The Thrombosis Program is committed to improving the lives of children who have developed or are at risk of developing a blood clot.
Part of the Division of Haematology/Oncology, the Thrombosis Program is at the forefront of care for children with blood clots, providing state-of-the-art clinical care and conducting innovative research since 1991.
Did you know? Facts about the Thrombosis Program
- Most of the paediatric doses of the anticoagulants currently used to treat blood clots in children were estimated by the Thrombosis Program at SickKids.
- The team in the Thrombosis Program at SickKids conducted and published the two largest studies on limb blood clots in children.
- Two of the three existing tools for diagnosing long-term complications of blood clots in children were developed by the team in the Thrombosis Program at SickKids.
What we do
The Thrombosis Program’s clinical team consists of a thrombosis nurse practitioner, who is in charge of the Outpatient Paediatric Anticoagulant Clinic, and five staff physicians devoted to providing care to children with blood clots or at increased risk of developing a clot.
Our research team includes our staff physicians, nurses, research coordinators and research fellows dedicated to the design and delivery of clinical research studies in paediatric thrombosis.
Our Thrombosis Research and Clinical Support (TRaCS) program consists of a team of undergraduate and graduate student volunteers who support the dynamic day-to-day interactions both of our clinical and research initiatives.
Our team has operated an internationally renowned training program on paediatric thrombosis since 2001. Visit the Haematology/Oncology to learn more about the Thrombosis/Haemostasis Subspecialty Fellowship.
Who we are
For patients and families
Blood clots help to stop wounds from bleeding, but when they happen in the deep veins of the body they can be harmful. Visit AboutKidsHealth to learn about the signs and causes of blood clots; the complications of blood clots; and the different medical and non-medical treatments that are available for children.

Volunteer with the Thrombosis Research and Clinical Support Program (TRaCS)
We are looking to recruit dedicated, reliable, and talented, college or university students to join our TRaCS volunteer team. Our volunteers are involved in a variety of research and clinical initiatives taking place in-person at our clinic. This includes working closely with physicians, nurses, patients, and their families in both the outpatient and inpatient clinical settings. Volunteers are expected to have good communication skills and the ability to work well both independently and within a team setting. Volunteers will have the opportunity to learn about our ongoing research projects, and be involved with patient recruitment, data collection, and database maintenance, alongside many new skills.
- Availability on Mondays and/or Wednesdays (preferably)
- Commitment to a minimum of 1 shift (approximately 4 hours) per week for a period of six months
- We accept incoming volunteers all year-round
