Dysphagia Cost
Studies show dysphagia significantly increases healthcare costs, adding roughly 30% to 40% more to inpatient hospital expenses per admission. Dysphagia extends hospital stays by an average of 2 to 4 days and can lead to costly complications like aspiration pneumonia, averaging around $17,000 per episode of care.

Value of FEES Imaging
Studies show that FEES exams completed in the post-acute care setting demonstrate significant improvement in diet levels, lower rates of pneumonia, and improved outcomes measures.

Importance of Instrumentals
The direct visualization of anatomy and physiology during FEES allows for assessment of tissue and muscle function, anatomical variants and abnormalities, and provides insight into the true etiology for dysphagia.

Comfort and Safety of FEES
FEES has proven to be a safe and well tolerated method of assessing swallow function when performed by a trained Speech Pathologist. The rate of complications associated with FEES is less than 1% overall.

FEES and MBSS
Studies show there is a good agreement between MBSS and FEES when examining premature spillage, pharyngeal residue, laryngeal penetration, and tracheal aspiration. FEES has proven to be as sensitive, or more sensitive, than MBSS relative to standard swallowing parameters.
