Oh, brace yourselves, folks! We’ve got a real game-changer here: the Group for Learning Useful and Performant Swallowing (GLUPS), because apparently, we needed another acronym in the medical world. This shiny new tool is here to revolutionize the way we look at people swallowing on X-ray videos, also known as the videofluoroscopy swallowing study (VFSS).
So, what did our intrepid researchers do? They gathered 45 brave souls from the bustling corridors of the University Hospital Saint-Pierre in Brussels, who probably had nothing better to do than to get their swallowing filmed and analyzed. These participants were split into a gripping drama of 24 patients and 21 controls, all ready for their close-ups.
The VFSS footage was then rated with the GLUPS tool by two otolaryngologists and a speech therapist, who were all blind to the purpose. I mean, not literally blind, because that would make rating the videos rather difficult, but they didn’t know who was who. And because consistency is key, they did it all over again within a week to make sure they weren’t just making wild guesses.
Now, hold onto your hats: the internal consistency was α = 0.745, which is, you know, adequately consistent. The test-retest reliability was through the roof with rs = 0.941 (p = 0.001), suggesting that maybe, just maybe, they were onto something. And, because we all love external validation, GLUPS was in cahoots with the Penetration-Aspiration Scale, showing a significant correlation (rs = 0.551; p = 0.001).
But wait, there’s more! The GLUPS score was significantly higher in patients than in controls (6.21 ± 4.42 vs. 2.09 ± 2.00; p = 0.001), which is a relief because it would be awkward if it were the other way around. And the interrater reliability? No significant differences, because our judges were apparently in perfect harmony.
For those without any VFSS abnormalities, the mean GLUPS score was a whopping 2.09 out of 23, setting the bar high with a score of ≥3.0 being the red flag for a pathological VFSS.
In conclusion, GLUPS is not just a fun word to say, but also a clinical instrument that documents the abnormal findings of oral and pharyngeal phases at the VFSS with high reliability and excellent criterion-based validity. It’s ready for its clinical practice debut, so let’s roll out the red carpet for GLUPS, the latest star in the swallowing evaluation show! 🌟
