Predictive value of APACHE II score is improved by combination with bioelectrical impedance analysis in multiple trauma patients
Critical Care volume 2, Article number: P162 (1998)
40 (30 male/10 female) multiple trauma patents (age: 16-81 years) with a stay of >5 days on the Intensive Care Unit (ICU) were studied retrospectively. Routinely obtained daily measurements of nutritional status (BIA 101 Impedance Analyser, RJL-Systems) included calculations of PA.
10/40 patients (25%) died during ICU stay (Table). In all patients with AP II scores ≥20 (APACHE II-Class ≥5) determination of outcome would have been correct by Phase-Angle: all deceased patients had a PA <3, while surviving patients had a PA >4 (P < 0.05). Discriminance analysis of this data reveals a probability of 100% for prediction of survival and 94% for lethal outcome respectively.
Even in this small sample of multiple trauma patients there is a clear cutoff level of PA >4 for prediction of survival. We suggest the routine use of BIA for observation of ICU patents, but further studies are needed to establish the prognostic relevance of this method.
