Evidence-based practice

Evidence-Based Practice (EBP)

A problem-solving approach to clinical practice that combines the best evidence, clinical expertise, patient preferences and values, and available health care resources.

Purpose of EBP

To improve patient outcomes, safety, quality of care, and clinical decision-making.

Four main components of EBP

Best evidence, clinical expertise, patient preferences and values, and available health care resources.

Importance of EBP in nursing

It helps nurses make safe, effective, and informed clinical decisions.

Clinical judgment

Using nursing knowledge, evidence, and patient information to make decisions about patient care.

Seven steps of EBP

0. Cultivate inquiry, 1. Ask PICOT question, 2. Search evidence, 3. Critically appraise, 4. Integrate evidence, 5. Evaluate outcomes, 6. Communicate outcomes.

First step of EBP (Step 0)

Cultivate a spirit of inquiry.

Spirit of inquiry

Continuously questioning current practices and looking for better ways to provide care.

Problem-focused trigger

A clinical problem or trend identified during patient care.

Knowledge-focused trigger

A question arising from new information or research.

What does PICOT stand for?

Patient/Population, Intervention, Comparison, Outcome, Time.

P in PICOT

Patient population of interest.

I in PICOT

Intervention or area of interest.

C in PICOT

Comparison intervention or area of interest.

O in PICOT

Outcome.

T in PICOT

Time.

Use of PICOT questions by nurses

To develop specific clinical questions and find relevant research evidence.

Background question

A general question about a clinical issue.

Foreground question

A specific clinical question that can be answered using research evidence.

Critical appraisal

Carefully evaluating evidence for its quality, validity, reliability, and usefulness.

Highest level of evidence

Level I: Systematic reviews or meta-analyses of randomized controlled trials and guidelines based on systematic reviews.

Lowest level of evidence

Level VII: Expert opinions and reports of expert committees.

Systematic review

A structured review that summarizes evidence from multiple studies.

Meta-analysis

A review that uses statistical methods to combine results from multiple studies.

Randomized controlled trial (RCT)

An experimental study in which participants are randomly assigned to treatment or control groups.

Nursing research

A systematic process used to develop new knowledge that improves nursing practice.

Scientific method

A systematic approach to investigating questions and solving problems using observations and evidence.

Six steps of the research process

Identify the problem, Review literature, Develop the research question and study design, Collect data, Analyze data, Share findings.

Hypothesis

A prediction about the relationship between variables that can be tested through research.

Variable in research

A characteristic or factor that can change or be measured.

Quantitative research

Research that uses numerical data and statistical analysis.

Qualitative research

Research that explores people's experiences, perceptions, and meanings.

Reliability

The consistency of a measurement or research instrument.

Validity

The degree to which a tool or study measures what it is intended to measure.

Bias

An influence that can distort research findings or conclusions.

Generalizability

The ability to apply research findings to populations or settings beyond the study.

Informed consent in research

Voluntary agreement to participate after receiving information about the study, risks, and benefits.

Confidentiality in research

Protecting participants' private information from unauthorized disclosure.

Institutional Review Board (IRB)

A committee that reviews research involving human subjects to protect their rights and safety.

Translation research

Research that tests strategies for implementing evidence-based practices in real-world settings.

Performance improvement (PI)

A process used to improve health care practices, efficiency, safety, and patient outcomes.

Difference between EBP, research, and PI

EBP applies existing evidence; research generates new knowledge; PI improves local care processes.

PDSA stands for

Plan, Do, Study, Act.

Sentinel event

A patient safety event involving death, permanent harm, or severe temporary harm that requires immediate investigation.

Root cause analysis (RCA)

A structured method used to identify underlying causes of serious adverse events.

Active error

An unsafe action or mistake made by personnel directly involved in care.

Latent error

A hidden problem in an organization's systems or processes that contributes to errors.

Just culture

A safety culture that encourages error reporting and examines system problems rather than focusing only on individual blame.
