Insights
COVID-19 associated coagulopathy prompted US hospitals to create management protocols. While most agreed on heparin for venous thromboembolism (VTE) prophylaxis, significant differences existed in testing, dosing, and extended prophylaxis strategies.
Area of Science:
- Internal Medicine
- Hematology
- Infectious Diseases
Background:
- The Coronavirus disease 2019 (COVID-19) pandemic presented unique challenges, including the emergence of coagulopathy and thrombotic complications.
- Hospitals rapidly developed institutional protocols to manage COVID-19-related thrombosis and coagulopathy.
Discussion:
- Analysis of 21 protocols from US academic medical centers (January-May 2020) revealed variations in management strategies.
- Greatest consensus was observed for heparin-based pharmacologic venous thromboembolism (VTE) prophylaxis in non-contraindicated COVID-19 patients.
Key Insights:
- Significant protocol discrepancies were noted concerning D-dimer testing, VTE prophylaxis dosing, and post-discharge prophylaxis indications.
- Variations also existed in VTE evaluation methods and the use of empiric therapeutic anticoagulation.
Outlook:
- The observed heterogeneity in COVID-19 coagulopathy management protocols highlights the need for standardized, evidence-based international guidelines.
- Further research is crucial to refine optimal anticoagulation strategies for COVID-19 patients.
Abstract:
As the Coronavirus disease 2019 (COVID-19) pandemic spread to the US, so too did descriptions of an associated coagulopathy and thrombotic complications. Hospitals created institutional protocols for inpatient management of COVID-19 coagulopathy and thrombosis in response to this developing data. We collected and analyzed protocols from 21 US academic medical centers developed between January and May 2020. We found greatest consensus on recommendations for heparin-based pharmacologic venous thromboembolism (VTE) prophylaxis in COVID-19 patients without contraindications. Protocols differed regarding incorporation of D-dimer tests, dosing of VTE prophylaxis, indications for post-discharge pharmacologic VTE prophylaxis, how to evaluate for VTE, and the use of empiric therapeutic anticoagulation. These findings support ongoing efforts to establish international, evidence-based guidelines.
