Question 1: Which data visualization best shows the geographic distribution of disease incidence across US counties?
- Bar chart
- Scatter plot
- Choropleth map (Correct answer)
- Gantt chart
Correct answer: Choropleth map
A choropleth map uses shading or color intensity to display geographic variation in data such as disease incidence.
Question 2: HEDIS measures are used primarily to evaluate performance in which setting?
- Hospital inpatient care
- Managed care health plans (Correct answer)
- Long-term care facilities
- Emergency departments
Correct answer: Managed care health plans
HEDIS (Healthcare Effectiveness Data and Information Set) measures are used by managed care plans to evaluate quality of care.
Question 3: What is the primary purpose of a clinical data warehouse in population health?
- Storing patient billing records only
- Aggregating clinical data from multiple sources for analysis (Correct answer)
- Generating real-time alerts for clinicians
- Replacing the EHR system
Correct answer: Aggregating clinical data from multiple sources for analysis
A clinical data warehouse integrates and aggregates data from multiple sources to support population-level analysis and reporting.
Question 4: Social determinants of health (SDOH) data are increasingly incorporated into analytics because they:
- Reduce the need for clinical documentation
- Help explain health disparities and target interventions (Correct answer)
- Replace ICD-10 coding in claims data
- Are required by HIPAA for all providers
Correct answer: Help explain health disparities and target interventions
SDOH data such as housing, income, and education explain health disparities and help direct community-level interventions.
Question 5: A health informatician calculates the rate of diabetes diagnoses per 1,000 members in a health plan each year. This is an example of:
- Point prevalence
- Incidence rate (Correct answer)
- Case fatality rate
- Standardized mortality ratio
Correct answer: Incidence rate
An incidence rate measures the number of new cases of a condition occurring in a defined population over a specific time period.
Question 6: Which of the following is a key component of a triple aim framework in population health?
- Increasing hospital bed capacity
- Improving care experience, improving population health, and reducing per capita costs (Correct answer)
- Expanding the number of specialist physicians
- Automating all clinical workflows with AI
Correct answer: Improving care experience, improving population health, and reducing per capita costs
