Quality of life and obstructive sleep apnea symptoms after pediatric adenotonsillectomy

Exploring the Association Between Pediatric Obstructive Sleep Apnea Severity and Quality of Life

OBJECTIVES

To investigate the relationship between pediatric obstructive sleep apnea (OSA) severity and quality of life (QOL).

STUDY DESIGN

This study was a cross-sectional survey.

METHODS

Patients aged 2-18 years being evaluated for OSA were recruited from a pediatric otolaryngology clinic and sleep center. Participants completed the Obstructive Sleep Apnea Questionnaire (OSA-18) and the PedsQL™ Multidimensional Fatigue Score (MFS).

RESULTS

Responses of 18 control participants without OSA, 26 participants with clinically resolved OSA, 19 with non-obstructive sleep disordered breathing (SDB), 29 with mild OSA, 21 with moderate OSA, and 27 with severe OSA were analyzed. OSA-18 scores for controls were lower (indicating higher QOL) than patients with SDB (mean difference [MD] = -31.1; 95% CI -42.7 to -19.5), mild OSA (MD = -30.4; 95% CI -40.1 to -20.7), moderate OSA (MD = -23.6; 95% CI -34.5 to -12.7), or severe OSA (MD = -40.1; 95% CI -50.0 to -30.2). Participants with resolved OSA also had lower OSA-18 scores than participants in the SDB and OSA groups. Few differences were observed between the SDB, mild OSA, moderate OSA, and severe OSA groups on either the OSA-18 or PedsQL MFS, and these did not demonstrate a clear pattern. Linear regression of apnea hypopnea index (AHI) and OSA-18 or PedsQL MFS scores revealed weak relationships (R2 < 0.1).

CONCLUSION

Using both an OSA-specific measure and generic fatigue measure, no consistent differences in QOL scores were found between children with varying OSA severities. Therefore, disease burden in pediatric patients with mild OSA and SDB should not be underestimated.

Adenotonsillectomy Versus Watchful Waiting for Children with Obstructive Sleep Apnea Syndrome: A Systematic Review with Meta-Analysis

The treatment of children with Obstructive Sleep Apnea Syndrome (OSAS) remains a point of debate among otorhinolaryngologists worldwide. This study aims to comparatively assess the clinical outcomes of adenotonsillectomy (ATE) and watchful waiting in children with OSAS. We searched the databases of PubMed, Scopus, and Cochrane Central Register of Controlled Trials (CENTRAL), until the 1st of October 2023. Comparative trials assessing the efficacy of adenotonsillectomy and watchful waiting in children with OSAS were considered. The primary outcome measure was the apnea-hypopnea index (AHI), and secondary outcomes included quality of life as measured by OSA-18 score, and mean SpO2 levels. A subgroup analysis evaluating the changes in AHI depending on the severity of the initial disease was also executed. We conducted a random-effects pairwise meta-analysis of change scores to include randomized and non-randomized controlled trials. The quality assessment was carried out by using the Cochrane risk of bias tool for randomized and the ROBINS-I tool for non-randomized trials, respectively. Two randomized and five non-randomized trials were included. There was a statistically significant difference regarding AHI in favor of the ATE group compared to the watchful waiting group (Standardized mean difference [SMD] was - 0.60, 95%CI -0.79 to -0.41, p < 0.001). Likewise, a statistically significant decrease in change scores for OSA-18 between ATE and watchful waiting was noted (SMD was - 0.79, 95%CI -0.97 to -0.61, p < 0.001). On the other hand, there was no significant difference when ATE and watchful waiting groups were compared for SpO2 levels between each other (SMD was 0.52, 95%CI -1.53 to 2.56, p < 0.62). In the subgroup analysis assessing mild OSAS, there was a significant difference in favor of ATE compared to watchful waiting (SMD was -0.91, 95%CI -1.35 to -0.47, p < 0.0001). For mild to moderate OSAS, similar results were noted favoring ATE as well (SMD was - 0.53, 95%CI -0.87 to -0.19, p < 0.003). This study provides evidence of moderate strength supporting the superiority of ATE over the watchful waiting approach in terms of AHI and OSA-18. This also appears to be the case for AHI in children with mild and mild to moderate OSAS.

Drug-Induced Sleep Endoscopy Predicts Subjective Outcomes of Adenotonsillectomy

OBJECTIVES

Persistent obstructive sleep apnea (OSA) after adenotonsillectomy (AT) has been reported in 20%-30% of children. The aim of this study was to determine the predictive value of drug-induced sleep endoscopy (DISE) at the time of AT on subjective AT outcomes.

METHODS

This was a prospective cohort study of children aged 2-18 years being treated with AT for sleep disordered breathing (SDB) with one or more risk factors for AT failure: age >7 years, obesity, severe baseline OSA, Black race. All underwent DISE at the time of AT. Potential predictors of subjective AT outcome included age, sex, obesity, and DISE patterns. Multivariable linear regression was used to model predictors of post-AT Pediatric Sleep Questionnaire (PSQ) and OSA-18 outcomes.

RESULTS

Pre- and post-AT PSQ/OSA-18 responses were available from 194 children. Mean age was 9.3 ± 3.5 years, with 59% obese, 50% female, and 67% White. After AT, mean PSQ score decreased from 0.60 ± 0.19 to 0.28 ± 0.22, p < 0.001 and mean OSA-18 score decreased from 66 ± 21 to 37 ± 18, p < 0.001. The most frequent sites of obstruction were the tonsils (92%), nasal airway (77%), adenoids (64%), and velopharynx (65%). Multivariable regression modeling demonstrated worse outcomes with obesity, male gender, and multilevel obstruction that included the nasal airway and tongue base in addition to adenotonsillar obstruction.

CONCLUSIONS

Persistent OSA and symptom burden after AT was common in this population. Obesity, male gender, and multilevel obstruction during DISE were all associated with worse subjective outcomes.

The Positive Effect of Adenotonsillectomy on Drooling in Children

OBJECTIVES

(1) To investigate the prevalence and severity of drooling among healthy young children referred for adenotonsillectomy; (2) to evaluate the effect of adenotonsillectomy on drooling.

STUDY DESIGN

Prospective study.

SETTING

Tertiary referral center.

METHODS

Healthy typically developed children aged 18 to 48 months referred to adenotonsillectomy for upper airway obstruction (UAO) were recruited. Age-matched children recruited from the community served as controls. Drooling frequency and severity were assessed at baseline and 2 months following surgery based on 2 subjective scales: the Drooling Infants and Preschoolers Scale (DRIPS) and Thomas-Stonell and Greenberg Saliva Severity Scale (TSGS).

RESULTS

Eighty-seven children aged 18 to 48 months were included in the study. Forty-three children referred to adenotonsillectomy (study group) and 44 age-matched controls. There were significant differences in almost all of the DRIPS items between children in the presurgery group compared to controls. Drooling severity and frequency were greater in the former compared to the latter (TGF-s severity: 1.4 ± 1.0 vs 0.6 ± 0.8, P = .001; TGF frequency: 1.3 ± 0.9 vs 0.5 ± 0.6, P < .001). After surgery, the scores for all DRIPS and TSGS items decreased significantly and were comparable to the control group.

CONCLUSIONS

The frequency and severity of drooling among otherwise young children referred for adenotonsillectomy were greater than those for healthy controls. Following surgery, both the frequency and severity significantly improved and became comparable to those of controls. These findings suggest that a major improvement in drooling is one of the benefits of a surgical intervention in a child with UAO.

Long-term effects of adenotonsillectomy in children with attention deficit hyperactivity disorder

STUDY OBJECTIVES

Adenotonsillectomy (AT) improves short-term symptoms of attention deficit hyperactivity disorder (ADHD) in children; however, its long-term effects remain unclear. We aimed to verify the therapeutic long-term effects of AT in children with ADHD.

METHODS

This retrospective control study included children ages < 18 years who were diagnosed with ADHD and receiving ADHD medications. Participants were divided into groups depending on whether AT was performed (AT [+] or AT [-] groups) and matched 1:1 for age, sex, and year and month of diagnosis using randomized nonreplacement selection.

RESULTS

Among patients with ADHD (n = 171,112), 3,615 underwent AT. In both groups, the number of drugs taken gradually increased before and decreased after the AT date (ATD). There was no difference in the number of drugs used before (P = .88) and after ATD (P = .06). Before ATD, the average number of outpatient visits (nOV) did not change in both groups (AT [+]: P = .12; AT [-]: P = .71). After ATD, the average number of outpatient visits decreased only in the AT (+) group (P = .001). However, there was no difference in the average number of outpatient visits between the two groups before (P = .47) and after ATD (P = .17). Before ATD, methylphenidate doses between the groups were not different (P = .06); however, a significant increase was noted after ATD in the AT (+) group (P < .001).

CONCLUSIONS

AT does not result in significant long-term therapeutic effects in terms of medication use and health care utilization in children with ADHD.

Malocclusions, Sleep Bruxism, and Obstructive Sleep Apnea Risk in Pediatric ADHD Patients: A Prospective Study

OBJECTIVES

Literature presents conflicting results regarding malocclusions, Obstructive Sleep Apnea (OSA) and sleep bruxism in children with ADHD. Aim of this study was to evaluate the prevalence of these parameters.

METHODS

A prospective study was conducted on 40 consecutive ADHD children referred to the Paediatric Dentistry Unit of Fondazione Policlinico Universitario "A. Gemelli" IRCCS, Rome. All subjects underwent an orthodontic examination and were screened for OSA and sleep bruxism. Data were compared to a sex- and aged-matched control group.

RESULTS

Prevalence of high risk of OSA in children with ADHD was 62.5% compared to 10% in the control group (p < .00001). No differences were found in any of the occlusal variables examined between children with ADHD and controls (p > .05). An increased prevalence of sleep bruxism was observed in ADHD children (40%) compared to controls (7.5%) (p < .001).

