AimTo analyze knowledge and experience in the diagnosis and management of acute renal failure (ARF) and the use of renal replacement therapy (RRT) in different Spanish Intensive Care Units (ICUs).DesignA case series with a survey conducted by the Nephro-Intensive Care Working Group of the SEMICYUC was compiled between January and November 2011.ScopeSpanish national ICUs.InterventionsA survey of 28 questions with multiple and open responses.ParticipantsThe survey was sent to 99 ICUs. Volunteers consisting of the medical staff belonging to the 51 ICUs that responded. Main variables of interest General characteristics of hospitals and ICUs, definitions of ARF and RRT (indications and management).ResultsRIFLE/AKIN scales to define ARF (47%). ARF diagnosis: plasma creatinine (80.4%), creatinine clearance (52.9%). Protocols for RRT: 72.5%. RRT in non-renal indications: 70.6%. Indications for initiation of RRT: oliguria, increased creatinine and urea. End of RRT: increased diuresis. RRT dose: 21-35 ml/kg/h (41.2%), 36-45ml/kg/h (33.3%).ConclusionsThere is great variability in the ARF detection methods, and adequate incorporation of the RIFLE/AKIN systems to daily clinical practice in the ICU is still lacking. Written protocols aimed at establishing an early diagnosis of ARF are needed, based on these systems. On the other hand, there is growing interest in RRT, despite the fact that there are no definitive indications or guidelines on the use and handling of such techniques.Copyright © 2013 Elsevier España, S.L.U. and SEMICYUC.
