Factors related to positive airway pressure therapy adherence in children with obesity and sleep-disordered breathing

Caregiver experiences helping children with Down syndrome use positive airway pressure to treat obstructive sleep apnea

BACKGROUND/OBJECTIVE

While positive airway pressure (PAP) is an efficacious intervention for the treatment of obstructive sleep apnea syndrome (OSAS) in children with Down syndrome (DS), implementation and consistent use can be difficult. Caregiver perspectives and experiences using PAP are described with the aim of informing clinical practice.

METHODS

Qualitative semi-structured phone interviews were conducted with 40 caregivers (i.e., mothers) of children with DS and OSAS treated with PAP for at least 6 months. Content analysis was used to identify themes associated with adherence and non-adherence.

RESULTS

Respondents indicated variability in caregiver experience with the adoption of PAP and observed benefits of PAP. Varied experiences were attributed to several themes including accessing supplies, interactions with the medical team and equipment company, and patients' unique needs and behaviors, including the child's willingness and ability to adapt to PAP, sensory sensitivities, keeping the mask on all night, and differences in daytime behavior. Many families reported that desensitization with a reward system and trust within the caregiver-patient relationship were helpful. Caregiver suggestions for improving PAP adherence for families of children with DS included improving communication with the medical team and medical equipment company, emphasizing patience, using visual supports, and social support and education for extended family.

CONCLUSIONS

Although family experiences varied, several actionable strategies by both the medical team and families emerged for improving the experience of and adherence to PAP in children with DS.

Real-world data evaluation of PAP responsiveness in pediatric obstructive sleep apnea

STUDY OBJECTIVES

The use of positive airway pressure (PAP) in children is a complex process determined by multiple factors. There are limited data on the response of the pediatric population to PAP therapy at home. The goal of the study was to examine real-world responses using PAP home monitoring in children with obstructive sleep apnea.

METHODS

The study included PAP therapy data for 195 children aged between 1 month and 18 years with obstructive sleep apnea and polysomnogram baseline study. We collected demographics, clinical variables, and polysomnogram parameters in all study participants. The individual response to PAP therapy was calculated comparing the apnea-hypopnea index (AHI) in the initial polysomnogram with the mean AHI provided by the download of PAP devices. Multivariate models (logistic regression) were used to examine the predictors of positive PAP response defined as a reduction in AHI ≥ 75%.

RESULTS

We found excellent responses to PAP therapy in children (median 85% AHI reduction). However, there was substantial heterogeneity in AHI reductions while on PAP therapy. The best PAP responses were linked to more severe obstructive sleep apnea and higher PAP levels. We also identified that the response to PAP was higher in obese children and lower in males. The best predictive model for individual PAP response was biological sex, obesity, and obstructive AHI ≥ 20 events/h (area under the receiver operating characteristic curve of 0.791).

CONCLUSIONS

Real-world data show that PAP is overall an effective therapy in children but the response is heterogeneous. Obstructive sleep apnea parameters and individual factors can be used to predict individual AHI reductions while on PAP and optimize PAP responses at home.

What’s New in Pediatric Obstructive Sleep Apnea?

Obstructive sleep apnea (OSA) is common children. There is a demand for more family-focused evaluation and novel diagnostic approaches. Drug-induced sleep endoscopy is increasingly being used clinically in children with Down syndrome and other comorbidities. Several studies have examined the association between OSA and other comorbidities during childhood. Therapeutic options for OSA in children remain limited. Recent studies have examined the utility of hypoglossal nerve stimulation in children with Down syndrome. Positive airway pressure has been a mainstay of OSA treatment. Several recent studies have assessed factors associated with adherence. Infants are challenging to treat for OSA.

Adherence to Continuous Positive Airway Pressure Therapy in Pediatric Patients with Obstructive Sleep Apnea: A Meta-Analysis

Introduction

Obstructive sleep apnea (OSA) is a public health problem that affects children. Although continuous positive airway pressure (CPAP) therapy is effective, the CPAP adherence rate in children is varied. This study aimed to evaluate the CPAP adherence rate and factors associated with CPAP adherence in children with OSA using a systematic review.

Methods

The inclusion criteria were observational studies conducted in children with OSA and assessed adherence of CPAP using objective evaluation. The literature search was performed in four databases. Meta-analysis using fixed-effect model was conducted to combine results among included studies.

Results

In all, 34 studies that evaluated adherence rate and predictors of CPAP adherence in children with OSA were included, representing 21,737 patients with an average adherence rate of 46.56%. There were 11 calculations of factors predictive of CPAP adherence: age, sex, ethnicity, body mass index, obesity, income, sleep efficiency, the apnea-hypopnea index (AHI), severity of OSA, residual AHI, and lowest oxygen saturation level. Three different factors were linked to children with adherence and non-adherence to CPAP: age, body mass index, and AHI.

