Objective 3. Describe EBP and it's development
and why it is important for nursing practice.
Why is research important for nursing practice?
As nurses we are accountable to our patients and their families for
providing the highest quality, most cost-effective care possible. This
requires that we constantly evaluate and improve our care based on new
and credible knowledge. Research-based scientific knowledge can be used
to improve nursing care, patient outcomes, and how we deliver care. In
other words, research provides evidence on which to base our nursing
care, or EBP.
How is evidence-based practice developed?
EBP is developed through a combination of research approaches. Through
qualitative research we are able to better understand the patient's and
family's experiences with health and illness. Quantitative research
provides a mechanism for testing the effectiveness of nursing
interventions. Finally, outcomes research focuses on the provision of
quality, cost-effective care.
What types of research are used in developing EBP?
There are four types of research. Each type of research provides the
basis for the next level of inquiry.
- Description - Through descriptive research we
try to identify and better understand nursing phenomena and the
relationships among the phenomena. Descriptive research provides the
groundwork for further studies that seek to explain, predict, or
control nursing phenomena.
- Explanation -
Explanation clarifies the relationship among phenomena and identifies
why certain events occur. An example of this is the research that has
been done to examine the relationship between nosocomial infections,
higher levels of morbidity and mortality, and higher hospital costs.
- This examines the probability of an outcome occurring in specific
situations. This type of research is common in epidemiology in which
specified risk factors predict the occurrence of disease. For example,
obesity and inactivity predict higher rates of heart disease.
- Control is the ability to specify how to produce a desired outcome.
Control is dependent on prediction. For example, the incidence of heart
disease is reduced when levels of obesity and inactivity are controlled
or when people are a normal weight and they exercise.
Objective 4: Identify your role in research as a
What are nurses' roles in the research process?
According to professional nursing organizations, such as the American
Nurses Association, the level of research involvement increases with
each successive level of advanced educational preparation. However,
having BSN preparation does not preclude being able to participate in
higher levels of research.
Match the research involvement with the educational preparation level
of BSN, MSN, or PhD.
