Method
Relevant literature was located by first accessing research articles in peer‑reviewed publications that related to CS and nursing. A total of 32 articles were retrieved. In selecting articles for review, the following criteria were then applied: the article reported an evaluation of the effectiveness of CS; the participants in the study included qualified nurses (not students or generic health care workers); the approach to CS was clearly described; and, the method of data collection and analysis, either quantitative and/or qualitative, was explained in detail.
