Study Notes

Appraising Systematic Reviews

  • A systematic review is a secondary research study that summarizes information from multiple primary studies.
  • It is characterized as a "study of studies" that provides comprehensive information regarding findings from several sources with an analysis of the methodological quality of the studies.
  • Systematic reviews can be extended by pooling data from several studies in a process of meta-analysis.

Key Questions for Appraising Systematic Reviews

  • Determining Applicability:
    • Is the study's purpose relevant to my clinical question?
    • Are the inclusion and exclusion criteria clearly defined and are studies that would answer my clinical question likely to be included?
    • Are the types of interventions investigated relevant to my clinical question?
    • Are the outcome measures relevant to my clinical question and are they conducted in a clinically realistic manner?
    • Is the study population (sample) sufficiently similar to my patient to justify expectation that my patient would respond similarly to the population?
  • Determining Quality:
    • Was the literature search comprehensive?
    • Was an objective, reproducible, and reliable method used to judge the quality of the studies in the systematic review?
    • Was a standardized method used to extract data from studies included in the systematic review?
    • Was clinical heterogeneity assessed to determine whether a meta-analysis was justified?

Interpreting Results of a Systematic Review

  • If a meta-analysis was conducted, was statistical heterogeneity assessed?
  • What methods were used to report the results of the systematic review?

Summarizing the Clinical Bottom Line of a Systematic Review

  • How does the systematic review inform clinical practice related to my clinical question?
