Bioelectrical impedance analysis-derived phase angle at admission as a predictor of 90-day mortality in intensive care patients

摘要

Background/ObjectivesA low bioelectrical impedance analysis (BIA)-derived phase angle (PA) predicts morbidity and mortality in different patient groups. An association between PA and long-term mortality in ICU patients has not been demonstrated before. The purpose of the present study was to determine whether PA on ICU admission independently predicts 90-day mortality.