CONCLUSIONS

A higher prevalence of OSA risk and probable sleep bruxism were observed in ADHD patients compared with controls. No significant differences were observed in malocclusions d.

Changes in behavioral and cognitive abilities after rapid maxillary expansion in children affected by persistent snoring after long-term adenotonsillectomy: A noncontrolled study

INTRODUCTION

The objective of this study was to verify changes in behavioral abilities and cognitive functions after rapid maxillary expansion (RME) in children with refractory sleep-disordered breathing (SDB) in the long term after adenotonsillectomy.

METHODS

A prospective clinical trial study using RME therapy was conducted. Participant inclusion criteria were children who had adenotonsillectomy with maxillary transverse deficiency and persistent SDB (obstructive apnea-hypopnea index ≥1). The study included 24 children aged 5-12 years, and of these 24 children, 13 had primary snoring and 11 had obstructive sleep apnea. The patients underwent laryngeal nasofibroscopy and a complete polysomnography. In addition, patients completed the Obstructive Pediatric Sleep Questionnaire and Obstructive Sleep Apnea 18-Item Quality-of-Life Questionnaire. Behavioral and neurocognitive tests were also completed before and after RME.

RESULTS

The Obstructive Pediatric Sleep Questionnaire and Obstructive Sleep Apnea 18-Item Quality-of-Life scores showed a statistically significant decrease in both groups (P <0.001) after RME. The results showed that neurocognitive and behavioral parameters (Child Behavior Checklist scale) were similar in primary snoring and obstructive sleep apnea (OSA) groups before RME. In the OSA group, the mean scores of the "Somatic" and "Aggressiveness" domains decreased significantly (P <0.05). The cognitive functions did not register significant differences pre- and post-RME in any of the cognitive functions, except for visuospatial function in the OSA group.

CONCLUSIONS

The noncontrolled design was a major limitation of our study. The need for treatment for SDB should consider the association of symptoms and behavioral disturbances with the child's obstructive apnea-hypopnea index. RME might prove to be an alternative treatment for children with SDB refractory to adenotonsillectomy, improving quality of life and behavioral aspects. However, a larger sample size with a control group is needed to substantiate these claims.

Obstructive sleep related breathing disorders and cardiometabolic risk factors - A Portuguese birth cohort

BACKGROUND

Pediatric obstructive sleep related breathing disorders (SRBD) are an important under-diagnosed health problem with associated cardiometabolic comorbidities, demonstrated with polysomnographic studies in selected samples. Our main goal was to assess the prevalence of SRBD in a population-based cohort and to analyze its association with cardiometabolic risk factors, in general and by sex.

METHODS

Pediatric Sleep Questionnaire (PSQ) was applied to parents of 7-years-old children evaluated in the birth cohort, Generation XXI. Sex, anthropometrics, blood pressure (BP), lipid profile, glucose, insulin, HOMA-IR, and high-sensitivity C-reactive protein were compared among children with/without SRBD, using Chi-square, Mann-Whitney tests and logistic regression models.

RESULTS

A total of 1931 children (51.2 % boys) were included; 17.5 % were overweight and 15.7 % obese. The prevalence of SRBD was 13.4 %, more frequent among boys (15.7 % vs.10.9 %, p = 0.002) and in overweight/obese children (22.0 % vs.13.6 % vs.11.3 % in obese, overweight and normal weight group, respectively, p < 0.001). Children with SRBD had higher systolic BP (107 ± 8 vs.105±9 mmHg; p = 0.001) and lower HDL-cholesterol levels (54 ± 11 vs.56 ± 11 mg/dL; p = 0.04) than children without SRBD. After adjustment for sex, age, birthweight-for-gestational age and maternal age, children with SRBD had higher BMI-z-score, systolic BP, insulin and HOMA-IR levels, and lower HDL-cholesterol, when compared to those without SRBD, but these associations were lost when adjusting to BMI z-score. Analyzing obese children with the same regression model, those with SRBD presented lower HDL-cholesterol than those without SRBD.

CONCLUSIONS

Our results identified a male predominance of SRBD in pre-pubertal children and highlighted the potential contribution of SRBD to cardiovascular risk in obese children.

Management of Persistent, Post-adenotonsillectomy Obstructive Sleep Apnea in Children: An Official American Thoracic Society Clinical Practice Guideline

Background: Obstructive sleep apnea (OSA) is the most common sleep-related breathing disorder. Although adenotonsillectomy is first-line management for pediatric OSA, up to 40% of children may have persistent OSA. This document provides an evidence-based clinical practice guideline on the management of children with persistent OSA. The target audience is clinicians, including physicians, dentists, and allied health professionals, caring for children with OSA. Methods: A multidisciplinary international panel of experts was convened to determine key unanswered questions regarding the management of persistent pediatric OSA. We conducted a systematic review of the relevant literature. The Grading of Recommendations, Assessment, Development, and Evaluation approach was used to rate the quality of evidence and the strength of the clinical recommendations. The panel members considered the strength of each recommendation and evaluated the benefits and risks of applying the intervention. In formulating the recommendations, the panel considered patient and caregiver values, the cost of care, and feasibility. Results: Recommendations were developed for six management options for persistent OSA. Conclusions: The panel developed recommendations for the management of persistent pediatric OSA based on limited evidence and expert opinion. Important areas for future research were identified for each recommendation.

Adenoid hypertrophy-​diagnosis and treatment: the new S2k guideline

Hyperplasia of the pharyngeal tonsils is to be considered pathologic when nasopharyngeal symptoms of mechanical obstruction and/or chronic inflammation occur. Chronic Eustachian tube dysfunction can result in various middle ear diseases such as conductive hearing loss, cholesteatoma, and recurrent acute otitis media. During examination, attention should be paid to the presence of adenoid facies (long face syndrome), with a permanently open mouth and visible tip of the tongue. In the case of severe symptoms and/or failure of conservative treatment, adenoidectomy is usually performed on an outpatient basis. Conventional curettage remains the established standard treatment in Germany. Histologic evaluation is indicated for clinical evidence of mucopolysaccharidoses. Due to the risk of hemorrhage, the preoperative bleeding questionnaire, which is obligatory before every pediatric surgery, is referred to. Recurrence of adenoids is possible despite correct adenoidectomy. Before discharge home, otorhinolaryngologic inspection of the nasopharynx for secondary bleeding should be performed and anesthesiologic clearance obtained.

Beyond Polysomnography: Clinical Assessment of Pediatric Sleep Health and Sleep Problems

This chapter reviews the Peds B-SATED model of pediatric sleep health and common pediatric sleep problems. Aspects of pediatric sleep health and sleep problems are considered across development, from infants through adolescents. Finally, information about clinical screening in both primary and specialty care is discussed, and subjective sleep questionnaires are reviewed.

Effect of different head-high lateral extubation on adverse reactions in the peri-extubation period of pediatric OSAS surgery under general anesthesia

BACKGROUND

Children with OSAS are prone to various airway complications during tracheal extubation after tonsillectomy and adenoidectomy due to oropharyngeal secretions and oozing blood. However, few studies have examined the effect of position on airway complications after tracheal extubation in children with OSAS. The aim of this study was to investigate the appropriate position for extubation in children with OASA.

METHODS

A total of 459 children aged 3-14 years with OSAS who underwent tonsillectomy and adenoidectomy were recruited for this study. All children were treated with the same surgical approach and standard anesthesia methods of induction of anesthesia, tracheal intubation and maintenance of anesthesia. At the end of surgery, the children were delivered to the post anesthesia care unit and randomly divided into three groups: Group A: Head-high 0° in lateral position; Group B: Head-high 15° in lateral position; Group C: Head-high 30° in lateral position. The main outcomes of this study were the pulse oxygen saturation (SpO₂) and the Sedation-Agitation Scale (SAS) scores of the children after extubation, the outflow of oral-nasal secretions and the respiratory complications. Secondary outcomes were blood pressure, heart rate, end-respiratory carbon dioxide, respiratory rate, and post-operative awakening time of the children in three groups.

RESULTS

Data from a total of 423 children were statistically analyzed, 141 in Group A, 142 in Group B, and 140 in Group C. The main results showed a significant decrease in choking response after extubation in Group B (46.5%) and Group C (40.7%) compared to Group A (60.3%) (P < 0.05). The SAS score for postoperative agitation was higher in Group A (4.6 [Formula: see text] 0.9) than in Group B (4.4 [Formula: see text] 0.7) and Group C (4.3 [Formula: see text] 0.6) (P < 0.05). Also the SpO₂ after extubation was higher in Group B (97.2%) and Group C (97.1%) than in Group A (95.8%) (P < 0.05). In contrast, there was no difference in the occurrence of respiratory complication and postoperative agitation in children between Group B and Group C (all P > 0.05). In addition, there was no difference in the amount of oral-nasal secretions among the children in the three groups (all P > 0.05).

CONCLUSION

The head-high 15° lateral position and head-high 30° lateral position can reduce the incidence of airway complications and agitation and provide safe and comfortable extubation conditions for children during the peri-extubation period after tonsillectomy and adenoidectomy, which has certain clinical guidance value.

