Application of Viscosity Volume Screening Tool as a screening tool in swallowing disorders diagnosis

It is commonly known that dysphagia is associated with primary (malnutrition, dehydration, aspiration pneumonia) as well as secondary consequences (longer hospital stay, increased treatment cost, higher risk of mortality). Therefore screening tests in swallowing disorders, especially at risk groups are essential. The aim of screening is identification of patients at risk of dysphagia and referring patient to further instrumental methods. Test should be non invasive, quick, easy to perform by medical staff, with highest sensitivity and specifity. One of the test is Viscosity – Volume Screening Test (VVST) with 3 different consistencies at 3 volumes (5, 10 and 20 ml), what wider possibilities of these tool in safe consistency and volume indication.
