[Diagnosis of DIC based on evidence]

Area of Science:

• Hematology
• Pathophysiology
• Clinical Diagnostics

Context:

• Disseminated intravascular coagulation (DIC) diagnosis has evolved from microthrombi detection to complex laboratory assessments.
• Existing diagnostic criteria, including those from the International Society of Thrombosis Haemostasis (ISTH) and Japanese Association for Acute Medicine (JAAM), utilize scoring systems based on global coagulation tests.
• Comparative analysis using ROC curves indicates similar diagnostic performance but differing sensitivity and specificity profiles among the current criteria.

Purpose:

• To evaluate the diagnostic efficacy of existing criteria for disseminated intravascular coagulation (DIC).
• To explore the potential of molecular hemostatic markers for enhancing DIC diagnostic accuracy.
• To advocate for the development and validation of new, simplified DIC diagnostic criteria.

Summary:

• The diagnosis of DIC relies on laboratory tests assessing hemostatic abnormalities, with established criteria from ISTH, JAAM, and Japanese Ministry Health and Welfare showing comparable diagnostic abilities but varying sensitivity and specificity.
• Molecular markers like thrombin antithrombin complex and D-dimer show promise for improving diagnostic precision.
• Further research, including prospective studies in infectious diseases utilizing molecular markers, is recommended to refine and simplify DIC diagnosis.

Impact:

• Highlights the need for improved diagnostic strategies for DIC.
• Suggests specific molecular markers as key components for future diagnostic criteria.
• Emphasizes the importance of prospective studies for validating new diagnostic approaches in relevant clinical settings.