Temporal and Regional Trends in Obstructive Sleep Apnea Using Administrative Health Data in Alberta, Canada

Rationale: Obstructive sleep apnea (OSA) is a common treatable condition with important health and societal consequences. Objectives: We aimed to assess the annual incidence and prevalence of clinically recognized and geographic clustering of OSA in Alberta, Canada, using administrative health data case definitions. Methods: We used two administrative health databases in Alberta to identify ICD-9 and ICD-10 (International Classification of Diseases, Ninth and 10th Revisions, respectively) diagnostic codes for adults and children at least 2 years old diagnosed with OSA between 2003 and 2020. We defined OSA using an algorithm developed and validated in Alberta: at least three claims or one hospitalization within 2 years. We mapped residential postal codes to 70 subregional health authorities (SRHAs). Crude, age group- and sex-specific incidence and prevalence, and age group- and sex-standardized rates were calculated for Alberta and SRHAs. Spatial scan statistics identified clusters of SRHAs in which OSA cases were higher (hot spots) or lower (cold spots) than expected. Results: Between 2003 and 2020, OSA prevalence increased from 0.14% to 4.59%. The annual incidence of OSA increased after 2013. Incidence and prevalence were higher in older adults and children aged 2-11 years compared with 12-17 years. Cluster analysis revealed regional variation in OSA incidence and prevalence over time with no consistent pattern except for cold spots in one large metropolitan center (Calgary). Conclusions: From 2003 to 2020, the incidence and prevalence of clinically recognized OSA increased but varied by geography. Administrative health data can be used to guide interventions aimed at improving health service delivery and the quality of OSA care.

Effect of Sleep Changes on Health-Related Quality of Life in Healthy Children: A Secondary Analysis of the DREAM Crossover Trial

IMPORTANCE

Little is known regarding the effect of poor sleep on health-related quality of life (HRQOL) in healthy children.

OBJECTIVE

To determine the effect of induced mild sleep deprivation on HRQOL in children without major sleep issues.

DESIGN, SETTING, AND PARTICIPANTS

This prespecified secondary analysis focused on HRQOL, a secondary outcome of the Daily Rest, Eating, and Activity Monitoring (DREAM) randomized crossover trial of children who underwent alternating weeks of sleep restriction and sleep extension and a 1-week washout in between. The DREAM trial intervention was administered at participants' homes between October 2018 and March 2020. Participants were 100 children aged 8 to 12 years who lived in Dunedin, New Zealand; had no underlying medical conditions; and had parent- or guardian-reported normal sleep (8-11 hours/night). Data were analyzed between July 4 and September 1, 2022.

INTERVENTIONS

Bedtimes were manipulated to be 1 hour later (sleep restriction) and 1 hour earlier (sleep extension) than usual for 1 week each. Wake times were unchanged.

MAIN OUTCOMES AND MEASURES

All outcome measures were assessed during both intervention weeks. Sleep timing and duration were assessed using 7-night actigraphy. Children and parents rated the child's sleep disturbances (night) and impairment (day) using the 8-item Pediatric Sleep Disturbance and 8-item Sleep-Related Impairment scales of the Patient-Reported Outcomes Measurement Information System questionnaire. Child-reported HRQOL was assessed using the 27-item KIDSCREEN questionnaire with 5 subscale scores and a total score. Both questionnaires assessed the past 7 days at the end of each intervention week. Data were presented as mean differences and 95% CIs between the sleep restriction and extension weeks and were analyzed using intention to treat and an a priori difference in sleep of at least 30 minutes per night.

RESULTS

The final sample comprised 100 children (52 girls [52%]; mean [SD] age, 10.3 [1.4] years). During the sleep restriction week, children went to sleep 64 (95% CI, 58-70) minutes later, and sleep offset (wake time) was 18 (95% CI, 13-24) minutes later, meaning that children received 39 (95% CI, 32-46) minutes less of total sleep per night compared with the sleep extension week in which the total sleep time was 71 (95% CI, 64-78) minutes less in the per-protocol sample analysis. Both parents and children reported significantly less sleep disturbance at night but greater sleep impairment during the day with sleep restriction. Significant standardized reductions in physical well-being (standardized mean difference [SMD], -0.28; 95% CI, -0.49 to -0.08), coping in a school environment (SMD, -0.26; 95% CI, -0.42 to -0.09), and total HRQOL score (SMD, -0.21; 95% CI, -0.34 to -0.08) were reported by children during sleep restriction, with an additional reduction in social and peer support (SMD, -0.24; 95% CI, -0.47 to -0.01) in the per-protocol sample analysis.

CONCLUSIONS AND RELEVANCE

Results of this secondary analysis of the DREAM trial indicated that even 39 minutes less of sleep per night for 1 week significantly reduced several facets of HRQOL in children. This finding shows that ensuring children receive sufficient good-quality sleep is an important child health issue.

Expert Consensus Statement: Management of Pediatric Persistent Obstructive Sleep Apnea After Adenotonsillectomy

OBJECTIVE

To develop an expert consensus statement regarding persistent pediatric obstructive sleep apnea (OSA) focused on quality improvement and clarification of controversies. Persistent OSA was defined as OSA after adenotonsillectomy or OSA after tonsillectomy when adenoids are not enlarged.

METHODS

An expert panel of clinicians, nominated by stakeholder organizations, used the published consensus statement methodology from the American Academy of Otolaryngology-Head and Neck Surgery to develop statements for a target population of children aged 2-18 years. A medical librarian systematically searched the literature used as a basis for the clinical statements. A modified Delphi method was used to distill expert opinion and compose statements that met a standardized definition of consensus. Duplicate statements were combined prior to the final Delphi survey.

RESULTS

After 3 iterative Delphi surveys, 34 statements met the criteria for consensus, while 18 statements did not. The clinical statements were grouped into 7 categories: general, patient assessment, management of patients with obesity, medical management, drug-induced sleep endoscopy, surgical management, and postoperative care.

CONCLUSION

The panel reached a consensus for 34 statements related to the assessment, management and postoperative care of children with persistent OSA. These statements can be used to establish care algorithms, improve clinical care, and identify areas that would benefit from future research.

An observational pragmatic quality-of-life study on paediatric tonsillectomy and waiting for surgery

PURPOSE

To investigate parental perceptions of the effects of tonsillectomy on their child's quality of life while awaiting and following surgery in an Australian public health system.

METHODS

An observational pragmatic study was undertaken at a tertiary Australian hospital. Parents of paediatric patients (2-16 years of age) listed for tonsillectomy completed a validated quality-of-life questionnaire (T-14 Paediatric Throat Disorders Outcome Test) at the initial consultation, on day of surgery, 6 weeks post-operatively and 6 months post-operatively. T-14 scores were compared using the Related-Samples Wilcoxon Signed Rank Test.

RESULTS

Parents of 167 children participated in this study. There was a median wait time of 174 days (IQR 108-347) from the initial consultation until the day of surgery, with no significant change in median T-14 scores (35 [IQR 22-42] vs 36 [IQR 22-42]; n = 63; p > 0.05). There was a significant decrease from pre-operative T-14 scores to 6 weeks post-operatively (33.5 [IQR 22-42] vs 2 [IQR 0-5]; n = 160; p < 0.001), and this was sustained with a minor improvement at 6 months post-operatively (6 weeks 2 [IQR 0-5] vs 6 months 0 [IQR 0-2]; n = 148; p < 0.001).

CONCLUSIONS

Paediatric tonsillectomy improves quality of life with a sustained benefit in the long term. There is no improvement to the patient's quality of life while awaiting tonsillectomy, thus patient welfare can be improved through reducing waiting times for surgery.

Comparison of Caregiver- and Child-Reported Quality of Life in Children With Sleep-Disordered Breathing

OBJECTIVE

Caregivers frequently report poor quality of life (QOL) in children with sleep-disordered breathing (SDB). Our objective is to assess the correlation between caregiver- and child-reported QOL in children with mild SDB and identify factors associated with differences between caregiver and child report.

STUDY DESIGN

Analysis of baseline data from a multi-institutional randomized trial SETTING: Pediatric Adenotonsillectomy Trial for Snoring, where children with mild SDB (obstructive apnea-hypopnea index <3) were randomized to observation or adenotonsillectomy.

METHODS

The Pediatric Quality of Life Inventory (PedsQL) assessed baseline global QOL in participating children 5 to 12 years old and their caregivers. Caregiver and child scores were compared. Multivariable regression assessed whether clinical factors were associated with differences between caregiver and child report.

RESULTS

PedsQL scores were available for 309 families (mean child age, 7.0 years). The mean caregiver-reported PedsQL score was higher at 75.2 (indicating better QOL) than the mean child-reported score of 67.9 (P < .001). The agreement between caregiver and child total PedsQL scores was poor, with intraclass correlation coefficients of 0.03 (95% CI, -0.09 to 0.15) for children 5 to 7 years old and 0.21 (95% CI, 0.03-0.38) for children 8 to 12 years old. Higher child age and health literacy were associated with closer agreement between caregiver and child report.

CONCLUSION

Caregiver- and child-reported global QOL in children with SDB was weakly correlated, more so for young children. In pediatric SDB, child-perceived QOL may be poorer than that reported by caregivers. Further research is needed to assess whether similar trends exist for disease-specific QOL metrics.

Correlations between objective and subjective outcomes after adenotonsillar surgery in children with OSA

Objectives

To investigate whether the OSA-18 questionnaire and a postoperative patient-reported outcome measure (PROM) question correlated with polysomnography (PSG) data.

Methods

A prospective study of otherwise healthy young children with moderate to severe obstructive sleep apnea (OSA) to investigate if the obstructive apnea-hypopnea index (OAHI) before and 6-12 months after adenotonsil surgery correlated with the OSA-18 total symptom score (TSS) and the sleep disturbance subscale (SDS), as well as a PROM question on symptom improvement with responses on a 4-grade Likert scale.

Results

Of 201 children, 173 (86%) had complete data of OAHI and OSA-18 pre- and postoperatively. The mean age was 3.2 years (SD 1.0) and the mean OAHI was 15.9 (11.3). Significant correlations between changes in the OAHI and OSA-18 were found, both TSS (r = 0.29, p < .001) and SDS (r = 0.53, p < .001). A total of 136 (68%) patients responded to the PROM question, the majority of whose symptoms had disappeared (n = 102) or almost disappeared (n = 30). Four patients had unchanged symptoms, and none had worsening symptoms. A correlation was found between the PROM question and a change in the OAHI (r = 0.36, p < .001), as well as a change in the OSA-18 TSS (r = 0.24, p = .006) and the SDS (r = 0.34, p < .001). The specificity of the PROM question for prediction of a postoperative OAHI < 2 was 82%, and the sensitivity was 38%.

