To assess the consistency of caloric intake with American College of Chest Physicians (ACCP) recommendations for critically ill patients and to evaluate the relationship of caloric intake with clinical outcomes. ⋯ Study participants were underfed relative to ACCP targets. These targets, however, may overestimate needs because moderate caloric intake (ie, 33% to 65% of ACCP targets; approximately 9 to 18 kcal/kg per day) was associated with better outcomes than higher levels of caloric intake.
