Updated Statement of Problem

A modified barium swallow study "MBS", which is effective at ruling out silent aspiration in dementia patients, is difficult to perform for surgical patients and patients with severe wounds who lack mobility. An MBS can only be performed at the radiology department, as a consequence difficulties arises due to mobility issues. Therefore, it is essential to investigate the percentage of silent aspiration with dementia patients to determine whether an MBS is a needed assessment tool for this population.
