The management of obstructive sleep apnea (OSA) exemplifies the ongoing tension between reductionistic and holistic approaches in modern medicine. While reductionism, exemplified by critical closing pressure (pcrit), arousal threshold, loop gain, and muscle responsiveness (PALM) endotyping, enables precise pathophysiological segmentation, it often overlooks the broader psychosocial context influencing patient behavior. Treatment nonadherence remains a critical challenge, with up to 70% of patients failing to follow prescribed regimens, leading to poorer health outcomes and significant economic burdens. This paper reflects on a 15-year clinical and research journey exploring how to enhance adherence in OSA patients by integrating holistic strategies. Central to this approach is shared decision-making, which prioritizes the patient’s perspective and fosters participatory medicine. Emerging technologies, such as decision aid tools and consumer sleep technologies (CST), offer promising avenues to bridge the reductionism-holism divide. The EU-funded BEAMER project and its B-COMPASS model exemplify efforts to segment patients not only by physiological traits but also by psychological constructs like acceptance and control. Additionally, feedback from validated patient-reported outcome measures (PROMs) via CSTs may empower patients in self-managing their condition. The paper also highlights the role of dynamic modeling of upper airway collapse during sleep, including drug-induced sedation endoscopy (DISE), and the introduction of myofunctional therapy and novel surgical techniques for patients with positive airway pressure nonadherence. Together, these initiatives underscore the potential of combining reductionistic precision with holistic engagement to improve adherence and outcomes in OSA care.
