PMID 39319973WHAT IT FOUND
A 30-item guide for women after breast surgery was judged clear and relevant by expert nurses and physiotherapists, but it was not tested with patients or shown to improve recovery.
Key findings
01The initial guide contained 37 items and the final guide contained 30 items.
02Items 31 and 36 were removed because they did not reach the relevance cut-off.
03For practical relevance, no item other than the removed items fell below the cut-off.

What it does not show
No patients or families were involved; the guide was judged only by 15 expert judges. Only two professional categories, nursing and physiotherapy, rated the guide, so other perspectives were missing. The study validated content only; other forms of validity were not tested. 80% of judges were nurses and 93.3% were from Northeast Brazil, so the ratings may not reflect other professional or regional views.
The easy way to misread this
Do not treat the 30-item guide as proven to improve self-care or recovery. It was rated only by expert judges, not tested with patients, and no patient outcomes were measured.
