EBP-Assessment

Learning Objectives

  • Discuss essential elements in the use of evidence-based practice (EBP).

  • Identify reliable sources for obtaining evidence-based information.

  • Discuss the application of EBP in guiding nursing care delivery.

Scope of Practice

  • Differences in scope of practice between Registered Nurses (RNs) and Practical Nurses (PNs):

    • Registered Nurses (RNs) typically have a broader scope of practice, including assessment, diagnosis, management, and evaluation of patient care.

    • Practical Nurses (PNs) often assist RNs and may provide basic patient care, administer medications, and monitor patient status under RN supervision.

  • Call out boxes should highlight PN practice considerations:

    • PN scope varies significantly by state law; some states allow PNs to contribute to care plans, while others restrict them to implementation rather than development.

    • Most states require PNs to operate under the supervision of an RN, which emphasizes the importance of teamwork in nursing practice.

  • PN students are required to align discussions and educational experiences with their state’s specific scope of practice.

  • It is essential for PNs to understand and adhere to state guidelines for safe practice, ensuring that they are competent and compliant in their roles.

Evidence-Based Practice (EBP)

  • Definition:

    • EBP is the systemic process of using the most current, credible scientific literature to inform nursing practice decisions. This includes integrating individual clinical expertise with the best available external clinical evidence.

  • Types of Researches In EBP:

    • Quantitative Research: Focuses on numerical data and statistical methods to quantify outcomes. Common methods include randomized controlled trials, cohort studies, and case-control studies.

    • Qualitative Research: Explores underlying reasons, opinions, and motivations, often using interviews, focus groups, or observations. This type of research helps to understand the context of patient experiences.

    • Mixed Methods Research: Combines both quantitative and qualitative approaches to provide a comprehensive analysis of a research question. This approach may offer more holistic insights into clinical practices.

    • Systematic Reviews and Meta-Analyses: High-level research that synthesizes findings from multiple studies to draw robust conclusions regarding treatment effectiveness or practice guidelines.

    • Clinical Practice Guidelines: Evidence-based recommendations developed by expert panels using systematic review processes to inform practice decisions on specific conditions.

  • Impact:

    • EBP aims to positively affect client outcomes through informed practice, ensuring that healthcare interventions are grounded in solid research.

    • EBP involves evaluating scientific findings to establish evidence-based recommendations that are implemented and regularly reevaluated by measuring client outcomes for effectiveness.

  • Benefits of EBP:

    • Improved client outcomes, as interventions based on sound evidence are more likely to succeed.

    • Reduced health care costs due to decreased patient complications and enhanced resource utilization.

    • Enhanced delivery of high-quality healthcare services that meet contemporary healthcare demands.

    • Increased satisfaction for both nurses and clients as a result of evidence-based interventions enhancing care quality.

    • A gradual shift from traditional methods to a focus on nurse-led research over time, encouraging nurses to engage in studies that can improve their practice.

Essential Components of EBP

According to the American Nurses Association, EBP should ensure:

  • Holistic and Quality Care: Based on the latest research and practices, incorporating aspects of physical, emotional, and social wellness.

  • Focus on the Spirit of Inquiry:

    • A foundational driver of EBP, the spirit of inquiry encourages nurses and healthcare professionals to seek to understand and integrate new knowledge into their care practices.

    • It promotes questioning traditional practices to update and refine them based on current scientific evidence.

EBP Process Steps

  1. Identify a Problem: Recognize a clinical or systemic issue that may impact patient care.

  2. Ask a Question: Develop a specific clinical question, employing the PICO format to ensure clarity and relevance:

    • Population: Whom does the problem affect?

    • Intervention: What intervention can be applied?

    • Comparison: What is the alternative or comparison group?

    • Outcome: What are the expected results?

    • Time: Identify any timelines if relevant.

  3. Search for Evidence: Conduct a comprehensive literature search across credible sources, utilizing databases and scholarly articles.

  4. Evaluate Findings: Assess research for relevance, validity, and applicability concerning the clinical question.

  5. Implement Recommendations: Apply changes in practice based on the evaluated evidence, integrating them into routine care.

  6. Evaluate Effectiveness: Collect data post-implementation to assess whether the changes in practice have improved client outcomes.

  7. Disseminate Results: Share the findings with colleagues through presentations, workshops, or publications to facilitate broader understanding and application of EBP.

Examples of EBP in Nursing

  • Oxygen use in hypoxia management, where evidence supports specific administration techniques to optimize patient safety.

  • Antibiotic stewardship protocols that guide appropriate use to mitigate resistance and infections effectively.

  • Fall prevention measures informed by research identifying high-risk factors and intervention options.

Searching for Reliable Evidence Sources

  • Scholarly Databases:

    • Utilize academic library resources and databases, enabling access to peer-reviewed literature. Examples include:

      • Cochrane Library

      • CINAHL (Cumulative Index to Nursing and Allied Health Literature)

      • PubMed

  • Government and Nonprofit Websites:

    • Access reliable information from agencies such as the CDC (Centers for Disease Control and Prevention) or the American Heart Association.

    • Critically assess the credibility of non-academic sources, evaluating the expertise of authors, evidence of updates, and the intended purpose of the material.

Evaluation and Appraisal of Evidence

  • Must review research for:

    • Validity: Assessing the quality of the study, including design and execution.

    • Reliability: Evaluating whether study results are consistent across different investigations.

    • Applicability: Determining the relevance of findings to current nursing practice and understanding clinical settings.

Hierarchy of Evidence

  • Utilizes a system that ranks evidence from Level I (systematic reviews/meta-analysis) to Level VII (expert opinions). This hierarchy emphasizes the strongest evidence that supports practice changes and clinical decision-making.

Clinical Practice Guidelines and Standards of Care

  • Clinical Practice Guidelines:

    • Evidence-based recommendations guiding the management of diseases, ensuring that interventions are standardized and effective.

  • Standards of Care:

    • These reflect the level of intervention that must be implemented when caring for clients, ensuring that nursing interventions are reliable, consistent, and of high quality.

    • Must be based on high levels of evidence and regularly updated to keep pace with advancements in medical research.

Conclusion

  • EBP is crucial for transforming nursing practices and significantly improving client outcomes.

  • It encourages critical thinking, persistent inquiry, and collaboration within nursing, thereby enhancing overall healthcare delivery and patient safety.
