Key result
Higher monthly surgeon volume linked to ~7% lower risk-adjusted in-hospital mortality.
Why the study?
Does the individual surgeon or anesthesiologist and their caseload volume impact in-hospital mortality in patients undergoing major cardiac surgery?

Does the individual surgeon or anesthesiologist and their caseload volume impact in-hospital mortality in patients undergoing major cardiac surgery?
In cardiac surgery, patient risk profile overwhelmingly determines in-hospital mortality, though low surgeon volume remains a significant risk factor.
Answers are grounded in this paper and cite their sources.
Patient risk factors dominate cardiac surgery mortality; leaves open whether surgeon volume thresholds merit targeted quality initiatives.

Papachristofi et al. (2013) conducted a cohort in Cardiac surgery (n=18,426). Surgeon and anesthesiologist monthly caseload volume was evaluated on in-hospital death (OR 0.93, 95% CI 0.87-0.98). Patient risk profile primarily determined in-hospital mortality, while low monthly surgeon volume was associated with higher risk-adjusted mortality.
