Abstract
STUDY OBJECTIVES: (1) To assess the predictors for obtaining polysomnography (PSG) in children undergoing adenotonsillectomy (AT) for sleep-disordered breathing, and (2) to estimate the adherence to the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) guideline recommendations for pre-AT PSG. METHODS: This was a retrospective cohort study of children who were seen in the Pediatric Otolaryngology Clinic and underwent AT for sleep-disordered breathing over a 13-month period at a single tertiary care children's hospital. Patients with and without pre-AT PSG were compared using bivariate and logistic regression analysis to identify predictors for PSG. Electronic medical records were reviewed for demographic variables, medical comorbidities, and PSG data. Adherence to AAO-HNS guideline recommendations was estimated by calculating the proportion of patients who had a PSG among those who met the recommended criteria for pre-AT PSG. RESULTS: Mean age was 6.6 ± 3.6 years with 53% male. A total of 65 of 324 children (20%) underwent PSG prior to AT. The only factor significantly associated with pre-AT PSG was age 1 to 3 years (odds ratio 4.5, 95% confidence interval [2.2, 9.0], P < .001). Among patients who met AAO-HNS criteria for pre-AT PSG, 28 of 128 (20%) underwent PSG compared to 35 of 186 (19%) who did not meet criteria (odds ratio 1.0, 95% confidence interval [0.6, 1.9], P = .87). CONCLUSIONS: Among children who underwent AT, the only significant predictor of obtaining pre-AT PSG was age 1 to 3 years. The rate of adherence to the AAO-HNS guideline recommendations was low (20%), which represents an educational opportunity.
