ISTH

What ISTH does

ISTH is a nonprofit professional society, incorporated in North Carolina (USA) and headquartered in Carrboro, that serves the global thrombosis and hemostasis clinical and research community. The society's core offerings are organized around three pillars: two peer-reviewed journals (the Journal of Thrombosis and Haemostasis, JTH, and Research and Practice in Thrombosis and Haemostasis, RPTH); an annual international congress drawing attendees from 100+ countries; and a Scientific and Standardization Committee (SSC) comprising 21 subcommittees that develop nomenclature, standards, and reference materials — including the Secondary Coagulation Standard Plasma calibrated against WHO International Standards.

The platform architecture spans the ISTH Academy (e-learning with webinars, courses, CME), My ISTH Community (member portal), REDCap-based clinical registries, and CoagBase (a coagulation and platelet protein/gene reference database with HGVS conversion tooling). Supporting programs include World Thrombosis Day (global awareness campaign observed October 13), the Reach-the-World fellowship program for developing countries, clinical practice guidelines, the SSC on the Case virtual learning series, and a Gene Therapy in Hemophilia portal.

Revenue is generated through a diversified nonprofit model: tiered membership dues (Premier $180/year to free student), congress registration, journal licensing, educational program fees, content licensing to pharmaceutical/medical device companies and CME providers, industry sponsorships (including an Industry Roundtable with partners such as Roche, Pfizer, Novo Nordisk, Novartis, BMS, J&J, Sobi, Regeneron, STAR Therapeutics), and donations. With 7,700+ members in 110+ countries and a ~30-person staff, the organization operates as a member-driven, governance-led society.

Direct peers

• International Society of Hematology (ISH): ISH is a global hematology professional society focused on education and international collaboration across all hematology subspecialties. Comparable in mission and member-based structure, though broader in scope than ISTH.
• European Hematology Association (EHA): EHA is the principal European hematology society, publishing HemaSphere and running the annual EHA Congress. It overlaps with ISTH on European hematology professionals, joint educational programming, and clinical guideline development.
• World Federation of Hemophilia (WFH): WFH is a global non-profit focused specifically on hemophilia and other inherited bleeding disorders, serving national member organizations in 100+ countries. Highly comparable to ISTH's bleeding-disorder standardization, congress, and global training activities.

Broad incumbents

• European Society of Cardiology (ESC): ESC represents European cardiology and produces guidelines that intersect with ISTH's atrial fibrillation, anticoagulation, and venous thromboembolism guidance. Comparable as a specialty society publisher of journals and guidelines with industry-supported congresses.
• American Heart Association (AHA): AHA is a major cardiovascular professional society and publisher of Circulation and Stroke journals, with significant overlap on arterial thrombosis, stroke, and anticoagulation guidelines. Comparable in journals, congresses, and pharma-funded education, but broader in scope.
• American Society of Hematology (ASH): ASH is the largest hematology professional society in the world, with ~18,000 members, publishing Blood journal and hosting a major annual meeting. ISTH sits adjacent as a thrombosis/hemostasis-focused sub-specialty society, with overlapping clinical and research audiences.

Emerging players

• Society for Vascular Medicine: SVM is a smaller US-based society focused on vascular medicine with meaningful overlap on venous thromboembolism and anticoagulation topics. Comparable in member-based non-profit structure and clinical guideline activity but smaller scale.
• Anticoagulation Forum: The Anticoagulation Forum is a US non-profit multidisciplinary organization dedicated to improving anticoagulation care. It overlaps with ISTH on antithrombotic therapy education, clinical guidance, and industry-supported programming, but with a narrower clinical focus.

Others

• International Society on Thrombosis and Haemostasis - direct society peers via related societies network: ISTH maintains a global network of related national thrombosis and hemostasis societies (e.g., Italian, German, Japanese societies) that compete for local membership but collaborate on international standards and meetings. These are the closest functional equivalents in their respective geographies.

Regional players

• British Society for Haematology (BSH): BSH is the UK's national hematology society, publishing the British Journal of Haematology and running an annual scientific meeting. Comparable in mission but primarily serves UK clinicians and overlaps with ISTH on guideline development.
