Study examined the association of enteral nutrition (EN) with patient preinjury and injury characteristics and outcomes for patients receiving inpatient rehabilitation after traumatic brain injury (TBI). Participants were 1,701 patients admitted to 1 of 9 rehabilitation centers participating in a comparative effectiveness study in which patient characteristics, environmental factors, and interventions were evaluated to identify factors associated with key TBI inpatient rehabilitation outcomes. Outcome variables examined to assess the association with EN were discharge Functional Independence Measure (FIM) motor and cognitive scores, weight loss during rehabilitation, length of stay, and various infections (aspiration pneumonia, pneumonia, urinary tract infections, and sepsis). The results indicated that there were many signiﬁcant differences in preinjury and injury characteristics between patients who received EN and patients who did not. After matching patients with a propensity score of greater than 40 percent for the likely use of EN, patients receiving EN with either a standard or a high-protein formula (more than 20 percent of calories coming from protein) for more than 25 percent of their rehabilitation stay had higher FIM motor and cognitive scores at rehabilitation discharge and less weight loss than did patients with similar characteristics not receiving EN.
