Accuracy of the volume-viscosity swallow test for clinical screening of oropharyngeal dysphagia and aspiration

Acurácia da avaliação clínica da disfagia orofaríngea na encefalopatia crônica não progressiva

“…Several screening and clinical assessment protocols for oropharyngeal dysphagia can be found In the current literature; however, the vast majority of studies are in post-stroke individuals [14][15][16][17][18] . As a consequence, we have not found studies on accuracy of clinical assessment of dysphagia in a population similar to this study, as the studies on oropharynge dysphagia in CP, in the most part, characterizes the profile of swallowing in this population 19 .…”

Effects of Posture on Subjective Swallowing Difficulty during Screening Tests for Dysphagia

“…The water-swallowing test was scored one for inability to swallow through to five for complete swallowing. Similarly, in the food-swallowing test, severe food aspiration was scored as one, with relative scores up to five, which was scored when there was no sings of aspiration: cough or voice changes or both were considered signs of potential aspiration [16,17]. Besides, during the repetitive saliva-swallowing test, the number of swallows was recorded.…”

Oral Hygiene, Aspiration, and Aspiration Pneumonia: From Pathophysiology to Therapeutic Strategies

“…The V-VST is a bedside clinical method which uses different volumes (5, 10, or 20 mL) and viscosities (nectar, liquid, and pudding) administered in a progression of increasing difficulty to protect the patient from aspirations. It combines the use of pulsioximetry to detect silent aspirations and is easy, cheap, and reliable (88.2 % sensitivity for impaired safety, 100 % sensitivity for aspirations, and 64.7 % specificity) [20]. If OD is diagnosed as severe, a second evaluation with videofluoroscopy, the gold standard, is performed using the same progression of boluses as were used in the V-VST, to assess swallowing alterations.…”

“…The intervention protocol is being introduced into the main hospital units treating elderly patients at risk of OD (geriatric and neurological units). This intervention consists of screening for OD using the V-VST [20] on admission and discharge, evaluating nutritional status using the MNA-SF [21] and assessing oral health and oral hygiene status with the OHI-S [22] and the presence of periodontal diseases and dental caries. The V-VST is a bedside clinical method which uses different volumes (5, 10, or 20 mL) and viscosities (nectar, liquid, and pudding) administered in a progression of increasing difficulty to protect the patient from aspirations.…”
