Screening tools to identify children with obstructive sleep apnea (OSA) are needed. Video clips and Pediatric Sleep Questionnaire (PSQ) may assist with triage. Pandemic limited access to pediatric polysomnography but home polygraphy was available. Our aim was to evaluate the association between home-recorded mobile video clips with 1) polygraphy measures and 2) PSQ, in otherwise healthy children referred for OSA evaluation. Three video clips during sleep were scored by two independent blind clinicians, using the Monash Score (?3 consistent with OSA). Children completed PSQ and underwent polygraphy (Nox 3 Respiratory Portable Sleep Recorder, Nox Medical, Iceland). OAHI ?1.5/hour, ODI3% (desaturation index) ?4.3/hour and/or PSQ >0.33 were considered indicative of OSA. Sensitivity and specificity of video clips and PSQ scores for OSA on polygraphy were assessed. 26 children were included (mean age 6.5 years, BMI 37.7 kg/m2, 62% male, 38% with OSA). Mean (SD) OAHI was 4.5±12.9 /hour and ODI3% was 7.4±13.0/hour. PSQ score, Monash score and ODI3% indicated OSA in 81%, 31% and 39%, respectively. Video clip scores had sensitivity and specificity of 70% and 94% for each of OAHI? 1.5/hour and ODI? 4.3/hour. PSQ scores had sensitivity and specificity of 90% and 25%, respectively, for each of OAHI? 1.5/hour and ODI3% ?4.3/hour. Video clips had high specificity and good sensitivity, in contrast to the PSQ which had high sensitivity and low specificity for OSA on polygraphy. Future studies should consider a combination of screening tools.
