Abstract
Objective
Flexible endoscopic evaluation of swallowing (FEES) is widely performed to determine
the safety of oral intake. However, evaluation results can vary among examiners depending
on their experience. To analyze the impact of such differences, we investigated the
diet provided for patients with swallowing impairment evaluated by experienced and
inexperienced examiners.
Methods
We included 20 subjects with swallowing impairment. They underwent FEES twice, once
by an experienced examiner (EE) and once by an inexperienced examiner (IE), in random
order. The second FEES was generally performed within one month of the first FEES.
The diet provided by the EE (EE results) and by the IE (IE results) during and after
FEES was investigated and statistically compared. Respiratory and oral intake conditions
at each time of FEES were also investigated and the results were included in the corresponding
EE or IE results.
Results
The median interval between FEES was 13.5 days. There was no significant difference
between the EE and IE results regarding swallowing impairment-related conditions,
such as amount of sputum suctioned, oral intake status, or prevalence of fever after
FEES. However, there was a significant difference in the texture-modified diet provided
after FEES: A close-to-normal diet was provided by the EE compared to the diet provided
by the IE.
Conclusion
This study demonstrated a difference in the provided diet for patients with swallowing
impairment between the examiners with different levels of experience. Our results
suggest that EEs may be able to safely recommend patients with swallowing impairment
have a close-to-normal diet.
