What is the purpose of the Iowa Model of Evidence-Based Practice?

• A. To replace clinical judgment with research findings.
• B. To promote quality care through structured evidence-based practice.
• C. To evaluate hospital accreditation standards.
• D. To design patient education materials.

Answer: (B)

The main idea is to use a structured, evidence-based approach to improve nursing care. The Iowa Model of Evidence-Based Practice provides a step-by-step framework to translate research into practice, guiding nurses from recognizing a problem or knowledge gap to implementing changes and evaluating outcomes. It begins with recognizing a trigger (problem-focused or knowledge-focused), forming a team, and framing a clinical question, then searching for and critically appraising the best evidence. If the evidence supports a change, a plan is designed, tested, and implemented, with ongoing evaluation and dissemination of results. This process emphasizes quality care by grounding practice decisions in solid evidence while considering patient preferences and local context. It does not replace clinical judgment; rather, it complements it by informing decisions with research. It isn’t about evaluating accreditation standards or solely designing patient education materials, though education and standards can be affected by the resulting changes.
