Abstract:
This analysis assesses disparities in predicted postoperative outcomes for isolated coronary
artery bypass grafting (CABG) surgery using the Society of Thoracic Surgeons (STS) Shortterm/
Operative Risk Calculator. Predictions are modeled on a ‘control’ patient: a a60-yearold
undergoing their first cardiovascular surgery, with urgent status, three-vessel coronary
artery disease, and no comorbidities. The variables examined include sex, race, and insurance
status (Medicaid vs. commercial insurance). Two primary risk metrics are evaluated: combined
morbidity and mortality, and the probability of a prolonged hospital stay (defined as
exceeding 14 days). Findings indicate that Medicaid-covered patients consistently face higher
projected risks of morbidity, mortality, and extended hospital stays compared to those with
commercial insurance, across all demographic subgroups. These disparities suggest a need
for further investigation into systemic and institutional factors contributing to such inequities.
For instance, the association between Medicaid coverage and prolonged hospitalization may
be partially driven by financial incentives tied to extended inpatient care, potentially at the
expense of increased patient exposure to hospital-acquired infections. Additionally, female
patients demonstrate higher projected morbidity and mortality risks than their male counterparts
of the same race, independent of insurance status. The most vulnerable subgroup identified
comprises Asian and Black/African American females with Medicaid coverage. These
results underscore the impact of intersecting demographic and socioeconomic variables on
surgical risk profiles and highlight the urgent need for equity-centered approaches in preoperative
risk assessment and healthcare delivery.
