Seven percent of adults and 19 percent of children taking chemotherapy drugs in outpatient clinics or at home were given the wrong dose or experienced other mistakes involving their medications, according to a new study led by Kathleen E. Walsh, MD, assistant professor of pediatrics at the University of Massachusetts Medical School, and published in the January 1, 2009 issue of the Journal of Clinical Oncology.

Medication errors appear to be common, often hidden and associated with adverse events among patients receiving outpatient care after an organ transplant, according to a report in the March issue of Archives of Surgery, one of the JAMA/Archives journals. The health care system is involved with nearly one-third of these errors.
