Key result
Undergoing CABG or PCI in a high-volume hospital was associated with lower in-hospital mortality compared to low-volume hospitals (PCI OR 0.87, 95% CI 0.83-0.91; CABG OR 0.85, 95% CI 0.79-0.92).
Why the study?
Does treatment in a high-volume hospital reduce in-hospital mortality in patients undergoing CABG or PCI?
Meta-Analysis (n=2,793,332)
Yes
Does treatment in a high-volume hospital reduce in-hospital mortality in patients undergoing CABG or PCI?
Effect estimate: OR 0.87 (PCI); OR 0.85 (CABG) (95% CI 0.83-0.91 (PCI); 0.79-0.92 (CABG))
Patients undergoing CABG or PCI in high-volume hospitals have significantly lower in-hospital mortality compared to those treated in low-volume hospitals, an effect that has not attenuated over time.

Supports volume-based referral consideration for CABG/PCI; confirms persistent association in updated meta-analysis of observational data.
Post et al. (2010) conducted a meta-analysis in Coronary interventions (CABG or PCI) (n=2,793,332). High-volume hospital vs. Low-volume hospital was evaluated on In-hospital mortality (OR 0.87 (PCI); OR 0.85 (CABG), 95% CI 0.83-0.91 (PCI); 0.79-0.92 (CABG)). Undergoing CABG or PCI in a high-volume hospital was associated with lower in-hospital mortality compared to low-volume hospitals (PCI OR 0.87, 95% CI 0.83-0.91; CABG OR 0.85, 95% CI 0.79-0.92).
