The value of trauma scores - Predicting discharge after traumatic brain injury

Objective: To determine the association of acute variables with disposition after acute hospitalization. Design: Revised Trauma Score (RTS), Injury Severity Score (ISS), and the Co mbined Trauma Score Injury Severity Score (TRISSRTS) were compared with dis charge disposition after acute hospitalization of 378 consecutive patients who sustained a traumatic brain injury (TBI) and were treated at a level 1 trauma center between September 1997 and May 1998. Results: Logistic regression modeling found TRISSRTS to predict discharge t o home with or without home health assistance or inpatient rehabilitation v s. nursing home placement or death. Subsequent modeling, excluding patients who died or went to nursing homes, identified RTS and ISS as predictors of discharge to home with or without home health vs. inpatient rehabilitation . A sensitivity of 97.78% and 93.91% were achieved with these two models wh en tested on a population of 4,625 patients with TBI treated during the las t 10 yr at the same facility. Conclusions: The results suggest that RTS, ISS, and TRISSRTS are predictors of discharge disposition after acute hospitalization with TBI and may be u seful measures of rehabilitation services resource planning early in the co urse of TBI management.
