Does a continuous quality improvement program using risk-adjusted outcomes improve operative mortality and morbidity in patients undergoing cardiac surgery?
A large-scale continuous quality improvement program using risk-adjusted outcomes in VA cardiac surgery is feasible and associated with a trend toward decreased risk-adjusted operative mortality.
