A new perspective on OSAS cases with the Baveno classification

Area of Science:

• Sleep Medicine
• Respiratory Medicine
• Clinical Diagnostics

Background:

• The apnea-hypopnea index (AHI) inadequately reflects the clinical picture of Obstructive Sleep Apnea Syndrome (OSAS).
• The Baveno classification was developed for a multicomponent evaluation of OSAS patients.
• There is a need for improved diagnostic tools that capture the clinical complexity of OSAS.

Purpose of the Study:

• To evaluate the practical application of the Baveno classification in clinical settings.
• To compare the Baveno classification with the AHI in diagnosing and grading OSAS.
• To determine if the Baveno classification can identify specific patient subgroups requiring tailored interventions.

Main Methods:

• A prospective study included 378 patients diagnosed with OSAS between January 2021 and June 2022.
• Patients were categorized into four groups (A-D) using the Baveno classification.
• Patients were also stratified into mild, moderate, and severe OSAS based on AHI.

Main Results:

• The Baveno classification divided OSAS cases into comparable groups.
• Oxygen desaturation index (ODI) was higher in Baveno Groups B and D.
• T90 desaturation duration was longer in Baveno Groups C and D, indicating more prolonged oxygen desaturation.
• A notable finding was that 25% of patients with mild OSAS (by AHI) fell into Baveno Group D.

Conclusions:

• The Baveno classification effectively categorizes OSAS patients, including those with mild OSAS who may have significant symptoms or comorbidities.
• This classification facilitates the identification of patients who would benefit from more targeted and effective treatment approaches.
• The Baveno classification is a practical and reasonable tool for clinical application in managing OSAS patients.
