Biomarkers and Risk Models in Cardiac Surgery
Early risk models in cardiac surgery focused exclusively on coronary artery bypass grafting surgery (CABG), using pre-procedural variables to estimate the likelihood of in-hospital or 30-day mortality. These models were initially developed to assess provider performance, but they have subsequently been used for patient counseling, shared decision-making, and a variety of other applications. For provider profiling, the expected outcomes for all patients of a given hospital or surgeon, estimated from regional or national benchmarks, are aggregated to calculate the expected outcomes for their overall practice. These expected rates are compared with the observed outcomes to calculate standardized mortality ratios or rates.
