Disseminated intravascular coagulation is associated with poor prognosis in patients with COVID-19

Area of Science:

• Critical Care Medicine
• Infectious Diseases
• Hematology

Background:

• Coronavirus disease 2019 (COVID-19) is associated with a high risk of thrombotic complications.
• Disseminated intravascular coagulation (DIC) is a serious condition characterized by widespread clotting and bleeding.

Purpose of the Study:

• To determine the incidence and clinical significance of DIC in COVID-19 patients.
• To evaluate the association between DIC and patient outcomes, including multiple organ dysfunction syndrome (MODS) and in-hospital death.

Main Methods:

• A multicenter cohort study utilizing large-scale COVID-19 registry data.
• Patients were classified into DIC and non-DIC groups based on diagnosis on admission and at various time points up to day 15.
• Statistical analysis was performed to assess the predictive performance and independent association of DIC with adverse outcomes.

Main Results:

• The incidence of DIC in COVID-19 patients was 1.1% on admission, rising to 10.9% by day 15.
• DIC diagnosis on admission moderately predicted MODS and in-hospital death.
• Late-onset DIC (diagnosed on days 8 or 15) was significantly associated with lower survival probability and increased in-hospital death.

Conclusions:

• Despite a low initial incidence, DIC is a critical factor in the poor prognosis of COVID-19 patients.
• Early and especially late-onset DIC diagnosis is crucial for identifying high-risk individuals.
• Understanding the role of DIC in COVID-19 pathogenesis is vital for improving patient management and outcomes.