Conclusion

Changes in the OAHI significantly correlated with changes in the OSA-18, especially with the sleep disturbance scale, which could be an alternative for evaluation at follow-ups.

The effect of iron deficiency on quality of life outcomes after surgery for obstructive sleep apnoea

AIM

This study aimed to assess the effect of iron deficiency on parent-reported changes in quality of life (QOL) among children receiving an adenotonsillectomy for paediatric obstructive sleep apnoea (OSA).

METHODS

This was a retrospective review study that recruited children under 16 years of age undergoing an adenotonsillectomy, adenoidectomy, or tonsillectomy for clinically diagnosed paediatric OSA between June 2020 and January 2021 inclusive, in Western Australia. The main outcome measures for this study were changes in QOL by age group and iron status, defined by an absolute change of more than 3 points on OSA-18 survey domains.

RESULTS

About 249 participants had iron studies performed on perioperative blood samples drawn at operation and completed both pre-operative and post-operative OSA-18 QOL questionnaires at initial consultation and 8-12 weeks post-surgery, respectively. 41.8% were iron deficient, 53.8% were borderline iron deficient and 4.4% had normal iron levels. Following surgery, a decrease was observed for all OSA-18 score domains in post-operation scores compared to pre-operation scores in both iron-deficient and borderline iron-deficient cohorts. 'Daytime Problems' in the <2 years group, within the iron-deficient cohort, was the only domain that found to be non-superior (i.e. 'not better') following surgery.

CONCLUSIONS

Following adenotonsillectomy, patients with paediatric OSA reported significant improvements in QOL regardless of their iron status. Those undergoing an adenotonsillectomy for paediatric OSA had a high prevalence of iron deficiency at operation, especially those under 6 years of age.

Effects of Treatment of Sleep Disordered Breathing on Sleep Macro- and Micro-Architecture in Children with Down Syndrome

Background: Children with Down syndrome (DS) are at increased risk of obstructive sleep disordered breathing (SDB), which is associated with intermittent hypoxia and sleep disruption affecting daytime functioning. We aimed to examine the effects of treatment of SDB on sleep quality and daytime functioning in children with DS. Methods: Children with DS and SDB (n = 24) completed a baseline and follow-up overnight polysomnographic (PSG) study 22 ± 7 months (mean ± SD) later. Sleep micro-architecture was assessed using EEG spectral analysis, and parents completed a number of questionnaires assessing sleep, behavior, daytime functioning, and quality of life (QOL). Results: A total of nine children (38%) were treated. At baseline, the treated group had more severe SDB compared to the untreated group. SDB severity was significantly improved from 40.3 ± 46.9 events/h to 17.9 ± 26.9 events/h (p < 0.01) at follow up in children who were treated. There were no significant differences in sleep macro-architecture parameters from baseline to follow up in either the treated or untreated group. Sleep micro-architecture was not different between studies in the treated group, however this tended to improve in the untreated group, particularly in REM sleep. Daytime functioning and behavior were not different between the studies in either group, however, QOL improved after treatment. Conclusions: Our study identified that treatment of SDB improves severity of the disease as defined by PSG, and this was associated with parental reports of improved QOL, despite treatment having no demonstrable impacts on sleep quality, behavior, or daytime functioning.

Secondary Analyses of the Childhood Adenotonsillectomy Trial: A Narrative Review

Importance

Adenotonsillectomy, performed for approximately 500 000 children annually in the US alone, is the first line of treatment of pediatric obstructive sleep apnea (OSA). The Childhood Adenotonsillectomy Trial (CHAT), the first randomized clinical trial to test the efficacy of adenotonsillectomy, compared the management of pediatric nonsevere OSA by early adenotonsillectomy (eAT) vs watchful waiting with supportive care. Since the publication of the primary article in 2013, the CHAT study data set were made available via the National Sleep Research Resource, which allowed researchers to address a range of additional clinical questions relevant to the care of children with OSA. This review focuses on secondary analyses associated with the CHAT data set as grouped by the outcome of interest.

Observations

The results of most secondary analyses suggest that children who underwent eAT experienced the greatest improvements in symptom burden, sleepiness, parent-reported behavior, and quality of life. Changes in other domains, such as cognition, cardiovascular physiology, and metabolic indicators, were modest and selective. The associations between most treatment outcomes and polysomnographic parameters were weak. Symptoms were poor predictors of OSA severity. The results from these secondary analyses benefitted from the rigor of multicenter design and centralized polysomnography interpretation in CHAT. However, the exclusion of younger preschool-aged children and children with primary snoring limited the generalizability of findings. In addition, because caregivers were not masked, some of the parent-reported outcomes may have been inflated.

Conclusions and Relevance

The results of this narrative review suggest that CHAT provides a model for future OSA-related studies in children for design, conduct, and subsequent reuse of the study data set, and its findings have advanced our understanding of the pathophysiology and management of pediatric nonsevere OSA. Directions for future research include whether the findings from this landmark study are generalizable to younger children and children with primary snoring and severe OSA. Similar studies may help address practice variability associated with pediatric OSA and help identify children who are most likely to benefit from undergoing eAT.

Post-Operative Patients’ Satisfaction and Quality of Life Assessment in Adult Patients with Obstructive Sleep Apnea Syndrome (OSAS)

Background: The treatment for severe OSAS includes maxillomandibular advancement surgical option in selected cases. The aim of this study was to evaluate the post-operative impact of bimaxillary surgery on satisfaction and consequently the quality of life of these patients. Methods: This study included 18 patients with severe OSAS who received maxillomandibular advancement surgery. Patients were divided into Group A (operated by CAD/CAM) and Group B (conventional surgery). The impact of bimaxillary surgery on satisfaction and quality of life of these patients was evaluated by utilizing post-operative life quality and Rustemeyer’s patient-satisfaction-based survey. Results: A total of 18 adult OSAS patients (Group A: 11 patients, Group B: 7 patients) with a mean age of 44.39 years (SD ± 9.43) were included. Mean follow-up period was 32.64 months (SD ± 21.91). No intra-operative complications were seen in any patients. Post-operative complication was seen in one patient and the mandible did not integrate. According to the results, overall post-operative satisfaction score was 79.72% (SD ± 9.96). There was no significant difference among those in Group A and Group B. Conclusion: Maxillomandibular advancement surgery seems to be beneficial in terms of patients’ satisfaction in severe adult OSAS patients and can be considered as a valuable option in selected cases.

OSAHS Growth Impairment and Resolution after Adenotonsillectomy in Children

INTRODUCTION

One of the most important complications of OSAHS in children is growth delay. The aim of this study was to investigate changes in clinical body growth, and laboratory growth in children with OSAHS after adeno-tonsillar surgery.

MATERIALS AND METHODS

In our study, among 102 children suffering from sleep-disordered breathing, 70 met the inclusion criteria because they were affected by OSAHS and adenotonsillar hypertrophy. In total, 96 children affected by adeno-tonsillar hypertrophy (55 males and 41 females) underwent nocturnal cardiorespiratory monitoring with Embletta MPR, monitoring for post-operative 24 hours. Patients underwent blood sampling to evaluate preoperative GH and IGF-1 serum levels, "placement" in Cacciari's growth charts and adenotonsillectomy and saturation monitoring for post-operative 24 hours. According to auxological parameters, 82.86% of the patients were below the fiftieth percentile of BMI Cacciari's growth charts and IGF-1 preoperative serum levels were below the normal range. All patients underwent adenotonsillectomy.

RESULTS

All 70 patients recovered from OSAHS according to the results of nocturnal cardiorespiratory monitoring after six months. IGF-1 serum levels significantly increased after three months and one year after. All the auxological parameters showed a significant increase after surgery. We calculated the average annual growth in height of the patients before and after adenotonsillectomy (AT): the growth rate was impaired by OSAHS (5.4±1.3 cm/year), while in the following year post-surgery we found a significant growth speed acceleration (9.9±1.7 cm/year, P=0.001).

CONCLUSIONS

In conclusion, growth delay in children can be caused by OSAHS, and when it is due to adenotonsillar hypertrophy, adenotonsillectomy is to be considered as the therapy of choice.

Treatment Considerations for Obstructive Sleep Apnea in Pediatric Down Syndrome

Children with Down syndrome (DS) are at high risk for developing obstructive sleep apnea (OSA) compared to children without DS. The negative impact of OSA on health, behavior, and cognitive development in children with DS highlights the importance of timely and effective treatment. Due to the higher prevalence of craniofacial and airway abnormalities, obesity, and hypotonia in patients with DS, residual OSA can still occur after exhausting first-line options. While treatment commonly includes adenotonsillectomy (AT) and continuous positive airway pressure (CPAP) therapy, additional therapy such as medical management and/or adjuvant surgical procedures need to be considered in refractory OSA. Given the significant comorbidities secondary to untreated OSA in children with DS, such as cardiovascular and neurobehavioral consequences, more robust randomized trials in this patient population are needed to produce treatment guidelines separate from those for the general pediatric population of otherwise healthy children with OSA. Further studies are also needed to look at desensitization and optimization of CPAP use in patients with DS and OSA.

Characteristics of Children Likely to Have Spontaneous Resolution of Obstructive Sleep Apnea: Results from the Childhood Adenotonsillectomy Trial (CHAT)

OBJECTIVE

To evaluate if cardiopulmonary coupling (CPC) calculated sleep quality (SQI) may have a role in identifying children that may benefit from other intervention than early adenotonsillectomy (eAT) in management of obstructive sleep apnea (OSA).

