Abstract

Objective

Dysphagia is a common symptom with associated complications ranging from mild discomfort to life-threatening pulmonary compromise. Videofluoroscopic swallow is the ‘gold standard’ evaluation for oropharyngeal dysphagia, but little is known about how patients’ performance changes over time.

Method

This was a retrospective cohort study evaluating dysphagia patients’ clinical course by serial videofluoroscopic swallow study. Univariate analysis followed by multivariate analysis were used to identify correlations between pneumonia outcomes, diet allocation, aetiology and comorbidities.

Results

This study identified 104 patients (53 per cent male) stratified into risk groups by penetration-aspiration scale scores. Mean penetration-aspiration scale worsened over time (p < 0.05), but development of pneumonia was not associated with worsened penetration-aspiration scale score over time (p = 0.57) or severity of dysphagia (p = 0.88).

Conclusion

Our dataset identified a large cohort of patients with oropharyngeal dysphagia and demonstrated mean penetration-aspiration scale tendency to worsen. Identifying prognostic factors associated with worsening radiological findings and applying this to patients at risk of clinical swallowing difficulty is needed.
