Posthospital medication discrepancies: prevalence and contributing factors.

Coleman EA, Smith JD, Raha D, et al. Archives of internal medicine. 2005;165:1842-7.

This study suggests that nearly 15% of patients discharged after hospitalization experience a medication discrepancy. Using data from 375 adults, investigators also discovered that the contributing factors to these discrepancies were split among patient- and system-related issues. The five most common medication classes implicated were anticoagulants, diuretics, angiotensin-converting enzyme inhibitors, lipid-lowering agents, and proton pump inhibitors. The authors conclude that use of a medication discrepancy tool can identify problems leading to medical errors, poor quality of care for chronic conditions, and unsafe transitions across care settings.
