What is Evidence-Based Nursing?

  • Evidence-Based Nursing is an ongoing process that includes:

    • Critical evaluation of evidence, nursing theory, and clinical expertise alongside patient involvement.

    • Aim is to deliver optimum nursing care tailored to the individual.

  • Importance of Evidence-Based Practices:

    • Understanding benefits enhances nursing practice.

    • Incorporating new evidence improves patient interactions.

    • Advancing nursing knowledge aids professional growth.

Why Do We Need Evidence-Based Practice (EBP)?

  • Benefits of Evidence-Based Nursing Care:

    • Improves quality of care and safety for patients.

    • Increases satisfaction among nursing staff.

    • Reduces healthcare costs.

  • Attributes of Good Evidence:

    • Replicability: Evidence can be reproduced.

    • Reliability: Evidence consistently yields similar results.

    • Validity: Evidence measures what it claims to measure.

    • Generalizability: Evidence applies to broader populations.

Where Do We Find Evidence-Based Practice?

  • Sources of Evidence:

    • Textbooks.

    • Research articles.

    • Quality improvement projects.

    • Standards of care.

    • Chart reviews.

    • Clinical projects.

Types of Evidence

  • Quantitative Research

  • Qualitative Research

  • Mixed Methods

  • Primary Evidence: Original studies.

    • Serves as foundation for secondary literature.

  • Secondary Evidence: Summaries, systematic reviews, meta-analyses, and practice guidelines built upon primary evidence.

Steps for Evidence-Based Practice

  1. Ask an answerable PICOT question.

  2. Search the literature.

  3. Evaluate the literature.

  4. Integrate the evidence and apply it to a clinical setting.

  5. Evaluate the outcomes.

  6. Share your findings with others.

Developing a PICOT Question

  • PICOT Framework:

    • P: Population of interest.

    • I: Intervention of interest.

    • C: Comparison to another intervention or group.

    • O: Desired outcome.

    • T: Timeframe for the study.

  • Example of a PICOT Question:

    • Do pediatric patients (P) who play sports (I) compared to those who play instruments (C) have fewer absences due to illness (O) during elementary school (T)?

Rights of Participants

  • Institutional Review Board (IRB): Oversees ethical practices in research.

  • Informed Consent: Ensures participants are aware and understand:

    • Purpose and methods of the study.

    • Their right to choose participation.

    • How their confidentiality will be maintained.
