STS score
Also written as: STS — Society of Thoracic Surgeons
Society of Thoracic Surgeons risk prediction model used to estimate mortality and morbidity for cardiac surgical procedures.
Full Definition
The STS score is a validated risk stratification tool developed by the Society of Thoracic Surgeons that calculates predicted operative mortality and major morbidity for cardiac surgical procedures. The scoring system incorporates patient demographics, comorbidities, and procedural factors to generate risk-adjusted outcomes. It is widely used in clinical decision-making, patient counseling, and quality assessment in cardiovascular surgery. The score helps determine appropriateness for surgical intervention versus alternative treatments.
Usage
Usage note: Always express as percentage when reporting numerical values.
