We included patients under anticoagulant therapy in the clinical course. The patients were allocated to 3 groups: Group A - low-dose (prophylactic) low-molecular-weight-heparin (LMWH) therapy, Group B - high-dose (therapeutic) LMWH therapy, and patients that received aspirin additional to the high-dose (therapeutic) LMWH as Group C. Primary outcomes were overall mortality rates and length of stay (LOS) in ICU. Secondary outcomes were rates of major hemorrhagic and thrombotic events.Results: Records of 475 patients were reviewed and 164 patients were included. No significant difference was detected in mortality rates between groups (p=0.135). Intensive care unit stay was 13 (9-24.5) days in Group A, 11 (8.75-23) days in Group B, and 13 (9-17) days in Group C without a significant difference (p=0.547). No significant difference was detected between groups in terms of thrombotic (p=0.565) and hemorrhagic events (p=0.615).Conclusion: A high-dose anticoagulation therapy and addition of aspirin to LMWH therapy did not decrease the mortality rates and LOS in ICU in critical ill COVİD-19 patients. In addition, it did not increase the incidence of major hemorrhage and major thrombotic events. ER -
