CPHQ Performance and Process Improvement 3 — Questions and Answers
Question 1: A hospital's readmission rate is 18%, and the national benchmark is 12%. After implementing a discharge coaching program, the rate drops to 14%. This improvement is BEST described as:
- Meeting the benchmark
- Closing the performance gap (Correct answer)
- Eliminating special cause variation
- Achieving zero defects
Correct answer: Closing the performance gap
Closing the performance gap refers to reducing the difference between current performance and the benchmark, even if the benchmark has not yet been fully reached.
Question 2: Which component of the Institute for Healthcare Improvement (IHI) Model for Improvement asks teams to identify what change they will make?
- What are we trying to accomplish?
- How will we know a change is an improvement?
- What change can we make that will result in improvement? (Correct answer)
- When will we implement the change?
Correct answer: What change can we make that will result in improvement?
The IHI Model for Improvement's third fundamental question focuses on identifying specific changes that are likely to lead to improvement.
Question 3: In Lean methodology, a 'value stream map' is used to:
- Track individual employee performance metrics
- Visualize all steps in a process and identify non-value-added activities (Correct answer)
- Create financial projections for improvement projects
- Document regulatory compliance requirements
Correct answer: Visualize all steps in a process and identify non-value-added activities
A value stream map depicts every step in a process flow, distinguishing value-added from non-value-added (waste) activities to target improvement opportunities.
Question 4: A quality team discovers that a medication error reporting process has a defect rate of 3.4 per million opportunities. This performance level corresponds to:
- Three Sigma
- Four Sigma
- Five Sigma
- Six Sigma (Correct answer)
Correct answer: Six Sigma
Six Sigma performance is defined as 3.4 defects per million opportunities, representing near-perfect process capability.
Question 5: A fishbone (Ishikawa) diagram is PRIMARILY used to:
- Display trends in outcome data over time
- Identify and categorize potential causes of a problem (Correct answer)
- Prioritize improvement projects by impact and effort
- Track the completion of improvement action items
Correct answer: Identify and categorize potential causes of a problem
A fishbone diagram organizes potential causes of a problem into categories (e.g., people, process, equipment) to facilitate comprehensive root cause analysis.
Question 6: When conducting a rapid cycle improvement, a team should test changes on a small scale FIRST because:
- Regulators require small-scale testing before full implementation
- Small-scale tests minimize risk and allow learning before broader rollout (Correct answer)
- Small-scale changes are always more cost-effective
- Large-scale tests require board approval in all cases
Correct answer: Small-scale tests minimize risk and allow learning before broader rollout
Small-scale testing (as in PDSA cycles) reduces risk, enables learning from failures cheaply, and provides evidence before committing resources to full implementation.
Question 7: Which of the following is an example of a 'leading indicator' in a healthcare quality improvement initiative?
- 30-day readmission rate
- Annual patient mortality rate
- Hand hygiene compliance rate during rounds (Correct answer)
- Quarterly patient satisfaction score
Correct answer: Hand hygiene compliance rate during rounds
Hand hygiene compliance is a leading indicator because it predicts future infection outcomes, whereas readmission and mortality rates are lagging indicators that reflect past performance.
A hospital's readmission rate is 18%, and the national benchmark is 12%.
After implementing a discharge coaching program, the rate drops to 14%.
This improvement is BEST described as:
