Abstract
Background
Predicting morbidity and mortality in a pediatric intensive care unit (PICU) is of extreme importance to make precise decisions for better outcomes.
Aim
We compared the urine albumin creatinine ratio (ACR) with the established PICU score, pediatric index of mortality 2 (PIM 2) for predicting PICU outcomes.
Methods
This cross-sectional study enrolled 67 patients admitted to PICU with systemic inflammatory response syndrome. Urine ACR was estimated on admission, and PIM 2 score was calculated. ACR was compared with PIM 2 for PICU outcome measures: the need for inotropes, development of multiple organ dysfunction syndrome (MODS), duration of PICU stay, and survival.
Results
Microalbuminuria was found in 77.6% of patients with a median ACR of 80 mg/g. ACR showed a significant association with the need for inotropes (p < 0.001), MODS (p = 0.001), and significant correlation to PICU stay (p 0.001, rho = 0.361). The area under the receiver operating characteristic curve for ACR (0.798) was comparable to that of PIM 2 (0.896). The cutoff value of ACR derived to predict mortality was 110 mg/g. The study subjects were divided into 2 groups: below cutoff and above the cutoff. Outcome variables, inotrope use, MODS, mortality, and PICU stay compared between these subgroups, were statistically significant.
Conclusion
ACR is a good predictor of PICU outcomes and is comparable to PIM 2 for mortality prediction.
