Which statement best differentiates research evidence, patient evidence, and clinical expert evidence?

• A. Research evidence is the results of scientific research; patient evidence comprises values, preferences, expectations, and circumstances; clinical expert evidence is personal knowledge, expertise, and expectations perhaps from established experts
• B. They are all the same
• C. Patient evidence is the only evidence that matters
• D. Clinical expert evidence is based on devices and machines

Answer: (A)

In evidence-based practice, the three kinds of evidence that guide decisions are research evidence, patient evidence, and clinical expert evidence. Research evidence comes from scientific studies and systematic reviews, providing information on what tends to work and the balance of benefits and harms across populations. Patient evidence captures values, preferences, expectations, and individual circumstances, showing what matters most to the person and what they’re willing to accept. Clinical expert evidence reflects the clinician’s knowledge, experience, and judgment—the ability to interpret the research and apply it to a specific patient’s situation. The best answer confirms this clear separation: research evidence provides generalizable findings from science, patient evidence centers on the patient’s values and context, and clinical expert evidence represents the clinician’s informed judgment to tailor decisions. The other options either collapse these distinctions, misstate what matters for decision-making, or misattribute the source (for example, equating clinical expert evidence with devices or machines).
