Clinical Trial Summary

This multi-center retrospective cohort study presents a detailed assessment of augmented renal clearance (ARC) in a mixed population of adult critically ill patients. Epidemiology of ARC will be studied in detail in a very heterogeneous population. Risk factors for ARC will be identified and a predictive scoring system for ARC ready to use in clinical practice will be constructed and validated. Performance of estimators of kidney function will be measured and a cutoff for ARC will be determined for the best estimator. Finally clinical impact of ARC will be explored using vancomycine and aminoglycosides levels as surrogate marker.

Outcome

Type Measure Description Time frame Safety issue
Primary ARC incidence per day Incidence of ARC per 100 ICU days Retrospective analysis between January 2013 and December 2015
Primary ARC incidence per admission Incidence of ARC in % of ICU admissions: with ARC incidence defined as at least once, min. 50% of the measurements, 100% of the measurements during ICU admission) Retrospective analysis between January 2013 and December 2015
Primary Duration and course of ARC episodes ARC episodes: number of episodes (count), length of the episodes (days) and both combined to obtain relative contribution to ARC as a % ((count*length)/total ARC days) Retrospective analysis between January 2013 and December 2015
Primary ARC daily prevalence Daily prevalence of ARC (% of ARC days per ICU admission day) Retrospective analysis between January 2013 and December 2015
Primary Logistic regression with ARC as dependent variable Risk factors associated with ARC will be identified through logistic regression analysis on demographic and clinical data. Retrospective analysis between January 2013 and December 2015
Primary Predictive algorithm for ARC An algorithm predicting ARC on the next day(s) will be created using a backward selection logistic regression model on the risk factors associated with ARC detected in this study and/or in previously published studies. Retrospective analysis between January 2013 and December 2015
Primary Most precise formula using Bland-Altman agreement analysis Bland-Altman agreement analysis between CrCl24h and 3 commonly used serum creatinine based formulae estimating renal function (CKD-EPI, C&G, MDRD) will be used to identify the formula with the best precision (SD of the bias). Retrospective analysis between January 2013 and December 2015
Primary Performance of the best cutoff for ARC using ROC curve analysis Performance of the best cutoff for ARC using ROC curve analysis on the most precise formula estimating renal function. Retrospective analysis between January 2013 and December 2015
Primary Exploration of clinical impact of ARC via surrogate markers Vancomycin and aminoglycoside (amikacin & gentamycin) serum concentrations will be used as surrogate markers to evaluate potential clinical impact of ARC. Retrospective analysis between January 2013 and December 2015
