3. Evidence-based practice is the idea that
occupational practices ought to be based on
The movement towards evidence-based practices
attempts to encourage professionals and other
decision-makers to pay more attention to
evidence to inform their decision-making.
The goal of evidence-based practice is to
eliminate unsound or outdated practices in more
by shifting the basis for decision making from
tradition, intuition, and unsystematic experience to
firmly grounded scientific research.
4. Evidence based practice (EBP) is the conscientious use
of current best evidence in making decisions about
(Sackett, Straus, Richardson, Rosenberg,
& Haynes, 2000).
It is a problem solving approach to clinical practice
and administrative issues that integrates:
A systematic search for and critical appraisal of the
most relevant evidence to answer a burning clinical
One's own clinical expertise
Patient preferences and values
(Melnyk & Fineout-Overholt, 2014)
5. 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.
9. There are many examples of EBP in the daily
practice of nursing.
1. Infection Control
The last thing a patient wants when going to a
hospital for treatment is a hospital-acquired
infection. Nurses play a key role in helping to
prevent illness before it happens by adhering to
evidence-based infection-control policies.
This includes keeping the healthcare
environment clean, wearing personal protective
clothing, using barrier precautions and practicing
correct hand washing.
Although nurses are busy with many
responsibilities, the time it takes to control
infection is well worth the effort.
10. 2. Oxygen Use in Patients with COPD
For patient health and safety, it is essential that
nurses follow evidence-based practice in nursing
when it comes to giving oxygen to patients with
Despite the belief by some that providing oxygen
to these patients can create serious issues such
as hypercarbia, acidosis or even death, the
evidence-based protocol is to provide oxygen to
COPD patients. This practice can help prevent
hypoxia and organ failure. Giving oxygen, which
is the correct treatment based on the evidence,
can enhance COPD patients’ quality of life and
help them live longer.
11. 3. Measuring Blood Pressure Noninvasively in
Nurses should measure blood pressure
according to evidence-based practice
because accurate measurements are an
essential part of effective treatment.
Measuring blood pressure in children is a
different procedure than it is for adults.
Measuring children’s blood pressure involves
the auscultatory method, then comparing the
measurement against data gathered with the
12. 4. Intravenous Catheter Size and Blood
Nurses should follow EBP when using
intravenous catheters to administer blood for
packed red blood cell transfusions (PRBC).
The protocol indicates that nurses should use
a smaller-gauge catheter, which increases
from practice over

of the best evidence available, nursing
expertise, and the values and
preferences of the individuals, families,
and communities who are served.
17. To provide the high quality and most cost-efficient
nursing care possible.
To update knowledge & is essential for life long
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.
To better patient outcomes.
To provide clinical judgment

To increase confidence in decision-making.
18. Problem based and within the scope of the practitioners
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
EBP projects are team projects and therefore require team
support and collaborative action.
It support research projects and outcomes that are cost

19. 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
researchhas not been applied in practice. This is known as
21. 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
Step 3: Critically appraising the evidence that
has been collected for its validity, relevance
22. 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
Determine the areas for improvement.
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
24. 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)
What is the alternative to the intervention (e.g. placebo, different drug,
(could be a placebo or "business as usual" as in no disease, absence of
risk factor, Prognostic factor B )
What are the relevant outcomes (e.g. morbidity, death,
complications, risk of disease, accuracy of a diagnosis, rate of
occurrence of adverse outcome)
What time it takes to demonstrate an outcome (e.g. the timeit
takes for the intervention to achieve an outcome or how long
participants are observed).
26. Patient/Population - Pregnant women with
type 2 diabetes

