Quality, Research & Patient Safety

Quality, research, and patient safety initiatives are vital components of The Society of Thoracic Surgeons efforts to help members provide the highest quality of care for patients undergoing cardiothoracic surgery.


The STS National Database and its quality assessment activities, development of nationally recognized quality measures, and quality improvement initiatives are all built on the foundation of more than 5.8 million surgical records. 

The STS National Database, a Qualified Clinical Data Registry (QCDR) for the Merit-Based Incentive Payment System (MIPS)can report quality measures on behalf of individual surgeons participating in the Adult Cardiac Surgery Database.

In addition to providing the STS National Database, the Society has partnered with the American College of Cardiology Foundation to provide the STS/ACC TVT Registry™ , which focuses on patients undergoing aortic and mitral transcatheter valve replacement and repair procedures. This registry includes longitudinal follow up of outcomes after hospital discharge, including vital status and quality of life.


Research activities, based on STS National Database data, to date have resulted in more than 100 peer-reviewed publications in the scientific literature and have significantly advanced knowledge in cardiothoracic surgery.

Patient Safety

STS, committed to optimizing patient safety in cardiothoracic surgery, also provides resources and education that promote leadership and foster teamwork to help surgeons create patient-centered environments and improve their practices.

Public Reporting

The Society is leading the way in public reporting through its collaboration with Consumers Union and its STS Public Reporting Online initiative, available to participants in the STS National Database.
