Objective: CIN is the most common non-cardiac complication following coronary angiography, however riskstratification for CIN can be cumbersome. We hypothesize that a computer-based Kidney Injury Risk Tool (KIRT) would assess contrast-induced nephropathy (CIN) risk accurately and may out-perform standard clinical estimation. Methods: This was a prospective study of all-comers undergoing coronary angiography at a single institution. KIRT is based upon an established risk model and risk factors were derived from the electronic medical records using phenotyping rules. Operator reported and KIRT-derived risk factors were compared against adjudicated ground truth obtained by a blinded investigator through chart review and accuracy of the risk model outputs were compared. Operator’s assessment of risk without risk model vs. KIRT assessment were compared and analyzed (Wilcoxon-test, an.. View More»
