An IPC committee has established an interdisciplinary CAUTI performance improvement team to identify potential root causes. Which quality assurance and performance improvement (QAPI) tool is used for this purpose?

• A. Ishikawa (fishbone) diagrams
• B. Failure Modes and Effects Analysis
• C. Flowchart
• D. Pareto charts

Answer: (A)

When a CAUTI problem is being explored, teams benefit from a visual tool that gathers and links possible causes across related areas. The fishbone diagram (Ishikawa) serves this purpose best because it lays out broad categories—such as people, processes, equipment, environment, materials, and policies—and invites the team to brainstorm specific factors under each. This creates a structured map of potential root causes, clarifying how different factors may contribute to CAUTI and guiding targeted improvements.

Other tools have different uses. A flowchart maps the steps in a process to spot where things might go wrong in sequence. A failure modes and effects analysis looks forward to identify possible failure points, assess their severity and likelihood, and prioritize mitigation. A Pareto chart helps focus on the most frequent problems after data are collected. While useful in their own right, they aren’t as directly suited for generating and organizing a comprehensive set of root causes across categories as a fishbone diagram.
