The Need for Medication Reconciliation Increases with Age.

Background: Medication reconciliation (MR) at hospital admission, transfer, and discharge has been designated as a required hospital practice to reduce adverse drug events.

Objectives: To perform MR among elderly patients admitted to the hospital and to determine factors that influence differences between the various lists of prescribed drugs as well as their actual consumption.

Methods: We studied patients aged 65 years and older who had been admitted to the hospital and were taking at least one prescription drug.
