Swallowing Impairment and Aspiration Risk in Patients After Acute Respiratory Events

101 patients hospitalized for pneumonia or acute respiratory failure underwent videofluoroscopic swallowing studies after clinical stabilization. The data includes Penetration–Aspiration Scale scores and predictors of aspiration risk, with a specific focus on COPD patients. Anna Annunziata published the dataset on figshare under a CC-BY-4.0 license.

Use Cases

• Predict aspiration risk based on clinical, functional, and anatomical predictors mentioned in the description.
• Analyze the relationship between airway invasion severity and pharyngeal residue patterns described in the results.
• Build a Random Forest model for discriminating aspiration risk, as referenced in the methodology.
• Identify key predictors of aspiration within the COPD subgroup, as highlighted in the study.

Strengths

• Includes 101 patient records with detailed clinical and swallowing assessment data.
• Machine-learning analysis achieved good discrimination with an AUC of 0.90.
• Provides specific insights for a COPD subgroup, with nearly half of COPD patients falling within PAS 6–8.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal or source bias inherent to a single retrospective study.
