What is the relationship between hospital volume and outcomes for coronary artery bypass graft surgery?
The correlation between hospital volume and outcomes for coronary artery bypass graft surgery (CABG) has been extensively studied. Studies have shown that higher hospital volume is associated with improved outcomes, including lower mortality rates, lower complication rates, and shorter lengths of stay. Furthermore, research has suggested that the benefits of higher hospital volume for CABG may be limited to patients at high risk, and there may be a diminishing returns effect, where increasing volume beyond a certain point does not necessarily lead to further improvements in outcomes. Overall, higher hospital volume appears to have a positive association with outcomes for CABG.
