Diagnostic method for dysphagia in the "chartevent" table

[Chenghongtao99]

Dear MIMIC-IV community members,

I am currently working on a study related to dysphagia. In my research, dysphagia is defined as a positive bedside swallowing screening result, which can be obtained from the "chartevents" table (itemid=225118). However, one of the reviewers of my work has raised a question regarding the diagnostic method for dysphagia, asking "What kind of assessment was done? This would be important for reproducibility and to understand the properties of the screen."

Could anyone provide more information on the assessment method used for the positive bedside swallowing screening results in the MIMIC-IV database? Any additional details regarding the assessment's reproducibility and properties would also be greatly appreciated.

Thank you in advance for your help and insights.
