Use of the sleep clinical record in the follow-up of children with obstructive sleep apnea (OSA) after treatment.

PURPOSE: The aim of our study was to evaluate the utility of the sleep clinical record (SCR) in the follow-up of children with obstructive sleep apnea (OSA) after treatment.

METHODS

SCR was completed and overnight polysomnography (PSG) was performed in all enrolled children (T0), with SCR considered positive for scores ≥6.5, as previously validated. Patients underwent adenotonsillectomy (T&A), rapid maxillary expansion (RME), and medical therapy according to severity of OSA and clinical features. Six months after completing therapy, the second overnight PSG and SCR (T1) were performed.

RESULTS

For all subjects, both Apnea-Hypopnea Index (AHI) and total SCR score decreased significantly (<0.005) from T0 to T1. For SCR items, clinical examination (item 1) and reported sleep respiratory symptoms (item 2) ameliorated significantly (<0.005). However, hyperactivity or inattention (item 3) decreased significantly (<0.005) after treatment only in T&A group, while no differences in AHI and SCR scores occurred in the medically treated group. At T1, SCR was positive in 95.6 % of children with AHI ≥1, with a concordance of 100 % in the T&A and RME groups, resulting in a positive predictive value of 100 %. A poor concordance (38.3 % in T&A group and 53.4 % in RME group) was found when SCR < 6.5. Children with SCR ≥ 6.5 at T1 showed higher AHI compared to patients with SCR < 6.5 (5.7 ± 5.9 ev/h vs 1.78 ± 1.76 ev/h; p < 0.005).

CONCLUSIONS

SCR emerges as a potentially useful instrument for follow-up of children with OSA after treatment.
