STS Short-Term Risk Calculator
The Society of Thoracic Surgeons released an updated short-term risk calculator in late 2018 to reflect the latest adult cardiac surgery risk models. You can read about these updated risk models in The Annals of Thoracic Surgery (Part 1—Background, Design Considerations, and Model Development and Part 2—Statistical Methods and Results.)
The STS Short-Term Risk Calculator allows you to calculate a patient’s risk of mortality and morbidities for the most commonly performed cardiac surgeries. It incorporates STS risk models that are designed to serve as statistical tools to account for the impact of patient risk factors on operative mortality and morbidity.
STS risk calculator estimates should be considered as only one of several sources of information in cardiothoracic decision-making and patient counseling. Other sources include but are not limited to the clinical judgment of the surgeon, referring cardiologist, and primary care physician, as well as patient and family preferences. The risk calculator should never be used to exclude patients from surgery based on higher risks associated with a single characteristic (e.g., sex, race, payer).
Step-by-step instructions have been prepared to show you and members of your cardiothoracic surgery team how to access and use the new risk calculator.
