Comparison of cervical versus thoracic spinal cord injury outcomes in pediatric trauma patients.

Abstract

Purpose: To explore differences based on level of pediatric spinal cord injury (SCI), we compared cervical and thoracic SCI in pediatric trauma patients (PTPs), hypothesizing higher mortality and length of stay (LOS) for cervical SCI.

Methods: The 2017-2021 Trauma Quality Improvement Program was queried for all PTPs ≤ 17 years-old with cervical or thoracic SCI. Bivariate analyses compared the two groups. The primary outcome was mortality and secondary outcomes included hospital LOS and injury severity scores (ISS). Logistic regression models were used to determine independent risk factors for death and prolonged ventilation.

Results: Of 5280 PTPs, 2538 (65.9%) had cervical SCI and 1316 (34.1%) had thoracic SCI. Motor vehicle collisions were the most common cause of both cervical and thoracic SCI (37.8 and 41.9%). PTPs with thoracic SCI had higher rates of positive drug screen as compared to cervical SCI (39.2 vs 29.8%, p = 0.001). PTPs with thoracic SCI had higher median ISS (25 vs 16, p < 0.001), while cervical SCI had higher mortality (13 vs 6.1%, p < 0.001) but decreased hospital LOS (median 9 vs 5 days, p < 0.001. Cervical SCI were associated with a nearly fourfold increase in the risk of death (95% CI 2.750-5.799, p < 0.001) and a 1.6-fold increase in the risk of prolonged ventilator requirement (95% CI 1.228-2.068, p < 0.001).

Conclusions: PTPs with cervical SCI have higher mortality while those with thoracic SCI have higher ISS and hospital LOS. Cervical SCI were associated with a fourfold higher risk of death. MVC was the most common cause of injury, and both groups had high rates of positive drug screens. Understanding differing outcomes may assist providers with prognostication and injury prevention.
