CINAHL: Cumulative Index to Nursing and Allied Health Literature: Hedges

Hedges: Definition and how to apply

Hedges are standardized search strategies that can be used to help retrieve relevant articles. Hedges may be applied to improve the recall of various levels of evidence, such as randomized controlled trials, systematic reviews/meta-analyses, and to identify clinical concepts, such as diagnosis, etiology, prognosis and treatment. Hedges are also called filters, clinical queries, or optimal search strategies. They are not a guarantee of retrieving quality research; you will still need to critically appraise results for quality and relevance.

To apply these filters, copy and paste into the search box in the advanced search in CINAHL, then click search:
