Time to Rehabilitation Admission and Associated Outcomes for Patients With Traumatic Brain Injury

Kunik CL, Flowers L, Kazanjian T. Time to rehabilitation admission and associated outcomes for patients with traumatic brain injury.ObjectiveTo examine the association between time from injury to rehabilitation admission and outcomes for patients with traumatic brain injuries (TBIs).DesignRetrospective chart review.SettingOne hundred–bed inpatient rehabilitation facility with a 20-bed brain injury unit.ParticipantsPatients with TBIs discharged from initial inpatient rehabilitation between 2003 and 2004 (N=158).InterventionsNot applicable.Main Outcome MeasuresOutcomes examined were functional independence at discharge (motor, cognitive, total FIM scores), rehabilitation length of stay (LOS), and rehabilitation cost.ResultsSignificant linear trends were observed for time to admission and motor FIM scores, total FIM scores, rehabilitation LOS, and cost. All linear regression models contained time to admission as a significant predictor of rehabilitation outcomes. Over half of the variability in outcomes was explained by predictors including time to admission and case-mix group or individual FIM scores with the exception of discharge motor FIM score, for which only 45% of the variability was explained.ConclusionsPatients who progress to rehabilitation earlier do better functionally and have lower costs and shorter LOSs. Furthermore, the time to rehabilitation admission is easily calculated and could be used by rehabilitation providers in adjunct with admission FIM scores to estimate resource utilization.
