EVIDENCE-BASED NURSING RESEARCH
Definition
Importance
Utilization
Intended Learning Outcomes
Define evidence-based practice
Identify and enumerate the importance of
conducting evidence-based practice
researches
Determine the purpose and usefulness of
evidence-based research to nursing profession
Evidence-based Practice
DEFINITION
the conscientious, explicit and judicious use of
current best evidence in making decisions
about the care of the individual patient.
(Sackett D, 1996)
It means integrating individual clinical expertise
with the best available external clinical
evidence from systematic research.
Model of Evidence-based Practice
Best Research Evidence
Empirical knowledge generated from the
synthesis of quality study findings to address a
practice problem.
Clinical Expertise
Knowledge and skills of the healthcare professional providing
care.
Depends of his/her clinical experience, current knowledge of
the research and clinical literature and educational
preparation.
Patient Needs and Values
NEEDS VALUES
- Health promotion - Unique
- Illness prevention preferences
- Acute or chronic - Expectations
illness - Concerns
management - Cultural beliefs
- Rehabilitation
Presentation of EBP output
Purposes of Research in Implementing
an Evidence-Based Nursing Practice
Description
Explanation
Prediction
Control
Description
Identifying and understanding the nature of nursing
phenomena and, sometimes, the relationships among
them (Chinn & Kramer, 2008)
Through research, nurses are able to:
Describe what exists in nursing practice
Discover new information
Promote understanding of situations
Classify information for use in the discipline
Explanation
Clarifies the relationships among phenomena and
identifies the reasons why certain events occur.
Types of evidence essential for practice
Determination of the assessment data that need to be
gathered to address a patient’s health need.
The link of assessment data to a diagnosis.
The link of causative risk factors or etiologies to illness,
morbidity, and mortality.
Determination of the relationships among health risks,
health behaviors, and health status.
Prediction
Estimate the probability of a specific outcome in a given situation.
Through prediction the risk of illness is identified and linked to
possible screening methods to identify the illness.
Knowledge generated from research focused on prediction is
critical for EBP and includes the following:
Prediction of the risk for a disease in different populations
Prediction of behaviors that promote health and prevent illness
Prediction of the health care required based on a patient’s need
and values
Control
The ability to write a prescription to produce the desired
results.
Using the best research evidence, nurses could
prescribe specific interventions to meet the needs of
patients and their families (Brown, 20019; Craig, et.al.,
2007)
Introduction
to Quantitative and Qualitative Research
Generates different kinds of knowledge that are useful in
nursing practice.
Similarities:
Both require research expertise
involve rigor in implementation
generate scientific knowledge for nursing practice
Quantitative Research
Formal, objective, systematic process in which numerical
data are used to obtain information about the
world.
Derived from logical positivism – strict rules of logic, truth, laws and
predictions.
“Truth” is absolute
Researcher must be objective.
Qualitative Research
Systematic, subjective approach used to describe life
experiences and situations and give them meaning.
Interpretative, humanistic, and naturalistic
Concerned in understanding the meaning of social
interactions by those involved.
“Truth” is both complex and dynamic
