Systematic Screening for Obstructive Sleep Apnea During Preoperative Consultation Using AI-preoperative Agents

Active, not recruiting

• Conditions: Obstructive Sleep Apnea; Preoperative Evaluation

• Registration Number: NCT06779682
• Lead Sponsor: Intelligence Anesthesia

Brief Summary

The goal of this observational study is to evaluate the feasibility of a systematic screening protocol for Obstructive Sleep Apnea (OSA) during preoperative anesthesia consultations in adults aged 50 and older undergoing elective surgery. The main questions it aims to answer are:

* Does the systematic screening protocol increase the proportion of patients identified as being at high risk for OSA compared to standard care?

* What is the impact of systematic screening on postoperative outcomes, including complications, length of stay, and mortality?

Researchers will compare standard care practices (before implementation) to the systematic screening protocol (after implementation) to determine the effect on OSA detection rates and clinical outcomes.

Participants will:

* Complete the STOP-BANG questionnaire during their anesthesia consultation.

* (Optional) Have a facial photograph taken to analyze morphometric characteristics that may correlate with OSA risk.

* Be referred for further diagnostic testing if identified as high-risk for OSA.
