CPHRM Quality Improvement 3 — Questions and Answers
Question 1: A Pareto chart is used in quality improvement to:
- Track data trends over a specific time period
- Identify the few causes responsible for most problems (Correct answer)
- Compare performance between two hospital units
- Map all possible causes of a quality problem
Correct answer: Identify the few causes responsible for most problems
A Pareto chart displays problems in descending frequency to identify the vital few causes that account for most errors, based on the 80/20 rule.
Question 2: In healthcare quality improvement, 'benchmarking' refers to:
- Setting internal performance goals based on last year's data
- Comparing performance metrics against best practices or top performers (Correct answer)
- Measuring patient satisfaction scores on a standardized survey
- Reviewing individual clinician performance annually
Correct answer: Comparing performance metrics against best practices or top performers
Benchmarking compares an organization's processes and outcomes against recognized leaders or industry standards to identify performance gaps.
Question 3: Which quality improvement tool would be MOST appropriate for identifying all possible causes of medication errors in an emergency department?
- Run chart
- Fishbone (Ishikawa) diagram (Correct answer)
- Scatter diagram
- Histogram
Correct answer: Fishbone (Ishikawa) diagram
A fishbone diagram organizes potential causes of a problem into categories (people, process, equipment, environment) to facilitate comprehensive root cause exploration.
Question 4: A hospital's quality improvement team wants to test a small-scale change before full implementation. They should use which model?
- Six Sigma DMAIC
- Plan-Do-Study-Act (PDSA) cycle (Correct answer)
- Lean value stream mapping
- FMEA prospective analysis
Correct answer: Plan-Do-Study-Act (PDSA) cycle
The PDSA cycle is designed for small, rapid tests of change that allow teams to learn and refine interventions before broad implementation.
Question 5: Patient harm events are classified by severity level. Which classification system does the National Coordinating Council for Medication Error Reporting and Prevention (NCC MERP) use?
- A through I index categories (Correct answer)
- Level 1 through Level 5 severity scale
- Green, Yellow, Red risk classification
- Minor, Moderate, Major, Catastrophic tiers
Correct answer: A through I index categories
NCC MERP uses Categories A through I to classify medication errors from no harm potential (A) to death (I).
Question 6: Which of the following BEST describes 'high reliability organizations' (HROs) in healthcare?
- Organizations with zero employee turnover and high patient volume
- Organizations that consistently minimize harm despite operating in complex, high-risk environments (Correct answer)
- Organizations that exceed benchmarks in patient satisfaction scores only
- Organizations accredited by multiple regulatory agencies simultaneously
Correct answer: Organizations that consistently minimize harm despite operating in complex, high-risk environments
HROs are characterized by a persistent preoccupation with failure, sensitivity to operations, commitment to resilience, and deference to expertise at all levels.
Question 7: In quality improvement, a 'tracer methodology' used by The Joint Commission involves:
- Tracking financial costs of adverse events across departments
- Following a patient's care experience through the organization to evaluate system performance (Correct answer)
- Tracing the source of a healthcare-associated infection outbreak
- Monitoring staff compliance with hand hygiene protocols via observation
Correct answer: Following a patient's care experience through the organization to evaluate system performance
Tracer methodology follows an individual patient's care journey through the organization to evaluate actual compliance with standards and identify system gaps.
