The ASCERT risk calculator estimates the long-term probability of survival following an isolated CABG surgical procedure in patients 65 years and older, using inputs on 31 patient demographic and clinical variables, such as age, weight, creatinine level, smoking history, and number of diseased vessels. The user provides the observed values for each of the variables listed and results are displayed over a series of nine points in time, ranging from 90 days to 7 years.
The calculator is based on a risk model derived from linking STS Adult Cardiac Surgery Database data to Centers for Medicare and Medicaid Services MEDPAR data as part of the STS-ACC ASCERT grant.
