364 - Baseline characteristics, comorbidities, and outcomes of COVID-19 patients hospitalized in Southwest Georgia, U.S. – an interim analysis of an early hot spot

Background: Understanding the spectrum of disease severity and death are critical for identifying unrecognized risk factors associated with morbidity and mortality from coronavirus disease 19 (COVID-19).  The purpose of this study was to describe the baseline characteristics, clinical presentation, and outcomes among patients hospitalized with COVID-19 in a major hotspot in the U.S. Southeast.

Methods: This multicenter retrospective chart review included adult patients hospitalized with COVID-19, defined by laboratory-detected severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, in Southwest Georgia.  The primary outcome was mortality, which was assessed through discharge or June 14, 2020, whichever occurred first.  Secondary outcomes included comorbidities, laboratory and radiographic findings, as well as clinical course. 

Results: A total of 120 patients were included with a median age of 61 years (IQR 50-72). The majority were African American (73%) and female (56%). Comorbidities on admission were present in 88% of patients; most prevalent were hypertension (76%), diabetes mellitus (55%), and chronic pulmonary disease (27%).  Median Charlson comorbidity index was 4 (IQR 2-6) and BMI was 32.8 kg/m² (IQR 26.2-39.5).  On presentation, patients most often complained of dyspnea (69%), fever (63%), and cough (53%), with a median SOFA score of 2 (IQR 2-4).  Most patients were admitted to the general ward (71%), of which 17% were subsequently transferred to ICU.  During hospitalization, 27% were mechanically ventilated for a median 11 days (IQR 5-13.5), 18% developed ARDS, and 43% developed AKI. Median length of stay was 9.5 days (IQR 3.75-14).  Overall mortality was 20%, which was significantly higher among patients with comorbidities (p = 0.047), as well as those who developed ARDS (p < 0.001) or AKI (p = 0.027).

Conclusion: Most reports of COVID-19 have focused on large urban settings.  However, early during the pandemic, we identified a large cluster of cases with a high-case fatality rate in a semirural setting in Southwest Georgia in the U.S.