METHODS

A secondary analysis of electrocardiogram-signals (ECG) and oxygen saturation-data (SpO₂) collected during polysomnography-studies in the prospective multicenter Childhood Adenotonsillectomy Trial (CHAT) to calculate CPC-SQI and apnea hypopnea index (AHI) was executed. In the CHAT, children 5-9 years with OSA without prolonged oxyhemoglobin desaturations were randomly assigned to adenotonsillectomy (eAT) or watchful waiting with supportive care (WWSC). The primary outcomes were to document change in attention and executive function evaluated with the Developmental Neuropsychological Assessment (NEPSY). In our analysis, children in the WWSC-group with spontaneous resolution of OSA (AHI_Obstructive < 1.0) and high-sleep quality (SQI ≥ 75) after 7-months were compared with children that showed residual OSA.

RESULTS

Of the 227 children randomized to WWSC, 203 children had available data at both baseline and 7-month follow-up. The group that showed resolution of OSA at month 7 (n = 43, 21%) were significantly more likely to have high baseline SQI 79.96 [CI_95% 75.05, 84.86] vs. 72.44 [CI_95% 69.50, 75.39], p = 0.005, mild OSA AHI_Obstructive 4.01 [CI_95% 2.34, 5.68] vs. 6.52 [CI_95% 5.47, 7.57], p= 0.005, higher NEPSY-attention-executive function score 106.22 [CI_95% 101.67, 110.77] vs. 101.14 [CI_95% 98.58, 103.72], p = 0.038 and better quality of life according to parents 83.74 [CI_95% 78.95, 88.54] vs. 77.51 [74.49, 80.53], p = 0.015. The groups did not differ when clinically evaluated by Mallampati score, Friedman palate position or sleep related questionnaires.

CONCLUSIONS

Children that showed resolution of OSA were more likely to have high-SQI and mild OSA, be healthy-weight and have better attention and executive function and quality of life at baseline. As this simple method to evaluate sleep quality and OSA is based on analyzing signals that are simple to collect, the method is practical for sleep-testing, over multiple nights and on multiple occasions. This method may assist physicians and parents to determine the most appropriate therapy for their child as some children may benefit from WWSC rather than interventions. If the parameters can be used to plan care a priori, this would provide a fundamental shift in how childhood OSA is diagnosed and managed.

Impact of sleep-disordered breathing on behavior and quality of life in children aged 2 to 7 years with non-syndromic cleft lip and/or palate

INTRODUCTION

Children with cleft are at high risk for sleep-disordered breathing (SDB). However, little is known about the impact of SDB in this pediatric population. The aim of this study was to investigate whether SDB play a role in behavior and quality of life (QoL) in young children with cleft.

METHODS

Cross-sectional study of 95 children aged 2.0-7.9 years with cleft palate. Parents completed a sleep (Pediatric Sleep questionnaire), a behavior (Conners' Early Childhood scale), and a generic health-related QoL (KINDL questionnaire) assessment. Symptomatic children were referred for a polysomnography (PSG).

RESULTS

Overall, 14.7% of children (49.5% boys) screened positive for SDB and 27.4% had a PSG, which identified 84.6% with sleep apnea (apnea-hypopnea index [AHI] ≥1) and 27.2% with AHI ≥5. Positive screening for SDB was associated with elevated T-scores for anxiety and physical symptoms, significant differences in mean T-scores for inattention/hyperactivity (64.2 ± 15.7 vs. 53.9 ± 11.4, p = .02), social functioning/atypical behaviour, social functioning (60.6 ± 11.7 vs. 51.9 ± 7.3, p = .004 and 59.5 ± 10.9 vs. 51.2 ± 8.0, p = .01) and mood (57.5 ± 8.2 vs. 50.7 ± 8.2, p = .03). Lower QoL scores for emotional and family well-being were also reported in children with SDB (80.7 ± 13.4 vs. 90.0 ± 8.7, p = .01, 66.7 ± 15.8 vs. 76.9 ± 11.9, p = .04). Children with AHI ≥5 compared to those with AHI ≥1 and <5 showed significant differences in mean T-score for aggressive behaviour (65.2 ± 12.1 vs. 52.3 ± 11.3, p = .04), defiant temper (62.8 ± 9.2 vs. 51.6 ± 10.2, p = .03) and lower family QoL scores (59.4 ± 15.2 vs. 77.1 ± 9.6, p = .006).

CONCLUSIONS

In children with cleft palate the presence of SDB symptoms and moderate/severe sleep apnea was associated with behavioral (internalizing/externalizing) problems and lower family well-being.

Evidence of sleep duration and weekend sleep recovery impact on suicidal ideation in adolescents with allergic rhinitis

STUDY OBJECTIVES

Sleep problems are common in allergic rhinitis (AR) and are a modifiable risk factor for suicidal ideation. However, the effect of sleep duration and weekend catch-up sleep (WCUS)-sleep time on weekends that exceeds sleep time on weekdays-on suicidal ideation for adolescents with AR is unknown. The objective of this study was to explore whether sleep duration and WCUS have an impact on suicidal ideation among adolescents with AR.

METHODS

From the annual Korean Youth Risk Behavior Web-Based Surveys (completed from 2013-2017), data were obtained from a stratified, multistage, clustered sample. Using self-reported questionnaires, students provided doctor-diagnosed AR and sleep time.

RESULTS

Among 134,417 and 262,653 adolescents with and without AR, respectively, those with AR compared with those without AR had more sleep dissatisfaction (46.6% vs 40.8%), slept less (sleep duration: 6.71 ± 1.37 hours vs 7.01 ± 1.48 hours), and had longer WCUS (3.46 ± 0.11 hours vs 2.11 ± 0.14 hours). After adjustment, the odds ratio of patients with sleep dissatisfaction was a 1.22 (95% confidence interval, 1.17-1.28) times higher risk of suicidal ideation than in those with sleep satisfaction. For average sleep duration (defining 7-8 hours as the reference), the odds ratio of short sleep (≤ 5 hours) was 1.45 (95% confidence interval, 1.32-1.53). Notably, long WCUS (≥ 2 hours) was significantly associated with decreased suicidal ideation (odds ratio, 0.85; 95% confidence interval, 0.81-0.92).

CONCLUSIONS

Although further research is needed to clarify this association, under the condition of sleep deprivation, WCUS at a certain extent may be associated with a low risk for suicidal ideation in adolescents with AR.

Racial and Ethnic Disparities in Utilization of Tonsillectomy among Medicaid-Insured Children

OBJECTIVE

To examine racial differences in tonsillectomy with or without adenoidectomy (T&A) for sleep-disordered breathing (SDB) among Medicaid-insured children.

STUDY DESIGN

Retrospective analysis of the 2016 MarketScan Multistate Medicaid Database was performed for children ages 2 to <18 years with a diagnosis of SDB. Patients with medical complexity and infectious indications for surgery were excluded. Racial groups were categorized into non-Hispanic White, non-Hispanic Black, Hispanic, and other. Adjusted multivariate logistic regression was used to determine if race/ethnicity was a significant predictor of obtaining T&A, polysomnography, and time to intervention.

RESULTS

There were 83 613 patients with a diagnosis of SDB that met inclusion criteria, of which 49.2% were female with a mean age of 7.9 ± 3.8 years. The cohort consisted of White (49.2%), Black (30.0%), Hispanic (8.0%), and other (13.2%) groups. Overall, 15.4% underwent T&A. Black (82.2%) and Hispanic (82.3%) children had significantly higher rates of no intervention and White patients had the lowest rate of no intervention (76.9%; P < .0001) and the highest rate of T&A (18.7%; P < .0001). Mean time to surgery was shortest in White compared with Black children (P < .0001). Logistic regression adjusting for age and sex showed that Black children had 45% reduced odds of surgery (95% CI 0.53-0.58), Hispanic 38% (95% CI 0.58-0.68), and other 35% (95% CI 0.61-0.70) compared with White children with Medicaid insurance.

CONCLUSIONS

Racial and ethnic disparities exist in the utilization of T&A for children with SDB enrolled in Medicaid. Future studies that investigate possible sources for these differences and more equitable care are warranted.

Adenotonsillectomy as a treatment for sleep-disordered breathing in children with ADHD

Sleep-disordered breathing (SDB) and attention deficit hyperactivity disorder (ADHD) are common disorders diagnosed in children. Although these diagnoses were previously considered unrelated, research now is showing that some symptoms of ADHD, specifically oppositional behavior, hyperactivity, and impulsivity, can be related to SDB in children and differs from bona fide ADHD. This article explores the connection between the two disorders and the importance of identifying and screening for SDB in children presenting with similar symptoms related to ADHD. The article also examines symptom improvement in patients with ADHD symptoms after an adenotonsillectomy, one of the first-line treatments for children diagnosed with SDB; this procedure may reduce the need for long-term stimulant use in some children with ADHD.

The effect of rapid maxillary expansion on the upper airway's aerodynamic characteristics

Background

The effect of rapid maxillary expansion (RME) on the upper airway (UA) has been studied earlier but without a consistent conclusion. This study aims to evaluate the outcome of RME on the UA function in terms of aerodynamic characteristics by applying a computational fluid dynamics (CFD) simulation.

Methods

This retrospective cohort study consists of seventeen cases with two consecutive CBCT scans obtained before (T0) and after (T1) RME. Patients were divided into two groups with respect to patency of the nasopharyngeal airway as expressed in the adenoidal nasopharyngeal ratio (AN): group 1 was comprised of patients with an AN ratio < 0.6 and group 2 encompassing those with an AN ratio ≥ 0.6. CFD simulation at inspiration and expiration were performed based on the three-dimensional (3D) models of the UA segmented from the CBCT images. The aerodynamic characteristics in terms of pressure drop (ΔP), maximum midsagittal velocity (V_ms), and maximum wall shear stress (P_ws) were compared by paired t-test and Wilcoxon test according to the normality test at T0 and T1.

Results

The aerodynamic characteristics in UA revealed no statistically significant difference after RME. The maximum V_ms (m/s) decreased from 2.79 to 2.28 at expiration after RME (P = 0.057).

Conclusion

The aerodynamic characteristics were not significantly changed after RME. Further CFD studies with more cases are warranted.

