peer reviewed journals are publications that include only those articles that have been reviewed and/or qualified by a selected panel of acknowledged experts in the field of study covered by the journal.

Research articles indicate an original complete research study containing methodology, discussion or results, etc.

Evidence-based practice includes "research" articles (systematic reviews, clinical trials, meta analysis, etc.) as well as articles from evidence-based practice journals, articles about evidence-based practice, and commentaries on research studies. *Every result may not be an evidence-based study*

Step 4


More Limiting Strategies
  • Limit to publication type: Systematic Review (indicates a research process in which a concept is identified and the research that has studied it is analyzed and evaluated. Results are synthesized to present the current state of knowledge regarding the concept. Includes integrated or integrative reviews).
  • Browse the many Publication types; notice the range from case study or letter (lower levels of evidence) to Systematic Reviews and Clinical Trials (higher levels of evidence).
  • Using the CINAHL “Evidence-based Practice” limiter includes “Research” articles (including systematic reviews, clinical trials, meta analyses, etc.)  as well as articles from evidence-based practice journals, articles about evidence-based practice, and commentaries on research studies (applying practice to research). Use with caution; every result may not be an evidence-based study.
Advanced Searchers:  
  • Limit using Clinical Queries filter in five research areas:  Therapy, Prognosis, Review, Qualitative, Causation (Etiology)
  • High Sensitivity is the broadest search, to include ALL relevant material. It may also include less relevant materials.
  • High Specificity is the most targeted search to include only the most relevant result set. May miss some relevant materials.
  • Best Balance retrieves the best balance between Sensitivity and Specificity.
