Ascension Saint Thomas Hospital West achieves elite three-star rating for cardiovascular excellence in aortic valve replacement and coronary artery bypass grafting by The Society of Thoracic Surgeons

Ascension Saint Thomas Hospital West has earned a distinguished three-star rating from The Society of Thoracic Surgeons (STS) for its patient care and outcomes in aortic valve replacement (AVR) combined with coronary artery bypass grafting (CABG), and in isolated coronary artery bypass grafting (CABG) procedures. The three-star rating, which denotes the highest category of quality, places Ascension Saint Thomas Hospital West among the elite for AVR+CABG surgery and heart bypass surgery in the United States and Canada.

The STS star rating system is one of the most sophisticated and highly regarded overall measures of quality in health care, rating the benchmarked outcomes of cardiothoracic surgery programs in the United States and Canada. The star rating is calculated using a combination of quality measures for specific procedures performed by an STS Adult Cardiac Surgery Database participant.

Historically, approximately 4%–7% of participants receive the three-star rating for AVR+CABG surgery and 20% for isolated CABG surgery. The latest analysis of data for AVR+CABG surgery and isolated CABG surgery covers a 3-year period, from July 2020 to June 2023, and includes 982 cardiac surgery programs analyzed.

“The Society of Thoracic Surgeons congratulates STS National Database participants who have received three-star ratings,” said David M. Shahian, MD, chair of the Task Force on Quality Measurement. “Participation in the Database and public reporting demonstrates a commitment to quality improvement in health care delivery and provides patients and their families with meaningful information to help them make informed decisions about health care.”

The STS National Database was established in 1989 as an initiative for quality improvement and patient safety among cardiothoracic surgeons. The Database includes four components: the Adult Cardiac Surgery Database (ACSD), the Congenital Heart Surgery Database (CHSD), the General Thoracic Surgery Database (GTSD), and the mechanical circulatory support database (Intermacs). The STS ACSD houses approximately 6.9 million surgical records and gathers information from more than 3,800 participating physicians, including surgeons and anesthesiologists from more than 90% of hospitals that perform heart surgery in the US. STS public reporting online enables STS ACSD participants to voluntarily report to each other and the public their heart surgery scores and star ratings.
