Quality of life in oropharyngeal dysphagia patients, measured by SWAL-QOL and SWAL-CARE, is modestly linked to bolus flow. Worse bolus flow correlates with poorer quality of life, highlighting the need for combined assessments.

Area of Science:

  • Otorhinolaryngology
  • Gastroenterology
  • Speech-Language Pathology

Background:

  • Oropharyngeal dysphagia significantly impacts patient quality of life.
  • Quantifying the relationship between patient-reported outcomes and objective swallowing measures is crucial for effective treatment.
  • Existing research often focuses on either quality of life or physiological measures independently.

Purpose of the Study:

  • To quantify the association between dysphagia-specific quality of life (SWAL-QOL) and quality of care (SWAL-CARE) scores and objective bolus flow measures.
  • To determine which bolus flow parameters are most strongly correlated with patient-reported outcomes in oropharyngeal dysphagia.
  • To explore the complementary roles of patient-centered and clinician-driven assessments in dysphagia research.

Main Methods:

Related Experiment Videos

  • 386 individuals with oropharyngeal dysphagia underwent videofluoroscopic swallowing examinations.
  • Participants completed the SWAL-QOL and SWAL-CARE questionnaires.
  • Bolus flow patterns were analyzed from videofluoroscopic recordings and correlated with SWAL-QOL and SWAL-CARE scores.

Main Results:

  • SWAL-QOL and SWAL-CARE scores showed modest correlations with four bolus flow measures.
  • Oral transit duration and total swallow duration exhibited the strongest relationships with quality of life scores.
  • Relationships were generally weaker for liquid trials compared to semisolid trials and for the Penetration Aspiration Scale.

Conclusions:

  • Patient-centered quality of life measures (SWAL-QOL, SWAL-CARE) and clinician-driven bolus flow measures offer distinct yet complementary information in oropharyngeal dysphagia.
  • Worse bolus flow severity is associated with a poorer quality of life.
  • Both types of measures are recommended for use in dysphagia effectiveness and outcomes research.
