Abstract
STUDY DESIGN: Retrospective cohort study. OBJECTIVES: To evaluate the effects of older age at the time of injury on the individuals' survival and neurological recovery within the first year after acute traumatic spinal cord injury (tSCI). SETTING: United States. METHODS: This study included all participants enrolled into the First National Acute Spinal Cord Injury Study (NASCIS-1). Outcome measures included survival and neurological recovery (as assessed using the NASCIS motor and sensory scores) within the first year after tSCI. Data analyses of neurological recovery were adjusted for major potential confounders. RESULTS: The study included 39 females and 267 males with overall mean age of 31 years who mostly sustained cervical severe tSCI after motor vehicle accidents or falls. Survival rates among older individuals are significantly lower than among younger individuals within the first year following tSCI (p < 0.0001). Among who survived the first year of tSCI, there were no statistically significant difference between older survivors and younger survivors regarding motor and sensory recovery in the multiple regression analyses adjusted for major potential confounders. CONCLUSIONS: The results of this retrospective study suggest that older age at the injury onset is associated with lower survival rate within the first year following tSCI. However, older individuals have similar potential to recover from their initial neurological impairment to younger individuals after tSCI. The results of this study combined to the recent literature underline the need for multidisciplinary team approach to the management of the elderly with acute SCI is essential to maximize their recovery.
