Medication Reconciliation Best Practices: Reducing Errors at Transitions of Care

Why Medication Reconciliation Matters

Medication reconciliation is the process of creating the most accurate list of medications a patient is taking and comparing that list against the physician's orders at every transition of care. Transitions include admission, transfer between units, and discharge. Research has consistently shown that medication discrepancies at transitions contribute to adverse drug events, hospital readmissions, and patient harm. The Joint Commission includes medication reconciliation as a National Patient Safety Goal, making it a core competency for quality professionals and a common topic on the CPHQ exam.

Key Steps in the Reconciliation Process

Effective medication reconciliation follows a structured process. First, a comprehensive medication history is obtained from multiple sources, including the patient interview, pharmacy records, primary care provider records, and any available health information exchange data. Second, the medication list is verified for accuracy, including drug names, doses, frequencies, and routes. Third, the verified list is compared against current orders to identify and resolve discrepancies. Fourth, the reconciled list is communicated to the patient and the next provider of care. Each step requires careful attention to detail and clear documentation in the medical record.

Common Barriers and Solutions

Several barriers can undermine medication reconciliation effectiveness. Patients may not accurately recall their medications, particularly if they take multiple drugs or use over-the-counter supplements. Multiple medication lists in the EHR can create confusion about which list is current. Time pressures during busy admissions and discharges may lead to rushed or incomplete reconciliation. Solutions include using pharmacy technicians or trained medication history specialists to conduct detailed interviews, implementing EHR-based reconciliation tools, and standardizing the reconciliation workflow to ensure consistency across providers and settings.

Quality Measures for Medication Reconciliation

Quality measures related to medication reconciliation track whether the process is completed at specified transitions and whether discrepancies are identified and resolved. The National Quality Forum has endorsed measures that address post-discharge medication reconciliation, and CMS includes reconciliation measures in several quality reporting programs. Quality professionals monitor compliance rates, audit the accuracy and completeness of reconciled medication lists, and provide feedback to clinicians and pharmacists. Tracking the types and severity of discrepancies found during reconciliation helps quantify the safety value of the process.

Best Practices for Quality Professionals

Quality professionals can improve medication reconciliation outcomes by advocating for standardized processes, supporting EHR optimization, and promoting interprofessional collaboration. Engaging pharmacists as key participants in the reconciliation process improves accuracy and identifies clinically significant discrepancies. Patient engagement strategies, such as encouraging patients to maintain personal medication lists and using the teach-back method during discharge education, support accurate reconciliation. Regular auditing and feedback cycles help sustain compliance and drive continuous improvement in reconciliation quality.
