Thank you for the opportunity to review the manuscript “Effects of a simulation-based education program on delirium care for critical care nurses A randomised controlled trial”.

Congratulations to the authors for their work, I found your paper a potentially very valuable resource on Health Science and therefore an interesting and relevant contribution to JAN.

The manuscript evaluates the effects of a simulation-based education program on critical care nurses’ knowledge, confidence, competence and clinical performance in providing delirium care.

However, before recommending publication of the manuscript, the authors must address the following concerns.
