Evidence based practice within biomedical science
establishes transparent, systematic review methods to evaluate quality
improvement practice effectiveness. It Improves healthcare quality and patient
outcomes by disseminating completed evidence reviews of practice effectiveness
used to identify evidence based laboratory medicine “best practices” as well
this it Increases engagement of laboratory professionals in quality improvement
research and data collection finally it Encourages recognition of laboratory
professionals as partners in healthcare policy and decision-making.
Evidence-based practice has done much to
advance healthcare, causing all methods of care to be based on the best
available credible evidence and to restrict the opinions of experts to be taken
only as opinions rather than proven facts.
