Transition to Adult Care for Obstructive Sleep Apnea

Positive Airway Pressure Usage in Youth with Obstructive Sleep Apnea Following Transition to Adult Health Care

BACKGROUND

There is increasing prevalence of moderate to severe obstructive sleep apnea (OSA) in adolescents, the majority of whom receive treatment with positive airway pressure (PAP). Adherence to PAP is sub-optimal in adolescents with OSA. Moreover, the impact of transition from pediatric to adult healthcare system on PAP adherence is unknown. This is relevant as the transition period is a time of increased stress for youth with chronic illnesses.

RESEARCH QUESTION

Does PAP adherence decrease during the 1-year transition period from pediatric to adult healthcare system in those with OSA?

STUDY DESIGN AND METHODS

Youth previously diagnosed with persistent OSA and treated with PAP in a large academic center (Toronto, Canada) between 2017 and 2019 were enrolled on transfer from the pediatric to adult sleep clinic and followed at 12 months. Mixed-effects linear regression models were used to investigate the effect of time since the transfer on objective PAP adherence with adjustment for confounders.

RESULTS

Among the 45 enrolled participants, 42.2% were female, the median age was 18 years (interquartile range [IQR]: 17-18), median BMI was 30.3 (IQR: 24.0-37.1), and the median apnea-hypopnea index (AHI) was 17.8 events/hour (11.8-30.7). In univariate analysis, we observed a significant reduction in the 12-month average PAP usage in days used at follow-up compared to PAP use at the time of enrolment: median of 5.0 hours/day (IQR: 1.3-8.0) vs 2.6 hours/day (0.0-6.4), p < 0.0001. Following adjustment for age, level of education, employment status and living arrangement, the 12-month average PAP usage in days remained significantly decreased at follow-up compared to at the time of enrolment: change in hours of -1.14; 95% CI -2.27 to -0.01.

INTERPRETATION

Among youth with OSA treated with PAP, there is a clinically significant reduction in PAP adherence over the first year during the transition from pediatric to adult health care.

The role of the dentist in the diagnosis and management of pediatric obstructive sleep apnea

The objective of this article is to review the role of the dentist in the early diagnosis of pediatric obstructive sleep apnea (OSA) and to provide an in-depth review of the best evidence-based practices available to treat and/or to refer these patients for intervention.

Material and methods

A narrative review was performed using indexed data bases (PubMed, Medline, EMBASE, OVID, Scopus and Cochrane) up to year 2020, and approximately 1000 articles were reviewed. The articles included were those with the best information provided.

Results

Detailed review of the literature suggests that the role of the dentist has been redefined owing to their expertise in the orofacial region. Every patient consulting a dental practice is not merely a dental patient; he/she also requires a comprehensive medical review. The role of the dentist is pivotal in pediatric patients once diagnosed with OSA; as the patients grow, growth modification can be achieved, and future management will be easier. Initiating dental treatments during growth can benefit patients two-fold, saving them from malocclusion, and intervening in orofacial structural growth can help to avoid cumbersome treatments, such as CPAP and various surgeries. Proper diagnosis and management of systemic illnesses can prevent compromised quality of life, delays in treatment, morbidity and, in some cases, mortality.

[Atypical depression as a risk factor for obstructive sleep apnea syndrome in young adults]

OBJECTIVES

In the literature, several studies have investigated the particular relationship between major depression and obstructive sleep apnoea syndrome (OSAS). However, most of these studies have focused primarily on middle-aged to elderly individuals (≥40 years) which means that this problem has been little studied in young adults (<30 years). Nevertheless, in young adults the prevalence of major depression (particularly its atypical subtype) is not negligible, which seems to justify carrying out additional investigations in order to allow a better understanding of the potential role played by major depression in the pathophysiology of OSAS in this particular subpopulation. The aim of this study was therefore to empirically investigate the prevalence of OSAS in young adults and to study the risk of OSAS associated with major depression in this particular subpopulation.

