Study aims to predict the risk of blood clots after traumatic injury
Orthopaedic trauma surgeon is one of 20 UCalgary researchers to receive support through Canadian Institute of Health Research Project Grants
A love of sports inspired Dr. Prism Schneider, MD, PhD, to study kinesiology at McGill University. But it was during her time as a summer student in the gait lab at the University of Calgary that she truly discovered her passion.
“We were conducting clinical trials with injured patients, and I thought, ‘Wouldn’t it be amazing to be the surgeon performing the surgical intervention for these patients, and studying them before and after?’ And then somehow I ended up in medical school!” says Schneider, a clinical associate professor in the departments of Surgery and Community Health Sciences at the Cumming School of Medicine (CSM).
Today, as both a clinician and a researcher in the McCaig Institute for Bone and Joint Health and the O’Brien Institute for Public Health at the CSM, Schneider spends half her time performing surgery and treating orthopaedic trauma patients, and the other half doing research on how inflammation affects fracture healing and an individual’s risk of developing venous thromboembolism (blood clots) or excessive bleeding after a traumatic injury. Schneider has received CIHR Project Grant funding for a study to predict the risk of developing blood clots after trauma.
Orthopaedic trauma and blood clots
Patients who suffer a major broken bone, such as a broken femur (thigh bone), have an increased risk for developing blood clots in their legs and life-threatening blood clots in their lungs. These patients receive medication to help prevent blood clots. However, it is expensive and can increase bleeding. In order to help prevent blood clots associated with traumatic injury, doctors need to be able to identify which patients are at increased risk for clotting.
Schneider will assess this risk by using a simple point-of-care blood test called thrombelastography (TEG). Schneider’s study will also test if TEG can determine how long each patient should receive medication to minimize their clot risk. “If we can predict who is at risk of developing blood clots after an injury, we can tailor interventions to prevent them from happening and save the lives of trauma patients across Canada,” says Schneider.
Schneider’s projects is one of 20 UCalgary projects to be awarded funding through the CIHR Fall 2019 Project Grants. Projects were selected based on research deemed to have the greatest potential to advance health-related fundamental or applied knowledge, health research, health care, health systems, and/or health outcomes.
“We are grateful for CIHR’s continued support of science, research, and innovation,” says Dr. Andre Buret, PhD, interim vice-president (research). “The recipients are leaders in their fields, and this investment will enable them to continue the vital work of addressing our country’s most pressing health challenges.”
