# metadata.dc.description.abstract[].value
Background: Venous thromboembolic events have been one of the main causes of mortality among hospitalized patients with coronavirus disease 2019 (COVID-19) pneumonia. The aim of our study was to describe the prevalence of deep vein thrombosis (DVT) in noncritically ill patients with COVID-19 pneumonia and correlate such observations with the thromboprophylaxis received. Methods: We performed a prospective cohort study of 67 patients admitted to the hospital for COVID-19 pneumonia. The diagnosis was confirmed using polymerase chain reaction testing of nasopharyngeal specimens. The deep veins were examined using compression duplex ultrasonography with the transducer on B-mode. The patients were separated into two groups for statistical analysis: those receiving low-molecular-weight heparin prophylaxis and those receiving intermediate or complete anticoagulation treatment. Risk analysis and logistic regression were performed. Results: Of the 67 patients, 57 were included in the present study after applying the inclusion and exclusion criteria; 49.1% were women, and the patient mean age was 71.3 years. All 57 patients had undergone compression duplex ultrasonography. Of these 57 patients, 6 were diagnosed with DVT, for an in-hospital rate of DVT in patients with COVID-19 pneumonia of 10.5%. All the patients who had presented with DVT had been receiving low-molecular-weight heparin prophylaxis. The patients receiving prophylactic anticoagulation treatment had a greater risk of DVT (16.21%; 95% confidence interval, 0.04-0.28; P = .056) compared with those receiving intermediate or complete anticoagulation treatment. We also found a protective factor for DVT in the intermediate or complete anticoagulation treatment group (odds ratio, 0.19; 95% confidence interval, 0.08-0.46; P < .05). Conclusions: Noncritically ill, hospitalized patients with COVID-19 pneumonia have a high risk of DVT despite receipt of correct, standard thromboprophylaxis.
