Outcomes of COVID-19 and Factors Associated With Its Severity Among Hospitalized Patients With and Without Systemic Rheumatic Disease During the First Wave of the Pandemic in New York City.

ABSTRACT

BACKGROUND/OBJECTIVE: Conflicting data exist regarding whether patients with systemic rheumatic disease (SRD) experience more severe outcomes related to COVID-19. Using data from adult patients hospitalized with COVID-19 in New York City during the first wave of the pandemic, we evaluated whether patients with SRD were at an increased risk for severe outcomes. METHODS: We conducted a medical records review study including patients aged ≥18 years with confirmed SARS-CoV-2 infection hospitalized at 3 NewYork-Presbyterian sites, March 3-May 15, 2020. Inverse probability of treatment weighting was applied to a multivariable logistic regression model to assess the association between SRD status and the composite of mechanical ventilation, intensive care unit admission, or death. RESULTS: Of 3710 patients hospitalized with COVID-19 (mean [SD] age, 63.7 [17.0] years; 41% female, 29% White, and 34% Hispanic/Latinx), 92 (2.5%) had SRD. Patients with SRD had similar age and body mass index but were more likely to be female, ever smokers, and White or Black, compared with those without SRD. A higher proportion of patients with versus without SRD had hypertension and pulmonary disease, and used hydroxychloroquine, corticosteroids, and immunomodulatory/immunosuppressive medications before admission. In the weighted multivariable analysis, patients with SRD had an odds ratio of 1.24 (95% confidence interval, 1.10-1.41; p < 0.01) for the composite of mechanical ventilation, intensive care unit admission, or death, compared with patients without SRD. CONCLUSIONS: During the initial peak of the pandemic in New York City, patients with versus without SRD hospitalized with COVID-19 had a 24% increased likelihood of having severe COVID-19 after multivariable adjustment.
