ABSTRACT
Aim and

background:

The high mortality associated with the thrombotic events in hospitalised COVID-19 patients resulted in the usage of anticoagulants in varying doses. Whether the high-dose anticoagulants have led to better outcomes or higher incidence of clinically significant bleeding events is still debatable.

Objectives:

To find the incidence of clinically significant bleeding events in moderate to severe COVID-19 patients on therapeutic anticoagulation and the factors influencing these events. Materials and

methods:

In our retrospective, single-centre, cohort study of 155 critically ill COVID-19 patients we observed the incidence of clinically significant bleeding. Multivariate regression models were used to evaluate the association between anticoagulant regimen, coagulation, and inflammatory markers with the incidence of bleeding and thrombotic events.

Results:

The incidence of Clinically Relevant Non-Major Bleeding (CRNMB) was 33.5% (26.17-41.46%,) and major bleeding was 9.03% (5.02-14.69%). The anticoagulation intensity at baseline had a very high odds of major bleeding when Enoxaparin and dual antiplatelet therapy were used together (adjusted OR of 434.09 [3.81-49502.95], p < 0.05). At admission, bleeders had a poorer P/F ratio with more patients on invasive ventilation. At the time of bleeding, the bleeders had a higher d-dimer, ferritin, CRP, and procalcitonin. The subhazard ratio (SHR) for death in bleeders was 3.35 (95% CI, 1.97-5.65;p < 0.001).

Conclusion:

The incidence of bleeding in critically ill COVID-19 patients on therapeutic anticoagulation increases with the severity of the disease as well as with concurrent use of dual antiplatelets. Major bleeding may also contribute to higher mortality.
