Brief summary
This study aims to see if mobile video clips (smartphone recordings) can be used to screen children with Down syndrome to identify those at highest risk of obstructive sleep apnea (OSA), so they can be prioritized for an earlier sleep study. Parents will be asked to record short video clips of their child sleeping, and then rate whether they think their child has OSA. Later, children will undergo a sleep study to compare to the ratings.
Detailed description
Children with Down syndrome have approximately a 50% chance of developing obstructive sleep apnea (OSA) in their lifetime. OSA is a serious condition where a person stops breathing periodically during sleep; it is associated with high blood pressure, behavioural issues, and lower quality of life. Early diagnosis and treatment is critical, but the best way to diagnose OSA, a 'sleep study', is in short supply. Given the limited resources, this study aims to see if mobile video clips (smartphone recordings) can be used to screen children with Down syndrome to identify those at highest risk of OSA, so they can be prioritized for an earlier sleep study. Parents of children with Down syndrome, recruited from clinic, will be asked to record short video clips of their child sleeping. Parents will independently rate whether they think their child has OSA and how severe it is, based on the videos, as will two clinicians. Parents will also watch an educational webinar and be asked to re-rate the presence and severity of OSA in their child, to see if the webinar improves their accuracy. Finally, children will undergo a sleep study to compare to the ratings. This study will help determine whether videos can be used to accurately screen for OSA in this high risk population, prioritizing children for earlier diagnosis and treatment.
Interventions
DIAGNOSTIC_TESTVideo clip assessment
Parents will take short video clips of their child sleeping at night. They will be asked to review the video clips and rate whether they think their child has obstructive sleep apnea (OSA), and if so, how severe it is. Two clinicians will review the video clips on a separate night.
DIAGNOSTIC_TESTPolysomnography (sleep study)
Children will undergo a polysomnography as the gold standard test to assess for OSA.
OTHEREducational webinar
After evaluating the video clips of their child sleeping, parents will watch an educational webinar on OSA in children with Down syndrome and how to recognize symptoms.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Parental screening assessment of presence/absence of OSA based on homemade video clip | 1 day | Questionnaire developed at CHEO by Pediatric Respirologists and Otolaryngologists. The question of interest is "Do you think your child has obstructive sleep apnea?" The reviewer (a parent) will choose 'Yes' or 'No' after reviewing the homemade video clips. This is a dichotomous outcome with 'Yes' considered as the highest score. The gold standard reference test will be a polysomnography. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Parental assessment of severity of OSA based on homemade video clip | 1 day | Questionnaire developed at CHEO by Pediatric Respirologists and Otolaryngologists. The question of interest is "Do you believe the severity of the obstructive sleep apnea is: a) Mild, b) Moderate, or c) Severe ?" This question will only appear to parents who chose 'Yes' for the primary outcome. The reviewer will answer the question after reviewing the homemade video clips. This is an ordinal outcome with 'Mild' being considered the lowest score (1), and 'Severe' being considered the highest score (3). The gold standard reference test will be a polysomnography. |
