VA-BC Quality Improvement 5 — Questions and Answers
Question 1: A vascular access team uses peer observation during PICC insertions. This practice is BEST categorized as which type of quality activity?
- Quality assurance (retrospective monitoring)
- Performance improvement (prospective real-time feedback) (Correct answer)
- Root cause analysis
- Regulatory compliance auditing
Correct answer: Performance improvement (prospective real-time feedback)
Peer observation during procedures provides real-time, prospective feedback to improve technique and compliance with insertion bundles.
Question 2: A hospital tracks catheter-days as a denominator in CLABSI rate calculations. Why is this metric preferred over number of patients?
- It is easier to calculate than patient counts
- It accounts for the duration of exposure and risk associated with catheter presence (Correct answer)
- It is required by state law for all hospitals
- It eliminates the need to track insertion dates
Correct 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.
Question 3: Which action BEST reflects application of Lean methodology in a vascular access QI initiative?
- Adding more steps to the insertion checklist for thoroughness
- Eliminating non-value-added steps in the central line request and placement workflow (Correct answer)
- Increasing the number of QI committee meetings per month
- Requiring dual nurse verification for every dressing change
Correct 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.
Question 4: 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?
- A visual trend on a run chart showing sustained shift below median
- Comparing the two rates using a chi-square or statistical process control analysis (Correct answer)
- Reporting the difference verbally at a staff meeting
- Repeating the measurement at a different hospital
Correct 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.
Question 5: 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?
- Continue using the connector and wait for more data over the next year
- Convene a rapid review, suspend the new connector, and investigate the association (Correct answer)
- Blame the nursing staff for improper scrub technique
- Report the issue only to the charge nurse without documentation
Correct 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.
Question 6: Which of the following is a STRUCTURAL measure in vascular access quality improvement?
- CLABSI rate per 1,000 catheter-days
- Percentage of nurses trained in central line insertion and care (Correct answer)
- Number of CLABSI events in a quarter
- Average time to catheter removal after order placed
Correct 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.
Question 7: 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?
- Expert opinion from a senior nurse
- Systematic review or meta-analysis of randomized controlled trials (Correct answer)
- A single case report from another institution
- Manufacturer's product literature
Correct 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.
