A medication management concept defining processes used to prepare, administer, and monitor therapies safely. It governs verification steps, timing, dose accuracy, monitoring for adverse effects, and documentation of administration events. It does not prevent harm without adherence to verification and monitoring steps and escalation when risks are detected. It materially affects outcomes by improving therapeutic effectiveness and reducing medication-related errors. The concept is generally stable, though safety practices and monitoring expectations evolve over time.

Principle

Explicit verification, clarification and documentation at each transition of care (admission, transfer, discharge) prevents omission, duplication, dosing errors and harmful interactions; it requires patient or caregiver engagement and reliable information sources (patient report, community pharmacy, prior records).

Demonstration

At hospital admission a pharmacist interviews the patient and reconciles their home medication list against admission medication orders, identifying an omitted anticoagulant that is reinstated with an adjusted plan and documented rationale; reconciliation is repeated at discharge with clear patient instructions and communication to the primary care provider and community pharmacy.

Misapplication

Performing a superficial checklist without verification from the patient or external sources, reconciling only prescription drugs while ignoring OTC and herbal products, or documenting changes without communicating them to receiving clinicians and the patient.

Consequence

Accurate medication reconciliation reduces medication discrepancies, prevents adverse drug events at transitions, improves continuity of therapy, and supports safer prescribing and patient understanding of their regimen.

Reversal

Failing to reconcile medications or assuming lists are correct transfers risk to the next care setting; this inversion increases preventable medication errors and patient harm during transitions.

Boundary

Pertains to the accuracy and continuity of medication lists across transitions; it is distinct from medication review (which evaluates appropriateness, interactions and deprescribing) though both should be linked in practice.

Semantic Tension

Reconciliation versus review: reconciliation focuses on accurate transfer of what the patient actually takes, while review interrogates whether each medicine should be continued; conflating them obscures responsibility and timing of actions.

Synthesis

Medication reconciliation is a repeatable, documented verification and resolution process at care transitions that ensures an accurate medication list, enabling safe prescribing and continuity of therapy.
