Adoption of smart infusion pump technology was intended to improve medication safety, but past reports describe the ability of nurses to create work-arounds. This study examined preventable intravenous adverse drug events (IV-ADEs) and discovered that only 4% could be intercepted by a smart pump. Investigators reviewed medical records, both before and after adoption of smart pumps, to draw these conclusions. They also provide a qualitative analysis of errors causing preventable IV-ADEs and propose solutions that would improve smart pump technology.
