The Society offers two risk calculators that cardiothoracic surgeons can use in their practices.
STS Short-Term Risk Calculator
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. The Risk Calculator 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.
The ASCERT Long-Term Survival Probability Calculator for Isolated CABG allows a user to calculate survival probability following isolated coronary artery bypass grafting surgery in patients 65 years and older. The calculator incorporates a risk model derived from linking STS Adult Cardiac Surgery Database data (version 2.52) to Centers for Medicare & Medicaid Services MEDPAR data as part of the STS-ACC ASCERT grant.
