The purpose of this research was to compare the design of Dose Error Reduction Software (DERS) between smart pumps to determine which features affect the ability of nurses to safely and efficiently program intravenous medications. A high-fidelity usability experiment was conducted. Twenty-four Registered Nurses completed a series of infusion tasks, in a simulated clinical environment, using three smart pumps (Cardinal Alaris System, BBraun Infusomat, and Hospira Symbiq). Results found significant differences in nursing performance across the smart pumps. Nurses were more likely to override clinically inappropriate soft limit alerts when using BBraun Infusomat, than when using Hospira Symbiq or Cardinal Alaris System. Furthermore, when asked to program an infusion over a specific duration, nurses were found to make significantly more parameter entry errors when using Hospira Symbiq than when using Cardinal Alaris System. Results from this study will help set DERS design principles, and assist hospitals during their procurement processes.
