It is an acute neuropsychiatric syndrome. The aim of this study was to analyze the CARDEL Index, composed of advancing age, preoperative glycated hemoglobin and the platelet-to-WBC ratio (PWR) previously described and calculated, using a different patient database, to assess its usefulness as a marker for predicting postoperative delirium after coronary artery by-pass grafting (CABG).Methods: A retrospective analysis of 1098 patients who underwent, isolated CABG procedures between 2017 and 2019 was performed.Results: Within the study group, 164/1098 (14.93%) patients were diagnosed with delirium. Preoperative inflammatory parameters were elevated in patients with delirium: White Blood Cell count (p=0.003), Neutrophil count (p=0.016) and C-reactive protein (p< 0.001). A decrease in preoperative PWR was shown in patients with delirium (p=0.008). Delirious patients spent more time mechanically ventilated (p< 0.001) and had longer hospitalization times (p=0.002). Mortality at 1 year was significantly higher in patients with POD (p< 0.001). The CARDEL Index in this study group for POD detection has the largest area under the curve (AUC) of 0.664 (p< 0.001) and a cut-off value of 8.08.Conclusion: CARDEL Index may be treated as a potentially valuable tool for delirium prediction in patients after CABG.Keywords: delirium, POD, CAM-ICU, cardiac surgery, CABG, coronary artery bypass grafting |
