What is population health management and what data sources drive it?

• A. Population health management seeks to improve health outcomes for groups; data sources include claims data, EHRs, patient-reported data, and social determinants information
• B. It focuses only on individual patient encounters and uses hospital derive data only
• C. It relies solely on laboratory data for decision making
• D. It uses only pharmacy claims and prescriber data

Answer: (A)

Population health management is about improving health outcomes for groups by coordinating care across settings and using data to understand patterns, risks, and gaps in care. The data driving it come from multiple sources to give a complete view: claims data show how people use services, what costs occur, and where care patterns emerge; electronic health records provide clinical details like diagnoses, lab results, medications, and care plans; patient-reported data add the patient’s perspective on symptoms, quality of life, and adherence; and information on social determinants of health captures factors such as housing, income, education, food security, transportation, and social context that influence health outcomes and access to care.

Relying on any single data source would leave gaps—for example, focusing only on encounters may miss outpatient and community care and the broader context; using only hospital-derived data misses primary care and social factors; relying solely on laboratory data lacks the clinical decision-making context and outcomes; and limiting to pharmacy claims or prescriber data omits patient experiences and broader care patterns.
