The primary motivation in conducting this study is to conduct the implementation science, i.e., formalize and train, and retrain if needed, anesthesia providers in the standard practice of titrating infusion rate to effect and clinically evaluate the effect of race and ethnicity on propofol monotherapy sedation during GI endoscopy. The ultimate goal is to make it less likely that patients from races known to be sensitive to propofol experience inadvertent overdosing.
