This study evaluates an integrated healthcare model for venous thromboembolism (VTE) patients. The research aims to improve care delivery and patient outcomes through multidisciplinary services and a patient registry.
Area of Science:
- Hematology
- Public Health
- Health Services Research
Background:
- Venous thromboembolism (VTE) presents significant morbidity and mortality, with care delivery often incomplete and variable.
- Existing comprehensive healthcare models for chronic disorders like hemophilia have not been fully evaluated for coagulation disorders.
- The Centers for Disease Control and Prevention (CDC) is addressing this gap by collaborating with Thrombosis and Hemostasis Centers.
Purpose of the Study:
- To determine the efficacy of integrated, multidisciplinary care and prevention services for hemostatic disorders.
- To assess unmet needs in service delivery and identify strategies to improve access to care.
- To develop effective disease management messages and foster provider training programs.
Main Methods:
- A collaboration between the CDC and eight Thrombosis and Hemostasis Centers.
- Implementation of a web-based patient registry for prospective tracking of service allocation and patient outcomes.
- Enrollment of over 2,600 patients and collection of data on more than 5,000 visits between August 2003 and March 2006.
Main Results:
- Characterization of patients receiving care and documentation of health services provided.
- Establishment of a network for data collection across multiple centers.
- Foundation laid for future collaborative clinical and epidemiologic investigations.
Conclusions:
- Integrated multidisciplinary care models show promise for improving management of thrombosis and thrombophilia.
- The established patient registry and data network are crucial for evaluating clinical outcomes and enhancing expertise.
- Further research and enhanced provider skills are essential for optimizing patient care in hemostatic disorders.

Introduction to Hemostasis
The three phases of hemostasis involve many clotting factors present in plasma and several substances released by platelets and injured tissue cells. It is a fast, localized, and...
Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which forms a...
