Abstract
Background: PSQ has sensitivity of 0.85 and specificity of 0.87 in otherwise well children aged 2-18 for identifying SDB confirmed by polysomnography (PSG) 1 . Applicability of PSQ in chronic conditions is unclear; we hypothesise it is a valid tool in this group. Methods: We retrospectively reviewed PSQs and PSGs (n=157). PSQ sensitivity and specificity was calculated. Apnoea-hypopnea index (AHI) of ≥5 and PSQ score >0.33 were indicative of SDB 1 . Results: Conclusions: We confirm PSQ is a sensitive screening tool in healthy children with OSA symptoms. PSQ is less useful in chronic illness where aetiology of SDB is more likely multifactorial. Prospective data collection to elucidate applicability of PSQ in other groups (metabolic, cardiac and spinal patients) is ongoing. 1 Chervin R et al. Sleep Med 2000;1:21-32.
