Evidence-Based Practice - Essay Example

Consistency is necessary for reliability because models have different elements and procedures that could initiate differences in results. Identifying and relying on a single model, however, resolves this and allows for a basis for comparisons. Repeated application of a model also ensures competence in its application for better accurate evidence.

The four models are similar in their methodology to evidence-based practice in that they are structured. The Stetler model has five major steps: “preparation,” “validation,” “comparative evaluation,” “application,” and “evaluation” (Profetto-McGrath, Polit, & Beck, 2010, p. 376, 377). The IOWA model identifies such steps as recognizing triggers, evaluating priority, identifying of problems, and implementing a change (Profetto-McGrath, Polit, & Beck, 2010). Despite the existence of well-defined methodologies in the models, each model has its specific procedure and this establishes the models’ differences (Profetto-McGrath, Polit, & Beck, 2010; Ackley, 2008).

The models are also suitable for different areas of specialization. While the IOWA model is suitable for practice in areas with limited evidence, the John Hopkins model is suitable for scientific research and Rosswurn & Larrabee model is suitable for acute care scenarios (Rempher, 2006).In selecting a model for a setting, I would consider the suitability of the model for the setting and the complexity of the problem. This is because the factors are significant to the successful interpretation of evidence (Profetto-McGrath, Polit, & Beck, 2010).
