Highest Heart Bypass Surgery Rating

The cardiothoracic surgical team at Mercy Hospital South has earned a three-star rating from the Society for Thoracic Surgeons (STS), which is the organization’s highest rating for quality patient care and outcomes. Less than 15% of hospitals in the United States and Canada earn this distinction.

The STS rating system is a sophisticated, highly regarded measure of quality in health care. The organization benchmarked outcomes for coronary artery bypass grafting (CABG) procedures at Mercy South. Those benchmarks include length of stay, readmission rates, blood product usage, length of ventilator usages, medication administration, and post-operative complication rates.
