Discussion Question:
Explain the difference
between internal and external evidence. How can each of these types of evidence
be utilized for quality improvement in the clinical setting?
Your initial posting should be at
least 500 words in length and utilize at least two scholarly sources other than the textbook.(Evidence-Based
Practice in Nursing & Healthcare. A Guide to Best Practice. Third Edition
(Melnyk and Fineout-Overholt, 2015).
OVERVIEW
This module identifies sources of nursing and healthcare
knowledge and how to critically appraise knowledge for clinical decision
making. The strength of scientific evidence is emphasized as a means to
evaluate whether or not research is applicable for healthcare decision making.
Both internal and external evidence are defined. The application of internal
and external evidence for the implementation of evidence based practice and
quality improvement projects in the clinical setting is discussed.
Quantitative research is defined as a means of determining how
an intervention should be implemented. The critical appraisal of quantitative
research studies is discussed in detail. Evidence appraisal questions focus on
reliability, validity and applicability of the studies to clinical practice and
decision making. Specific appraisal questions related to case studies,
case-control studies, cohort studies, randomized control trials and systematic
review quantitative research designs are identified. Bias, confounding results,
effect size and confidence intervals are examined as issues influencing the
quality of quantitative studies.
GOALS
After completing this
module, students will be able to do the following:
- CLO 2: Describe the basic
concepts, techniques, and methodologies underlying the research process
and their application in the study of nursing problems. - CLO 4: Use information technology
to retrieve hierarchical levels of evidence that addresses clinical
questions - CLO 5: Utilize effective critical
thinking and written communication skills in the critique of research for
applicability to nursing practice.
