HAC Healthcare Analytics Performance Measurement & Reporting 3 — Questions and Answers
Question 1: Which concept describes the process of adjusting outcome metrics to account for differences in patient severity across provider organizations?
- Benchmarking
- Risk adjustment (Correct answer)
- Stratification
- Normalization
Correct answer: Risk adjustment
Risk adjustment controls for patient severity and comorbidities to enable fair comparisons of outcomes across providers.
Question 2: A performance dashboard shows that a clinic's diabetes HbA1c control rate dropped from 68% to 61% over one quarter. Before drawing conclusions, the analyst should FIRST:
- Immediately report the finding to administration as a quality failure
- Verify data integrity and check for coding or reporting changes during the period (Correct answer)
- Implement a new diabetes management protocol
- Compare the rate only to national benchmarks
Correct answer: Verify data integrity and check for coding or reporting changes during the period
Data quality verification ensures that apparent performance changes are real and not artifacts of coding, reporting, or data extraction changes.
Question 3: The HEDIS measure 'Controlling High Blood Pressure' specifies a blood pressure threshold of less than 140/90 mmHg. This is an example of which type of quality measure?
- Structure measure
- Process measure
- Intermediate outcome measure (Correct answer)
- Patient experience measure
Correct answer: Intermediate outcome measure
Controlled blood pressure is an intermediate outcome — a physiologic result that serves as a proxy for long-term clinical outcomes.
Question 4: Which reporting framework requires hospitals to publicly report on patient safety indicators, hospital-acquired conditions, and value-based purchasing scores?
- HEDIS
- Joint Commission ORYX
- CMS Hospital Compare / Care Compare (Correct answer)
- NCQA Accreditation Standards
Correct answer: CMS Hospital Compare / Care Compare
CMS Care Compare publicly reports hospital quality data including PSIs, HACs, and VBP performance for Medicare-certified hospitals.
Question 5: An analyst notices that a run chart of weekly patient falls shows a shift (eight consecutive points on the same side of the median). This pattern indicates:
- Random common-cause variation
- A non-random signal suggesting a real process change (Correct answer)
- Seasonal variation in falls risk
- Insufficient sample size to draw conclusions
Correct answer: A non-random signal suggesting a real process change
Eight consecutive points on the same side of the median is a recognized run chart rule indicating a non-random shift in the process.
Question 6: In population health analytics, which measure best quantifies the gap between current care delivery and evidence-based best practice for a defined patient cohort?
- Prevalence rate
- Care gap rate (Correct answer)
- Incidence density
- Comorbidity index
Correct answer: Care gap rate
A care gap rate measures the proportion of eligible patients who have not received a recommended evidence-based service or treatment.
Question 7: A hospital is measuring its Observed-to-Expected (O/E) mortality ratio. An O/E ratio of 0.78 should be interpreted as:
- Mortality is 22% higher than expected given patient risk
- Mortality is 22% lower than expected given patient risk (Correct answer)
- 78% of patients who were expected to die actually died
- The hospital's mortality data is incomplete by 22%
Correct answer: Mortality is 22% lower than expected given patient risk
An O/E ratio below 1.0 means observed deaths are fewer than risk-adjusted predictions, indicating better-than-expected performance.
