Quality Improvement Flashcards

A hospital implements daily catheter necessity reviews. Which outcome is this intervention MOST directly designed to prevent?

Answer: Unnecessary catheter dwell time and associated infection risk

Daily necessity reviews prompt timely removal of catheters no longer clinically indicated, directly reducing dwell time and infection risk.

When analyzing QI data, a control chart shows a data point beyond the upper control limit. This is BEST interpreted as:

Answer: A signal of special cause variation requiring investigation

A data point beyond control limits indicates special cause variation — an unusual event that warrants investigation and response.

A vascular access nurse is asked to create a process map of central line insertion. What is the PRIMARY benefit of this activity?

Answer: Identifying steps, decision points, and potential gaps in the insertion workflow

Process mapping visualizes each step in a workflow, revealing inefficiencies, redundant steps, or gaps where errors may occur.

Which QI framework focuses on defining defects, measuring current performance, analyzing causes, improving, and then controlling the process?

Answer: DMAIC

DMAIC (Define, Measure, Analyze, Improve, Control) is the Six Sigma framework used for structured process improvement.

A unit reduces CLABSI rates and wants to sustain results. Which strategy is MOST effective for long-term sustainment?

Answer: Embedding bundle compliance into routine auditing and performance dashboards

Sustained improvement requires ongoing monitoring through audits and visible performance data to maintain accountability and early detect regression.

A QI team discovers that PICC dressing changes are performed inconsistently across three nursing units. Which approach BEST reduces this variation?

Answer: Standardize the dressing change procedure across all units using a single evidence-based protocol

Standardizing procedures based on evidence reduces variation, which is a core Lean principle for improving consistency and outcomes.

When reporting QI outcomes to hospital leadership, which measure MOST effectively communicates the clinical and financial impact of reducing CLABSI?

Answer: CLABSI events prevented and estimated cost savings per infection avoided

Translating CLABSI reductions into prevented events and associated cost savings demonstrates the value of QI investment to leadership.
