Frail older adults tend to have multiple medical, cognitive, and functional problems. They are at increased risk of using health care services and may undergo multiple transitions from service to service. It is not difficult for patients and health care providers to articulate the consequences of poor health care transitions, which may include confusion in action plans (diagnoses, medications, care needs), potential errors during handoffs, avoidable delays and/or frustrations, adverse medical events, readmissions to the most recently used service, stress for health care staff, and, ultimately, mortality.1 One of the quality indicators of effective health care transitions is error reduction, and a common strategy to achieve this indicator involves medication reconciliation. The latter refers to “a formal process of obtaining a complete and accurate list of each patient’s current home medicationsdincluding name, dosage, frequency and routedand comparing the physician’s admission, transfer, and/or discharge orders to that list. Discrepancies are brought to the attention of the prescriber and, if appropriate, changes are made to the orders. Any resulting changes in orders are documented.”2 Medication discrepancies are associated with undesirable outcomes,3 and when these occur during points of health care transitions, they can be difficult to overcome. For instance, one Australian randomized controlled trial showed that the addition of a pharmacist transition coordinator when transferring from hospital to residential care could significantly improve a patient’s pain control while reducing hospitalization, but did not reduce adverse drug events, falls, immobility, worsening behaviors, or cognitive impairment.4 In this issue of the Journal, Sinvani et al5 report on an important study that looks at medication reconciliation as measured by discrepancies in subacute older patients at 3 points of care transition: hospital admission to discharge (time I), hospital discharge to skilled nursing facility (time II), and skilled nursing facility admission to discharge home or long term care (time III). The study question is clinically relevant, especially given the recent emphasis on quality improvement and patient safety.
