Description of intervention(s) / exposure
A retrospective observational trial where critically ill children subjected to acute kidney injury undergoing continuous renal replacement therapy (CRRT) are characterized. Patients are identified in the ICU database. The patients are primary studied to elucidate if ability to achieve or not to achieve negative water balance within the first 72 hours after CRRT is initiated is associated with increased mortality rate. The patients are observed during the entire PICU stay.

Comparator / control treatment
Survivors will be matched to non-survivors for potential confounders: age, gender, comorbidity, degree of fluid overload, degree of multiple organ failure and circuit life span.
Control group
Active

Outcomes
Primary outcome [1] 301694 0
Occurrence of water imbalance defined as inability to achieve cumulative negative water balance within 72 hours after CRRT initiation as reported in medical records and its possible association with increased mortality.
Timepoint [1] 301694 0
Ability to acheive negative water balance within 72 hours after CRRT initiation (yes or no).
Primary outcome [2] 302082 0
Mortality
Timepoint [2] 302082 0
Mortality occurring during PICU stay.
Secondary outcome [1] 333582 0
Fluid overload (FO) defined as cumulative FO from admission until the initiation of CRRT. FO will be calculated as: FO % = ml fluid in - fluid out from admission to the PICU divided by admission weight.
Timepoint [1] 333582 0
FO occurring from PICU admission until CRRT initiation.
Secondary outcome [2] 333583 0
Circuit life span defined as the median survival time of dialysis filter
Timepoint [2] 333583 0
Circuit life span during CRRT.
Secondary outcome [3] 333584 0
The severity of illness (6 organ failures: neurological, respiratory, circulatory, renal, immunological and liver) measured at admission to the PICU by medical records
Timepoint [3] 333584 0
At admission to the PICU.

Statistical methods / analysis
Student’s t-test, Wilson matched pair test, One-way ANOVA followed by Tukey’s post hoc test, will be used when applicable using GraphPad Prism 5 (GraphPad Software, Inc.7825 Fay Avenue, Suite 230 La Jolla, CA 92037 USA).
Potential predictors of mortality (where water balance during the first 72 hours after CRRT initiation is the primary variable) will be analyzed by univariate logistic regression followed by step-wise backward multiple logistic regression using the software NCSS 2007, Kaysville, Utah. Only factors with p < 0.1 will be used in the multiple logistic regression.
