Clinical Predictors of Dysphagia in Acute and Subacute Traumatic Cervical Spinal Cord Injury: A Retrospective Observational Study.

PMID 40784912WHAT IT FOUND
Patients with a tracheostomy after cervical spinal cord injury were far more likely to have food or liquid enter their airway.
Those aged 65 or older were more likely to have food left in the throat after swallowing. These factors help identify who needs a swallowing test before eating.
Key findings
01Having a tracheostomy was the strongest independent predictor of penetration or aspiration (food or liquid entering the airway) on the first swallowing X-ray study.
02Being aged 65 or older was an independent predictor of having mild-to-severe pharyngeal residue (food or liquid remaining in the throat after swallowing).
03Cervical spine alignment angles and neurological injury level were not significant independent predictors of swallowing problems in the final analysis.

What it does not show
This was a single-center retrospective study, so it could not prove that tracheostomy causes aspiration; it may just mark patients who are sicker. The timing of the swallowing test varied widely among patients (average 23.8 days, but with a large range), which might affect how severe the swallowing issues appeared. The study excluded patients with brain injuries or other conditions causing swallowing problems, so the results do not apply to those complex cases.
Declared interests
The study was funded by Pusan National University. No specific conflicts of interest were declared by the authors.
The easy way to misread this
Do not assume a tracheostomy directly causes aspiration. The study is retrospective, so the tracheostomy may simply be a marker of more severe injury or respiratory compromise that also causes swallowing problems.
