What is a systematic review?

According to the Cochrane Handbook for Systematic Reviews of Interventions, a systematic review has four key components:

  • "a clearly stated set of objectives with pre-defined eligibility criteria for studies
  • an explicit, reproducible methodology
  • an assessment of the validity of the findings of the included studies, for example through the assessment of risk of bias; and
  • a systematic presentation, and synthesis, of the characteristics and findings of the included studies." 1

What is a rapid review?

According to the International Journal of Technology Assessment in Health Care, "there is no universally accepted definition of what constitutes a rapid review," but they generally take around 5 weeks to complete, contain limited sources, and have a broad rather than focused PICOS. Unlike systematic reviews, rapid reviews use limited or cautious interpretations of findings. 2
