AMIA 2012: Applying Human Factors Principles to Improve Medication Alerts

ABSTRACT: The effectiveness of electronic medications alerts can be influenced by the design of the user interface, but few empiric studies have evaluated the alert interface. We applied human factors principles to redesign alerts (i.e. order checks) from the VA’s computerized provider order entry (CPOE) system. Simulation experiments were conducted with 20 prescribers to evaluate whether design changes improved alert usability. Prescribers rated several aspects of usability significantly higher for redesigned alerts, including ‘information quality’ and ‘interface quality’. This is one of the first studies to rigorously evaluate specific features of alert interface design. Findings may be used to improve the design of alerts, which may subsequently improve alert usability and patient safety.
