Insights Regarding Outcomes for Covid-19 Hospitalizations with Adult Congenital Heart Disease (Achd)

ABSTRACT

Background: As of December 2022, SARS-CoV-2 coronavirus resulted in over 6 million deaths worldwide.[1] It was realized early into the pandemic, that COVID-19 significantly impacts the Cardiovascular system. [2] Patients with pre-existing cardiovascular comorbidities were particularly at higher risk of adverse outcomes during their hospitalizations. [3] Similarly, it can be safe to assume patients with adult congenital heart disease (ACHD) should considered a high-risk population for the development of severe COVID infection with increased rates of significant cardiovascular complications. Objective(s) Based on this reasoning and the paucity of data available on this topic using a large database, we sought to investigate the outcomes of patients with ACHD who were admitted to the hospital with COVID-19. Method(s) The National Inpatient Sample database for 2020 was queried to identify adult hospitalizations with a primary diagnosis of COVID-19 and a secondary diagnosis of ACHD using International Classification of Diseases - 10 Clinical Modification (ICD-10-CM) codes. The primary outcome studied was inpatient mortality, while secondary outcomes included inpatient complications, mean length of stay (LOS), and total hospital charge (THC). Multivariate logistic and linear regression analyses were used to adjust for possible confounders and analyze the variables. Result(s) Out of 1,050,045 COVID-19 hospitalizations registered, 2,425 (0.23%) had ACHD as a secondary diagnosis. Encounters with ACHD who were hospitalized with COVID-19 had significantly higher adjusted odds of inpatient mortality (Adjusted Odds Ratio [aOR] 1.4, [95% CI 1.05-1.88], p=0.022), Longer LOS (Mean 2.4 days, [95% CI 1.35-3.40], p <0.001), and higher Total Hospital Charges (Mean $53,000, [95% CI 20811-85190], p <0.001). A Forrest plot (Figure 1) demonstrates a graphical representation of the multivariate analysis of the significant in-hospital complications when adjusted for patient demographics, comorbidities, and hospital characteristics. Conclusion(s) Among COVID-19 hospitalizations, those with a history of congenital heart diseases had significantly worse outcomes in terms of in-hospital mortality, sepsis;the need for endotracheal intubation, mechanical ventilation, and vasopressors;developing acute kidney injury and pulmonary embolism, in addition to the longer length of stay, and higher total hospital charges.
