About

This is a multicenter, prospective, longitudinal, observational cohort study to investigate thrombosis and hemostasis diseases in Chinese patients. This study will collect basic information, diagnostic and treatment information, as well as medical expense information of patients from medical records.The incidence and risk factors of thrombosis and hemostasis diseases, the treatment methods, prognosis and medical expenses of these patients in China will be analyzed. The study will use questionnaire to measure the exposure of patients, and prospectively follow-up to collect the prognosis information.

Full description

Thrombosis and hemostasis diseases are a group of high-risk hematological diseases, characterized by bleeding or hypercoagulability caused by congenital or acquired abnormalities in hemostasis, coagulation, and fibrinolysis. Thrombosis and hemostasis diseases included various bleeding and thrombotic diseases such as primary immune thrombocytopenia (ITP), thrombotic thrombocytopenic purpura (TTP), hemophilia, disseminated intravascular coagulation (DIC), thrombophilia, pregnancy with ITP, pregnancy with prethrombotic state (such as protein C, protein S deficiency, etc.), deep vein thrombosis, pulmonary embolism, thrombocytopenia and coagulation abnormalities after hematopoietic stem cell transplantation, and so on. Thrombosis and hemostasis diseases have a high incidence rate, may affect patients' quality of life and even are associated with the poor survival. However, current studies are mostly based on data from limited sample size cohorts, lacking comprehensive and large-scale prospective cohort studies.
