Pharyngeal residue and penetration\u2013aspiration are key impairments associated with dysphagia in this population, yet their relationship across different bolus consistencies and volumes remains incompletely understood. The clinical role of patient\u2010reported outcome measures, such as the Eating Assessment Tool\u201010 (EAT\u201010), in relation to instrumental swallowing findings also requires further investigation. This study aimed (1) to examine the relationship between pharyngeal residue and penetration\u2013aspiration across different bolus consistencies and volumes in IwIPD, and (2) to evaluate the discriminative performance of the EAT\u201010 against FEES findings related to these swallowing impairments.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Ninety\u2010seven IwIPD were included. Participants completed the EAT\u201010 and underwent Flexible Endoscopic Evaluation of Swallowing (FEES). Ten swallowing trials were conducted using boluses of varying consistencies and volumes prepared according to the International Dysphagia Diet Standardisation Initiative (IDDSI). FEES recordings were independently rated by three clinicians using the Penetration\u2013Aspiration Scale (PAS) and the Yale Pharyngeal Residue Severity Rating Scale (YPRSRS).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Larger bolus volumes were associated with higher residue severity and PAS scores across planned within\u2010consistency comparisons. Significant correlations were observed between PAS scores and both EAT\u201010 and YPRSRS scores across consistencies and volumes (\n                      <jats:italic>\u03c1<\/jats:italic>\n                      = 0.56\u20130.91,\n                      <jats:italic>p<\/jats:italic>\n                      &lt; 0.01). The EAT\u201010 showed discriminative performance against FEES findings related to pharyngeal residue, penetration, and aspiration across swallowing trials. Interrater reliability for YPRSRS and PAS ratings ranged from 0.58 to 0.87.

EAT\u201010 scores showed discriminative performance against FEES findings; however, the EAT\u201010 should be interpreted as a patient\u2010reported screening measure rather than a diagnostic test for physiological swallowing impairment.

Bolus consistency and volume are known to influence swallowing performance. Patient\u2010reported outcome measures, such as the Eating Assessment Tool\u201010 (EAT\u201010), are widely used in dysphagia screening, but they cannot replace instrumental swallowing assessment.<\/jats:p>\n                        <\/jats:list-item>\n                      <\/jats:list>\n                    <\/jats:p>\n                    <jats:p>\n                      <jats:italic>What this study adds to existing knowledge<\/jats:italic>\n                      <jats:list list-type=\"bullet\">\n                        <jats:list-item>\n                          <jats:p>This study demonstrates a strong relationship between pharyngeal residue severity and penetration\u2013aspiration across different IDDSI\u2010defined bolus consistencies and volumes in IwIPD. The findings show that larger bolus volumes were associated with greater pharyngeal residue severity and higher PAS scores, while swallowing outcomes varied across consistencies and anatomical residue sites. The study also shows that EAT\u201010 scores demonstrated discriminative performance against FEES findings related to pharyngeal residue, penetration, and aspiration, while highlighting the need for cautious interpretation of EAT\u201010 cut\u2010off values in this population.<\/jats:p>\n                        <\/jats:list-item>\n                      <\/jats:list>\n                    <\/jats:p>\n                    <jats:p>\n                      <jats:italic>What are the potential or actual clinical implications of this study?<\/jats:italic>\n                      <jats:list list-type=\"bullet\">\n                        <jats:list-item>\n                          <jats:p>The findings support the importance of evaluating both swallowing safety and swallowing efficiency during instrumental assessment in IwIPD.
