ABSTRACT
Objective@#To compare the findings of videofluoroscopic swallowing study (VFSS) in patients with stroke-associated pneumonia (SAP). @*Methods@#Between January 2015 and June 2019, 1245 patients diagnosed with pneumonia underwent VFSS examination. Data were collected through retrospective chart reviews. Depending on the diagnosis, 378 post-stroke patients identified were classified into two groups: 327 non-aspiration pneumonia (non-AP) and 51 aspiration pneumonia (AP). Aspiration pneumonia was diagnosed both clinically and radiologically. VFSS results included 11 items of functional dysphagia scoring (FDS) and 8 points of penetration-aspiration scale (PAS) that analyze the swallowing function by anatomical site. @*Results@#Based on the FDS score, the AP group showed significantly higher values in residue in pyriform sinuses (P= 0.01), as compared to the non-AP group. There was a significant difference in the PAS score between both groups (P＜0.001). @*Conclusion@#Based on the FDS results, AP in SAP is associated with residue in piriform sinuses. VFSS tests therefore have the potential to be clinically applied to predict the occurrence of aspiration pneumonia in stroke patients.
