Content validation of the nursing diagnosis "Insufficient breast milk production (00216)"

To review and validate the elements of the nursing diagnosis (ND) "Insufficient breast milk production" (00216) based on the literature and expert consensus, and to construct operational definitions (ODs) for its defining characteristics (DCs).

It is a methodological study carried out in two phases. In the first phase, a scoping review was conducted, and in the second, a committee of experts reviewed the elements' content. Items with a Content Validity Index ≥0.8 were validated for relevance, clarity, and precision. Discussions were conducted until a consensus was reached on all items and criteria evaluated. The Ethics Committee approved the study.

The final scoping review sample consisted of 61 articles, and 19 experts evaluated the content of the ND. All DCs were revised. Three at-risk populations, three associated conditions, and one related factor were added. Three elements had their category changed, and an element was deleted. Experts also validated ODs developed for all DCs.

"Insufficient breast milk production (00216)" was validated by experts. This study improved the ND through literature and expert consensus. New elements were added, and existing ones were revised.

This study improves this ND based on scientific evidence and clinical expertise and potentially improves nurses' diagnostic accuracy through ODs.
