Models of evidence-based practice

Comparing Models of Evidence-Based Practice (EBP)

Evidence-based practice (EBP) is fundamental to providing high-quality healthcare. However, putting EBP into action can be complex. Numerous models have been developed to guide healthcare professionals in applying research findings to real-world clinical practice. This article compares several popular EBP models for clinical decision-making, examining their strengths, limitations, and how well they apply in different settings.

Iowa Model of Evidence-Based Practice

The Iowa Model is a widely used framework for implementing EBP in healthcare organizations. It provides a systematic approach to:

• Identifying problems in practice.
• Finding and critically evaluating research evidence.
• Implementing and evaluating changes in practice based on the evidence.

Model for Evidence-Based Practice Change

This model focuses on the process of translating research findings into actual practice changes. It emphasizes the importance of:

• Understanding the organizational context where the changes will be implemented.
• Involving key stakeholders in the process to ensure successful EBP implementation.

Clinical Scholar Model

The Clinical Scholar Model encourages nurses to develop strong research skills and apply them to their clinical practice. It emphasizes:

• Critical thinking and problem-solving.
• Lifelong learning and continuous professional development.

Johns Hopkins Nursing Evidence-Based Practice Model

This model provides a practical, three-step process for implementing EBP:

1. Asking focused clinical questions.
2. Finding and appraising evidence.
3. Translating research into practice.

Stetler Model of Research Utilization

The Stetler Model is a comprehensive framework that guides the entire process of research utilization, from identifying a problem to evaluating the outcomes of implementing evidence-based changes.

The Advancing Research and Clinical Practice Through Close Collaboration (ARCC) Model

The ARCC Model focuses on building organizational capacity for EBP. It emphasizes the importance of:

• Mentorship to guide and support nurses in EBP.
• Strong leadership to drive EBP implementation.
• A supportive organizational culture that values EBP.

The Promoting Action on Research Implementation in Health Services (PARIHS) Framework

The PARIHS Framework highlights how evidence, context, and facilitation interact to successfully implement EBP. It emphasizes the importance of tailoring interventions to the specific needs of the healthcare setting.

Key Considerations When Choosing an EBP Model

Components

Each EBP model has unique components and steps. Consider which model best aligns with your needs and the resources available.

Simplicity vs. Complexity

Some models are more complex than others. Choose a model that is appropriate for your level of experience and the complexity of the problem you are addressing.

Ease of Use for Nurses

Consider how easy the model is to understand and use for staff nurses. A user-friendly model is more likely to be adopted and implemented effectively.

Applicability to Systems and Individual Patients

Some models are better suited for implementing EBP across healthcare systems, while others are more focused on individual patient care.

Strengths and Limitations

Each model has its own strengths and limitations. Carefully evaluate these factors when choosing a model for your specific needs.

Addressing Criticisms of Evidence-Based Practice

While evidence-based practice has many benefits, it also has its critics. Some common criticisms include:

• EBP ignores patient or community input: This criticism highlights the importance of incorporating patient preferences and values into EBP decision-making.
• EBP stifles creative problem solving and clinical judgment: While EBP emphasizes research evidence, it’s important to balance this with clinical expertise and patient-centered care.
• EBP emphasizes quantitative research and randomized controlled trial (RCT): While RCTs are considered the gold standard, EBP also values qualitative research and other forms of evidence.
• EBP disregards clinical expertise: EBP recognizes the importance of integrating clinical expertise with research evidence.
• EBP supports generalizing results to populations not studied: It’s crucial to critically evaluate research findings and consider their applicability to specific patient populations.
• EBP is simply another term for research utilization: While research utilization is a key component of EBP, it also encompasses clinical expertise and patient preferences.
