Outcomes among patients admitted with cardiogenic shock during the first year of the covid-19 pandemic in the united states

ABSTRACT

BackgroundOutcomes of patients hospitalized for cardiogenic shock during the midst of the COVID-19 pandemic in the United States have yet to be well described. This study aimed to examine if the COVID-19 pandemic led to gender differences in in-hospital outcomes, length of stay, and total hospital charges.MethodsData was extracted from the National Inpatient Sample database for the calendar year 2020. Patients who were admitted with a principal diagnosis of cardiogenic shock (R57.0) were identified using relevant International Classification of Disease, and Clinical Modification codes. The key outcomes of mortality, use of mechanical ventilation, use of mechanical circulatory support, hemodialysis, vasopressors use, length of stay, and total hospital charges were then accessed.ResultsThere were 2,670 hospitalizations for a principal diagnosis of cardiogenic shock in 2020, of which 955 were females. After adjusting for age, race, hospital bed size, hospital location, hospital teaching status, insurance status, income level, and Elixhauser comorbidities;we found that females admitted with cardiogenic shock were more likely to require mechanical ventilation (aOR 1.54, 95% CI 1.02- 2.34), but had no difference in mortality, vasopressor use, mechanical circulatory support use, hemodialysis initiation, length of hospital stay and total hospital charges relative males.ConclusionOur study found that females admitted for cardiogenic shock during the first year of the pandemic had significantly higher rates of mechanical ventilation but no difference in other outcomes. Further studies are needed to investigate the effect of COVID-19 on the outcomes of female patients admitted for cardiogenic shock.Conflict of InterestNone
