BACKGROUND: Emerging clinical evidence has shown that COVID-19 patients are complicated with venous thromboembolism (VTE), consisting of deep vein thrombosis (DVT) and pulmonary embolism (PE). The prevalence of VTE in hospitalized COVID-19 patients is unclear. METHODS: Eligible studies on COVID-19 were collected from PubMed, Web of Science, and Embase. Patient characteristics and information were extracted for three categories of patients: Consecutive, ICU, and non-ICU group. All PEs and DVTs were diagnosed by computed tomographic pulmonary arteriography and duplex ultrasound, respectively. A subgroup analysis of testing strategies in ICU and non-ICU patients for PE and DVT was also performed. RESULTS: Forty clinical studies involving 7966 hospitalized COVID-19 patients were included. Pooled VTE prevalence was 13% in consecutive patients (95%CI: 0.05–0.24; I(2)=97%), 7% in non-ICU patients (95%CI: 0.01-0.18; I(2)=93%), and 31% in ICU patients (95%CI: 0.22–0.42; I(2)=91%). ICU patients had the highest prevalence of PE among the three groups (17%, 95%CI: 0.12-0.23, vs. 8% in consecutive patients with 95%CI: 0.04-0.13, 4% in non-ICU with 95%CI: 0.01-0.08). ICU patients also had the highest DVT prevalence (25%, 95%CI: 0.14-0.37, vs. 7% in consecutive patients with 95%CI: 0.03-0.14, 7% in non-ICU with 95%CI: 0.02-0.14). The subgroup analysis showed a 3-fold improvement in PE and DVT detections rate in both ICU and non-ICU patients with COVID-19 when screening test for VTE was applied. In the settings of screening tests for VTE, ICU patients have a significantly higher prevalence of PE (37% vs. 10%, p<0.0001) and DVT (40% vs. 12%, p=0.0065) compared to non-ICU patients. CONCLUSIONS: VTE is common in hospitalized COVID-19 patients, especially among ICU patients. Screening tests for PE and DVT may significantly improve detection rates in both ICU and non-ICU patients with COVID-19 than tests based on clinical suspicion.
