Medication review and medication reconciliation are systematic processes with the aim of increasing patient safety as well as effectiveness and efficiency on different levels. Whereas medication reconciliation is defined as the formal process of obtaining a complete and accurate list of each patient's current medications with the main aim of detecting and solving discrepancies, medication review is a structured evaluation of a patient's medications with the aim of detecting and solving drug-related problems (DRPs). The available information determines which DRPs can be detected. If a medication list/plan has to be critically appraised, then the list should first be complete and correct. This makes reconciliation automatically a prerequisite for a medication review.
