Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants between 6 months and 15 years of age will be recruited opportunistically at Telethon Weekend and NAIDOC community events. Study staff will obtained informed consent and collect a basic screening ear health history. A trained assistant or audiologist will use the HearScope otoscope attached to a smartphone device to take still images and short 10 second videos of the middle ear and a Titan middle ear analyser to do tympanometry (a test to measure the movement of the ear drum) of each ear. The results of these tests will be saved for later comparison and analysis by a blinded consultant. If the results are abnormal and clinically significant, an audiologist will provide the family with counselling and a GP referral. Participation in the project is expected to last approximately 10-15 minutes.

The sub-study will precede the main Ear Portal study, with the findings informing the otoscopic technique (image or videos) that will be used during the main study. Participants in the Ear Explorers sub-study will therefore be recruited independently to the main Ear Portal study and form a separate cohort. They will only complete the Ear Explorers one-off visit and data collection.

Outcomes
Primary outcome [1] 321160 0
Clinician-rated overall quality of still image otoscopy compared to video otoscopy. The clinician will score aspects including image quality, image focus, light, cerumen, field of view and an overall quality assessment on 5-point scales.
Timepoint [1] 321160 0
Based on single day of image/video collection during attendance at community event
Secondary outcome [1] 374144 0
Ability to accurately diagnose middle ear effusion with still image otoscopy compared to video otoscopy. This will be assessed by the blinded clinician who will view the image and video in combination with the screening history and tympanometry result. They will provide an assessment on whether an accurate diagnosis can be made on the basis of the otoscopic views provided.

The sample size is anticipated to be between 300-400 participants and is based on the track record of previous projects hosted at the Telethon Weekend community event. Data will be analysed/reported using descriptive statistics. The overall ratings for still images and videos provided by the ENT/Audiologist will be compared using an independent t-test.