Effectiveness of Adenotonsillectomy vs Watchful Waiting in Young Children With Mild to Moderate Obstructive Sleep Apnea: A Randomized Clinical Trial

Importance

Adenotonsillectomy (ATE) is one of the most common surgical procedures to treat children with obstructive sleep apnea (OSA), but to our knowledge there are no randomized clinical trials confirming the benefit of surgery compared with watchful waiting in children between 2 and 4 years of age.

Objective

To determine whether ATE is more effective than watchful waiting for treating otherwise healthy children with mild to moderate OSA.

Design, Setting, and Participants

This randomized clinical trial was conducted from December 2014 to December 2017 at the Otorhinolaryngology Department of the Karolinska University Hospital, Stockholm, Sweden. A total of 60 children, 2 to 4 years of age, with an obstructive apnea-hypopnea index (OAHI) score of 2 or greater and less than 10, were randomized to ATE (n = 29) or watchful waiting (n = 31). A total of 53 participants (88%; ATE, n = 25; watchful waiting, n = 28) completed the study. Data were analyzed from August 2018 to December 2018.

Interventions

Adenotonsillectomy.

Main Outcomes and Measures

The primary outcome was the difference between the groups in mean OAHI score change. Secondary outcomes were other polysomnography parameters, score on the Obstructive Sleep Apnea-18 (OSA-18) questionnaire, and subgroup analyses. Polysomnography and the OSA-18 questionnaire were completed at baseline and after 6 months.

Results

Of the 60 included children, 34 (57%) were boys and the mean (SD) age at first polysomnography was 38 (9) months. Both groups had a decrease in mean OAHI score, and the difference in mean OAHI score change between the groups was small (-1.0; 95% CI, -2.4 to 0.5), in favor of ATE. However, there were large differences between the groups in favor of ATE regarding the OSA-18 questionnaire (eg, total OSA-18 score: -17; 95% CI, -24 to -10). Also, a subgroup analysis of 24 children with moderate OSA (OAHI ≥5 and <10) showed a meaningful difference in mean OAHI score change between the groups in favor of ATE (-3.1; 95% CI, -5.7 to -0.5). Of 28 children, 10 (36%) in the watchful waiting group received ATE after the follow-up, and 7 of these had moderate OSA at baseline.

Conclusions and Relevance

This randomized clinical trial found only small differences between the groups regarding changes in OAHI, but further studies are needed. However, there were large improvements in quality of life after ATE. These results suggest that otherwise healthy children with mild OSA and mild effect on quality of life may benefit from watchful waiting, while children with moderate OSA should be considered for ATE.

The impact of childhood obstructive sleep apnea on speech and oral language development: a systematic review

PURPOSE

The purpose of this systematic review was to review and synthesize the current evidence on speech and language outcomes of children with Obstructive Sleep Apnea (OSA), or more broadly sleep-disordered breathing.

METHOD

A comprehensive literature search was conducted across 5 databases. Studies were selected based on the following criteria: 1) peer-reviewed research published between 2000 and 2020, 2) available in English or accessible non-English data, 3) children aged 2-13 years diagnosed with Sleep Disordered Breathing (SDB) or OSA, and 4) speech and language outcomes examined within research.

RESULTS

Studies were appraised using PEDro-P and the overall certainty of evidence using Grading of Recommendations Assessment, Development and Evaluation (GRADE). Six studies met the current review selection criteria: one paper examined speech outcomes and the remaining five examined receptive and expressive language outcomes. The overall quality of the body of evidence was rated as very low, with methodological weaknesses present in study designs and sample sizes.

CONCLUSION

Speech and language difficulties are common in children with OSA/SDB, in addition to neurocognitive and/or neurobehavioral issues. Further investigation of specific speech and language skills, which are compromised in this population, is needed to guide clinical practice and decision making, with particular involvement from speech-language pathologists.

Behavioural disorders and parental stress in children suffering from obstructive sleep apnoea syndrome: a pre- and post-adenotonsillectomy confrontation

The primary goal of the present study was to compare breathing difficulties resulting from OSAS to possible cognitive-behavioural problems of the child linked to their parents’ emotional-relational aspects. There is strong evidence that sleep breathing disorders are associated with behavioural alterations, a tendency towards aggressiveness, weak school performance and a clear disorder in continuous and selective attention other than vigilance status. Not all patients suffering from OSA have cognitive and/or behavioural manifestations; furthermore, the degree of dysfunction that the patient may present does not seem to be associated with the seriousness of sleep breathing disorder (SBD). It is therefore likely that genetic susceptibility associated with particular environmental factors has a role in determining phenotypic manifestations which are unique for every single patient. Questionnaires were given to parents, one regarding executive functions and one regarding parental stress: Conners’ Rating Scale Revised; Parenting Stress Index. All parents of children who suffer from moderate to severe OSA, with a McGill score of 3 to 4 and with no exclusion criteria are included in the study; behavioural and parental stress evaluation was made during hospitalisation and at 6 months after adenotonsillectomy. The results show that resolving OSAS led to important improvements in the competence and behavioural attitudes of the patient, as well as in relational and management difficulties by parents. The identification of such indicators could represent a support to surgical programming, even in non-severe SBD. Future research will have the goal of identifying standardised risk indicators that can provide further indications for surgical treatment in children up to 5 years of age.

Quality of life in children and adolescents with overweight or obesity: Impact of obstructive sleep apnea

OBJECTIVES

To investigate the association between obstructive sleep apnea (OSA) and health related quality of life (HRQOL) in children and adolescents referred to an obesity treatment clinic. In addition, we examined the association between body mass index standard deviation score (BMI SDS) and HRQOL comparing children and adolescents with overweight or obesity without OSA with a control group of children and adolescents with normal weight without OSA.

METHODS

This cross-sectional study included 130 children and adolescents with overweight or obesity (BMI SDS > 1.28) aged 7-18 years recruited from an obesity treatment clinic. The control group consisted of 28 children and adolescents with normal weight (BMI SDS ≤ 1.28) aged 7-18 years recruited from schools. Sleep examinations were performed using a type 3 portable sleep monitor, Nox T3. OSA was defined as apnea-hypopnea index (AHI) ≥ 2. HRQOL was measured by the Pediatric Quality of Life Inventory (PedsQL) 4.0 generic core scale.

RESULTS

A total of 56 children and adolescents with overweight or obesity were diagnosed with OSA (43%). The children and adolescents with OSA were older (p = 0.01) and had higher BMI SDS (p = 0.04) than children and adolescents without OSA. In generalized linear regression analyses adjusted for age, sex, BMI SDS and pubertal development stage there was no association between OSA or AHI and HRQOL in children and adolescents with overweight or obesity. In the analysis, including children and adolescents without OSA and the normal-weight control group, the generalized linear regression adjusted for age, sex and AHI revealed an association between BMI SDS and HRQOL (p < 0.001).

CONCLUSION

We found no association between AHI or OSA and HRQOL in children and adolescents with overweight or obesity. However, we found an association between BMI SDS and HRQOL in children and adolescents without OSA.

Sleep surgery in syndromic and neurologically impaired children

PURPOSE

To examine surgery performed for obstructive sleep apnea (OSA) in children with syndromic or neurologic comorbidities.

MATERIAL AND METHODS

Medical records of 375 children with OSA were retrospectively reviewed, including 142 patients with trisomy 21, 105 with cerebral palsy, 53 with muscular dystrophy, 32 with spinal muscular atrophy, 18 with mucopolysaccharidoses, 14 with achondroplasia, and 11 with Prader-Willi.

OUTCOME MEASURES

Apnea-hypopnea index (AHI), complications, length of postoperative stay, and endoscopic findings.

RESULTS

228 patients received 297 surgical interventions, with the remainder undergoing observation or positive pressure ventilation. Adenoidectomy was the most common procedure performed (92.1% of patients), followed by tonsillectomy (91.6%). Average AHI decreased following tonsillectomy, from 12.4 to 5.7 (p = 0.002). The most common DISE finding was the tongue base causing epiglottic retroflexion. Lingual tonsillectomy also resulted in an insignificant decrease in the AHI.

CONCLUSIONS

Adenotonsillectomy, when there is hypertrophy, remains the mainstay of management of syndromic and neurologically-impaired children with OSA. However, additional interventions are often required, due to incomplete resolution of the OSA. DISE is valuable in identifying remaining sites of obstruction and guiding future management.

Correlations between disease-specific quality of life and polysomnographic findings in children with obstructive sleep apnea

OBJECTIVES

Obstructive sleep apnea (OSA) can have a negative impact on quality of life in children. The OSA-18 is a disease-specific quality of life questionnaire for children. The questionnaire has been found to be a poor predictor of OSA diagnosed with polysomnography (PSG), yet OSA-18 scores do markedly improve after adenotonsillectomy. The aim of this study was to examine the correlations between OSA-18 and PSG findings, beyond the apnea hypopnea index (AHI).

METHODS

This study was a prospective study of children 2-6 years of age who were referred to an Ear, Nose and Throat department for adenoidectomy and/or tonsillectomy. Prior to surgery, all of the children underwent PSG and a physical examination, and their parent completed the OSA-18 questionnaire. Spearman correlations were used to determine the associations between OSA-18 scores and PSG parameters.

RESULTS

The sample consisted of 97 children who underwent PSG and their parents who answered the OSA-18 questionnaire. We found positive correlations between the AHI and both the OSA-18 total score (rho = 0.21, p = 0.04) and the sleep disturbance subscale (rho = 0.51, p < 0.01). The only other PSG parameter that significantly correlated with the OSA-18 was the number of awakenings and arousals per hour of sleep (rho = 0.29, p < 0.01).

CONCLUSION

We only found weak correlations between the OSA-18 score and PSG findings, suggesting the two methods are measuring different aspects of pediatric OSA.

