Week: 14
Instructors: Stacey Hurrell DNP, RN, LSN, CNE and Emily James DNP, APRN, PMHNP-BC
Learning Objectives
Explain the concept of Evidence-Based Practice (EBP) and describe its essential elements.
Define nursing research and differentiate between its two main categories: qualitative and quantitative.
Identify at least three reliable sources to obtain evidence-based information.
Discuss the use of evidence-based practice to guide the delivery of nursing care.
Why Do We Do What We Do?
Introduction to the significance of understanding EBP in nursing.
Evidence-Based Practice (EBP)
Definition: A problem-solving approach to client care incorporating:
- The most accurate scientific evidence.
- Clinical expertise.
- Client values.Process:
- Evidence is utilized as the foundation for practice recommendations.
- Implementations occur followed by evaluations.Inspiration:
- Aimed at providing optimal care for patients and families.
- Often necessitated by the need for system-wide changes.
The Spirit of Inquiry
Definition:
- A desire to acquire knowledge and skills to deliver the best care.Characteristics:
- Curiosity and awareness of healthcare practices.
- Ability to entertain change, rather than rely solely on tradition or past experiences.
Essential Elements of Evidence-Based Practice
Identify a Problem:
- Formulate a question based on observed practice issues.Search for Credible Sources:
- Seek factual and reliable information.Evaluate Findings:
- Critically review the information obtained.Implement Recommendations:
- Change interventions based on findings.Review Effectiveness:
- Assess whether the new interventions yield improved results.Disseminate Results:
- Share findings with peers to inform broader practices.Goal:
- Use this process to address patient care or workplace issues.
Identify the Problem: Think, Pair, Share
Activity:
- Collaborate with a classmate to discuss a workplace issue that may be systemic in nature.
PICOT Question
Definition: A structured way to formulate research questions.
Components:
- Population: The focus group for the investigation.
- Intervention: The specific treatment or action performed by the nurse.
- Comparison: Current intervention or an alternative.
- Outcome: The anticipated results of the intervention.
- Time: Duration of the study (if relevant).Example PICOT Question:
- In sophomore nursing students, does participation in pre-exam meditation, compared to no meditation, improve test anxiety over a semester?
Finding Credible Evidence
Sources to Consider:
- Textbooks.
- Research findings from articles.
- Articles with practice recommendations.
- Credible websites.
- Reports from governmental agencies and non-profit organizations.
- Conducting a literature search using library databases like CINAHL, PubMed, Ovid Medline, etc.
- Pay attention to the search words based on PICOT components.
- Evaluate that information is current (generally within the last 5 years).
- Prefer articles that are ‘scholarly’ and ‘peer-reviewed’.
- Consider using a literature matrix to assess findings.
Implement Your Intervention
Key Considerations:
- Involve stakeholders in the process.
- Determine if a theoretical framework guides the process.
- Assess feasibility in terms of time, cost, effort, and staffing.Example Intervention:
- Adding meditation sessions 30 minutes before examinations to reduce anxiety.
Evaluate Effectiveness
Evaluation Questions:
- Did your intervention lead to significant differences in outcomes?
- How will you measure these outcomes?
- Possible methods include pre- and post-intervention surveys or data collection instruments.
- Were there any limitations or concerns noted during the evaluation?
- Would you make modifications to the intervention based on your findings?
- Would you conduct the intervention again?
Disseminating Results
Final Step in EBP Process:
- Share findings and insights with relevant stakeholders.Communication Methods:
- Presentations.
- Posters.
- Publications in journals.
- Conferences.
Nursing Research
Purpose:
- To generate new knowledge aimed at advancing solutions for healthcare problems.
- Enhances practice and may prompt further research questions.Development of Evidence:
- Nursing research is focused on creating new knowledge, while quality improvement focuses on analyzing existing evidence for application.Guiding the Research Process Using the Nursing Process:
1. Assessment: Identify the problem.
2. Analysis: Formulate the research question.
3. Planning: Design the research methodology.
4. Implementation: Recruit participants and gather data.
5. Evaluation: Analyze and disseminate results.
Types of Research
Quantitative Research:
- Utilizes numerical data for outcome evaluation.
- Involves counts or measures analyzed using statistical methods.
- Data is collected through observations or surveys.
- Involves a controlled experiment where one group receives an intervention, and another does not, allowing comparison of outcomes.
- Often tests a specific hypothesis.Qualitative Research:
- Aims to enhance understanding, describing, and exploring subjective issues in healthcare.
- Data tend to be narrative; exploring reasons, attitudes, and motivations.
- Researchers focus on understanding experiences from the participant's perspective.
- Typically uses smaller sample sizes and data is collected through interviews and dialogues.
Scholarly Database as Credible Evidence
Examples: CINAHL or PubMed
Functions:
- Provide access to a diverse range of research articles and academic resources.
- Published in peer-reviewed, professional journals promoting rigorous academic standards.Research Tips:
- Use relevant keywords and search terms to optimize results.
- Read abstracts to determine the relevance of articles.Abstract Definition:
- A brief summary of a study detailing its purpose, design, findings, and researcher.
Let’s Practice!
Activity Instructions:
- Access the St. Kate’s site and select “Library.”
- Navigate to ‘Databases’ and locate CINAHL Ultimate.
- Search for a topic of interest or a previously discussed problem by entering search terms.
- Assess the found sources for currency and authorship credentials.
Evaluating Websites for Credibility
Check Domain:
- Favor sites with “edu” or “gov” as they tend to provide credible information.
- “Org” domains typically offer factual data.
- Avoid “com” domains unless you confirm credibility since they suggest commercial interests.Author Credibility:
- Examine authors' qualifications and affiliations.
- Assess if the authors have expertise in the article's subject area.
- Determine the intended purpose of the website.
- Verify if the information is current and accurate.
Peer-Reviewed Journals
Characteristics:
- Contain articles subjected to review by professionals in similar fields to ensure scholarly quality.
- Undergo rigorous review processes, with authors making edits based on peer feedback before publication.
- Considered a reliable source of scholarly evidence.
- Access to many nursing journals available through library and database resources.
Applying Research to Nursing Practice
Clinical Practice Guidelines:
- Evidence-based recommendations for managing diseases and preventive care.Critical Pathways:
- Clinical tools that apply evidence-based guidelines to organize care delivery for treatment.
- Aim to standardize care, enhance client outcomes, and allow for individualization per client needs.Standards of Care:
- Represent typical interventions entered in care for specific conditions affecting clients.
