Which of the following is NOT one of Starfield's four functions of primary care?

• A. Coordination
• B. First Contact Care
• C. Screening for Rare Diseases
• D. Longitudinality

Answer: (C)

Starfield’s framework for primary care centers on four functions: being the first point of contact in the health system, providing ongoing care over time (longitudinality), coordinating care with other parts of the health system, and delivering care that covers a broad range of health needs (comprehensiveness). Screening for rare diseases isn’t one of these core functions. Primary care does include preventive screening for common conditions as part of comprehensive care, but screening specifically for rare diseases isn’t a general, defining function of primary care in Starfield’s model. The other options align with those four functions: acting as the entry point, maintaining an ongoing patient relationship, and coordinating with specialists and services.
