University of North Carolina School of Nursing & Institute of Medicine of the National Academies: Medication Study
Medication errors are among the most common medical errors, harming at least 1.5 million people every year, says a new report from the Institute of Medicine of the National Academies. The extra medical costs of treating drug-related injuries occurring in hospitals alone conservatively amount to $3.5 billion a year, and this estimate does not take into account lost wages and productivity or additional health care costs, the report says. The committee that wrote the report recommended a series of actions for patients, health care organizations, government agencies, and pharmaceutical companies. The recommendations include steps to increase communication and improve interactions between health care professionals and patients, as well as steps patients should take to protect themselves. The report also recommends the creation of new, consumer-friendly information resources through which patients can obtain objective, easy-to-understand drug information. In addition, it calls for all prescriptions to be written electronically by 2010 and suggests ways to improve the naming, labeling, and packaging of drugs to reduce confusion and prevent errors. "The frequency of medication errors and preventable adverse drug events is cause for serious concern," said committee co-chair Linda R. Cronenwett, dean and professor, School of Nursing, University of North Carolina, Chapel Hill. "We need a comprehensive approach to reducing these errors that involves not just health care organizations and federal agencies, but the industry and consumers as well," she said.
Medication errors encompass all mistakes involving prescription drugs, over-the-counter products, vitamins, minerals, or herbal supplements. Errors are common at every stage, from prescription and administration of a drug to monitoring of the patient's response, the committee found. It estimated that on average, there is at least one medication error per hospital patient per day, although error rates vary widely across facilities. Not all errors lead to injury or death, but the number of preventable injuries that do occur -- the committee estimated at least 1.5 million each year -- is sobering, the report says. Studies indicate that 400,000 preventable drug-related injuries occur each year in hospitals. Another 800,000 occur in long-term care settings, and roughly 530,000 occur just among Medicare recipients in outpatient clinics. The committee noted that these are likely underestimates. There is insufficient data to determine accurately all the costs associated with medication errors. The conservative estimate of 400,000 preventable drug-related injuries in hospitals will result in at least $3.5 billion in extra medical costs this year, the committee calculated. A study of outpatient clinics found that medication-related injuries there resulted in roughly $887 million in extra medical costs in 2000 -- and the study looked only at injuries experienced by Medicare recipients, a subset of clinic visitors. None of these figures take into account lost wages and productivity or other costs. Establishing and maintaining strong partnerships between health care providers and patients is crucial to reducing medication errors, the report says. The committee called on consumers to be active partners in their medication care and on physicians, nurses, and pharmacists to know and act on patients' medical care rights.
The report recommends specific steps that physicians, nurses, pharmacists, and other health professionals should take to ensure that their patients are fully informed about their drug regimens and to minimize opportunities for mistakes to occur. Health care organizations also should make it a standard procedure to inform patients about clinically significant medication errors made in their care, whether the mistakes lead to harm or not. Currently, health care providers typically do not inform the patient or the patient's guardians about errors unless injury or death results. The report also provides consumers with a list of specific questions to ask health care providers, such as how to take their medications properly and what to do if side effects occur. Also included are actions consumers should take, such as requesting that their providers give them a printed record of the drugs they have been prescribed. Patients should maintain an up-to-date list of all medications they use -- including over-the-counter products and dietary supplements -- and share it with all their health care providers. This list should also note the reasons they are taking each product and any drug and food allergies they have. Although consumers can find helpful drug information online or in the printed materials provided by pharmacies, this information often is too difficult for many people to understand, too scattered, or otherwise not consumer-friendly. The quality of the drug information leaflets that accompany prescriptions varies widely, and these printouts are typically written at a college reading level. The U.S. Food and Drug Administration (FDA) should work with other appropriate groups to standardize the text and design of medication leaflets to ensure that they are comprehensible and useful to all consumers.
