Hospital Case Volume Health Care Providers and Mortality in Patients Undergoing Coronary Artery Bypass Grafting: a Nationwide Cohort Study in South Korea

摘要

Our South Korean population-based cohort study showed that a higher annual hospital case volume was associated with a lower 90-day mortality after isolated coronary artery bypass grafting (CABG). Additionally, a higher overall specialty physician volume was independently associated with a lower 90-day mortality. We reported cut-off values of ≥65 and ≥18 for the annual case volume of CABG and the total number of overall specialty doctors per 100 hospital beds, respectively, for achieving better outcomes after CABG.
