Impact of Nutrition in the ICU

Evidence-based nutrition assessment has been shown to
potentially reduce LOS in the ICU as much as 2.9 days1

  • Approximately 40 - 50% of ICU patients are malnourished. 2,3,4
  • Malnutrition is associated with increased morbidity and mortality. 5-11
  • Predictive equations are accurate 30% of the
    time. 12,13,14
  • Average cost $4,772 per day. 15
