Thicker is better? Impact of food consistencies on aspiration detection using IDDSI levels.

Background/purpose: Water is the most commonly, and often the only tested material in swallow screening. Our objective is to assess the impact of food consistencies on the reliability of trial swallows in predicting aspiration in dysphagic patients, utilizing the International Dysphagia Diet Standardisation Initiative (IDDSI) levels.

Methods: All trial swallows were evaluated using 5 ml of standardized test food with IDDSI levels of 0, 2, 4, 5.

The standardizing texture of thickened barium stimuli in the videofluoroscopic swallowing study at a medical center in Taiwan.

This study aimed to establish more practical standardized barium stimuli formulas for the videofluoroscopic swallowing study (VFSS) for clinical use. For clinical practice, we established the formula for preparing barium stimuli to comply with different International Dysphagia Diet Standardization Initiative (IDDSI) levels. To comply with the definition of IDDSI levels 0-4, the gum-based thickener concentration of thickened barium was 0, 0.
