Iowa and Stetler Models of Evidence-Based Practice in Nursing
This paper examines two prominent frameworks for implementing evidence-based practice (EBP) in nursing: the Iowa Model and the Stetler Model. It describes the core features of each model, including the Iowa Model's algorithmic decision points and organizational focus, and the Stetler Model's six-phase process and emphasis on individual clinician judgment. The paper compares the two models across dimensions such as simplicity, applicability, and staff usability, and evaluates their respective strengths and limitations. It concludes by arguing that the Iowa Model is the more appropriate choice for organizational implementation, particularly in acute care settings where interdisciplinary team input and structured pilot testing are priorities.

What makes this paper effective
- The paper presents a clear side-by-side comparison of two nursing EBP frameworks, helping readers understand how each model functions and where each performs best.
- It moves logically from description to comparison to evaluation, giving the argument a coherent structure that builds toward a justified recommendation.
- The use of a concrete clinical example — implementing a critical care examination tool for non-verbal ICU patients — grounds the abstract model discussion in real practice.
Key academic technique demonstrated
This paper demonstrates comparative analysis as an academic technique. Rather than describing each model in isolation, the author systematically contrasts their features — institutional versus individual focus, simplicity versus comprehensiveness, and scope of applicability — before synthesizing the comparison into a reasoned recommendation. This technique is essential in nursing and health sciences writing, where practitioners must evaluate competing frameworks before selecting one for implementation.
Structure breakdown
The paper opens with individual descriptions of the Iowa and Stetler Models, establishing a foundation of understanding for each. It then moves into direct comparison, followed by a balanced assessment of strengths and limitations. The final section applies the analysis to a specific organizational context, recommending the Iowa Model and justifying the choice with a clinical use case. This five-part structure — describe, describe, compare, evaluate, recommend — is a reliable template for framework-selection papers in applied health disciplines.
The Iowa Model of Evidence-Based Practice
Developed by Marita Titler to promote quality healthcare, the Iowa Model of Evidence-Based Practice is a source of guidance for nurses and clinicians when making decisions that affect patient outcomes. It infuses research into practice by using a multidisciplinary team approach to address topics that are clinically important (Melnyk & Overholt, 2011). This model is represented as an algorithm with well-defined feedback loops and decision points. The first decision concerns whether a particular problem is a priority for an organization, and the second decision considers how adequate the evidence is to support a change in practice. After a pilot of the proposed change is conducted on the basis of available evidence, subsequent decisions are made about whether to adopt it, followed by frequent evaluations (Schaffer, Sandau, & Diedrick, 2013).
The Stetler Model of Evidence-Based Practice
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 (Melnyk & Overholt, 2011). The model integrates evidence-informed practice and research use, which supports the application of specific research findings. Within this model, research use is categorized as instrumental, conceptual, or symbolic. The model consists of six phases: preparation, validation, comparative evaluation, decision-making, translation and application, and evaluation (Melnyk & Overholt, 2011).
Comparing the Iowa and Stetler Models
In designing and implementing an EBP project, the Stetler Model relies on the perspectives of individual clinicians, while the Iowa Model focuses primarily on institutional EBP efforts (Melnyk & Overholt, 2011). The Iowa Model does not specify education components, which can make it difficult for nurses to interpret research. The Stetler Model, by contrast, includes evaluation tools that make guideline development more manageable and provides an understandable implementation guide that draws on practitioner expertise and evidence, making it easier for staff nurses to use.
Although the Iowa Model incorporates decision points and feedback loops, most nurses do not prefer it over the Stetler Model. In terms of simplicity, the Iowa Model can be considered more straightforward, as it involves making direct decisions rather than working through six distinct phases. However, the Stetler Model is applicable to both individual patients and organizational systems, as it uses operational definitions and change strategies that provide detailed guidance for practice change (Schaffer, Sandau, & Diedrick, 2013).