Evaluation of symptoms of preopoperative and postoperative psychosomatic screening in children with adenoidectomy and adenotonsillectomy

INTRODUCTION

Adenoidectomy and adenotonsillectomy are very common operations in childhood. It is important to clarify their effects on this age group; in this study, we aimed to investigate the effects of the causative agent on children's mental health by using scales that help to screen for indications of mental disorders in children, who have had adenoidectomy or adenotonsillectomy, both before and after surgery. In this way, we aimed to investigate the effects of this factor on children's mental health.

MATERIALS AND METHODS

The study included 82 children aged 6-12 years with signs of upper respiratory tract obstruction or recurrent adenotonsilitis. Adenotonsillectomy was performed in 41 patients included in the study and adenoidectomy was performed in 41 patients included in the study. 40 healthy children matched with the patient groups in terms of age and gender were included in the control group. Patients, were divided into three groups, those who underwent adenoidectomy, patients undergoing adenotonsillectomy and those in the control group Preoperative and postoperative questionnaires were used to investigate the effect of tonsillectomy or adenoidectomy on the mental health of children. The Parents' Form for the Strengths and Difficulties Questionnaire, the Parental Form for the Children's Anxiety Screening Scale, the Sleeping Scale for Children and the Quality of Life Scale for Children were used in the screening.

RESULTS

In children, who underwent adenoidectomy/adenotonsillectomy due to recurrent infection and adeno/adenotonsillar hypertrophy; it was seen that there was a significant decrease in the scores for the Strengths and Difficulties Questionnaire, the Anxiety Screening Scale in Children, and the Sleep Scale in Children, and a significant increase in Quality of Life Scale for Children scores.

OUTCOME

In conclusion, adenoidectomy/adenotonsillectomy in children with sleep apnea due to recurrent episodes of infection and adeno/adenotonsillar hypertrophy was thought to prevent further neurobehavioral problems, likely to become more complex in the future, and to improve quality of life.

Sleep-disordered breathing in cystic fibrosis

INTRODUCTION

Cystic fibrosis (CF) is a life-shortening, genetic disease that affects approximately 30,000 Americans. Although patients frequently report snoring, mouth breathing, and insomnia, the extent to which sleep-disordered breathing (SDB) may underlie these complaints remains unknown.

METHODS

Single-center retrospective review of polysomnography results from referred patients with and without CF individually-matched (1:2) for age, gender, race, and body mass index (BMI).

RESULTS

Mean ages were 8.0 ± 5.2 (sd) and 35.9 ± 12.9 years, among 29 children and 23 adults with CF respectively. The CF and non-CF groups were well-matched in age and BMI. Subjects with vs. without CF had three times greater odds of moderate-severe SDB (apnea-hypopnea index (AHI) ≥ 5 in children, ≥ 15 in adults) (p = 0.01). Nocturnal oxygen saturation nadir (Minimum SpO₂) was lower among CF vs. non-CF groups (p = 0.002). For every 1-unit increase in AHI, the decline in Minimum SpO₂ was larger for subjects with vs. without CF (p = 0.05). In subjects with CF, forced expiratory volume in 1 s percent predicted (FEV1 PPD) was associated with Minimum SpO₂ (Pearson r = 0.68, p < 0.0001) but not AHI (r = -0.19, p = 0.27). For every 1-unit increase in AHI, magnitude of decline in Minimum SpO₂ was larger for those with low vs. normal FEV1 PPD (p = 0.01).

CONCLUSION

Severity of SDB may be worse among referred patients with vs. without CF. The SDB may modify the relationship between CF lung disease and nocturnal hypoxemia. Markers of lung disease severity including lung function do not predict SDB severity, suggesting the need for routine polysomnography to screen for this sleep disorder.

Weight change before and after adenotonsillectomy in children: An analysis based upon pre-surgery body mass category

OBJECTIVES

To determine the standardised body mass index (BMIz) trajectory before and after adenotonsillectomy/tonsillectomy between children in different weight classifications in a larger sample than has been studied previously, and to identify which patient factors would explain the difference in these outcomes.

DESIGN

We used a retrospective chart review and leveraged data of weight status pre- and post-adenotonsillectomy/tonsillectomy from a cohort of paediatric patients seen between May 2004 and April 2017.

SETTING

Data were collected from an electronic medical record at a single Midwest paediatric health system.

PARTICIPANTS

The study population included a convenience sample of 1,751 paediatric patients who underwent adenotonsillectomy or tonsillectomy and had at least two height and weight measurements recorded on the same date both before and after surgery.

MAIN OUTCOME MEASURES

Change in BMIz trajectories before and after surgery.

RESULTS

Of 1751 paediatric patients (ages 3-11) underwent adenotonsillectomy/tonsillectomy procedures. Age at time of surgery and gender were not significant predictors. Children in different weight classifications demonstrated differences in BMIz trajectory after surgery. Children with overweight/obesity experience a decrease in BMIz, whereas children with underweight or normal weight experience an increase in BMIz.

CONCLUSIONS

Improvement in weight status is seen after surgery: increased BMI for those underweight and decreased BMI for those with overweight/obesity. We advocate for behavioural strategies as a first-line treatment in children with underweight or overweight/obesity, and results suggest that coordinating these efforts alongside adenotonsillectomy/tonsillectomy when indicated for medical reasons may be warranted. However, further research is needed to confirm these findings due to the observational nature of this study.

Long-term Impact of Adenotonsillectomy on the Quality of Life of Children with Sleep-disordered breathing

Introduction  Adenotonsillectomy is the first-line treatment for obstructive sleep apnea secondary to adenotonsillar hypertrophy in children. The physical benefits of this surgery are well known as well as its impact on the quality of life (QoL), mainly according to short-term evaluations. However, the long-term effects of this surgery are still unclear.

Objective  To evaluate the long-term impact of adenotonsillectomy on the QoL of children with sleep-disordered breathing (SDB).

Method  This was a prospective non-controlled study. Children between 3 and 13 years of age with symptoms of SDB for whom adenotonsillectomy had been indicated were included. Children with comorbities were excluded. Quality of life was evaluated using the obstructive sleep apnea questionnaire (OSA-18), which was completed prior to, 10 days, 6 months, 12 months and, at least, 18 months after the procedure. For statistical analysis, p -values lower than 0.05 were defined as statistically significant.

Results  A total of 31 patients were enrolled in the study. The average age was 5.2 years, and 16 patients were male. The OSA-18 scores improved after the procedure in all domains, and this result was maintained until the last evaluation, done 22 ± 3 months after the procedure. Improvement in each domain was not superior to achieved in other domains. No correlation was found between tonsil or adenoid size and OSA-18 scores.

Conclusion  This is the largest prospective study that evaluated the long-term effects of the surgery on the QoL of children with SDB using the OSA-18. Our results show adenotonsillectomy has a positive impact in children's QoL.

Management of paediatric obstructive sleep apnoea: A systematic review and network meta-analysis

BACKGROUND

Obstructive sleep apnoea (OSA) affects many children, and adenotonsillar hypertrophy is the most common cause of paediatric OSA.

AIM

Despite the growing treatment options, there is no comprehensive comparison of all interventions. We aimed to compare and rank the effectiveness of various treatments in a network meta-analysis.

DESIGN

Literature was searched from inception to 13 May 2018 for paediatric OSA with adenotonsillar hypertrophy. The outcomes were the changes in apnoea-hypopnea index (AHI), oxyhaemoglobin desaturation index (ODI), and lowest arterial oxygen saturation (SaO₂ ). Frequentist approach to network meta-analysis was used. Treatment hierarchy was summarized according to the surfaces under the cumulative ranking curves.

RESULTS

Fourteen trials comprising 1064 paediatric OSA participants evaluating ten interventions (adenotonsillectomy, adenotonsillectomy + pharyngoplasty, adenotonsillotomy, antimicrobial therapy, steroids, leukotriene receptor antagonists [LTRAs], steroids + LTRAs, rapid maxillary expansion [RME], placebo, and no treatment) were identified for network meta-analysis. In terms of effectiveness in AHI reduction, surgical approach was still the most effective intervention than no treatment. RME was one of the most effective interventions to improve lowest SaO₂ . No comparisons showed statistical significance in reducing ODI.

CONCLUSIONS

Irrespective of the intervention used, complete resolution of OSA was not achieved in most trials.

Clinical Practice Guideline: Tonsillectomy in Children (Update)

OBJECTIVE

This update of a 2011 guideline developed by the American Academy of Otolaryngology-Head and Neck Surgery Foundation provides evidence-based recommendations on the pre-, intra-, and postoperative care and management of children 1 to 18 years of age under consideration for tonsillectomy. Tonsillectomy is defined as a surgical procedure performed with or without adenoidectomy that completely removes the tonsil, including its capsule, by dissecting the peritonsillar space between the tonsil capsule and the muscular wall. Tonsillectomy is one of the most common surgical procedures in the United States, with 289,000 ambulatory procedures performed annually in children <15 years of age based on the most recent published data. This guideline is intended for all clinicians in any setting who interact with children who may be candidates for tonsillectomy.

PURPOSE

The purpose of this multidisciplinary guideline is to identify quality improvement opportunities in managing children under consideration for tonsillectomy and to create explicit and actionable recommendations to implement these opportunities in clinical practice. Specifically, the goals are to educate clinicians, patients, and/or caregivers regarding the indications for tonsillectomy and the natural history of recurrent throat infections. Additional goals include the following: optimizing the perioperative management of children undergoing tonsillectomy, emphasizing the need for evaluation and intervention in special populations, improving the counseling and education of families who are considering tonsillectomy for their children, highlighting the management options for patients with modifying factors, and reducing inappropriate or unnecessary variations in care. Children aged 1 to 18 years under consideration for tonsillectomy are the target patient for the guideline. For this guideline update, the American Academy of Otolaryngology-Head and Neck Surgery Foundation selected a panel representing the fields of nursing, anesthesiology, consumers, family medicine, infectious disease, otolaryngology-head and neck surgery, pediatrics, and sleep medicine.

