This paper examines two foundational frameworks for implementing evidence-based practice (EBP) in healthcare: the Iowa Model and the Stetler Model. The Iowa Model, developed by Marita Titler, emphasizes organizational-level implementation through multidisciplinary teams and decision-point algorithms. The Stetler Model focuses on individual clinician assessment and includes six structured phases for evaluating and applying research. The paper compares their design philosophies, evaluates their respective strengths and limitations, and discusses applicability across different healthcare settings. While the Stetler Model offers detailed guidance suitable for both individual and organizational levels, the Iowa Model is concluded to be most appropriate for acute care environments in large organizations due to its systematic approach to organizational implementation and inclusion of nursing input at every stage.
Developed by Marita Titler to promote quality healthcare, the Iowa Model is a source of guidance for nurses and clinicians when making decisions that have an impact on patient outcomes. It infuses research into practice by using a multidisciplinary team approach to address a number of topics that are clinically important (Melryk and Overholt, 2011). This model is represented as an algorithm that has well-defined feedback loops as well as decision points. The first decision concerns whether a particular problem is a priority to an organization, and the second decision considers whether the available evidence is adequate to support a change in practice. After conducting a pilot of the proposed change based on available evidence, subsequent decisions are made regarding whether to adopt it, which is followed by frequent evaluations (Schaffer, Sandau and Diedrick, 2013).
The Stetler Model of Evidence-Based Practice (EBP) enables practitioners to assess how research findings can be applied in practice. It helps nurses use evidence to make formal changes in organizations and enhances reflective practice and critical thinking (Melryk and Overholt, 2011). The model integrates evidence-informed practice and research use, which enhances the application of specific research. Using this model, research use is categorized into instrumental, conceptual, and symbolic use. The model has six phases: preparation, validation, comparative evaluation, decision making, translation and application, and evaluation (Melryk and Overholt, 2011).
In the designing and implementing of an EBP project, the Stetler Model relies on the perspectives of individual clinicians, while the main focus of the Iowa Model is on institutional EBP efforts (Melryk and Overholt, 2011). The Iowa Model does not specify education components, which makes it difficult for nurses to interpret research findings. In contrast, the Stetler Model has evaluation tools that facilitate guideline development, making it easier for staff nurses to use. It provides an understandable guide for implementation and makes use of practitioner expertise and evidence.
Although the Iowa Model incorporates decision points and feedback loops, most nurses prefer the Stetler Model over it. In terms of simplicity, the Iowa Model can be characterized as straightforward because it involves making direct decisions, as opposed to the Stetler Model, which requires working through six phases. However, the Stetler method is applicable to both individual patients and organizational systems because it uses operational definitions and change strategies that provide detailed guidance for practice change (Schaffer, Sandau and Diedrick, 2013).
One of the key disadvantages of the Iowa Model is that it makes it difficult for nurses to interpret results and implement changes in their practice. The lack of detailed guidance on how to educate staff about the practice change is also detrimental (Schaffer, Sandau and Diedrick, 2013). However, multiple reports have demonstrated successful application of this model in a wide range of scenarios. The model also takes into consideration input from the whole organizational system and involves nurses at every step of the process.
The Stetler Model is prone to interpretation mistakes, and research information from different professionals must be treated with caution. Its main advantage is that it takes characteristics of individual users into account and uses comprehensive guides for implementation. The Stetler Model is applicable to both individuals and organizations, making available critical guidance and expertise for EBP practitioners with relevant experience in diverse settings. The Iowa Model is also useful in a variety of settings, but it is best suited for acute care in large organizations.
