“…Furthermore, the diet recommendations are not classified according to the International Dysphagia Diet Standardisation Initiative (IDDSI), which makes a transfer to international diet management systems difficult. Recently, a bedside evaluation of swallowing function showed good accuracy to detect PED in critically ill patients after extubation [ 34 ]. However, this screening has been validated on physiotherapists and does not evaluate bolus swallows.…”

“…Therefore an easy-to-use, standardized bedside dysphagia screening tool, such as the GUSS-ICU, would allow ICU nurses to perform a systematic testing for dysphagia in the absence of dysphagia experts and/or instrumental swallowing evaluations. A recent study showed, that the FEES was not performed in 56% of critically ill patients after extubation because of the unavailability of FEES operators [ 34 ]. So far, the GUSS-ICU has not been validated for nurses in the ICU, but the original GUSS has been validated and successfully used by nurses in stroke patients [ 16 , 35 ].…”

Purpose Screening for dysphagia at the intensive care unit (ICU) soon after extubation can prevent aspiration, pneumonia, lower mortality, and shorten re-feeding interval. This study aimed to modify the Gugging Swallowing Screen (GUSS), which was developed for acute stroke patients, and to validate it for extubated patients in the ICU. Methods In this prospective study, forty-five patients who had been intubated for at least 24 h were recruited consecutively at the earliest 24 h after extubation. The modified GUSS-ICU was performed twice by two speech and language therapists independently. Concurrently, gold standard the flexible endoscopic evaluation of swallowing (FEES) was performed by an otorhinolaryngologist. Measurements were conducted within a three-hour period; all testers were blinded to each other’s results. Results According to FEES, 36 of 45 (80%) participants were diagnosed with dysphagia; 13 of those were severe, 12 moderate, and 11 mild. Compared to FEES, the GUSS-ICU predicted dysphagia well (area under the curve for the initial rater pair: 0.923, 95% CI 0.832–1.000 and 0.923, 95% CI 0.836 -1.000 for the second rater pair). The sensitivity was 91.7% (95% CI 77.5–98.3%) and 94.4% (95% CI 81.3–99.3%); the specificity was 88.9% (51.8–99.7%) and 66.7% (29.9–92.5%); the positive predictive values were 97.1% (83.8–99.5%) and 91.9% (81.7–96.6%), and the negative predictive values were 72.7% (46.8–89%) and 75% (41.9–92.6%) for the first and second rater pairs, respectively. Dysphagia severity classification according to FEES and GUSS-ICU correlated strongly (Spearman’s rho: 0.61 for rater 1 and 0.60 for rater 2, p < 0.001). Agreement by all testers was good (Krippendorffs Alpha: 0.73). The interrater reliability showed good agreement (Cohen`s Kappa: 0.84, p < 0.001). Conclusion The GUSS-ICU is a simple, reliable, and valid multi-consistency bedside swallowing screen to identify post-extubation dysphagia at the ICU. Trial registration ClinicalTrials.gov Identifier: NCT04532398,31/08/2020.