METHODS

Polysomnographic and demographic data from 264 young adults were collected from the Erasme Hospital Sleep Laboratory (Brussels, Belgium) database to enable our analyses. During their two-night stay (including a first night of habituation and a night of polysomnography) at the Sleep Laboratory, these individuals underwent a complete somatic assessment (including blood test, electrocardiogram, daytime electroencephalogram and urinalysis), a systematic psychiatric assessment by a unit psychiatrist and an assessment of their complaints related to sleep. These different steps made it possible to systematically diagnose all somatic pathologies, psychiatric disorders according to the diagnostic criteria of the DSM-IV-TR and sleep pathologies according to the diagnostic criteria of the AASM. This allowed the selection of young adults included in our study based on our inclusion and exclusion criteria. Polysomnographic recordings from our Sleep Laboratory were visually scored according to AASM criteria. An obstructive sleep apnoea-hypopnoea index ≥5/hour was used for the diagnosis of OSAS. At the statistical level, in order to allow our analyses, we subdivided our sample of young adults into two groups: a control group without OSAS (n=215) and a patient group with OSAS (n=49). After checking the normal distribution of our data, normally distributed data were analysed with t-tests whereas asymmetrically or dichotomously distributed data were analysed with Wilcoxon tests or Chi² tests. Univariate regression models were used to study the risk of OSAS associated with major depression (categorized: absent, typical, atypical) in young adults and potential confounding factors. In multivariate regression models, the risk of OSAS associated with major depression (categorized: absent, typical, atypical) in young adults was adjusted only for confounding factors significantly associated with OSAS during univariate analysis. These confounding factors were introduced in a hierarchical manner in the various multivariate regression models constructed.

RESULTS

The prevalence of OSAS in our population of young adults was 18.6 %. During univariate analyses, atypical depression [OR 2.51 (95% CI 1.18-5.32), p-value=0.014], male gender [OR 4.53 (95% CI 2.20-9.34), P-value <0.001], presence of snoring [OR 2.51 (95% CI 1.33-4.75), P-value=0.005], presence of at least one cardio-metabolic alteration [OR 2.26 (95% CI 1.19-4.28), P-value=0.012], body mass index>30 kg/m² [OR 4.55 (95% CI 2.07-10.03), P-value <0.001] and ferritin ≥150 μg/L [OR 3.28 (95% CI 1.69-6.36), P-value<0.001] were associated with increased risk of OSAS in our population of young adults. After adjusting for these major confounding factors associated with OSAS (gender, body mass index, cardio-metabolic alterations, ferritin level, and snoring) in the four models studied, multivariate regression analyses confirmed that unlike typical depression, atypical depression [OR 3.09 (95% CI 1.26-7.54), P-value=0.019] was a risk factor for OSAS in young adults.

CONCLUSIONS

In our study, we demonstrated that the prevalence of OSAS was 18.6 % in young adults referred to the Erasme Hospital Sleep Laboratory. In addition, we have shown that unlike typical depression, atypical depression was associated with an increased risk of OSAS in young adults, which seems to justify more systematic research of this pathology in young adults suffering from atypical depression in order to allow the establishment of adapted therapeutic strategies and avoid the negative consequences associated with the co-occurrence of these two pathologies.

Continue the Conversation: A Complex Care Pediatrician's Perspective on Improving Healthcare Transitions for Pediatric Neurology Patients

Inadequate preparation for transition to adult-oriented systems of care leads to gaps in treatment and can result in poor health outcomes for youth with special healthcare needs. Coordination between primary care and specialists must occur at multiple levels of organizations to improve transition for youth with neurological disorders. This review focuses on the transition process from the pediatrician's perspective, highlights common obstacles, addresses the unique needs of youth with intellectual disabilities, reviews relevant guidelines, and discusses emerging transition strategies. Key recommendations include defining the roles of the different healthcare providers and using multidisciplinary collaboration to overcome limited resources.
