Enfermería Basada en la Evidencia

Introduction and Background

In this section, the presenters introduce themselves and provide an overview of the topic of evidence-based nursing. They discuss the importance of evidence-based practice in healthcare decision-making.

Introduction to Evidence-Based Nursing

• Consuelo and Catalina introduce themselves as teaching assistants from the Department of Nursing.

• They explain that this video will cover the concept of evidence-based nursing (EBN) and its history and evolution.

Importance of Evidence-Based Practice

This section highlights a scenario where healthcare professionals need to make decisions based on available evidence. It discusses the potential risks associated with traditional practices and introduces evidence-based practice as a solution.

Traditional Practices vs. Evidence-Based Practice

• The example is given of using bed rails for fall prevention in hospitalized adults, which has been a common practice.

• New studies suggest that bed rails may actually increase the risk of falls, as patients may try to climb over them.

• The latest recommendations include keeping the patient's bed at a low height, using bed brakes, lowering lower bed rails unless contraindicated, and ensuring personal items are within reach.

• The conflict between traditional practices and new evidence highlights the need for evidence-based practice in nursing.

Shift towards Evidence-Based Nursing

This section explains how evidence-based nursing changes the way care is provided by seeking answers through research, considering current best evidence, clinical judgment, patient preferences, and available resources.

Transition to Evidence-Based Nursing

• Many healthcare professionals base their decisions on personal experiences or opinions from other professionals.

• Evidence-based nursing aims to find better answers to uncertainties through research.

• The three pillars of EBN are:

• Current best available evidence

• Clinical expertise

• Patient preferences and values

• Resources, both material and human, also play a role in evidence-based nursing.

Definition of Evidence-Based Nursing

This section provides a definition of evidence-based nursing and emphasizes the importance of incorporating research evidence into decision-making for patient care.

Definition of Evidence-Based Nursing

• Evidence-based nursing is the conscious, explicit, and judicious application of the best available scientific evidence to guide nursing practice decisions.

• It involves considering patient preferences and values while incorporating professional expertise.

• The goal is to provide high-quality care based on the most up-to-date evidence.

History and Evolution of Evidence-Based Practice

This section explores the history of evidence-based practice, starting with criticisms towards medical decision-making without considering research outcomes. It then introduces the concept of medicine based on evidence (MBE) and its subsequent development into practice based on evidence (PBE).

History of Evidence-Based Practice

• In 1972, Dr. Archie Cochrane criticized healthcare professionals for not considering research outcomes in clinical practice.

• In 1991, the concept of medicine based on evidence (MBE) was introduced as the conscious, explicit, and judicious use of current best evidence in making decisions about individual patient care.

• The popularity of MBE led to its expansion into other healthcare professions as practice based on evidence (PBE).

• Conferences and publications focused on EBP started emerging in the late 1990s.

Phases of Evidence-Based Practice

This section outlines the phases involved in practicing evidence-based nursing. It covers formulating clinical questions, conducting literature searches, critically appraising findings, implementing results into practice, and evaluating the outcomes.

Phases of Evidence-Based Practice

• Formulating a clinical question: Structured and specific questions are developed to address identified problems in nursing practice.

• Conducting a literature search: Relevant literature is identified to answer the clinical question.

• Critically appraising the literature: The selected literature is evaluated for its quality and relevance.

• Implementing the results: Findings from the literature are applied to nursing practice.

• Evaluating the outcomes: The impact of implementing evidence-based changes is assessed.

Formulating Clinical Questions

This section focuses on formulating structured and specific clinical questions that guide evidence-based nursing practice. It introduces the PICO framework for constructing well-defined questions.

Formulating Clinical Questions

• Well-constructed clinical questions should include essential elements:

• P (Problem or Population): Describing a group of patients similar to the one being treated.

• I (Intervention): Identifying the intervention being considered.

• C (Comparison): Comparing different interventions or approaches.

• O (Outcome): Determining what outcomes are being measured or evaluated.

Literature Search Strategies

This section discusses strategies for conducting effective literature searches in evidence-based nursing. It emphasizes accessing reliable sources of information and developing skills in search techniques.

Literature Search Strategies

• Accessible sources of information and search strategies are crucial for finding relevant literature.

• Skills in using search strategies and balancing sensitivity (finding all relevant articles) with specificity (excluding irrelevant articles) are important.

• A balance between sensitivity and specificity ensures that research findings align with clinical questions.

These notes provide an overview of each section covered in the transcript, highlighting key points discussed by the presenters.

Free Graphics and Nursing School Partnership

The nursing school has a partnership with the Registered Nurses Association (RNA) to enhance the quality of care through evidence-based knowledge.

Utilization of Best Practice Guidelines (BPG)

• BPG are systematically developed documents that assist nurses and patients in making appropriate healthcare decisions.

• These guidelines provide recommendations categorized by the level of evidence, ensuring reliable information is used in the curriculum.

Critical Reading for Quality Analysis

• Critical reading involves a systematic process to evaluate study design, methodology, data quality, and result interpretation.

• Different criteria exist for evaluating quantitative and qualitative studies.

• Three key questions help assess the validity, significance, and relevance of research results for clinical practice.

Evaluation Tools for Research Studies

• Various instruments guide the analysis of different types of studies.

• CASP (Critical Appraisal Skills Programme) is an instrument used to evaluate both qualitative and quantitative research.

• Other tools like ESTRO provide guidelines specifically for evaluating quantitative studies.

Implementing Evidence-Based Practice

After analyzing valid research results, implementing changes in practice requires identifying barriers, potential causes of failure, and utilizing effective strategies.

Implementation Tools

• Clinical practice guidelines and frameworks support the implementation process.

• Evaluation is crucial to assess the impact of changes based on evidence-based practice. It helps identify benefits, harms, costs, and outcomes.

Benefits of Evidence-Based Nursing Practice

Evidence-based nursing practice offers numerous advantages:

1. Improved care quality and organization

2. Increased patient safety

3. Enhanced teamwork effectiveness

Limitations in Implementing Evidence-Based Nursing

Several challenges hinder the implementation of evidence-based nursing, including resistance to change, lack of understanding, and limited access to research.

Limitations in Practice

• Some barriers include nurses' reluctance to read research reports and change clinical practice.

• Lack of comprehension or belief in research results.

• Limited knowledge on how to utilize research findings effectively.

• Restrictions on applying certain research findings due to external factors.

Importance of Evidence-Based Nursing

The goal of nursing research is to generate new knowledge that contributes to evidence-based care. This leads to improved outcomes for patients, families, caregivers, and healthcare services.
