P029 Home video sleep recording as a screening tool for paediatric obstructive sleep apnoea

INTRODUCTION: Polysomnography (PSG) remains gold standard for assessment of paediatric OSA, despite limitations. Home-based video sleep recordings offer a promising screening tool that would be relatively simple and inexpensive but have been minimally investigated. This study aims to assess the ability of short home-based video sleep recordings to predict PSG-diagnosed OSA in a population of healthy children. METHODS: Healthy children aged 1–18 years undergoing PSG to assess for OSA were recruited. Those with comorbidities likely to cause/exacerbate OSA, aside from adenotonsillar hypertrophy and obesity, were excluded. Thirty-minute video recordings of sleep shortly after sleep onset capturing the face and exposed torso were obtained. A previously validated scoring system was modified to include six parameters: snore, inspiratory noise, respiratory events, respiratory effort, mouth breathing and neck extension. RESULTS: We report interim results of this ongoing study. Of the 51 children meeting inclusion criteria, videos for 44 (28M, mean (SD) age 8.58 (2.96) years) were deemed satisfactory and analysed. Four (9%) children had OAHI >5 episodes/h on PSG and median Total Video Score (TVS) was 0 (IQR 0–1). TVS and OAHI >5 episodes/h on PSG showed a statistically significant association (OR 2.782, p=0.006) with area under the curve of 0.847. TVS ≥4 showed sensitivity of 75% and specificity of 100% for OAHI >5 episodes/h. DISCUSSION: This video scoring system, when applied to short home-based video sleep recordings, showed acceptable diagnostic accuracy for PSG-diagnosed OSA. Full data analysis will further clarify the role of this modality as a screening tool for paediatric OSA.
