Study Notes
Evidence Types
- Expert opinion based on non-research evidence includes case studies, literature reviews, and personal experiences.
- Different levels of evidence quality exist, ranging from high (well-defined strategies and consistent results) to low (poorly defined searches and insufficient evidence).
Quality of Evidence (Summary Review)
- Level A (High): Well-defined research methods, consistent results, numerous well-designed studies, and thorough evaluation of scientific strength and limitations.
- Level B (Good): Reasonable search and results consistency, sufficient quality studies, and some evaluation of strength and limitations.
- Level C (Low): Inadequate and poorly defined searches, inconsistent results, and inconclusive outcomes.
Quality of Evidence (Expert Opinion)
- High: Expertise is clearly established.
- Good: Credible expertise is present, though less evident.
- Low: Expertise lacks discernibility or appears dubious.
Evidence Summary
- A systematic table outlines the title, publication date, purpose, design, and level of evidence for 6-7 articles.
Critical Appraisal Considerations
- Examine whether authors’ opinions are clear and biases acknowledged.
- Verify if search strategies are specified, reproducible, and appropriate.
- Criteria for inclusion/exclusion of studies should be clearly defined.
- Ensure methodological limitations and variable similarities in studies are disclosed.
Non-Research Evidence Appraisal
- Level IV includes systematic reviews and clinical practice guidelines, focusing on evidence synthesis from research studies.
- Level V is categorized as weak evidence, based on quality improvement studies and financial analyses.
Clinical Practice Guidelines
- Guidelines based on scientific findings, clinician expertise, and patient preferences guide decision-making.
- Validation of guidelines should include reproducibility, stakeholder involvement, and clarity in recommendations.
Meta-Synthesis
- A research technique analyzing qualitative studies to identify key concepts and their relationships without producing a summary statistic.
Research Evidence Quality
- High quality includes consistent results, adequate controls, and definitive conclusions.
- Good quality shows reasonably consistent results with some limitations in findings.
- Low quality indicates insufficient evidence leading to inconclusive conclusions.
Research and Non-Research Evidence Appraisal Tools
- Analytical process involves checking study applicability to the target population.
- Systematic reviews should have clear questions and rigorous peer-review processes.
Initial Evidence-Based Practice (EBP) Questions
- Formulate EBP questions, identify search terms, and employ diverse databases for comprehensive evidence gathering.
- Consider regulatory guidelines, expert opinions, and patient-centered preferences during evidence collection.
Evidence-Based Nursing Practice Toolkit
- Adapted from The Johns Hopkins Nursing Evidence-Based Practice Model, designed for KFSH&RC-Jeddah by Gillian Sedgewick.
- The toolkit facilitates the development and implementation of evidence-based practice in nursing.
Key Components of the Evidence-Based Practice Model
- Emphasis on identifying the problem and articulating its significance.
- Current practice evaluation must consider clinical, educational, and organizational perspectives.
- Establishment of a PICO framework:
- P = Population
- I = Intervention
- C = Comparison
- O = Outcome
Problem Identification and Scope
- Problems can be identified through safety/risk management, quality concerns, satisfaction issues, or variations in practice.
- The scope may be individual, population-focused, or organizational/systemic.
Evidence Gathering Strategies
- Extensive search of databases and exploration of diverse evidence sources, including:
- Regulatory and professional standards
- Clinical guidelines and expert opinions
- Patient family preferences
- Both internal and external data sources
Literature Review and Appraisal
- Dual appraisal tools for both research and non-research evidence:
- Research evidence includes experimental studies, meta-analyses, and qualitative research.
- Non-research includes systematic reviews and clinical practice guidelines.
- Research knowledge is evaluated for strength, relevance, bias acknowledgment, and overall applicability to practice questions.
Rating and Quality Assessment
- Ratings categorize evidence from Level I (strong) to Level V (weak).
- Quality of evidence is assessed based on research strategy robustness and consistency of results.
- Guidelines must demonstrate stakeholder involvement, clear application groups, and reproducible recommendations.
Evidence Summary Documentation
- A structured format to summarize evidence findings including title, purpose, method/design, and evidence level.
- Key points from each article investigated should be chronicled for clarity in decision-making.
Critical Evaluation of Sources
- Assessment of the validity and reliability of evidence, ensuring search strategies are reproducible and comprehensive.
- Inclusion and exclusion criteria must be defined for selecting studies to ensure methodological rigor.
Conclusion and Implementation
- Integration of evidence into practice must prioritize clear, actionable recommendations.
- Continuous evaluation and adaptation of practices based on new evidence and stakeholder feedback are vital for nursing excellence.
