Root cause analysis in infusion nursing: applying quality improvement tools for adverse events.

The success of this valuable quality improvement tool relies on understanding the principles of patient safety, assembling a team, and producing and completing action items aimed at correcting root causes of adverse events. This article describes optimal RCA techniques based on published literature and expert opinion and then provides a sample RCA for a fictitious but common adverse event: catheter-associated bloodstream infection.
