Characteristics and outcomes of hospitalized adult COVID-19 patients in Georgia
Abstract
Objective
Describe presenting characteristics of hospitalized patients and explore factors associated with in-hospital mortality during the first wave of pandemic in Georgia.
Methods
This retrospective study included 582 adult patients admitted to 9 dedicated COVID-19 hospitals as of July 30, 2020 (72% of all hospitalizations). Data were abstracted from medical charts. Factors associated with mortality were evaluated in multivariable Poisson regression analysis.
Results
Among 582 adults included in this analysis 14.9% were 65+ years old, 49.1% were women, 59.3% had uni- or bi-lateral lung involvement on chest computed tomography, 27.1% had any co-morbidity, 13.2% patients had lymphopenia, 4.1% had neutophilosis, 4.8% had low platelet count, 37.6% had d-dimer levels of >0.5 mcg/l. Overall mortality was 2.1% (12/582). After excluding mild infections, mortality among patients with moderate-to-critical disease was 3.0% (12/399), while among patients with severe-to-critical disease mortality was 12.7% (8/63). Baseline characteristics associated with increased risk of mortality in multivariate regression analysis included: age ≥65 years (RR: 10.38, 95% CI: 1.30-82.75), presence of any chronic co-morbidity (RR: 20.71, 95% CI: 1.58-270.99), lymphopenia (RR: 4.76, 95% CI: 1.52-14.93), neutrophilosis (RR: 7.22, 95% CI: 1.27-41.12), low platelet count (RR: 6.92, 95% CI: 1.18-40.54), elevated d-dimer (RR: 4.45, 95% CI: 1.48-13.35), elevated AST (RR: 6.33, 95% CI: 1.18-33.98).
Conclusion
In-hospital mortality during the first wave of pandemic in Georgia was low. We identified several risk factors (older age, co-morbidities and laboratory abnormalities) associated with poor outcome that should provide guidance for planning health sector response as pandemic continues to evolve.