KEY ACTION STATEMENTS

The guideline update group made strong recommendations for the following key action statements (KASs): (1) Clinicians should recommend watchful waiting for recurrent throat infection if there have been <7 episodes in the past year, <5 episodes per year in the past 2 years, or <3 episodes per year in the past 3 years. (2) Clinicians should administer a single intraoperative dose of intravenous dexamethasone to children undergoing tonsillectomy. (3) Clinicians should recommend ibuprofen, acetaminophen, or both for pain control after tonsillectomy. The guideline update group made recommendations for the following KASs: (1) Clinicians should assess the child with recurrent throat infection who does not meet criteria in KAS 2 for modifying factors that may nonetheless favor tonsillectomy, which may include but are not limited to multiple antibiotic allergies/intolerance, PFAPA (periodic fever, aphthous stomatitis, pharyngitis, and adenitis), or history of >1 peritonsillar abscess. (2) Clinicians should ask caregivers of children with obstructive sleep-disordered breathing and tonsillar hypertrophy about comorbid conditions that may improve after tonsillectomy, including growth retardation, poor school performance, enuresis, asthma, and behavioral problems. (3) Before performing tonsillectomy, the clinician should refer children with obstructive sleep-disordered breathing for polysomnography if they are <2 years of age or if they exhibit any of the following: obesity, Down syndrome, craniofacial abnormalities, neuromuscular disorders, sickle cell disease, or mucopolysaccharidoses. (4) The clinician should advocate for polysomnography prior to tonsillectomy for obstructive sleep-disordered breathing in children without any of the comorbidities listed in KAS 5 for whom the need for tonsillectomy is uncertain or when there is discordance between the physical examination and the reported severity of oSDB. (5) Clinicians should recommend tonsillectomy for children with obstructive sleep apnea documented by overnight polysomnography. (6) Clinicians should counsel patients and caregivers and explain that obstructive sleep-disordered breathing may persist or recur after tonsillectomy and may require further management. (7) The clinician should counsel patients and caregivers regarding the importance of managing posttonsillectomy pain as part of the perioperative education process and should reinforce this counseling at the time of surgery with reminders about the need to anticipate, reassess, and adequately treat pain after surgery. (8) Clinicians should arrange for overnight, inpatient monitoring of children after tonsillectomy if they are <3 years old or have severe obstructive sleep apnea (apnea-hypopnea index ≥10 obstructive events/hour, oxygen saturation nadir <80%, or both). (9) Clinicians should follow up with patients and/or caregivers after tonsillectomy and document in the medical record the presence or absence of bleeding within 24 hours of surgery (primary bleeding) and bleeding occurring later than 24 hours after surgery (secondary bleeding). (10) Clinicians should determine their rate of primary and secondary posttonsillectomy bleeding at least annually. The guideline update group made a strong recommendation against 2 actions: (1) Clinicians should not administer or prescribe perioperative antibiotics to children undergoing tonsillectomy. (2) Clinicians must not administer or prescribe codeine, or any medication containing codeine, after tonsillectomy in children younger than 12 years. The policy level for the recommendation about documenting recurrent throat infection was an option: (1) Clinicians may recommend tonsillectomy for recurrent throat infection with a frequency of at least 7 episodes in the past year, at least 5 episodes per year for 2 years, or at least 3 episodes per year for 3 years with documentation in the medical record for each episode of sore throat and ≥1 of the following: temperature >38.3°C (101°F), cervical adenopathy, tonsillar exudate, or positive test for group A beta-hemolytic streptococcus.

DIFFERENCES FROM PRIOR GUIDELINE

(1) Incorporating new evidence profiles to include the role of patient preferences, confidence in the evidence, differences of opinion, quality improvement opportunities, and any exclusion to which the action statement does not apply. (2) There were 1 new clinical practice guideline, 26 new systematic reviews, and 13 new randomized controlled trials included in the current guideline update. (3) Inclusion of 2 consumer advocates on the guideline update group. (4) Changes to 5 KASs from the original guideline: KAS 1 (Watchful waiting for recurrent throat infection), KAS 3 (Tonsillectomy for recurrent infection with modifying factors), KAS 4 (Tonsillectomy for obstructive sleep-disordered breathing), KAS 9 (Perioperative pain counseling), and KAS 10 (Perioperative antibiotics). (5) Seven new KASs: KAS 5 (Indications for polysomnography), KAS 6 (Additional recommendations for polysomnography), KAS 7 (Tonsillectomy for obstructive sleep apnea), KAS 12 (Inpatient monitoring for children after tonsillectomy), KAS 13 (Postoperative ibuprofen and acetaminophen), KAS 14 (Postoperative codeine), and KAS 15a (Outcome assessment for bleeding). (6) Addition of an algorithm outlining KASs. (7) Enhanced emphasis on patient and/or caregiver education and shared decision making.

Sleep Clinical Record application in Brazilian children and its comparison with Italian children

OBJECTIVE

To apply the Sleep Clinical Record (SCR) to a sample of Brazilian children with sleep complaints, to compare the results with Italian children, and to identify variables that influence phenotype.

METHODS

Brazilian and Italian children, 4-11 years of age and matched for age, gender, obesity, and apnea-hypopnea index and who presented with complaints related to sleep, were selected. The instrument used was the SCR, and the procedure used was full-night cardiorespiratory monitoring.

RESULTS

The sample consisted of 51 Brazilian children and 102 Italian children. Brazilian children presented with oral breathing (55%), tonsillar hypertrophy (69%), Friedman palate position (88%), malocclusion (84%), and OSAS score (Brouilette questionnaire) (55%). The SCR among obese Brazilian children was higher as compared to that in nonobese subjects (obese, 10.84 vs nonobese, 9.13; p = 0.03). In the comparison between Brazilian and Italian children, the total Brazilian SCR was higher than the Italian SCR score (Brazilian SCR, 10.21 ± 7.56; Italian SCR, 8.95 ± 2.55; p = 0.002). The Italian SCR score was influenced by obesity, whereas the Brazilian SCR was influenced by others symptoms (daytime sleepiness, enuresis, nocturnal choking, headache, limb movements).

CONCLUSION

Brazilian children with sleep-disordered breathing show a higher SCR score as compared to Italian children. Obesity and tonsillar hypertrophy, Friedman palate position alteration, and dental malocclusion further influenced the total SCR score among Brazilian children. This may be due to access difficulties in Brazil where children should have more assistance to obtain medical care.

Quality of Life in Youth With Obstructive Sleep Apnea Syndrome (OSAS) Treated With Continuous Positive Airway Pressure (CPAP) Therapy

OBJECTIVE/BACKGROUND

Improvement is sought for youth with obstructive sleep apnea syndrome (OSAS) who have poor quality of life (QoL), which resolves somewhat following treatment. One mitigating factor in improved QoL following treatment may be adherence to the CPAP protocol, which presents a barrier to most youth. This study explored relations between CPAP adherence and QoL in youth with OSAS.

PARTICIPANTS

We recruited 42 youth-caregiver dyads in which youth between the ages of 8 and 16 years were diagnosed with OSAS and required CPAP use as part of their treatment plan.

METHODS

Following diagnosis of OSAS requiring treatment with CPAP therapy, caregivers completed baseline measures of OSAS-specific QoL. The OSAS-specific QoL domains assessed included sleep disturbance, physical symptoms, emotional distress, daytime function, and caregiver concern. Families received routine CPAP care for three months, after which caregivers again completed measures of OSAS-specific QoL. Adherence data were collected from smartcards within the CPAP machine after three months of treatment.

RESULTS

Fifteen youth were adherent to CPAP therapy and 10 were not adherent. CPAP-adherent youth demonstrated significant changes in two domains of OSAS-specific QoL when compared to nonadherent youth: decreased sleep disturbance and decreased caregiver concern.

CONCLUSIONS

CPAP adherence appears to be associated with positive changes in OSAS-specific QoL domains. It will be important for future research and clinical work to examine strategies for improving CPAP adherence in youth with OSAS.

Cost Benefit and Utility Decision Analysis of Turbinoplasty with Adenotonsillectomy for Pediatric Sleep-Disordered Breathing

OBJECTIVES

Use decision analysis techniques to assess the potential utility gains/losses and costs of adding bilateral inferior turbinoplasty to tonsillectomy/adenoidectomy (T/A) for the treatment of obstructive sleep-disordered breathing (oSDB) in children. Use sensitivity analysis to explore the key variables in the scenario.

STUDY DESIGN

Cost-utility decision analysis model.

SETTING

Hypothetical cohort.

SUBJECTS AND METHODS

Computer software (TreeAge Software, Williamstown, Massachusetts) was used to construct a decision analysis model. The model included the possibility of postoperative complications and persistent oSDB after surgery. Baseline clinical and quality-adjusted life year (QALY) parameters were estimated using published data. Cost data were estimated from Centers for Medicare and Medicaid 2018 databases ( www.cms.gov ). Sensitivity analyses were completed to assess for key model parameters.

RESULTS

The utility analysis of the baseline model favored the addition of turbinoplasty (0.8890 vs 0.8875 overall utility) assuming turbinate hypertrophy was present. Sensitivity analysis indicated the treatment success increase (%) provided by concurrent turbinoplasty was the key parameter in the model. A treatment success increase of 3% of turbinoplasty was the threshold where concurrent turbinoplasty was favored over T/A alone. The incremental cost-effectiveness ratio (ICER) of $27,333/QALY for the baseline model was favorable to the willingness-to-pay threshold of $50,000 to $100,000/QALY for industrialized nations.

CONCLUSIONS

The addition of turbinoplasty for children with turbinate hypertrophy to T/A for the treatment of pediatric oSDB is beneficial from both a utility and cost-benefit analysis standpoint even if the benefits of turbinoplasty are relatively modest.
