In Preventable Medical Errors, medical expert witness Perry Hookman, M.D., writes that cancer outpatient medication errors may be more common than previously thought.
Adverse Drug Events [ADEs]
In a study by Hernández and Vargas (Adverse Drug Events in Ambulatory Care. NEJM.2003;349:303-305), of four primary care practices, the authors found that one-quarter of outpatients had adverse drug events during a three-month period. Of these events, 13% were serious, 39% were either ameliorable or preventable, and 6% were serious and preventable or ameliorable. Ameliorable adverse drug events were attributed to poor communication: the physician’s failure to respond to symptoms reported by the patient or the patient’s failure to report symptoms to the physician.
