CPHQ Assessment 4 — Questions and Answers
Question 1: A CPHQ professional is assessing workflow efficiency in an emergency department. Which tool would BEST visually map the current state of patient flow steps?
- Control chart
- Value stream map (Correct answer)
- Scatter diagram
- Histogram
Correct answer: Value stream map
Value stream mapping is a lean tool that visually depicts the current state of all steps, delays, and information flows in a process to identify waste and inefficiency.
Question 2: During a medication safety assessment, which measurement level generates the most actionable improvement data?
- Annual aggregate error counts
- Near-miss event rates by medication type and care unit (Correct answer)
- Total pharmacy budget deviation
- Nurse-to-patient staffing ratios
Correct answer: Near-miss event rates by medication type and care unit
Near-miss rates stratified by medication type and care unit provide specific, actionable data that enables targeted interventions before harm occurs.
Question 3: An organization's quality assessment reveals a p-value of 0.03 for an outcome improvement. This means:
- The improvement is clinically significant
- There is a 3% probability the observed result occurred by chance if the null hypothesis is true (Correct answer)
- The intervention caused the improvement
- The sample size was adequate
Correct answer: There is a 3% probability the observed result occurred by chance if the null hypothesis is true
A p-value of 0.03 indicates a 3% probability that the observed difference would occur by chance alone, meeting the conventional threshold for statistical significance.
Question 4: Which approach is used in healthcare quality assessment to compare an organization's performance against top-performing peer organizations?
- Internal auditing
- Benchmarking (Correct answer)
- Root cause analysis
- Variance analysis
Correct answer: Benchmarking
Benchmarking compares an organization's performance metrics against best-in-class or peer organizations to identify performance gaps and improvement opportunities.
Question 5: A quality team conducts a focused review of patients who experienced falls. This type of targeted case review is called:
- Prospective chart audit
- Triggered or occurrence screen review (Correct answer)
- Random concurrent review
- Utilization review
Correct answer: Triggered or occurrence screen review
Triggered or occurrence screening identifies all cases meeting specific criteria (such as a fall) and reviews them in depth to detect patterns and systemic causes.
Question 6: In healthcare quality assessment, which measure type evaluates whether the right care was given at the right time?
- Outcome measure
- Process measure (Correct answer)
- Structure measure
- Balancing measure
Correct answer: Process measure
Process measures assess whether specific evidence-based care steps were performed as intended, evaluating adherence to care protocols and standards.
Question 7: A CPHQ professional designing a patient survey must ensure the instrument measures patient experience, not patient satisfaction. The key distinction is:
- Experience surveys are longer than satisfaction surveys
- Experience surveys capture what happened objectively; satisfaction captures subjective judgment (Correct answer)
- Satisfaction surveys use Likert scales; experience surveys do not
- Experience surveys target inpatients; satisfaction surveys target outpatients
Correct answer: Experience surveys capture what happened objectively; satisfaction captures subjective judgment
Patient experience measures what actually occurred during care (objective events), while satisfaction measures patients' subjective evaluation of whether expectations were met.
