This review outlines the current state of the literature regarding the effect of hospital emergency general surgery (EGS) volume on patient- and hospital-based outcomes. Recent evidence suggests that higher volume centers offer superior performance with respect to in-hospital mortality, a phenomenon that becomes more pronounced with increasingly complex or high-risk operations. High-quality studies have demonstrated that hospital EGS volume is correlated with lower in-patient mortality. This finding has been demonstrated across individual EGS operations with increasing case complexity requiring higher volumes to demonstrate improved outcomes. There remains a knowledge gap in determining what specific factor of volume, such as surgeon volume or system experience or possibly a combination of the two, best explains the observed improvement in outcomes. |
