Mixed studies review/mixed methods review

Different types of reviews

  • a clearly stated set of objectives with pre-defined eligibility criteria for studies;
  • an explicit, reproducible methodology;
  • a systematic search that attempts to identify all studies that would meet the eligibility criteria;
  • 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.

A literature review is something most of you have done this at one time or another. As a publication type it is an article or book published after examination of previously published material on a subject. It may be comprehensive to various degrees and the time range of material scrutinized may be broad or narrow, but the reviews most often desired are reviews of the current literature. The textual material examined may be equally broad and can encompass, in medicine specifically, clinical material as well as experimental research or case reports.

Search strategies do not need to be replicable

  • The writers assumptions and agenda often unknown
  • Biases that occur in selecting and assessing the literature are unknown
  • Cannot be replicated
  • Describes and appraises previous work but does not describe specific methods by which the reviewed studies were identified, selected and evaluated

Technique that statistically combines the results of quantitative studies to provide a more precise effect of the results.