Background information in the health science.
Once a clinical practice question has been selected,
the next step is to search and assemble research
evidence on the topic. In doing a literature review as a
background for a new study, the central goal is to
discover where the gap are and how best to advance
The resourses falls into 3 categories:
29. 1.General information/background resourses-
to collect the past information of a particular disease. e.g
measles has been nearly eradicated, but there has been a
fairly recent outbreak. If you need to refresh your knowledge
of the clinical presentation, diagnosis etc of measles, a
background resource would be the best place to start.
If you are trying to decide on a course of action for a patient
(diagnosis, treatment etc)and want to base your decision on the
best available evidence, consult a filtered resource. clinical
experts and subject specialists pose a question and then
synthesize evidence to state conclusions based on the
30. Unfiltered resources- If you don’t find an
appropriate answer in the filtered resourses ,you
will need to search unfiltered resourses (the primary
literature) to locate studies that answer your question.
unfiltered resourses provide the most recent
information ,but its upto to the clinician to evaluate
each study found to determine its validity and
applicability to the patient.
Effectvely searching and evaluating the studies
found in unfiltered resources takes more time and
skill, which is why filtered resources are the first
choice of answering clinical questions.
31. A. PRE-APPRAISED RESOURCES: Filtered resource

36. META-SEARCH ENGINES:
Trip: (Turning research in to practice)
The TRIP Database searches across
multiple internet sites for evidence-based
content. It covers key medical journals,
Cochrane Systematic reviews, clinical
quidelines, and other highly relevant websites
to help health professionals find high quality
clinical evidence for clinical practice.
The assessment of evidence by systematically
reviewing its relevance, validity and results of
In determining the implementation potential of an innovation
in a particular setting, several issues should be considered,
particularly the transferability of the innovation, the
feasibility of implementing it and its cost benefit ratio.
For example, the traditional method for verifying the
placement of a nasogastric tube was air insufflation.
However, according to current nursing research, the
accurate method for verifying placement is radiologic
examination (Metheny & Titler, 2001).
38. If the implementation assessment suggests that there might
be problems in testing the innovation in that particular
practice setting, then the team can either identify a new
problem and begin the process a new or consider adopting
the plan to improve the implementation potential (e.g.
seeking external resources if cost were the inhibiting factors)
39. 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.
40. 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
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.
43. The stelter model was designed with the
assumption that Research Utilization could be
not only by organizations but by individual
clinicians and managers. It was a model
designed to promote and facilititate critical
thinking about the application of research
findings in practice.
The current model presented graphically
involves five sequential phases:
In this phase, the nursing officer define the underlying purpose and
outcomes of the project, search, sort and select sources of research
She considers external factors that can influence potential application
and internal factors that can diminish objectivity and affirm the priority
of perceived problem.
This phase involves a utilization of focused critique of each source of
evidence, focusing in particular on whether it is sufficiently sound for
potential application in practice.
Comparative evaluation and decision- making
This phase involves a synthesis of findings and application of criteria
that taken together are used to determine the desirability and
feasibility of applying findings from validated source to nursing
practice. The end result of the comparative evaluation is to make a
decision about using the study findings.
This phase involves activities to confirm how the
findings will be used (e.g. formally or informally)
and spell out the operational details of the
application and implement them.
In the final phase, the application is evaluated.
Informal use of the innovation versus formal
use would lead to different evaluative
47. Lowa model was developed at the university of
Lowa hospitals and clinics in 1990s to serve as a
guide for nurses to use research findings to improve
patient care /quality of care.
The model was developed as a pathway / method
to EBP – a method to guide the steps to help
identify issues, research solutions and implement
It is an application – oriented guide for the EBP
48. 1. Identify the trigger where an EBP change is
warranted. Either a knowledge focus
trigger or a problem focus trigger.
2. Determine if the problem at the hand is a
priority for the organization, practice,
department or unit.
3. Form a team that will develop, evaluate &
implement the EBP change. The team
should be made up of representative both
in and out of nursing unit. This helps in
better evaluation and implementation of
49. 4. Gather and analyze the research related to the
desired practice change. This includes
formulating a good research question using the
PICO (T) method and conducting a literature
search looking for related research studies.
5. Critique and synthesize the research discovered
during the literature search. This includes
reviewing the research to determine if the
change is scientifically sound.
6. STOP & DECIDE if there is sufficient research to
implement a practice change:
No – review the research
Yes- move to step 7
50. 7. Implement change into Pilot program.
Change one or two smaller areas / units first
8. Evaluate results. Is the change feasible and
does it result in improved outcomes?
NO- Continue to evaluate the care and new
research to be able to revisit the issue in the
future with new information.
YES- introduce the change across the
department/ unit/ practice/ organization. After
the introduction of the change, continue to
observe, evaluate, and analyze the results.

