Popis: Background Thrombotic events can increase the COVID-19 associated disease mortality. The administration of prophylactic anticoagulants had been shown to decrease the incidence of thrombosis, mortality, and ICU admission rates in COVID-19 patients. Aims The present study investigates the rate of thrombosis with early anticoagulation prophylaxis, the various risk factors for thrombotic events, and the overall survival rate in hospitalized COVID-19 cases. Methods In this prospective observational study, 425 patients aged ≥14 years were included in the study who were hospitalized with COVID-19 related symptoms from March to October 2020 at two tertiary care hospitals in the Kingdom of Saudi Arabia. Venous thromboembolism (VTE) score was evaluated, and VTE prophylaxis was administered according to the hospital guidelines. Patients’ demographics, comorbidities, disease presentation, and sequential hematological profiles were also recorded. Samples were collected at different time points to determine the hematological profiles. Results Out of 425 with positive COVID-19 subjects, eight (1.9%) patients developed thrombosis during admission, with pulmonary embolism being the most common type. VTE prophylaxis was administered to 394 (92.7%) patients. These anticoagulants included enoxaparin (86.3%), heparin (12.7%), warfarin (0.8%) and apixaban (0.3%). Comorbid conditions were recorded in 253 (59.5%) patients. ICU admission rate was 28% (n = 119), with a median time to transfer to ICU of 1 day (r: 0-33 days). A trend of high VTE score (5.0) with ICU admission and mortality ( P =
