Insights
Thromboelastography effectively identifies hypercoagulability in COVID-19 patients and predicts thrombotic risks. This whole blood test offers advantages over traditional lab tests for managing COVID-19-associated coagulopathy.
Area of Science:
- Hematology
- Critical Care Medicine
- Diagnostic Technologies
Background:
- COVID-19-associated coagulopathy (CAC) presents a hypercoagulable state with increased thrombotic risk.
- Standard diagnostic and management protocols for CAC are not yet established.
- Whole blood viscoelastic tests offer a comprehensive assessment of coagulation status.
Purpose of the Study:
- To systematically review the utility of thromboelastography (TEG) in managing patients with COVID-19.
- To evaluate TEG's ability to identify hypercoagulable states and predict thrombotic complications in COVID-19 patients.
Main Methods:
- Systematic literature review of MEDLINE (PubMed) and Cochrane databases.
- Extraction and analysis of TEG parameter measurements and clinical outcomes from 15 publications.
- Comparison of TEG benefits against traditional laboratory coagulation tests.
Main Results:
- Thromboelastography can identify and assess hypercoagulability in COVID-19 patients.
- TEG utilization in this population predicts thrombotic complications.
- TEG offers advantages over standard laboratory coagulation tests for CAC diagnosis.
Conclusions:
- Thromboelastography is a valuable tool for optimizing the diagnosis of COVID-19-associated coagulopathy.
- TEG can improve patient management strategies for COVID-19.
- Further research will elucidate optimal TEG applications in COVID-19 patient care.
Abstract:
Coronavirus disease 2019 (COVID-19)-associated coagulopathy (CAC), characterized by hypercoagulability and an increased risk of thrombotic complications, is an important consideration in the management of patients with COVID-19. As COVID-19 is a new disease, no standard of care for the diagnosis or management of its associated coagulopathy is yet established. Whole blood viscoelastic tests, such as thromboelastography (TEG® hemostasis analyzer), analyze whole blood to provide a complete overview of the coagulation status. We conducted a systematic review of thromboelastography for management of patients with COVID-19, using MEDLINE (PubMed) and Cochrane databases. TEG® parameter measurements and clinical outcomes data were extracted for analysis. Our review found 15 publications, with overall results showing thromboelastography can identify and assess a hypercoagulable state in patients with COVID-19. Furthermore, utilization of thromboelastography in this patient population was shown to predict thrombotic complications. The benefits of thromboelastography presented here, in addition to advantages compared with laboratory coagulation tests, position thromboelastography as an important opportunity for optimizing diagnosis of CAC and improving patient management in COVID-19. Given that the benefits of thromboelastography have already been demonstrated in several other clinical applications, we anticipate that clinical data from future studies in patients with COVID-19 will further elucidate the optimal use of thromboelastography in this patient population.
