HAC Patient Outcome Measurement 2 — Questions and Answers
Question 1: Which statistical method is most appropriate for analyzing time-to-event patient outcome data such as survival or readmission?
- Kaplan-Meier analysis (Correct answer)
- Linear regression
- Chi-square test
- ANOVA
Correct answer: Kaplan-Meier analysis
Kaplan-Meier analysis handles censored time-to-event data, making it ideal for survival and readmission outcome studies.
Question 2: A hospital wants to compare 30-day readmission rates across different socioeconomic groups. Which adjustment is most critical before drawing conclusions?
- Risk adjustment for comorbidities and social determinants (Correct answer)
- Excluding patients with chronic conditions
- Using only Medicare data
- Limiting analysis to elective admissions
Correct answer: Risk adjustment for comorbidities and social determinants
Risk adjustment accounts for differences in patient complexity and social factors that independently influence readmission rates.
Question 3: The PROMIS (Patient-Reported Outcomes Measurement Information System) uses which technology to efficiently administer questionnaires?
- Computer adaptive testing (CAT) (Correct answer)
- Paper-based Likert scales
- Structured clinical interviews
- Laboratory biomarkers
Correct answer: Computer adaptive testing (CAT)
PROMIS uses computer adaptive testing to dynamically select questions based on prior responses, reducing burden while maintaining precision.
Question 4: Which outcome domain does the SF-36 instrument primarily measure?
- Health-related quality of life across eight dimensions (Correct answer)
- Clinical laboratory values
- Hospital operational efficiency
- Provider satisfaction scores
Correct answer: Health-related quality of life across eight dimensions
The SF-36 measures eight health domains including physical functioning, bodily pain, general health, and mental health to assess HRQoL.
Question 5: When an outcome measure shows consistent results across repeated administrations under the same conditions, it demonstrates which psychometric property?
- Reliability (Correct answer)
- Validity
- Responsiveness
- Feasibility
Correct answer: Reliability
Reliability refers to the consistency and reproducibility of a measurement instrument over repeated administrations.
Question 6: A patient-reported outcome instrument that can detect meaningful changes in health status over time demonstrates which property?
- Responsiveness (Correct answer)
- Internal consistency
- Face validity
- Ceiling effect
Correct answer: Responsiveness
Responsiveness (also called sensitivity to change) is the ability of an instrument to detect clinically meaningful changes in patient condition.
Question 7: Which CMS program ties hospital reimbursement to patient outcome measures including mortality and readmission rates?
- Hospital Value-Based Purchasing (VBP) (Correct answer)
- Meaningful Use Program
- Stark Law Compliance
- Medicare Shared Savings Program
Correct answer: Hospital Value-Based Purchasing (VBP)
The Hospital Value-Based Purchasing program adjusts Medicare payments based on clinical outcome measures, patient experience, and efficiency metrics.
