  3. EVIDENCE IN MEDICINE • research is not necessarily based on theories • expert group evaluates research results systematically • agreed upon criteria • systematic reviews, practice guidelines, technology assessment • application to clinical practice • Cochrane Collaboration, practice guidelines, regional guidelines • to write a systematic review takes several years • mostly quantitative despite efforts

  4. EVIDENCE IN NURSING • strong (philosophical) theories • more qualitative • patients are human beings • patient – centred thinking • knowledge through common experience • quality assurance
