“…The ICDSC with its good sensitivity (range, 64-99%, depending on the used cutoff values) and its continuous scoring system based on routine care observations, seems to be useful for delirium screening in daily practice [10,12,17]. Yet, lower sensitivity rates (range 43-47%) [15,18] have been reported, and inconsistencies regarding its optimal cutoff [16,17,19,20] and its use for screening and monitoring the severity of delirium in pragmatic ICU settings remain unclear [3,8,21,22]. Furthermore, the userfriendliness of the ICDSC for bedside nurses in monitoring ICU patientsa prerequisite for implementation in practice -is unexplored.…”
