Patient-Centered Therapy for Obstructive Sleep Apnea: A Review

Knowledge, attitudes, and practices of physicians regarding multidisciplinary treatment of obstructive sleep apnea: a cross-sectional study

To investigate physicians' knowledge, attitudes, and practices (KAP) regarding the multidisciplinary treatment of Obstructive Sleep Apnea (OSA). A multicenter cross-sectional study was conducted in May 2024, enrolling physicians from southwestern China. The study collected demographic data and assessed KAP through self-administered questionnaires, with the respiratory and otolaryngology departments defined as relevant departments. A total of 329 valid questionnaires were collected. Of these respondents, 173 (52.6%) were female, and 114 (34.7%) had participated in multidisciplinary OSA-related training. The mean scores for knowledge and attitudes were 24.61 ± 8.27 (possible range: 0-34) and 39.99 ± 4.34 (possible range: 10-50), respectively. Practice scores of the physicians in departments directly and indirectly involved in OSA treatment averaged 24.28 ± 4.70 and 21.28 ± 4.24 (possible range: 6-30), respectively. Structural equation modeling results indicated that in departments directly related to OSA, knowledge had a significant positive effect on both attitudes (β = 5.53, P < 0.001) and practices (β = 5.8, P < 0.001). For departments indirectly related to OSA, knowledge had a significant positive effect on attitudes (β = 5.41, P < 0.001). Physicians showed adequate knowledge and attitudes toward OSA treatment; targeted education is recommended to enhance consistency in practices across departments.

Management of Paediatric Obstructive Sleep Apnoea: From a Multidisciplinary to an Interdisciplinary Care Model

The objective of this study is to offer a comprehensive overview of paediatric obstructive sleep apnoea (OSA), a prevalent condition characterised by intermittent upper airway obstruction that impairs both ventilation and sleep. The design of the study was a literature review using an electronic search. The study extensively reviews the pathophysiology, epidemiology, sequelae and diagnostic approaches of paediatric OSA. It highlights the role of various healthcare professionals in the management of this disorder, with each specialist providing unique contributions to the diagnosis, treatment and ongoing management of OSA. The current state of sleep teams managing OSA is multidisciplinary, including sleep physicians, pulmonologists and otolaryngologists (ENT surgeons), each contributing distinct expertise. This review contrasts a multidisciplinary approach, which relies on separate expert contributions, with an interdisciplinary model that emphasises integrated, collaborative decision-making for comprehensive, patient-centred care. This review focuses on the interactions between dental and medical professionals, as other papers will provide more detailed insights into the roles of other specialists, such as myofunctional therapists, nutritionists and others. In conclusion, the evolution from a multidisciplinary to an interdisciplinary care model marks a significant development in clinical practice, enhancing cooperation and shared decision-making among healthcare professionals, thereby improving the quality of life for paediatric patients with OSA.

Impact of weight loss and lifestyle intervention on vitamin D in men with obstructive sleep apnea: The INTERAPNEA trial

INTRODUCTION

Vitamin D deficiency is commonly found among patients with obstructive sleep apnea (OSA). We aimed to determine the effect of an eight-week interdisciplinary weight loss and lifestyle intervention on circulating vitamin D levels in patients with moderate-to-severe OSA.

METHODS

89 men were assigned to a usual-care group (n = 49) or an 8-week interdisciplinary weight loss and lifestyle intervention combined with usual-care (n = 40). Evaluations were conducted at baseline, intervention endpoint (i.e., 8 weeks), and 6 months post-intervention. Serum 25-hydroxyvitamin D (25(OH)D) was determined using a chemiluminescence immunoassay. Sleep (i.e., sleep efficiency, apnea-hypopnea index [AHI], and oxygen desaturation index) and body weight and composition (i.e., fat mass, and visceral adipose tissue) variables were also determined.

RESULTS

Serum 25(OH)D concentrations showed an insufficient vitamin D status at baseline, which significantly increased (all p ≤ 0.034) at intervention endpoint (19 %) and at 6 months after intervention (45 %) in the intervention group to the point of potentially resolving vitamin D deficiency. Higher serum 25(OH)D concentrations were related to increased sleep efficiency and reduced AHI, oxygen desaturation index, and body weight and composition variables (all p < 0.001) from baseline to 6 months and from 8 weeks to 6 months after intervention. These results were also noted from baseline to 8 weeks, except for body composition (all p ≤ 0.007).

CONCLUSION

The intervention improved and potentially resolved vitamin D deficiency. Together with the improvement of adverse sleep patterns and body composition parameters, it may be considered as a promising approach in the treatment of OSA.
