INTRODUCTION: COVID-19 induces a prothrombotic state as evidenced by microvascular thrombi in the renal and pulmonary vasculature . However, limited data are available to guide the antithrombotic prophylaxis strategy
OBJECTIVES: We sought to determine if empiric therapeutic anticoagulation (tAC) affected survival in COVID-19 patients compared to prophylactic anticoagulation (pAC).
METHODS and MATERIALS: A retrospective cohort study was done to determine the impact of therapeutic AC in COVID-19 hospitalized patients between August 25-2020 and October 15-2020. Independent T_test was performed to calculate mean differences, and odds ratios were calculated to examine the relationship between AC dosing and clinical outcomes.
RESULTS: Among 106 patients 39 were treated with therapeutic AC and 67 were treated with prophylactic AC. When comparing clinical outcomes between the two arms ; there was no statistically significant difference in in-hospital mortality (OR:1.23, 95%CI:0.5-3.1, P:0.6). As well as the upgrade to ICU/Intubation (OR:0.98, 95%CI:0.3-2.4, P:0.9), also the need to NIV (Non-invasive mechanical ventilation) was not statistically different (OR:1.06 ,95%CI:0.4-2.6, P:0.8).
While major bleeding was significantly higher in the therapeutic group [ (7.7%) versus (1.5%)] (OR:0.18 ,95%CI:0.01 -1.8, P:0.01). Thrombotic events occurred in 5 patients (4.7%), and was significantly higher in the prophylactic group [(6%) versus (2.6%)] (OR:2.4 ,95%CI:1.2-12.3, P:0.04).
CONCLUSION: Therapeutic AC compared to prophylactic AC did not result in a significant difference in the primary outcomes of in-hospital mortality, upgrade to ICU/Intubation , need to NIV. Our results do not support the empirical use of therapeutic dose in unselected patients. More studies are required to determine the optimal AC regimens.