Conclusion

The CPAP adherence rate in children with OSA was 46.56%. Young age, low body mass index, and high AHI were associated with acceptable CPAP adherence in children with OSA.

Pediatric pulmonary year in review 2021: Sleep medicine

Pediatric pulmonology publishes original research, review articles, and case reports on a wide variety of pediatric respiratory disorders. In this article, we summarized the past year's publications in sleep medicine and reviewed selected literature from other journals in this field. We focused on original research articles exploring aspects of sleep-disordered breathing in patients with underlying conditions such as cystic fibrosis, asthma, and sickle cell disease. We also explored sleep-disordered breathing risk factors, monitoring, diagnosis, and treatment; and included recent recommendations for drug-induced sleep endoscopy and ways to monitor and improve PAP adherence remotely.

A social media intervention for the families of young Black men with obstructive sleep apnoea

OBJECTIVE

To address positive airway pressure (PAP) adherence in adolescents diagnosed with obstructive sleep apnoea (OSA) by pilot testing a novel, online, facilitated, peer-support and health education programme for families.

DESIGN SETTING AND METHODS

Families participated in separate Facebook peer-groups (adolescent [n=6] and parent [n=6]) for four weeks, followed by face-to-face interviews. Participants received OSA and PAP educational videos and posts, engaged with questions and polls, and viewed de-identified postings of peer PAP use data.

RESULTS

Adolescent participants were young Black males aged 13-17 years (n=6) with obesity (n=5), severe sleep apnoea (100%) and 4-15 months of prior PAP use. Parent participants were mothers (n=4) and fathers (n=2). Four of six young males increased their mean PAP use during the intervention period. Overall, parents were more engaged with the Facebook group page than adolescents, but interviews revealed the online group/peer-support and education provided was highly regarded and appreciated by families. Parents were particularly appreciative of being involved in care and diagnosis in this way.

CONCLUSION

Results of this pilot trial provide important data regarding intervention design, content, and delivery approaches to be considered in the development of future interventions aiming to engage families and improve adolescent PAP adherence.

Positive Airway Pressure Therapy for Pediatric Obstructive Sleep Apnea

Pediatric obstructive sleep apnea syndrome (OSAS) is a disorder of breathing during sleep, characterized by intermittent or prolonged upper airway obstruction that can disrupt normal ventilation and/or sleep patterns. It can affect an estimated 2–4% of children worldwide. Untreated OSAS can have far reaching consequences on a child’s health, including low mood and concentration as well as metabolic derangements and pulmonary vascular disease. Most children are treated with surgical intervention (e.g., first-line therapy, adenotonsillectomy); however, for those for whom surgery is not indicated or desired, or for those with postoperative residual OSAS, positive airway pressure (PAP) therapy is often employed. PAP therapy can be used to relieve upper airway obstruction as well as aid in ventilation. PAP therapy is effective in treatment of OSAS in children and adults, although with pediatric patients, additional considerations and limitations exist. Active management and care for various considerations important to pediatric patients with OSAS can allow PAP to be an effective and safe therapy in this population.

Management and outcome of extreme pediatric obstructive sleep apnea

OBJECTIVES

Classify post-adenotonsillectomy (AT) respiratory support, identify variables that predict these interventions, and evaluate outcomes in children with extreme obstructive sleep apnea (OSA).

METHODS

Retrospective chart analysis was performed on patients found to have apnea/hypopnea index (AHI) > 100 events/h. Patients with chronic diseases other than obesity were excluded.

RESULTS

Forty-one subjects were studied, average age of 11.4 ± 4.3 years, majority (73.1%) were Hispanic, with a mean total AHI (TAHI) of 128.1 ± 22.9/h. Twenty-eight (68.3%) patients underwent AT. Lower age (P < 0.001), lower BMI Z-score (P < 0.01), higher OAHI (P < 0.05) were associated with having surgery. Eleven out of 28 (39.3%) surgical patients required respiratory support (oxygen or positive airway pressure) postoperatively. Longer % total sleep time S_pO₂ <90% during PSG (P < 0.05) and lower S_pO₂ nadir (P < 0.05) were associated with requiring airway support. No patients experienced mortality, reintubation, or hospital readmission following AT, with majority (71.4%) discharged 1 day post-operatively. Eleven (57.9%) of the 19 patients who had a postoperative PSG had residual OSA, defined as AHI >5 events/h, but there was a significant improvement in TAHI (P < 0.01).

CONCLUSION

Our findings confirm the need for postoperative observation in a controlled setting for patients with extreme OSA undergoing AT. Although at higher risk of needing respiratory support, those patients undergoing AT for extreme OSA did not require re-intubation post-operatively or suffer serious harm. Barring contraindications to AT, surgery may still be a first-line therapy for some children with extreme OSA.
