Pediatric sleep questionnaire predicts more severe sleep apnea in children with uncontrolled asthma.

OBJECTIVE: While up to 35% of children with asthma have evidence of sleep disordered breathing (SDB), it is unclear if nocturnal symptoms stem from asthma itself or SDB. The Pediatric Sleep Questionnaire (PSQ) is a validated tool for identifying SDB in childhood asthma. We hypothesize children with asthma and abnormal PSQ demonstrate decreased asthma control and are at higher risk of obstructive sleep apnea (OSA). METHODS: We performed a retrospective, chart review of children and young adults referred to our tertiary children's hospital severe asthma clinic. Data collection included age, gender, BMI percentile, spirometry, PSQ, asthma control questionnaires, asthma severity, control, and impairment. These data were evaluated in the context of polysomnography, when available. RESULTS: 205 inner-city children were included; 37.2% female, median age 6.4 y, and mean BMI of 71.3%ile. Rhinitis (p = 0.028), eczema (p = 0.002), and reflux (p = 0.046) were associated with abnormal PSQ; however, overweight/obese status, spirometry, asthma severity, and serologic markers were not. After correcting for comorbidities, abnormal PSQ score was associated with poor asthma control based on validated measures (p < 0.001). In patients with polysomnography, we confirmed abnormal PSQ was associated with increased OSA severity (apnea-hypopnea index 9.1/hr vs. 3.6/hr; p = 0.027). CONCLUSIONS: In pediatric asthma, positive PSQ was associated with significantly decreased asthma control. Additionally, children with normal PSQ demonstrated mild OSA, while children with abnormal PSQ had increased severity of OSA. This demonstrates that PSQ can be used to screen children for more severe sleep apnea.

Pediatric Quality-of-Life Scores Following a Multidisciplinary Aerodigestive Team Approach to Manage Chronic Cough.

OBJECTIVES: Chronic recalcitrant cough is present in 2/3 of pediatric patients evaluated in our tertiary-care multidisciplinary aerodigestive clinic (ADC). This study aimed to determine the impact of chronic cough and efficacy of ADC treatment using the validated Pediatric-Cough Quality-of-Life-27 tool (PC-QOL-27). METHODS: The PC-QOL-27 survey was administered to ADC patients with chronic cough at initial clinic visit and 6 to 12 weeks after cough management. Pre and post survey scores, demographic data, treatment and evaluation season were collected over 16 months. RESULTS: Twenty parents completed pre and post PC-QOL-27 surveys (mean 12.1 weeks later). Patient median age was 6.04 years (IQR: 2.2-10.44 years). A total of 65% were males and 65% were African American. Management was tailored based on clinical assessment and diagnostic studies, including direct laryngoscopy/bronchoscopy (4), pulmonary function tests (PFT's 9), esophagogastroduodenoscopy (9), and flexible bronchoscopy/lavage (9).Following ADC management, changes in physical, social and psychological domain scores of the PC-QOL-27 each met the threshold for minimal clinical important difference (MCID) indicating a clinically meaningful improvement. Improvements were most notable in the physical domain where post survey scores significantly improved from pre-survey scores (P = .009) regardless of age, gender, ethnicity, history of endoscopy and season. CONCLUSIONS: The physical impact of chronic cough in pediatric patients who failed prior management by a single specialist was lessened by an ADC team approach to management.
