A 1999 Institute of Medicine report received national attention by highlighting system vulnerabilities within health care and indicating that medication errors are a leading cause of morbidity and mortality. One area of concern was the increased number of errors occurring in the prescribing phase of the medication-use process due to prescribers’ lack of essential drug knowledge and patient information at the time of ordering. Pharmacists’ participation in medical rounds has demonstrated a reduction in medication errors in the ordering stage. However, at most hospitals, pharmacists are not directly involved in obtaining medication histories, despite the findings of one study showing that over 70% of drug-related problems were recognized only through a patient interview and another study reporting a 51% reduction in medication errors when pharmacists were involved in obtaining medication histories. Medication errors and patient harm can result from inaccurate or incomplete histories that are subsequently used to generate medication KRISTINE M.
