A multidisciplinary team developed a new process for the pharmacist to obtain an extensive medication history on hospital admission, and then reconcile medication histories using a discharge medication reconciliation report generated by a electronic medical record medication documentation tool. Pharmacists received intensive training and hospitalwide multidisciplinary education was provided. The authors conclude that a pharmacy-driven multidisciplinary admission history and medication reconciliation process reduced medication errors from 90 percent to 47 percent on the surgical unit, and from 57 percent to 33 percent on the medicine unit.
