C-55 | In Hospital Outcomes of Coronary Artery Bypass Graft in patients with a history of COVID 19 infection: An Analysis of the 2020 National Inpatient Sample

COVID-19 has been associated with a high burden of cardiovascular morbidity and mortality. We evaluated the outcomes of coronary artery bypass graft (CABG) hospitalizations in patients with COVID-19 infection using the National Inpatient Sample(NIS) 2020 database. We identified hospitalization with a diagnosis of COVID-19 from the NIS 2020 database. Using the International classification for the 10th deviation (ICD–10) code U07.1. Within this population, we looked for hospitalized patients with CABG procedure. Our outcomes of interest were the length of hospitalization (LOS), the average cost of hospitalization (TOTCHG), and in-hospital mortality. The number of patients who had CABG and a history of COVID-19 (CABGCOVID) was 19,625, while the number of patients who had CABG and no history of COVID-19 (CABGNOCOVID) was168,049. The mean age of CABGCOVID patients was 67.6 years (SE=0.92), while the mean age of CABGNOCOVID patients was 66.3 years (SE=0.76). In CABGCOVID patients, in-hospital mortality was 55 (0.87%) with a 220% increase in the odds of mortality (p < 0.001), while in CABGNOCOVID patients, in-hospital mortality was 4294 (0.25%) with a 69% decrease in the odds of mortality (p < 0.001). The mean LOS for CABGCOVID patients was 18.2 days (SE=1.12) and 9.9 days (SE=0.724) in CABGNOCOVID patients. The TOTCHG were $360,325 (SE=30770) and $261742 (SE=4973) for CABGCOVID and CABGNOCOVID patients, respectively. The analysis of the 2020 NIS database showed a three times increase in the mortality rate of CABGCOVID patients compared to CABGNOCOVID patients. The mean LOS was twice the duration for CABGCOVID patients compared to CABGNOCOVID patients. With regards to TOTCHG, there was a significant difference in the cost of hospitalization in the CABGCOVID group.
