Characteristics and Outcomes of Children and Young Adults With Sepsis Requiring Continuous Renal Replacement Therapy: A Comparative Analysis From the Worldwide Exploration of Renal Replacement Outcomes Collaborative in Kidney Disease (WE-ROCK)*
Bibliographic record
Abstract
OBJECTIVES: Pediatric sepsis-associated acute kidney injury (AKI) often requires continuous renal replacement therapy (CRRT), but limited data exist regarding patient characteristics and outcomes. We aimed to describe these features, including the impact of possible dialytrauma (i.e., vasoactive requirement, negative fluid balance) on outcomes, and contrast them to nonseptic patients in an international cohort of children and young adults receiving CRRT. DESIGN: A secondary analysis of Worldwide Exploration of Renal Replacement Outcomes Collaborative in Kidney Disease (WE-ROCK), an international, multicenter, retrospective study. SETTING: Neonatal, cardiac and PICUs at 34 centers in nine countries from January 1, 2015, to December 31, 2021. PATIENTS: Patients 0-25 years old requiring CRRT for AKI and/or fluid overload. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Among 1016 patients, 446 (44%) had sepsis at CRRT initiation and 650 (64%) experienced Major Adverse Kidney Events at 90 days (MAKE-90) (defined as a composite of death, renal replacement therapy [RRT] dependence, or > 25% decline in estimated glomerular filtration rate from baseline at 90 d from CRRT initiation). Septic patients were less likely to liberate from CRRT by 28 days (30% vs. 38%; p < 0.001) and had higher rates of MAKE-90 (70% vs. 61%; p = 0.002) and higher mortality (47% vs. 31%; p < 0.001) than nonseptic patients; however, septic survivors were less likely to be RRT dependent at 90 days (10% vs. 18%; p = 0.011). On multivariable regression, pre-CRRT vasoactive requirement, time to negative fluid balance, and median daily fluid balance over the first week of CRRT were not associated with MAKE-90; however, increasing duration of vasoactive requirement was independently associated with increased odds of MAKE-90 (adjusted OR [aOR], 1.16; 95% CI, 1.05-1.28) and mortality (aOR, 1.20; 95% CI, 1.1-1.32) for each additional day of support. CONCLUSIONS: Septic children requiring CRRT have different clinical characteristics and outcomes compared with those without sepsis, including higher rates of mortality and MAKE-90. Increasing duration of vasoactive support during the first week of CRRT, a surrogate of potential dialytrauma, appears to be associated with these outcomes.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
