Evidence based medicine is the conscientious, explicit, and judicious use of current best evidence in making decisions about the care of individual patients. The practice of evidence based medicine means integrating individual clinical expertise with the best available external clinical evidence from systematic research.
Clinical Practice Guidelines are systematically developed statements of appropriate care designed to assist the practitioner and patient make decisions about appropriate health care for specific clinical circumstances.
A Systematic Review is a literature review focused on a single question which tries to identify, appraise, select and synthesis all high quality research evidence relevant to that question. Reviews are considered a Secondary Source in nursing.
Meta-analyses are systematic reviews that combine the results of several studies using quantitative statistics.
Research articles are published results of research studies and considered a Primary Source in nursing.
Because it is difficult for a clinician to analyze all the information in a field, resources such as UpToDate and Clinical Evidence offer summaries of evidence-based information on a topic.
