Spinal cord injury in severely injured patients: results from the Swiss Trauma Registry.

BACKGROUND AND OBJECTIVES

Traumatic spinal cord injuries (SCIs) in the context of severe trauma are rare, and patient demographics are infrequently reported. This study aimed to assess patient demographics in acute traumatic SCI in the context of severe injuries in Switzerland and to evaluate differences in demographics and outcomes stratified by timing of surgery.

METHODS

We analyzed data from the Swiss Trauma Registry (STR) from 2015 to 2024. The STR includes patients with major trauma (injury severity score [ISS] ≥ 16 and/or abbreviated injury scale [AIS] head ≥ 3) admitted to any level-one trauma centre in Switzerland. We evaluated patient characteristics, complications, and hospital outcomes, which were further stratified by early (< 24 h) and late (≥ 24 h) surgery.

RESULTS

Among 24,328 patients, 6,819 (28%) sustained spinal injuries, and 383 (1.6%) had a concurrent SCI with an incidence of 0.44 cases per 100’000 inhabitants. The median age was 52 years (IQR 31–70) and 73.6% were male. The primary causes were falls (63.1%) and road traffic accidents (29.6%). The in-hospital mortality rate was 4.7%. Late surgery patients more often had concomitant moderate or severe traumatic brain injuries (31% vs. 14%,  = 0.009) and were more likely to have no fractures or dislocations of the spine (22.8% versus 6.8%,  = 0.001). Patients who underwent early surgery had shorter hospital stays (9d [5-16], versus 16 d [9-24]; F = 13.92,  < 0.001). Late surgery was associated with a higher likelihood of developing two and more complications (OR 2.57, 95% CI 1.18–5.63,  = 0.018), including urinary tract infections (OR 12.13, 95% CI 2.76–53.41,  = 0.001) and multiple organ failure (OR 12.99, 95% CI 1.64-102.83,  = 0.015).

CONCLUSIONS

This study offers insights into the characteristics and outcomes of acute SCI care in severely injured patients. Despite its low incidence, the acute management of this patient population remains highly challenging. Our findings suggest early stabilization of spinal injuries in severely injured patients may reduce hospital stays and complications.
