Define a root cause analysis (RCA) and list three methods/tools commonly used in healthcare safety investigations.

• A. RCA is a method for listing corrective actions without identifying root causes.
• B. RCA focuses on enforcing compliance metrics rather than investigating incidents.
• C. RCA identifies underlying causes of an incident; tools include Five Whys, fishbone (Ishikawa) diagram, and fault tree analysis.
• D. RCA only applies to mechanical failures and not to clinical processes.

Answer: (C)

Root cause analysis is a structured process used to uncover the underlying factors that contribute to an incident, so that you can address systemic issues and prevent recurrence rather than just treating the immediate event. In healthcare safety investigations, the goal is to dig into processes, workflows, human factors, equipment, policies, and communication gaps to find where the system allowed the incident to occur. Common methods used in RCA include the Five Whys technique, which involves repeatedly asking why to drill down to fundamental causes; the fishbone (Ishikawa) diagram, which organizes potential causes into categories such as people, processes, equipment, environment, and information to visualize relationships; and fault tree analysis, a deductive diagrammatic method that maps how various contributing events combine to produce the incident. These options are the best fit because they directly identify underlying causes and provide practical tools to analyze complex healthcare safety problems. Other descriptions fall short because RCA is not about listing corrective actions in isolation, nor is it about enforcing compliance metrics without investigation, and it certainly applies to clinical processes—not just mechanical failures.
