Evidence-Based Practice and Systematic Reviews

Evidence-Based Practice

Evidence-based practice (EBP, Evidence-Based Medicine, or Evidence-Based Nursing), is a systematic process of appraising and using current research findings. The process includes these steps:

  • formulating a clear clinical question of patient needs
  • searching the current literature 
  • evaluating the literature and deciding which studies are valid and useful to the patient
  • applying the findings to the patient's care
  • evaluating the outcome

Systematic Reviews

A systematic review focuses on a single question and tries to identify, appraise, select and synthesize all high-quality research evidence relevant to that question. It often uses the same techniques as the meta-analysis to combine valid research studies. The seven steps for preparing a systematic review as outlined by the Cochrane Handbook are:

  • formulating the problem
  • locating & selecting studies 
  • critical appraisal of the studies 
  • collecting data,
  • analyzing & presenting results
  • interpreting the results
  • improving & updating the systematic review
