Demographics of traumatic brain injury and outcomes of continuous chain of early rehabilitation in Singapore

Abstract

Background: Evidence shows that early initiation of a continuous chain of rehabilitation is associated with better functional outcomes in traumatic brain injured patients. The Department of Rehabilitation Medicine initiated early screening and review of patients with all traumatic brain injury (TBI) severity within 72 hours of acute admission, followed by direct transfer of suitable patients to acute inpatient rehabilitation (AIR). Objectives: This study aim to document the demographics and clinical characteristics of all TBI patients admitted to the local acute hospital; determine the characteristics of patients with TBI who are directly transferred to AIR following early screening and review; and determine clinical predictors affecting functional outcomes of patients of all TBI severity. Methods: A total of 491 patients were screened and reviewed; 116 patients were directly transferred to AIR. Results: The median age of the screened cohort was 67.0 years (interquartile range 50.0–77.0 years). Falls were the leading mechanism of TBI. Infection (odds ratio (OR)=2.95, 95% confidence interval (CI) 1.59–5.49) and neurosurgical intervention (OR=2.18, 95% CI 1.24–3.81) increased the odds of transfer to AIR. The Functional Independence Measure (FIM) gain after receiving AIR was significant ( p <0.001). Increased age, complications, high motor admission FIM (AFIM) and long rehabilitation length of stay (RLOS) were negatively associated with FIM gain and FIM efficiency. Conclusions: Our study demonstrated that falls were the leading mechanism of TBI, with the majority of patients being older. Infection and neurosurgical intervention increased the likelihood of transfer to AIR. There was functional improvement after AIR. Age, complications, motor AFIM and RLOS were negatively associated with FIM gain and FIM efficiency. Further local research is warranted to confirm these findings.
