Taiwan Obstructive Sleep Apnea Cohort

Clinical Features of Obstructive Sleep Apnea Patients With Different Phenotypes

Observational China Medical University Hospital · NCT07302685

This project will recruit 7,000 people with obstructive sleep apnea in Taiwan to see if PSG-derived endotypes and clinical features predict future health outcomes by linking sleep tests with national health records.

What this trial studies

The study will prospectively enroll 7,000 patients referred to the China Medical University Hospital sleep center from 2020–2027 and collect full-night polysomnography and clinical data, which will be linked to the National Health Insurance Research Database. Polysomnography parameters will be used to derive endotypic traits such as measures of airway collapsibility, loop gain, arousal threshold, and muscle compensation. The investigators will examine associations between clinical features, PSG-based endotypes, and subsequent health outcomes recorded in the national database. A subset of participants will be invited for additional testing including lung function, blood serum tests, arterial blood gas, and cognitive assessments to provide complementary phenotyping.

Who should consider this trial

Good fit: Adults referred by physicians to the China Medical University Hospital sleep center with suspected or diagnosed obstructive sleep apnea who can complete at least six hours of polysomnography are ideal candidates.

Not a fit: Patients who are not referred to this center, cannot complete the required six hours of PSG, or cannot consent to linkage with national health records are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, this work could help identify patient-specific OSA endotypes that predict complications and guide more personalized treatment approaches.

How similar studies have performed: PSG-based endotyping has shown promise in smaller cohorts for characterizing OSA mechanisms, but large-scale prospective linkage to a national health database is relatively novel.
