How is risk stratification used in population health?

• A. Classifies patients by disease name only.
• B. Allocates resources based on random assignment.
• C. Evaluates hospital profitability.
• D. Classifies patients by likelihood of adverse events to target interventions and allocate resources.

Answer: (D)

In population health, risk stratification uses patient data to estimate how likely someone is to experience an adverse health event, such as hospitalization or deterioration of a condition. This helps health teams identify who is at higher risk and tailor care accordingly. By knowing who is most at risk, resources and interventions can be directed where they’ll have the greatest impact—for example, more intensive care management, proactive outreach, home visits, or added monitoring for high-risk patients. This approach improves outcomes and makes resource use more efficient by preventing problems before they escalate. It’s not simply grouping patients by disease name, which doesn’t address risk, nor is it about random resource allocation. It also isn’t about measuring profitability of a hospital.
