What are the recommendations for using outcomes or volume as CABG quality measures?
Class I: All cardiac surgery programs should participate in a state, regional, or national clinical data registry and should receive periodic reports of their risk-adjusted outcomes. Class IIa: When credible risk-adjusted outcomes data are not available, volume can be useful as a structural metric of CABG quality. Class IIb: Affiliation with a high-volume tertiary center might be considered by cardiac surgery programs that perform fewer than 125 CABG procedures annually.
