Which statement correctly differentiates QA, QI, and Evaluation?

Which statement correctly differentiates QA, QI, and Evaluation?

• A. QA meets minimum standards, QI is a continuous process change, and Evaluation determines effectiveness and impact.
• B. QA is about patient satisfaction, QI is about budgeting, Evaluation is only risk assessment.
• C. QA measures only outcomes, QI never uses data, Evaluation is ongoing.
• D. QA and QI are the same, Evaluation is irrelevant.

Answer: (A)

Understanding how QA, QI, and Evaluation differ helps you see why that statement is correct. Quality Assurance focuses on meeting minimum standards and ensuring that activities conform to required rules and processes. It’s about consistency and compliance, not necessarily about making improvements beyond what’s required. Quality Improvement is the ongoing, systematic effort to change and optimize processes to achieve better results. It relies on data, frequent testing of small changes, and iterative cycles to move performance forward. Evaluation, on the other hand, looks at what the program or service actually achieved in terms of effectiveness and impact, providing evidence about outcomes and overall value. So the best choice captures these distinct roles: QA meets minimum standards, QI is a continuous process of change to improve performance, and Evaluation determines effectiveness and impact. The other statements mix up focus areas (for example, tying QA to patient satisfaction or misclaiming QI doesn’t use data), or claim QA and QI are the same or that Evaluation isn’t relevant, which doesn’t align with how these activities function in public health practice.
