Irritable Bowel Syndrome.

This is a narrative review, not a new trial, so it does not provide original outcome data. The paper does not describe a systematic search or appraisal method, so it may not include all relevant evidence. The nurse-delivered self-management program combined cognitive-behavioral strategies, diet, relaxation, and education, so the contribution of any single component cannot be separated. The nursing practice suggestions are based on the authors' interpretation, not on a tested nursing intervention. Some treatments discussed, such as biomarkers and fecal microbiota transplantation, are not established for routine clinical use.

Do not read the nurse-delivered self-management finding as evidence that education alone works. The intervention included cognitive-behavioral strategies, diet, relaxation, and education, and the paper does not separate their effects.
