Abstract

Background: Cardiogenic shock (CS) is associated with a high degree of morbidity and mortality. Although outcomes of CS are well studied, outcomes across patients with different types of health insurance are not known. This study aimed to compare the outcomes of patients admitted with CS in Medicare beneficiaries versus Medicaid insurance using the National Inpatient Sample (NIS) database. Methods: We conducted a retrospective cohort analysis using the NIS database from 2016-2021 utilizing ICD-10-CM codes to identify patients with CS classified based on payer status. We included baseline demographic characteristics and compared in-hospital outcomes. Propensity score matching (PSM) and Pearson’s Chi-squared test was applied to the matched cohorts to compare outcomes between Medicare and Medicaid patients. Results: Our analysis included 10,635 patients admitted with CS (8,655 with Medicare, 1,980 with Medicaid). After PSM, patients with Medicaid were found to have significantly higher in-hospital mortality (p<0.05) and acute kidney injury (p<0.05) than patients with Medicare. There were no significant differences in the two groups for acute stroke, sudden cardiac arrest, pulmonary embolism, sepsis and cardiac arrhythmias (p>0.05). [Formula presented] Conclusion: Medicare beneficiaries with CS had better clinical outcomes in terms of In-hospital mortality and acute kidney Injury compared to patients with Medicaid. Additional studies elucidating the reasons behind disparities in CS outcomes are needed. Categories: CORONARY: Hemodynamic Support, Cardiogenic Shock and Cardiac Arrest
