Which of the following best captures the core outcomes used to evaluate the US healthcare system?

• A. Utilization, quality measures, access, and equity
• B. Cost, efficiency, access, and quality
• C. Cost, quality, access, and equity
• D. Quality, safety, staffing, and reimbursement

Answer: (C)

Evaluating a health system effectively rests on four key dimensions: cost, quality, access, and equity. Cost shows whether care is affordable and sustainable for individuals and the system as a whole. Quality reflects how well care achieves desired health outcomes and safety, including effectiveness and patient experiences. Access measures whether people can obtain the care they need in a timely and convenient way. Equity ensures that improvements reach all groups and that disparities by race, income, geography, or other factors are not ignored.

Why this combination fits best is that it covers both value and fairness in care. Some other sets mix in utilization, safety, staffing, or reimbursement. Utilization describes actual use rather than the system’s performance on affordability or fairness. Safety and staffing are important components of quality but are more specific elements than the broader outcome of quality itself. Reimbursement relates to financing rather than an outcome. The four dimensions above—cost, quality, access, and equity—together map to the central goals policymakers seek: affordable care, high-quality outcomes, broad and timely access, and fair distribution of benefits.
