The previous issue of Critical Care reports a multi-centre study showing that a higher than conventional dose of RRT whether continuous RRT or intermittent RRT is not associated with better survival of these patients. This commentary highlights some of the problems associated with the interpretation of this and previously published studies. These problems include the use of targets of Kt V urea or the ultrafiltration rate in millilitres per kilogram body weight the latter quite difficult to estimate in these patients the divergent co-morbidities of the patients and the local experience of intensivists or nephrologists with either continuous RRT or intermittent RRT. The last factor could explain why some single centre studies did find an impact of dialysis dose on the survival of these patients whereas multi-centre studies did not. In the previous issue of Critical Care an article by Vesconi and colleagues 1 describes the impact of the dose of renal replacement therapy RRT on clinical outcomes in critically ill patients with acute kidney injury. This study was performed in a number of European intensive care units ICUs . Dialysis dose was defined as more intensive continuous RRT CRRT 35 ml kg h intermittent RRT IRRT 6 sessions week or less
