A Pilot Study of a Modified Swallowing Screening Tool for Critically Ill Patients in the Intensive Care Unit.

PMID 39601801WHAT IT FOUND
A modified bedside screening protocol combining ultrasound and specific dye tests allowed 13 ICU patients to safely resume oral feeding without aspiration symptoms.
This approach offers a feasible alternative to invasive endoscopy in isolation settings, though its accuracy remains unvalidated against gold-standard tests.
Key findings
01All patients who passed the modified screening evaluation started oral feeding without developing symptoms of aspiration and were discharged without dysphagia-induced complications.
02The screening tool successfully identified vocal cord abnormalities, with 4 of 12 tested patients having unilateral palsy and none having bilateral palsy.
03The study was limited by its small sample size and the lack of validation against gold-standard imaging like videofluoroscopy or endoscopy.

What it does not show
The study included only 13 patients, which is too small to establish reliability or generalizability. The screening tool was not compared against the gold-standard videofluoroscopic swallowing study (VFSS) or fiber-optic endoscopic evaluation of swallowing (FEES), so its true sensitivity and specificity are unknown. The study was conducted in a single center in Korea during the pandemic, which may limit applicability to other settings or patient populations. Vocal cord ultrasound proficiency requires significant training, and the accuracy of this component depends heavily on the examiner's skill.
Declared interests
The study was funded by the Bio&Medical Technology Development Program of the National Research Foundation (NRF) funded by the Korean government. No other conflicts of interest were declared.
The easy way to misread this
Do not assume this screening tool is as accurate as FEES or videofluoroscopy. It was never compared to these gold-standard tests, and the lack of observed aspiration in 13 patients does not prove it can reliably detect all cases of silent aspiration.
