Population health management uses data to identify and target high-risk or high-utilization patients for interventions to improve outcomes and reduce costs.
Option A (Cold-spotting): Cold-spotting identifies areas or populations with low healthcare utilization, not relevant to high ER use.
Option B (Hot-spotting): This is the correct answer. The NAHQ CPHQ study guide states, “Hot-spotting is a population health technique that identifies patients with high healthcare utilization, such as frequent ER visits, for targeted interventions” (Domain 5). Developed by Dr. Jeffrey Brenner, it focuses on high-cost, high-need patients.
Option C (Syndromic surveillance): This monitors disease patterns (e.g., flu outbreaks), not individual utilization.
Option D (Public health surveillance): This tracks population-level health trends, not individual high utilizers.
CPHQ Objective Reference: Domain 5: Population Health and Care Transitions, Objective 5.2, “Apply population health management techniques,” includes hot-spotting for high-risk patients. The NAHQ study guide notes, “Hot-spotting targets high-utilization patients to reduce costs and improve care” (Domain 5).
Rationale: Hot-spotting directly addresses frequent ER users, aligning with CPHQ’s population health strategies.
