CINAHL has a limit for Evidence-Based Practice. You can access it by clicking in the Evidence-Based Practice check box or by choosing Evidence-Based Practice under Special Interest. Both of these options apply the same limits to your search.


This limit applies a preset collection of subject terms related to evidence-based practice to your search.
Within CINAHL, you can also try limiting to the following publication types (* denotes high level evidence):
- Case Study
- Clinical trials
- Meta analysis *
- Nursing interventions
- Randomized controlled trials *
- Systematic reviews *

If you would like to select more than one category at a time, hold the CTRL key down each time you make an additional selection.
