Evidence-based practice (EBP) integrates the best clinical evidence, patient values, and clinician expertise to improve healthcare outcomes. Key components of EBP include research evidence, clinical expertise, and patient preferences, with structured steps to formulate questions, collect, and appraise evidence for practical application. The role of nurses in EBP emphasizes decision-making, knowledge transfer, resource management, and fostering an environment conducive to research and collaboration.

1. Evidence Based
Practice

2. INTRODUCTION
Evidence-based practice (EBP) is a problem-solving approach to the
delivery of health care that integrates the best evidence from
studies and patient care data with clinician expertise and patient
preferences and values. (Fineout-Overholt E, 2010)
.
EBP is the integration of clinical expertise, patient values, and the
best research evidence into the decision making process for
patient care
.
Clinical expertise refers to the clinician’s cumulated experience,
education and clinical skills
.
The patient brings to the encounter his or her own personal
preferences and unique concerns, expectations, and values
.

3. Health care that is evidence-based and conducted in a
caring context leads to better clinical decisions and
patient outcomes. Gaining knowledge and skills in the
EBP process provides nurses and other clinicians the tools
needed to take ownership of their practices and
transform health care
.

4. KEY COMPONENTS OF EBP
A. Research evidence
.
B. Clinical expertise, judicious use
.
C. Patient values and circumstances
.

6. EBP NURSING
Evidence Based Nursing: “An integration of the
best evidence available, nursing expertise, and the
values and preferences of the individuals, families,
and communities who are served
.

7. AIMS OF EVIDENCE BASED
PRACTICE
To provide the high quality and most cost-efficient nursing care
possible
.
To advance quality of care provided by nurses
.
To increase satisfaction among patients
.
To focus on nursing practice away from habits and tradition to
evidence and research
.
It results in better patient outcomes
.
It contributes to the science of nursing
.
It keeps practices current and relevant
.
It increases confidence in decision-making
.

8. FEATURES of EBP
Problem based and within the scope of the practitioners experience
.
It brings together the best available evidence and current practice by
combining research with knowledge and theory. So it narrows the
research practice gap. It facilitates application of research into
practice by including both primary and secondary research findings
.
It concerned with quality of service and is therefore a Quality assurance
activity
.
EBP projects are team projects and therefore require team support and
collaborative action
.
It support research projects and outcomes that are cost effective EBP
de-emphasizes ritual, isolated and unsystematic clinical experiences
ungrounded opinions and tradition as a basis of practice. It stresses
the use of research findings
.

9. WHY IS EBP RELEVANT TO
THE NURSING PRACTICE
?
There is a gap between what we know and what
we do. Nursing practice can and must be
changed from tradition-based to science-
based
:
Research-practice gap: Much of what is known
from research has not been applied in
practice. This is known as Research-Practice
Gap
.

10. STEPS OF EBP

11. STEPS OF EVIDENCE BASED
PRACTICE
Step 1: formulating a well built question
Step 2: collecting the most relevant and best
evidence to answer the clinical question
including searching for systematic
reviews/identifying articles
Step 3: Critically appraising the evidence that has
been collected for its validity, relevance and
applicability
.

12. Step 4: integrating the evidence with ones
clinical expertise, assessment of patient’s
condition and available health care
resources along with the patients
preferences and values to implement the
evidence
.
Step 5: Evaluating the change resulting from
application of evidence in practice.
Determine the areas for improvement
.

13. Step1: FORMULATING THE
QUESTION
With clinical areas ,there is often a barrage of details to
digest. a well built question includes the following
components
the patients disorder or disease
the intervention or finding under review
a comparison intervention
the question should be in PICOT or PICO format

14. PICOT FORMAT
Patient, Population or Problem
What are the characteristics of the patient or population
?
What is the condition or disease you are interested in
?
(
i.e. age, gender, ethnicity, with a certain disorder
)
Intervention or exposure
What do you want to do with this patient (e.g. treat, diagnose, observe)
?
(
exposure to a disease, risk behavior, prognostic factor
)
Comparison
What is the alternative to the intervention (e.g. placebo, different drug,
surgery)
?
(
could be a placebo or "business as usual" as in no disease, absence of
risk factor, Prognostic factor B
)

15. Outcome
What are the relevant outcomes (e.g.
morbidity, death, complications, risk of
disease, accuracy of a diagnosis, rate
of occurrence of adverse outcome)
Time
What time it takes to demonstrate an
outcome (e.g. the time it takes for the
intervention to achieve an outcome or
how long participants are observed)
.

16. Are insulin pumps more effective than
conventional therapies in managing type 2
diabetes in pregnant women
?
Patient/Population - Pregnant women with type
2 diabetes
Intervention - Insulin pump therapy
Comparison - Conventional insulin therapy
Outcome - Improved management of glucose
levels

17. SEARCH STRATEGIES BACKGROUND
INFORMATION
Background information may be found in sources such as
:
reference book entries
textbooks, chapters, appendices
drug monographs, guides to diagnostic tests
the library’s Bobcat catalog
selected electronic Reference Tools for Background
information in the health science
.

18. Clinical Evidence
.
Clinical Evidence describes the best available
evidence from systematic reviews, RCTs, and
observational studies when appropriate for
assessing the benefits and harms of treatments
.
Dynamed
.
Dynamed is a point-of-care reference resource
designed to provide clinicians with current,
evidence-based information to support clinical
decision-making
.
Essential Evidence
.
Essential Evidence is a one-stop reference that
includes evidence-based answers to clinical
questions concerning symptoms, diseases, and
treatment
.

19. FPIN Clinical Inquiries
.
Clinical Inquiries provides answers to clinical
questions by using a structured search,
critical appraisal, clinical perspective, and
rigorous peer review. FPIN Clinical Inquiries
deliver evidence for point of care use
.
UpToDate
.
UpToDate is an evidence-based, peer
reviewed information resource available via
the Web, desktop/laptop computer, and
PDA/mobile device
.

20. Step 4. APPLYING THE EVIDENCE/INTEGRATING EVIDENCE
WITH ONES CLINICAL
EXPERTISE
If the implementation criteria are met the team can design and
plot the innovation. To reach your conclusion you may
consult questions related to diagnosis ,therapy, harm and
prognosis keep in mind that you must interpret the
information based on a number of criteria and depending on
your skill and experience ,you may need to confer with a
peer
.
example- Sample evidence practice e.g. consider a nine
year old girl present in the ER with abdominal pain and
you suspect appendicitis. which imaging modality is
best for making the diagnosis CT or ultrasound
.

21. Step 5. EVALUATING THE CHANGE
The fifth step of the process, outcome evaluation, attempts
to interpret the results and evaluate the outcomes of the
applied evidence (intervention). Outcome measures
may be psychosocial (quality of life, improved patient
perception of care, reduction in depressive and anxiety
symptoms), physiologic
(
improved health, reduced complications
,)
or functional
improvement. Evaluation of the process and the results
may occur through peer assessment, audit, or even self
reflection. Depending on the type of outcomes
achieved, it may be possible to compare the outcomes
of a study with similar outcomes on a local, regional,
national, or international level
.

22. NURSE ROLE IN EVIDENCE-
BASED PRACTICE

)
As a scientist: A nurse ensures his or her practice is evidence-
based and that institution approved protocols are utilized
.
