little understanding of the extent and effects of this problem."

A concerted effort by the public health and health care systems, the education system, the media, and health care consumers is needed to improve the nation's health literacy, the report says. If patients cannot comprehend needed health information, attempts to improve the quality of care and reduce health care costs and disparities may fail.

Limited health literacy affects more than just the uneducated and poor, the report says. At some point, most individuals will encounter health information they cannot understand. Even well educated people with strong reading and writing skills may have trouble comprehending a medical form or doctor's instructions regarding a drug or procedure.

Health literacy skills are needed for discussing care with health professionals; reading and understanding patient information sheets, consent forms, and advertising; and using medical tools such as a thermometer. Over 300 studies indicate that health-related materials cannot be understood by most of the people for whom they are intended.

Individuals are increasingly responsible for managing their own health care, the committee noted. They are assuming new roles in seeking information, measuring and monitoring their own health, and making decisions about insurance and options for care. Patients' health often depends on their ability and willingness to carry out a set of activities needed to manage and treat their disease. This self-management is essential to successful care of chronic diseases such as diabetes, HIV, and hypertension. Patients with chronic illness who have limited health literacy are less knowledgeable about disease management and less likely to use preventive measures.

Limited health literacy is not a problem that starts and ends with patients, the committee added. Health systems are becoming increasingly complex, involving new technologies, scientific jargon, and complicated medical procedures and forms. All of these aspects of the health system can be confusing to patients. Moreover, care providers frequently need to communicate with patients who have different language and cultural backgrounds. Culture and ethnicity may influence patients' perceptions of health, illness, and the risks and benefits of treatments. Differing cultural and educational backgrounds between a patient and provider also contribute to problems in the patient's comprehension.
