A healthcare quality professional has identified sepsis as a high-volume, high-cost patient condition.

Step-by-Step Explanation:1. Objective:Evaluate whether the sepsis care bundle improved patient outcomes by reducing Length of Stay (LOS).

2. Compare Averages:Month

Previous Year: (3+5+8+12+9+14+8+8+12+6+8+9) / 12 = 8.5 days

Current Year: (2+6+6+5+8+4+8+8+9+6+10+6) / 12 = 6.75 days

Average LOS:➡️ Result: LOS decreased by 1.75 days on average

A control chart is used to track variation over time and identify special cause vs. common cause variation.

This project evaluates process stability and performance before and after an intervention (sepsis care bundle).

It helps answer: Is the reduction statistically significant or just random?

Why a Control Chart?

A. Incorrect: LOS decreased, not increased; bar graphs don’t show variation over time.

B. Incorrect: While LOS decreased, Pareto charts are for identifying priorities based on frequency—not trend over time.

D. Incorrect: LOS did not increase; run charts show trends but lack the statistical power of control charts to detect special cause variation.

Why the other options are incorrect:
