Evidence-Based Clinical Practice Guidelines

Evidence-Based Clinical Practice Guidelines are based on a systematic review of published studies. Multidisciplinary guideline development groups construct Evidence-Based Clinical Practice Guidelines to serve as an educational tool based on an assessment of the current published scientific and clinical information and accepted approaches to treatment.
