Evidence-Based Practice and Nursing Research

Fundamentals of Nursing: Evidence-Based Practice and Nursing Research

Chapter Overview

The chapter focuses on Evidence-Based Practice (EBP) and Nursing Research, highlighting its significance in improving clinical practices and patient outcomes. The text outlines various research methodologies, components of research, the historical context of EBP, and practical application in nursing.

LO 13.1 Nursing Research

Definition of Research

  • Research: A systematic investigation aimed at validating or refining existing knowledge or generating new knowledge.
  • Nursing Research: Encompasses various aspects:
    • Basic Research: Focuses on generating theories.
    • Applied Research: Tests these theories in diverse situations with various populations.
    • Clinical Research: Evaluates the effectiveness of interventions.

American Nurses Association Research Standards

  • Guiding Evidence-Based Practice: Utilizes the best available evidence to inform decision-making in practice.
  • Research Participation: Encourages nurses to engage in relevant research activities to bolster evidence utilization.

LO 13.2 Methods of Research

Research Methodologies

Three primary research methods are used in studies:

  1. Quantitative Research
    • Deductive Approach: Begins with a theory that is tested through data collection.
    • Descriptive: Aims to describe characteristics without manipulating variables.
    • Correlational: Examines relationships between two or more variables.
    • Experimental: Involves manipulation of variables to ascertain effects on outcomes.
    • Quasi-experimental: Studies without randomization, providing less rigorous controls.
  2. Qualitative Research
    • Phenomenological: Explores lived experiences of individuals.
    • Grounded Theory: Develops theories based on data collected from participants.
    • Ethnography: Studies cultures and communities from an insider perspective.
    • Historical: Investigates past events and their implications.
  3. Combined Methods: Utilizes both qualitative and quantitative methods to enrich data findings.

Data Definition

  • Data: Facts collected and analyzed by researchers, represented as either numbers (quantitative) or words (qualitative).

LO 13.3 Components of Research

Key Components

  • Literature Review: An integration and examination of previous studies, which can be:
    • Integrative: Synthesizes different studies for a comprehensive view.
    • Systematic: Follows a structured methodology in reviewing literature.
    • Meta-analysis: Combines statistical data from multiple studies for higher validity.
  • Data Collection: Involves utilizing various instruments to gather necessary information.

Variables

  • Independent Variables: Factors manipulated in research to observe effects.
  • Dependent Variables: Outcomes measured to see the impact of independent variables.
  • Control Group: A group that does not receive the treatment, serving as a baseline comparison.

Ethical Considerations

  • Institutional Review Board (IRB): Ensures the protection of human subjects involved in research.
  • Informed Consent: Process starts with recruitment and continues throughout the study, ensuring participants understand the research implications.
  • Confidentiality and Anonymity: Protecting subjects' identities as per the Health Insurance Portability and Accountability Act (HIPAA).

Data Analysis Techniques

  • Procedures implemented to summarize and interpret data effectively, ensuring results are meaningful.

Dissemination of Outcomes

  • Communication: Sharing findings through publications, workshops, or presentations.
  • Application to Practice: Translating research findings into practice with an emphasis on patient education about the results.

LO 13.4 Evidence-Based Practice (EBP)

Historical Context

Notable figures impacting EBP include:

  • Florence Nightingale: Pioneer of nursing practices based on evidence.
  • Cochrane: Advocate for systematic reviews in healthcare.

Definitions

  • Research Utilization: Implementation of research findings to enhance clinical practices.
  • Evidence-Based Practice (EBP): Combines theoretical knowledge, clinical judgment, and patient preferences to guide nursing decisions.

Barriers to EBP

  • Challenges in conveying how to effectively conduct EBP.
  • Individual skill levels in assessing research quality.
  • Associated costs.
  • Overabundance of available research to review.

LO 13.5 Conducting Evidence-Based Research

Steps in Conducting Research

  1. Assessing the Problem: Identifying the issue to be addressed.
  2. Developing a Question: Utilizing the PICO(T) framework:
    • Population/Patient Problem
    • Intervention
    • Comparison
    • Outcome
    • Timeframe
  3. Searching for Evidence: Finding relevant information:
    • General information resources (background).
    • Filtered resources (e.g., systematic reviews).
    • Unfiltered resources (e.g., original research articles).
  4. Critically Appraising Information: Assessing:
    • Internal validity: How well the study was conducted.
    • Result analysis: Understanding outcomes obtained and their implications.
    • External validity: Applicability of findings to wider populations.
  5. Synthesizing Evidence and Developing Plans: Integrating findings to form actionable strategies.
  6. Implementing the Plan: Putting the strategies into practice for real-world application.
  7. Maintaining Change and Re-evaluating: Ongoing assessment of strategies to ensure continued efficacy.

Evidence Levels

  • Level I: Systematic review or meta-analysis of randomized controlled trials (RCTs); Evidence-based clinical practice guidelines derived from systematic reviews.
  • Level II: A well-designed randomized controlled trial.
  • Level III: Controlled trials lacking randomization (quasiexperimental studies).
  • Level IV: Single non-experimental studies (e.g., case-control, correlational, cohort).
  • Level V: Systematic reviews of descriptive and qualitative studies.
  • Level VI: Single descriptive or qualitative studies.
  • Level VII: Opinions of authorities or expert committee reports.

LO 13.6 Implementing Research in Nursing Practice

  • Recognizing varying types of evidence levels.
  • Evaluating research findings for strength and relevance.
  • Understanding evidence types that address patient preferences.
  • Utilizing critical thinking to apply nursing practices in alignment with patient values.
  • Collaboration with colleagues to facilitate best practice implementations in patient care.

LO 13.7 Magnet Hospital Status and the Role of Nursing Research in Practice

Magnet Recognition

  • American Nurses’ Credentialing Center (ANCC): Governing body administering the Magnet Hospital Recognition program.
  • Criteria for Magnet Recognition: Hospitals must meet specific criteria assessing the quality and strength of nursing practices.

Research and Best Practices

  • Inclusion of patient perspectives in care planning to tailor approaches.
  • Emphasis on evidence-based practices over traditional methods in clinical settings.
