Abstract

Background: Few studies reported the risk factors of fatal outcome of hospitalized patients with coronavirus disease 2019 (COVID-19). We aimed to identify the independent risk factors associated with fatal outcome of hospitalized COVID-19 patients.

Methods: The clinical data of 109 consecutive COVID-19 patients including 40 (36.7%) common cases and 69 (63.3%) severe cases were included and analyzed.

Results: Multivariate regression analysis indicated that platelets (PLT, OR, 0.988; 95% CI, 0.978-0.998; P=0.017) and C-reactive protein (CRP) (OR, 1.047; 95% CI, 1.026-1.068; P<0.001) levels were the independent risk factors of fatal outcome in COVID-19 patients. The optimal cut-off value of PLT counts for predicting fatal outcome was 161x109/L with the area under receiver operating characteristic curve (AUROC) of 0.824 (95% CI, 0.739-0.890). The optimal cut-off value of CRP for the prediction of fatal outcome was 46.2 mg/L with the AUROC of 0.954 (95% CI, 0.896-0.985). The CRP levels had higher predictive values for fatal outcome than PLT (P=0.016). The cumulative survival rate was significantly higher in patients with PLT>161x109/L compared with patients with PLT≤161x109/L (89.4% vs. 12.5%, log-rank test X2=72.17; P<0.001). Survival rate of COVID-19 patients was prominently higher in CRP≤46.2 mg/L patients compared with patients with CRP>46.2 mg/L (95.9% vs. 22.9%, log-rank test X2=77.85; P<0.001).

Conclusions: PLT counts and CRP levels could predict fatal outcome of hospitalized COVID-19 patients with relatively high accuracy.

COVID-19住院患者死亡结局的危险因素

背景:影响2019冠状病毒病(COVID-19)住院患者死亡结局的危险因素报道较少。我们的目的是确定与住院COVID-19患者致命结局相关的独立危险因素。方法:对109例新冠肺炎患者的临床资料进行分析，其中普通病例40例(36.7%)，重症病例69例(63.3%)。结果:多因素回归分析显示血小板(PLT, OR, 0.988;95% ci, 0.978-0.998;P=0.017)和c反应蛋白(CRP) (OR, 1.047;95% ci, 1.026-1.068;P161x109/L与PLT≤161x109/L患者比较(89.4% vs. 12.5%， log-rank检验X2=72.17;P46.2 mg/L (95.9% vs. 22.9%， log-rank检验X2=77.85;结论:PLT计数和CRP水平可预测COVID-19住院患者的致命结局，准确率较高。

期刊介绍： Discovery Medicine publishes novel, provocative ideas and research findings that challenge conventional notions about disease mechanisms, diagnosis, treatment, or any of the life sciences subjects. It publishes cutting-edge, reliable, and authoritative information in all branches of life sciences but primarily in the following areas: Novel therapies and diagnostics (approved or experimental); innovative ideas, research technologies, and translational research that will give rise to the next generation of new drugs and therapies; breakthrough understanding of mechanism of disease, biology, and physiology; and commercialization of biomedical discoveries pertaining to the development of new drugs, therapies, medical devices, and research technology.
