Key takeaways:
- Polysomnography use is commonly restricted for kids, leaving a necessity for various diagnostic OSA exams.

HONOLULU — Video clips of kids might help in screening for obstructive sleep apnea, as this technique was almost as efficient in detecting OSA in contrast with different instruments, in accordance with two research offered on the CHEST Annual Assembly.
“There’s an actual scarcity for diagnostic exams which might be obtainable, notably polysomnography, for kids with obstructive sleep apnea,” Sherri L. Katz, MDCM, MSc, FRCPC, FCCP, chief of pediatric respirology at Kids’s Hospital of Jap Ontario, instructed Healio. “We have to do higher at figuring out which youngsters actually need a sleep research and ensuring that those that have OSA get early and fast entry to diagnostic exams.”
Katz and Refika ErsuMD, director of the sleep laboratory and residential air flow program at Kids’s Hospital of Jap Ontario, offered two complementary research concerning using brief video clips, recorded by dad and mom, to find out which youngsters want polysomnography to diagnose OSA.
Within the first research, which included 50 youngsters (imply age, 7.6 years; 46% boys) aged 3 to 18 years, dad and mom had been instructed to document three brief video clips utilizing their smartphones, which had been then reviewed by two impartial clinicians for indicators of OSA utilizing each the Monash Obstructive Sleep Apnea Video Rating and total clinician impression of presence and severity of OSA. Interrater settlement and settlement between the 2 scores had been then estimated utilizing weighted Cohen’s kappa.
With scores of three or increased indicating OSA, the imply Monash rating was 3.25 and 32% of sufferers had a constructive medical impression of OSA.
Settlement between clinicians for the Monash rating was 0.911 for the presence of OSA and 0.955 for severity (P < .001 for each). Settlement for medical impression was 0.908 for presence and 0.812 for severity (P < .001 for each).
“The inter-relatability was wonderful. Two raters got here up with the identical conclusions about whether or not a toddler is more likely to have OSA or not based mostly on the video clips,” Katz mentioned. “The following step was to then examine it to different diagnostic exams that exist for sleep apnea.”
The second research, offered by Ersu, evaluated how the video clips in contrast with polygraphy measures, oximetry and the Pediatric Sleep Questionnaire (PSQ).
Researchers thought-about the affected person to have OSA with scores of greater than 1.5 on the obstructive apnea-hypopnea index (oAHI), 4.3 or increased per hour on the oxygen period index 3% (ODI3%), 2 or increased on McGill oximetry rating, 3 or increased utilizing Monash rating, and/or better than 0.33 on the PSQ.
Of the 38 sufferers (imply age, 6.8 years; 17 ladies) included, OSA was indicated in 35 (92.1%) utilizing PSQ rating, 18 (47.4%) utilizing Monash rating, 14 (36.8%) utilizing ODI3% and 6 (15.8%) utilizing the McGill rating.
Thus, with a sensitivity of 75% and specificity of 85% at a 1.5 oAHI threshold, the video clips confirmed higher diagnostic traits than PSQ and related traits in contrast with oximetry.
“It was profitable in diagnosing obstructive sleep apnea, extra so than only a easy questionnaire,” Ersu instructed Healio. “It carried out lower than oximetry however requires much less useful resource in restricted settings.”
The usage of smartphone movies wants further research for this capability, however such an method may very well be helpful when extra examined strategies are unavailable.
“Due to the restrictions for what’s on the market, it’s laborious for folks to entry [sleep studies] and there are geographic and different disparities that restrict entry to testing, so we’d like one thing that’s easy, that oldsters can do at house and that’s obtainable for everyone,” Katz mentioned.
It’s “slightly widespread” to see OSA in in any other case wholesome youngsters, in accordance with Ersu.
“[It’s] extra widespread if they’ve weight problems or medical complexity and in youngsters who reside in low socioeconomic standing and a few minority youngsters,” Ersu added. “There are opposed penalties, so if it’s identified well timed and handled well timed, there could also be numerous well being advantages.”