nursing (CURN) project. The CURN project
was designed to develop and test a model for
using research- based knowledge in clinical
Research utilization is viewed as an
organizational process. Planned change is
integrated throughout the research
System change is essential to establishing
research based practice on a large scale.
55. The best evidence for interventions comes from
following a evidence hierarchy.
Randomized controlled trial
Case control study
Cross-section analytical study
58. Resistant to changes in nursing
I n ability to critically appraise
Time, workload pressures, and
Lack of continuing education
Fearof "stepping on one'stoes“
Poor administrative support.
60. Many Nurses have not received any formal
instruction in research and they lack skill to
judge the merits of a study.
Nurses attitude toward research and their motivation
to engage in EBP have been identified a potential
barrier. People are often resistant to change. Change
requires effort, retraining and restructuring of work
habits. Thus there is likely to be some opposition to
introducing innovations in practice setting.
Read widely and critically. Professionally
accountable nurses should read journals relating to
their specialty, including research reports in them.
61. Attend professional conference. Conference attending
give opportunities to meet researchers and to explore
Learn to expect evidence that a procedure is effective.
Nurses need to develop expectations that the decisions
they make in their clinical practice are based on sound
Become involved in a journal club. Many
organizations that employ nurses sponsor journal
clubs that meet to review research articles that have
potential relevance to practice.
Pursue and participate in EBP projects. Nurses who
are involved in research related activities develop
more positive attitudes toward research and better
62. Many of the major impediments to using research in practice
stem from the organizations that train and employ nurses.
Organizations have failed to motivate or reward nurses to seek
ways to implement appropriate findings in their practice. In
several studies of barriers to RU, one of the greatest
reported Barrier was “insufficient time on the job to implement new
ideas”. Organizations may be reluctant to expand resources for
RU, EBP activities or for changing organizational policy.
ADVICE: To promote the use of research evidence,
administrators can adopt the following strategies:
Foster a climate of intellectual curiosity. Open communication is
important in persuading staff nurses that their experiences and
problem are important and that the administration is willing to
consider innovative solutions.
63. Reward efforts for using research. RU should not
be the primary criterion for evaluating nurses
performance but its inclusion is an important
criteria to affect their behavior.
Seek opportunities for institutional RU/EBP projects.
Organizational efforts and commitment are
essential for the type of projects. ·
Offer emotional or moral support. Administrators
need to make their support visible by informing staff
by establishing EBP committees, by helping to
develop journal clubs and by serving as role models
for staff nurses.
Offer financial or research support for utilization.
64. There is a shortage of appropriate role
models- nurses who can be emulated for
their success in using or promoting the use
of research in clinical practice. The nurses
feel that he or she didn’t have “enough
authority to change patient careprocedures”
Educators could help to promote the use
of research evidence through the
65. Incorporate research findings into curriculum.
Research findings should be integrated
throughout the curriculum and when possible,
the efficacy of specific procedures should be
documented by referring to relevant studies.
Encouraging research and research use. Either
by acting as role models to students or by
demonstrating positive attitudes towards
research and its use in nursing.
Place demands on researchers. Faculty review
of research proposals should demand that
researchers demonstrate the proposed studies
potential for clinical use; they can also demand
that the researchers include a specific plan for
dissemination or utilization.
66. 1.A nurse can be a decision maker and coordinator of care.
2. As a scientist: A nurse ensures his or her practice is evidence-
based and that institution approved protocols are utilized.
3. As a transferor of knowledge: This important role is invoked
when discussing the plan of care with patients, their loved
ones, and with other members of the healthcare team.
4. Manage resources and facilitate the success of unit-based EBP
