The characteristics of laboratory tests at admission and the risk factors for adverse clinical outcomes of severe and critical COVID-19 patients
Abstract Background Coronavirus disease 2019(COVID-19) is a worldwide pandemic.In this study, we aimed to evaluate the risk factors of death from severe and critical COVID-19 patients.Method A retrospective study of patients diagnosed with severe and critical COVID-19 from four hospitals in Wuhan, China, describing the clinical characteristics and laboratory results, and using Cox regression to study the risk factors was conducted.Results Four hundred and forty-six patients with COVID-19 showed a high case fatality rate(CFR)(20.2%). All patients required oxygen therapy, and 52(12%) patients required invasive mechanical ventilation,of which 50(96%) patients died.The univariate Cox proportional hazard model showed a white blood cell count of more than 10 × 10⁹/L(HR3.903,95%CI 2.413 to 6.313),patients’ risk of death significantly increased.The multivariate Cox proportional hazard model demonstrated that older age (HR 1.074, 95% CI 1.050 to 1.098) was an independent risk factor and high white blood cell count(HR 1.119, 95% CI 1.056 to 1.186)was a predictive factor for COVID-19 on admission.Conclusions COVID-19 is a new disease entity that carries significant risk of morbidity and CFR.Older age was an independent risk factor and high white blood cell was a predictive factor for COVID-19..
