Abstract
BackgroundFever and cough are frequently reported in COVID-19 infections, although little is known about the subgroup of symptomatic patients who do not manifest these classic symptoms. We aimed to compare clinical manifestations and outcomes for hospitalized COVID-19 patients with typical vs. atypical presentations and identify risk factors for atypical COVID-19 presentations.MethodsWe conducted a retrospective cohort of all patients hospitalized with laboratory-confirmed COVID-19 infections during 3/13- 5/13/2020 at UW Health, a network of 3 acute-care hospitals in Midwest. We defined atypical cases as patients hospitalized for COVID-19 related reasons presenting without fever and cough and compared them in univariate analysis with patients manifesting both symptoms (controls). We identified independent risk factors for atypical COVID-19 presentations by logistic regression.ResultsAmong the 163 patients hospitalized during the 60-day study frame, 39 (24%) had atypical presentations. Table 1 shows demographic, clinical manifestations, and outcomes of atypical vs. typical cases. On univariate analysis, atypical cases were more likely to be older, reside in a long-term-care facility (LTCF), have underlying diabetes mellitus, stroke, cardiac disease, and deny myalgias or dyspnea, despite having no significant difference in the prevalence of hypoxia or radiological lung infiltrates. Atypical cases also had a significantly higher Beta-Natriuretic-Peptide and lower C-Reactive-Protein, although other inflammatory markers were not significantly different. They were less likely to be admitted to the ICU, and more likely to die within 30 days, as older patients with respiratory failure and multiple comorbidities opted for comfort measures and less aggressive care. On multivariate analysis, LTCF residence was the only independent predictor for atypical status (Table 2). ConclusionLTCF residents are more likely to experience COVID-19 respiratory illness (hypoxia, pneumonia) without classic symptoms (fever, cough, myalgias, dyspnea). Given the excessive pandemic burden in the LTCF setting, timely recognition and diagnosis of these atypical, more subtle presentations is critical.Disclosures All Authors: No reported disclosures
