Cervical Collars and Dysphagia Among Geriatric TBIs and Cervical Spine Injuries: A Retrospective Cohort Study
Introduction:
Dysphagia, a complication of traumatic brain injuries (TBIs), can lead to death. Cervical collar (c-collar) restriction may increase the risk for dysphagia. The objective was to determine how c-collars affect dysphagia rates.
Methods:
This retrospective cohort study included geriatric TBIs or cervical spine injuries (January 2016 to December 2018) at a Level 1 trauma center. Outcomes (dysphagia, aspiration, and respiratory failure) were compared by c-collar placement.
Results:
There were 684 patients: 21.5% had a c-collar and 78.5% did not. Demographics, injury severity score, and Glasgow Coma Scale were comparable. Dysphagia (53.7% vs. 39.3%, p = .002) and respiratory failure (17.0% vs. 6.9%, p = .0002) were more common among patients with c-collars. Aspiration rates ( p = .11) were similar. After adjustment, patients with a c-collar had a significantly higher odds of dysphagia and respiratory failure. Among patients who did not receive swallow therapy, aspiration ( p = .02) and respiratory failure ( p < .0001) were more common for those with c-collars.
Conclusions:
C-collar placement increased the risk for dysphagia and respiratory failure. There was evidence that swallow therapy may modify the effect of c-collar placement. For patients who did not receive swallow therapy, aspiration was more common among those with a c-collar. Dysphagia screening among patients with a c-collar may improve patient quality.

The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
