Which level of care accounts for 80% to 90% of visits to a clinician?

• A. Quaternary
• B. Secondary
• C. Tertiary
• D. Primary

Answer: (D)

Primary care handles the broad, everyday health needs of most people. It’s the first contact, ongoing, comprehensive care delivered by generalists (like family medicine, internal medicine, and pediatrics) who manage a wide range of conditions and provide preventive services. Because so many visits involve common illnesses, routine screenings, and chronic disease management that don’t require specialized procedures, primary care sees the largest share of clinician visits—roughly 80% to 90%. When issues are more complex or specialized, patients are referred to secondary care (specialists) and, if needed, to tertiary or quaternary centers for highly advanced care. So this level most accurately reflects where the majority of visits occur.
