Key result
Performing coronary artery bypass surgery on high-risk patients did not adversely affect risk-adjusted mortality rates compared to routine patients (2.94% vs 3.02%, not statistically significant).

High-risk CABG may proceed without harming risk-adjusted metrics; Level 3 data leaves open generalizability and causality.
Observational
Yes
Does performing coronary artery bypass surgery on high-risk patients adversely affect the risk-adjusted mortality rates for surgeons and hospitals compared to low-risk patients?
Absolute Event Rate: 2.94% vs 3.02%
p-value: p=not statistically significant
Operating on high-risk CABG patients does not adversely affect the risk-adjusted mortality performance metrics for hospitals and surgeons in New York State.
Hannan et al. (1997) conducted an observational in Coronary artery bypass graft surgery. Coronary artery bypass surgery on high-risk patients vs. Coronary artery bypass surgery on low-risk patients was evaluated on Risk-adjusted mortality rate (p=not statistically significant). Performing coronary artery bypass surgery on high-risk patients did not adversely affect risk-adjusted mortality rates compared to routine patients (2.94% vs 3.02%, not statistically significant).
