ABSTRACT
To systematically analyze the blood coagulation features of coronavirus disease 2019 (COVID-19) patients to provide a reference for clinical practice. An electronic search in PubMed, EMbase, Web of Science, Scopus, CNKI, WanFang Data, and VIP databases to identify studies describing the blood coagulation features of COVID-19 patients from 1 January 2020 to 21 April 2020. Three reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies, then, the meta-analysis was performed by using Stata 12.0 software. Thirty-four studies involving 6492 COVID-19 patients were included. Meta-analysis showed that patients with severe disease showed significantly lower platelet count (weighted mean differences [WMD] -16.29 × 109 /L; 95% confidence interval [CI] -25.34 to -7.23) and shorter activated partial thromboplastin time (WMD -0.81 seconds; 95% CI -1.94 to 0.33) but higher D-dimer levels (WMD 0.44 µg/mL; 95% CI 0.29-0.58), higher fibrinogen levels (WMD 0.51 g/L; 95% CI 0.33-0.69) and longer prothrombin time (PT; WMD 0.65 seconds; 95% CI 0.44-0.86). Patients who died showed significantly higher D-dimer levels (WMD 6.58 µg/mL; 95% CI 3.59-9.57), longer PT (WMD 1.27 seconds; 95% CI 0.49-2.06) and lower platelet count (WMD -39.73 × 109 /L; 95% CI -61.99 to -17.45) than patients who survived. Coagulation dysfunction is common in severe COVID-19 patients and it is associated with severity of COVID-19.
