PMID 40900564WHAT IT FOUND
A Brazilian Portuguese postoperative pain questionnaire was understood by patients and gave consistent scores when two researchers used it.
It can help nurses assess pain, side effects, sleep, mobility and satisfaction after surgery.
Key findings
01The Brazilian Portuguese IPO was pretested with 30 patients, and all of them reported clearly understanding the questions.
02In 360 postoperative patients, the Brazilian Portuguese IPO showed strong to very strong correlations with the Brief Pain Inventory for conceptually similar items.
03Two researchers administering the IPO to 54 patients obtained Kappa values of 1 and ICC values above 0.999.

What it does not show
The study was done in one surgical clinic unit in Brazil with non-probabilistic samples, so it may not apply to all hospitals or all postoperative patients. Patients needed to be conscious and able to converse at least 24 hours after surgery, so it does not show performance in confused, very ill, or non-communicative patients. It tested measurement properties, not whether the questionnaire improves pain management or patient outcomes. Interobserver reliability was assessed in only 54 patients.

The easy way to misread this
Do not conclude that the Brazilian Portuguese IPO improves postoperative pain care. It was validated as a measurement tool, not as a treatment, and the study did not show that using it changes patient outcomes.
