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.
