Key result
A web-based national risk model for thoracic aortic surgery demonstrated good discrimination for 30-day operative mortality (C-index 0.78), with an overall 30-day operative mortality rate of 8.6%.

May aid risk stratification for thoracic aortic surgery in Japan; leaves open external validation and outcome improvement.
Observational (n=4,707)
Yes
A nationwide Japanese database analysis successfully developed a robust risk model for thoracic aortic surgery, demonstrating excellent outcomes despite high patient acuity.
Motomura et al. (2008) conducted an observational in Thoracic aortic surgery (n=4,707). Risk factors for thoracic aortic surgery was evaluated on 30-day operative mortality. A web-based national risk model for thoracic aortic surgery demonstrated good discrimination for 30-day operative mortality (C-index 0.78), with an overall 30-day operative mortality rate of 8.6%.
