The National Coordinating Council for Medication Error Reporting and Prevention defines a medication error as "Any preventable event that may cause or lead to inappropriate medication use or patient harm while the medication is in the control of the health care professional, patient, or consumer. Such events may be related to professional practice, health care products, procedures and systems, including prescribing, order communication, product labeling, packaging and nomenclature, compounding, dispensing, distribution, administration, education, monitoring and use."
Recently there has been a good deal of publicity about whether or not middle aged women are getting too many false positives following routine mammograms. Most people probably know that a "false positive" is medical jargon for a false alarm or erroneous suggestion that there is something wrong medically, when in fact there is not. Because of this, a good many women who really had nothing wrong with their breasts wound up having biopsies, etc. because of the mammography report.
