Background
Most pediatric continuous renal replacement therapy(CRRT) outcome studies focus on crude mortality. Recent data highlighted incomplete recovery and dialysis dependency in pediatric acute kidney injury treated with dialysis. We described midterm outcomes and renal recovery in pediatric CRRT.
Methods
Multicenter cohort study between 2/14-2/20. Primary outcome was Major Adverse Kidney Events at 90 days(MAKE90), secondary outcome was renal recovery (noMAKE90 in survivors).
Results
419 patients received CRRT for 9 days (IQR3-21) (age 93 mo (17-180), 51% male).PELOD2 was 9(7-14), 55% were ventilated, 67% were on vasoactives. 276(66%) patients had MAKE90 (61% dead, 21% dialysis dependent,18% persistent renal dysfunction). ICU admission reason, peak mean airway pressure, thrombocytopenia, and leukopenia were associated with MAKE90. Urine output at CRRT start was independently associated with renal recovery, each ml/kg/h was associated with 47%(95%CI 12-235%) increased odds of renal recovery.
Conclusion
Majority of pediatric CRRT patients develop MAKE90. Worse lung disease requiring higher respiratory support is independently associated with MAKE90, while admissions for metabolic/endocrine reasons are more likely to survive with intact renal function. Urine output at CRRT start is an independent predictor of renal recovery among pediatric CRRT survivors.
