Medication reconciliation in the emergency department performed by pharmacists.

Patients are at risk of having their medication histories inaccurately documented while being admitted to an emergency department (ED). Allowing a pharmacist to access patient medication history is an effective way of reducing the number of errors. We sought to determine if having a pharmacist (as opposed to the admitting clinical team) verify patients' medication histories would result in fewer discrepancies in inpatient medication regimens.
