This study evaluated whether or not polysomnography (PSG) inter-scorer reliability (ISR) across sleep centres could be improved by external proficiency testing (EPT), or by EPT combined with method al...
Experienced scorers form 15 sleep centres were randomised to the following: (1) a control group, (2) a group that received a self-directed intervention of EPT reports (EPT...
Among 30 scorers, there were no ISR changes in controls between baseline (BL) and 6 months (6 m). Both EPT groups showed ISR improvement from BL to 6 m for respiratory, arousal and sleep scoring (p < ...
External proficiency testing produced modest, statistically significant PSG inter-scorer reliability improvements among experienced scorers across sleep centres, with potential to improve clinical man...
Polysomnography (PSG) is the gold standard for the diagnosis of pediatric sleep-disordered breathing (SDB). However, the literature characterizing the indications for inpatient PSGs and the impact on ...
To determine the indications, results, and outcomes for children undergoing inpatient PSGs at our institution....
We performed a retrospective review of children aged 0-18 years who underwent inpatient diagnostic PSGs between July 2018 and July 2021 at SickKids, Toronto, Canada. Baseline characteristics, indicati...
Eighty-eight inpatient PSGs were performed in 75 children (male 62.7%). Median (interquartile range) age and body mass index z-score were 1.5 (0.2, 10.8) years and 0.27 (-1.58, 2.66), respectively. Th...
Our study highlights that inpatient PSG was an important diagnostic tool resulting in directed medical and surgical management. Future multicenter studies are needed to compare indications for inpatie...
The psychophysiological coherence model proposes that a heart rhythm pattern, known as heart rhythm coherence (HRC), is associated with dominant parasympathetic activity and the entrainment of respira...
To evaluate adherence to polysomnography in pediatric patients and determine if demographics, socioeconomic status, polysomnography indication, or prior otolaryngology intervention are associated with...
Retrospective review study....
Tertiary-care children's hospital....
Electronic medical record was queried to identify patients ordered for a sleep study between January and May 2019. Demographic information, time to sleep study, and time to surgery were collected and ...
304 patients were recommended to obtain polysomnography, with adherence rate of 65.4%. There was no significant difference in adherence or loss to follow-up rates based on patient sex, age, language, ...
Families with lower socioeconomic status or medically complex children may require assistance to obtain polysomnography and pursue surgery for sleep-disordered breathing. Patients without prior otolar...
The present study aimed to investigate the characteristics of salivary microbiota of children with obstructive sleep apnea (OSA) and to assess longitudinal alterations in salivary microbiota before an...
A set of cross-sectional samples consisted of 36 OSA children (17 boys and 19 girls, 7.47 ± 2.24 years old) and 22 controls (9 boys and 13 girls, 7.55 ± 2.48 years old) were included in the study, amo...
In cross-sectional samples, the OSA group had higher α-diversity as estimated by Chao1, Shannon, Simpson, Pielou_e, and observed species as compared with the control group (...
A significantly higher microbial diversity and a significant difference in microbial composition and abundance were identified in salivary microbiota of OSA children compared with controls. Meanwhile,...
Sleep deprivation is expected in the intensive care unit (ICU) and is associated with delirium and increased mortality. Polysomnography (PSG) is the gold standard for sleep assessment, but practical i...
We investigated the effect of growth and development level on polysomnography results in preschool children with obstructive sleep apnea (OSA)....
Preschool children (ages 3-6) with symptoms of snoring and were diagnosed with OSA by polysomnography in the sleep center were selected as the research object. They were split into three groups based ...
A total of 183 (111 boys and 72 girls) preschool children were enrolled. There were 26 cases in the growth restricted group, 112 cases in the normal growth group, and 45 cases in the overgrowth group....
OSA is more likely in preschool-aged children with stunted or overgrown growth than in children with OSA alone, and the more severe the disorder, especially when accompanied with stunted growth....
The gold standard test for diagnosis of sleep related breathing disorders (SRBD) in children is diagnostic polysomnography (PSG). This is often followed by a titration PSG to identify optimal non-inva...
This multi-center study analyzed clinical and PSG data from children with SRBD who had initiated NIV following a snPSG. Data from diagnostic and titration portions of the snPSG were analyzed separatel...
The study included 165 children who initiated NIV following a snPSG. The majority of children (61.8%) were initiated on NIV for upper airway obstruction. The population included children with medical ...
snPSG is technically feasible in children, facilitating the diagnosis of SRBD and initiation of NIV, even in those with high medical complexity....
The purpose of the study was to increase the body of knowledge related to sleep in children with autism. The specific aims were to (i) identify the subgroup of children with autism, ages 3-17 years, r...
The authors performed a secondary data analysis of the de-identified Nationwide Children's Hospital Sleep DataBank, a collection of encounters with children referred for polysomnography. The data were...
In the sample, there were 2838 unique participants (M = 10.5 years) with a total of 172 167 encounters between 2017 and 2019. Of these, 198 (7%) were diagnosed with Autism Spectrum Disorder, Asperger'...
Findings elucidate the increased presence of sleep problems in paediatric patients with autism, and the need for purposeful sleep evaluation and research given the potential impact on daytime function...
Severe obstructive sleep apnoea (OSA) is associated with increased risk of respiratory compromise in the post-operative period following adenotonsillectomy (AT). This study analyses the economic cost ...
This cost-minimisation analysis examines costs associated with pre-operative overnight oximetry and polysomnography in triaging paediatric patients older than 2 years old, with no major comorbidities ...
The total cost per patient of AT including pre-operative investigations of oximetry and polysomnography, and associated inpatient costs, were AUD4181.34 and 5013.99 respectively. This is more expensiv...
Within the scope of this partial economic evaluation, this study finds a small additional cost for a model of care involving overnight oximetry as a pre-operative triage tool, balanced by the reduced ...
