What is medication reconciliation and why is it important during transitions of care?

• A. Process of comparing a patient’s medication lists to ensure accuracy and prevent omissions, duplications, or interactions during handoffs.
• B. Process of simplifying medication lists by removing all refills.
• C. Verifying allergy lists only.
• D. Recording medication costs.

Answer: (A)

Medication reconciliation is the deliberate process of creating the most accurate list of a patient’s medications and then comparing that list with the orders at hand to identify and fix discrepancies as they move between care settings. This means gathering every medication the patient is actually taking (drug name, dose, route, frequency, and purpose), comparing it to what is being prescribed or ordered, and resolving any omissions, duplications, incorrect doses, or potential drug interactions.

Why this matters during transitions of care is that critical information often gets lost or altered when a patient moves from one setting to another—such as from hospital to home or between departments within a hospital. If a medication is accidentally omitted, duplicated, or changed without proper verification, it can lead to adverse drug events, ineffective treatment, and even hospital readmissions. Reconciliation helps ensure continuity of therapy, safety, and clear communication to the next care team.

The process usually involves: collecting an up-to-date medication history from the patient, family, and previous records; comparing that history with current orders; resolving discrepancies in collaboration with the patient and healthcare providers; documenting the reconciled list; and communicating it to the next care setting. This approach emphasizes accuracy and safety across transitions, rather than simply trimming lists, focusing only on allergies, or tracking costs.
