The role of "smart" infusion pumps in patient safety.

"Smart" infusion pumps are medication delivery devices that use a combination of computer technology and drug libraries to limit the potential for dosing errors. The evidence for their impact is limited: they have been shown to prevent some errors but there are minimal data linking the devices to reducing harm. Reasons for the limited impact include poor design leading to usability issues including programming errors, varying degrees of end-user acceptance, and their contingent nature. Iterative user-centered design, coupled with network and real-time monitoring of alerts may enhance the impact of these devices.
