140 patients were evaluated for eligibility (Fig. Patient flow-chartPostoperative delirium was diagnosed using the CAM-ICU in 16 patients (12 men, 12.7%) and using the Nu-DESC in 10 patients (6 men, 7,9%) (Table Patient characteristics in patients with and without postoperative deliriumThe CAM-ICU was used as reference test for POD. Due to the small number of patients, COPD, Asthma and emphysema as well as all stages of renal failure, respectively, were grouped together. Data are shown as absolute number or mean and SD. Statistical significance with * p < 0.05The incidence of the postoperative delirium was highest on postoperative day 1 in the morning (9 patients, 7.6%). Men (n = 12, 21.1%) were diagnosed significantly more often (p = 0.02) with a delirium than women (n = 4, 6.6%) and this was still significant after multiple comparisons (p = 0.031). There was no association between the incidence of delirium and the duration of anaesthesia (120.3 ± 27 min, p = 0.352) or the duration of surgery (44.0 ± 21 min, p = 0.481). Besides the aortic stenosis patients were diagnosed with relevant cardiac comorbidities (Table The mean scoring in the MMSE was 26.4 ± 3.3 points, with a minimum of 13 points. The attained score did not differ between female and male patients (female: 61, male 57, p = 0.341). Patients who did not develop POD (26.8 ± 2.8) achieved a significant higher scoring in the MMSE (p = 0.0012) than patients who developed a POD (23.6 ± 4.5) at any time point postoperative (Table
