- W4297181911 abstract "The aim of this study was to ascertain the accuracy of phase angle (PhA) as a predictor of mortality during intensive care unit (ICU) stay (MICU) and at 28 (M28) and 60 d (M60) after ICU admission among patients aged >60 y.Patients aged >60 y who were under mechanical ventilation (MV) ≥48 h were included once they were hemodynamically stable. PhA was measured by single-frequency bioelectrical impedance analysis up to 48 h after admission. ICU prognostic scores, functional scale, and nutritional assessments were performed in the first 24 h. Patients were followed for 60 d after ICU admission.We enrolled 102 patients into the present study. PhA was significantly higher (P < 0.001) in survivors at MICU, M28, and M60. Areas under the receiving operator characteristic curves for MICU, M28, and M60 were 0.77 (95% confidence interval [CI], 0.67-0.86), 0.71 (95% CI, 0.60-0.82), and 0.71 (95% CI, 0.60-0.81), respectively. The PhA cutoff to predict mortality was 3.29° for males at MICU, M28, and M60 and lower for females at M28 (2.63°) and M60 (3.01°). PhA better discriminated M60 than conventional prognostic scores. Logistic regression showed that even after controlling for other factors, PhA was a protective factor against late mortality. Survival analysis at 60 d revealed that low PhA was associated with lower median survival (18 versus 58 d; log-rank P < 0.001).Low PhA values are associated with higher late mortality and a short survival time at 60 d in critically ill older adults. Low PhA values can be considered a useful ICU prognostic score in similar populations." @default.
