Which of the following quality improvement tools can best demonstrate length-of-stay data?

In the Performance and Process Improvement domain, NAHQ emphasizes selecting tools that match the type of data and purpose of analysis. Length of stay is a continuous measure that is best analyzed over time.

A run chart displays data points in chronological order and helps identify trends, shifts, or cycles in performance. This makes it ideal for monitoring length-of-stay changes following interventions.

Pareto charts (Option B) prioritize categories, flowcharts (Option C) map processes, and Gantt charts (Option D) track project timelines. None of these tools are designed to show performance trends over time. Therefore, Option A is the correct choice.
