What this Trial Is About

Researchers are evaluating a new classification system called the Modified Baveno Classification to better understand obstructive sleep apnoea (OSA) in adults newly diagnosed with this condition. The study aims to monitor long-term improvements in both objective and subjective measures related to OSA, including daytime sleepiness and cardiovascular health. This observational cohort study is led by Wissenschaftliches Institut Bethanien e.V and focuses on patients aged 40 years and older. Participants will be categorized into three groups based on the Baveno classification: those for whom OSA-specific treatment is generally not recommended, those for whom treatment should be considered individually, and those for whom treatment is generally recommended. The study does not involve administering treatments but observes the patients over time according to their classification and treatment indications. During the study, participants will be followed for up to 36 months. Researchers will assess changes in daytime sleepiness using the Epworth Sleepiness Scale and monitor office blood pressure. Additional evaluations include cardiovascular events, treatment usage, insomnia severity, sleep length, fatigue, cognitive performance, and overnight oxygen levels. The study tracks these measures throughout the observation period to understand how the classification correlates with patient outcomes and treatment decisions.
