What are the 4 studies identified with sufficient methodological quality of screenings? Explain them.
Volume Viscosity Swallow Test (VVST)--3 viscosities/volumes via syringe, pulse oximetry, determine type of oral intake
Toronto Bedside Swallowing Screening Test (TOR-BSST)--OME screening, 10,1 tsp water pass/fail criteria, fail, refer to SLP, good reliability w/ training
3 oz water test: given by cup or straw w/o interruption, cough, choke, wet voice can't complete; good predictor of ability to tolerate thin but high false-positive rate; now referred to as Yale Swallow Protocol
Cough test: Inhale citric acid; physiologic salie orally via nebulizer; count coughs; limited sensitivity
