A Global Comparison of Anatomic Risk Factors and Their Relationship to Obstructive Sleep Apnea Severity in Clinical Samples

Many preoperative OSA screening scores have been developed and validated (STOP-Bang, P-SAP, DES-OSA, …). To the best of our knowledge, none of them include ethnicity. In this very interesting study, the authors confirmed that gender has to be included in OSA preoperative screening, and very interestingly, they have demonstrated we must consider ethnicity in this preoperative screening. They compared the following ethnicities: Caucasians, African Americans, Asians, and South Americans. South American appears to have the highest risk of developing OSA. This information is important for the development or improvement of future preoperative OSA screening scores.
