Phase angle assessment in critically ill cancer patients: Relationship with the nutritional status, prognostic factors and death.

Abstract:

PURPOSE:To evaluate the relationship between phase angle (PA) and nutritional status and the prognostic significance of PA in critically ill cancer patients. METHODS:31 patients that had been admitted to the intensive care unit (ICU) of a center on oncology were evaluated. Their PA was obtained from their bioelectrical impedance within 48 h of the ICU admission. The logistic regression analysis of Cox was used in order to identify the independent predictors of the outcomes. RESULTS:Negative and significant correlations were observed between the PA and the following variables: the length of hospital ward stay, the length of ICU stay, the total time of hospital stay, the mechanical ventilation time, and the acute physiology and chronic health evaluation II (APACHE II) scores. A positive correlation was ascertained between the PA and albumin. PA was significantly associated with death. Patients with a PA ≤3.8° presented a significantly shorter survival time than those with a PA >3.8°. CONCLUSION:PA was a prognostic marker in this population, independently of previously established prognostic factors. PA can represent a clinically feasible approach for the initial identification of critically ill cancer patients who require an early and specialized nutritional intervention.
