Evaluation of a multicomponent grading system for obstructive sleep apnoea: the Baveno classification.

ERJ Open Res 2021 Jan 1;7(1). Epub 2021 Mar 1.

Dept of Chest Diseases, Ege University School of Medicine, Izmir, Turkey.

New findings on pathophysiology, epidemiology, and outcome have raised concerns on the relevance of the apnoea-hypopnoea index (AHI) in the classification of obstructive sleep apnoea (OSA) severity. Recently, a multicomponent grading system decision integrating symptomatology and comorbidities (Baveno classification), was proposed to characterise OSA and to guide therapeutic decisions. We evaluated whether this system reflects the OSA population, whether it translates into differences in outcomes, and whether the addition of AHI improves the scheme. Read More
