Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this observational study is to evaluate a new classification system for obstructive sleep apnoea in patients with newly diagnosed obstructive sleep apnoea and monitor for long-term objective and subjective improvement.

weak treatment indication

Patients with obstructive sleep apnoea (OSA) for whom OSA-specific treatment is generally not recommended according to the Baveno classification

No interventions assigned to this group

intermediate treatment indication

Patients with obstructive sleep apnoea (OSA) for whom OSA-specific treatment should be considered based on individual assessment according to the Baveno classification

No interventions assigned to this group

strong treatment indication

Patients with obstructive sleep apnoea (OSA) for whom OSA-specific treatment is generally recommended according to the Baveno classification

No interventions assigned to this group

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Adult patient ≥40 years at the time of signed informed consent
2. Diagnosis of predominant obstructive sleep apnoea with a total apnoea-hypopnoea index of ≥5 /h based on a diagnostic sleep study (polysomnography or polygraphy, as per local standard). Predominant obstructive sleep apnoea defined as ≥70% of respiratory events classified as obstructive.
3. Signed and dated written informed consent in accordance with ICH-GCP and applicable local regulations

Exclusion Criteria

1. \>30% central respiratory events (apnoeas and hypopnoeas) within the diagnostic sleep study
2. Established sleep apnoea treatment within the last 12 months before study inclusion (positive airway pressure, mandibular advancement device, positional therapy)
3. Use, or need for chronic use, of any non-invasive positive pressure ventilation device
4. Participation in an interventional study and/or receiving investigational treatment(s)
5. Significant disease or condition, which, in the opinion of the investigator, may interfere with study procedures or cause concern regarding the patient's ability to participate in the study
6. Patients not expected to comply with the protocol requirements or not expected to complete the trial as scheduled (e.g. chronic alcohol or drug abuse or any other condition that, in the investigator's opinion, makes the patient an unreliable trial participant)
