Quality Improvement Flashcards

A vascular access team uses peer observation during PICC insertions. This practice is BEST categorized as which type of quality activity?

Answer: Performance improvement (prospective real-time feedback)

Peer observation during procedures provides real-time, prospective feedback to improve technique and compliance with insertion bundles.

A hospital tracks catheter-days as a denominator in CLABSI rate calculations. Why is this metric preferred over number of patients?

Answer: It accounts for the duration of exposure and risk associated with catheter presence

Using catheter-days as the denominator accounts for the actual time each patient is exposed to infection risk from a catheter.

Which action BEST reflects application of Lean methodology in a vascular access QI initiative?

Answer: Eliminating non-value-added steps in the central line request and placement workflow

Lean focuses on identifying and eliminating waste (non-value-added steps) to streamline processes and improve efficiency and quality.

A QI initiative successfully reduces CLABSI rates from 2.1 to 0.7 per 1,000 catheter-days. Which statistical test would BEST confirm this is a significant improvement and not random variation?

Answer: Comparing the two rates using a chi-square or statistical process control analysis

Statistical analysis such as chi-square testing or SPC methods determines whether the improvement exceeds what would be expected by chance.

A nurse notes that a new needleless connector type introduced during a CLABSI bundle update correlates with an increase in infections. What is the APPROPRIATE QI response?

Answer: Convene a rapid review, suspend the new connector, and investigate the association

A rapid review and temporary suspension of the suspected product follows patient safety and QI principles when a new intervention may be causing harm.

Which of the following is a STRUCTURAL measure in vascular access quality improvement?

Answer: Percentage of nurses trained in central line insertion and care

Structural measures assess the capacity and resources in place — such as staff training — that enable safe care delivery.

A vascular access nurse serves on the hospital QI committee and is asked to present on infection prevention. Which evidence level MOST strongly supports a practice recommendation?

Answer: Systematic review or meta-analysis of randomized controlled trials

Systematic reviews and meta-analyses of RCTs represent the highest level of evidence in evidence-based practice hierarchies.
