Key result
Hospitals not meeting Leapfrog Group volume thresholds for specific procedures were associated with significantly higher odds of in-hospital mortality compared with those meeting thresholds (P < 0.05).
Why the study?
Does treatment at hospitals meeting procedure-specific volume thresholds reduce in-hospital mortality in patients undergoing CABG, PCI, AAA, PAN, or ESO?
Observational
Yes
Does treatment at hospitals meeting procedure-specific volume thresholds reduce in-hospital mortality in patients undergoing CABG, PCI, AAA, PAN, or ESO?
p-value: p=< 0.05
The association between higher hospital procedure volume and lower in-hospital mortality is specific to the procedure being performed, rather than a reflection of overall hospital surgical volume.

Supports volume-based referral for these procedures; leaves open causality versus confounding in observational data.
Allareddy et al. (2007) conducted an observational in Patients undergoing CABG, PCI, AAA, PAN, or ESO. Hospital procedure volume not meeting Leapfrog Group thresholds vs. Hospitals meeting Leapfrog Group volume thresholds was evaluated on In-hospital mortality (p=< 0.05). Hospitals not meeting Leapfrog Group volume thresholds for specific procedures were associated with significantly higher odds of in-hospital mortality compared with those meeting thresholds (P < 0.05).
