PMID 40233209WHAT IT FOUND
After bypass heart surgery, ICU patients with acute kidney injury had higher SAPS 3 and SOFA scores than those without injury.
The scores tracked severity, but this small single-center cohort does not show they should change care.
Key findings
01Of 74 analysed patients, 23 developed AKI, and KDIGO 1 and KDIGO 2 predominated.
02SAPS 3 and SOFA scores were higher in the AKI group and significantly associated with AKI.
03Of the 23 patients with AKI, 20 were diagnosed early within 48 hours and three were late.

What it does not show
The study was single-center and used convenience sampling, so it may not apply to other ICUs or patients. Only 74 patients were analysed, and the authors said the sample size was limited. AKI was classified using creatinine only, not urine output, because urinary volume recording was inaccurate. The study is observational and did not test a treatment, so it cannot show that SAPS 3 or SOFA improve outcomes. Data came from medical records, which the authors said created a risk of measurement bias.
Declared interests
Partly funded by the Brazilian National Council for Scientific and Technological Development (CNPq, process 4.192.306.0001/2023-9). The authors declared no conflicts of interest.
The easy way to misread this
Do not conclude that SAPS 3 or SOFA improve acute kidney injury outcomes. This was a retrospective single-center cohort of 74 patients, and it reports associations rather than a tested treatment.
