ObjectiveTo determine the association of enteral nutrition (EN) with patient preinjury and injury characteristics and outcomes for patients receiving inpatient rehabilitation after traumatic brain injury (TBI).DesignProspective observational study.SettingNine rehabilitation centers.ParticipantsPatients (N=1701) admitted for first full inpatient rehabilitation after TBI.InterventionsNot applicable.Main Outcome MeasuresFIM at rehabilitation discharge, length of stay, weight loss, and various infections.ResultsThere 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 >40% for the likely use of EN, patients receiving EN with either a standard or a high-protein formula (>20% of calories coming from protein) for >25% 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.ConclusionsFor patients receiving inpatient rehabilitation after TBI and matched on a propensity score of >40% for the likely use of EN, clinicians should strongly consider, when possible, EN for ≥25% of the rehabilitation stay and especially with a formula that contains at least 20% protein rather than a standard formula.Copyright © 2015 American Congress of Rehabilitation Medicine.
