简要总结
The purpose of this study is to assess whether eye-tracking technology can be used to differentiate the visual gaze patterns of experienced and novice laryngoscopists while reviewing prerecorded laryngeal videos with both normal and abnormal findings and to characterize any differences arising between level of training groups.
详细描述
Novice and experienced participants will be recruited to take part in this study. Novices include medical students without practical experience in otorhinolaryngology and resident physicians at different stages in training. Trainees, residents and experts from fields of gastroenterology and pulmonology will also be included. The experienced group will be defined as consultants and speech pathologists.
This study will look at multiple areas within otolaryngology including laryngology, rhinology, facial plastic surgery, head and neck oncology, and otology. Participants will view prerecorded videos and/or still pictures absent of patient identifiers.
There will be two tasks each taking approximately 10 minutes. Task order will be alternated between subjects with one task asking participants to view 7 still images from video laryngoscopy examinations. After each image participants will rate how likely the image is to represent glottic cancer and what portion of the image they deemed most important to their decision. For the second task, participants will be asked to view a 5 second video of a flexible laryngoscope exam, after which, they will be asked to identify the presence and side of vocal fold paralysis as well as note the location they deemed most important to their decision.
