Healthcare Systems and Delivery Models
What to know
Candidates should be able to distinguish the major delivery structures: solo and group practices, ambulatory clinics, community hospitals, academic medical centers, integrated delivery systems (IDS), accountable care organizations (ACOs), and government-run systems (VA, IHS, public health departments). Tie each model to its ownership (public, nonprofit, for-profit), payment posture (fee-for-service vs. capitation vs. shared savings), and care-continuum breadth. Understand the payer mix concept and how safety-net providers differ from market-dominant systems. Know the basic vocabulary of the triple/quadruple aim, population health, and care coordination.
Traps
Questions often blur delivery models with payment models. An IDS is a structural arrangement; an ACO is a payment-and-accountability arrangement that may sit inside an IDS. Another common trap is confusing nonprofit status with charitable behavior-nonprofits still bill and collect. Watch for "always/never" absolutes about which model improves quality; evidence is context-dependent.
Worked example
A question describes a hospital, a physician group, and a health plan under common ownership sharing a single EHR and budget. The correct label is an integrated delivery system with aligned financing-not merely an ACO, because ownership and shared infrastructure are described. Rule of thumb: structure = who owns what; payment = how money flows; accountability = who bears risk.
Focus study on how rural, urban safety-net, and academic settings differ in mission and payer mix, since scenario questions frequently test those distinctions.
