Multicenter Retrospective Observational and

Cross-sectional Analysis

From 01/01/2019 to 12/31/2022

AIM 1: Describe the Practice Patterns across MPOG Institutions

of SGA among Obese patients undergoing General Anesthesia

AIM 2: Evaluate adjusted associations between

clinician- and institution-level SGA practice patterns and

pulmonary complication and 30-day mortality of obese patients
