Lindroth H, et al. - Given the importance of delirium as a postoperative complication, researchers investigated if postoperative delirium severity could be predicted using the NSQIP risk calculation for serious complications (NSQIP-SC) or risk of death (NSQIP-D), and cognitive tests of executive function (Trail Making Test A and B [TMTA, TMTB]). Further, they sought to demonstrate the possible utility of advanced statistical techniques to identify candidate predictors. They performed an analysis of data from an ongoing perioperative prospective cohort study of 100 adults (>65yo) undergoing non-cardiac surgery. Outcomes suggest that postoperative delirium severity could be predicted with NSQIP Risk score for Serious Complications and a measure of executive function, TMT-B, using advanced modeling techniques.
