Intravenous Pump Flow Accuracy: A Systematic Review

Intravenous pumps (IVPs) deliver IV medications to millions of acute care patients each year and result in many adverse events reported to the US Food and Drug Administration (FDA). Although the use of IVPs has improved overall safety, there are still high rates of error that risk the safety of all patients, especially those of advanced age and those suffering from critical illness. Most of the documented errors are based on clinician reports, although there is reason to believe that errors due to flow rate inaccuracy go undetected and unreported. The purpose of this systematic literature review was to explore literature regarding flow rate accuracy for IVPs used in US acute care medicine. The systematic review was conducted by searching PubMed, CINHAL, and Web of Science. Articles chosen were from any year, written in the English language, and had content pertaining to the use of IVPs and key concepts of interest. Concepts discussed throughout the literature are relevant to the IVPs used for patient care, including outlet pressure, intake pressure, dead volume, and pump setup. This review provides a conceptual overview of what is known about this technology but reveals a gap in knowledge related to actual IVP clinical accuracy.
