ISTH

ISTH, or the International Society on Thrombosis and Haemostasis, is a global professional organization dedicated to advancing knowledge and practice related to thrombosis and haemostasis. Its members include clinicians, researchers, and allied health professionals who study or treat disorders of blood clotting and bleeding. The organization aims to improve patient care by promoting high-quality research, education, and clinical guidelines.

Its activities include organizing the annual ISTH Congress, which brings together scientists and clinicians to exchange findings and develop recommendations; publishing scholarly work such as the Journal of Thrombosis and Haemostasis; and developing consensus statements and clinical practice guidelines used by practitioners around the world. The ISTH Academy provides online courses, webinars, and educational resources for students, trainees, and practicing professionals.

ISTH operates through a network of members, national societies, and topic-specific committees. It supports initiatives across specialties including venous thromboembolism, arterial thrombosis, platelet biology, bleeding disorders, pediatric haemostasis, cancer-associated thrombosis, and laboratory methods. The society emphasizes open science, data sharing, and standardization of laboratory assays and clinical terminology.

The ISTH's work influences clinical guidelines and practice worldwide and serves as a resource for researchers, clinicians, and policymakers. Its journals and educational programs contribute to ongoing professional development and to the translation of laboratory research into patient care.

Originating in the late 1960s to provide an international forum for professionals in thrombosis and haemostasis, the ISTH has grown into a global network of individuals and national societies committed to advancing the field through research, education, and collaboration.
