Outcome Improvement and Cost Reduction in an Increasingly Morbid Cardiac Surgery Population

Two studies assessed initiatives to improve the quality and the cost-effectiveness of cardiac surgery. The first evaluated a system for access and stabilization (SAS), with coronary stabilization, and a clinical effectiveness quality initiative (CEQI) in off-pump coronary artery bypass grafting. The SAS + CEQI cohort showed significantly lower mortality, a lower percentage of patients requiring prolonged ventilation, and a shorter mean postoperative length of hospital stay than the pre-SAS cohort who underwent on-pump coronary artery bypass grafting. The second study assessed the potential for noninvasive cerebral oximetry to reduce strokes related to all cardiac surgery by optimizing cerebral oxygen delivery. The incidence of permanent stroke was significantly lower in the cerebral oximetry group than in an earlier control group in which cerebral oximetry was not used, despite the fact that the study group had a significantly greater number of patients in New York Heart Association classes III and IV.
