Accepted Answer

To compare performance against a standard and identify improvement opportunities

Answer

Benchmarking compares an organization's performance to external standards to identify gaps and drive targeted improvement.

Question 4

Which data display method is BEST for tracking CLABSI rates over 12 months to identify trends?

Accepted Answer

Run chart

Answer

A run chart plots data points over time and is ideal for detecting trends, shifts, or patterns in a process.

Question 5

A QI team wants to prioritize which central line complications to address first. Which tool ranks issues by frequency to identify the 'vital few'?
