Building a search in CINAHL

Three tips to make CINAHL work for you

Preparing for a systematic search

Your research project may include a systematic review, scoping review, or other knowledge synthesis. These reviews have their own methodologies and normally involve systematically searching the literature in a thorough, transparent, and reproducible way. You will want to formulate a review question when conducting such reviews.

Systematic searching can also be used as a technique to search the literature in general.
