The Risk of Thromboembolic Events in Surgically Treated Hip Fracture: A Retrospective Cohort Study
Description
The presentation begins with Philippe Beauchamp-Chalifour, a first-year resident at Laval University, introducing himself and acknowledging the support from the Canadian Institutes of Health Research for his Master Scholarship. He addresses the growing societal burden of hip fractures and the associated risks of thromboembolic events (TEV), noting the routine thromboprophylaxis administered to patients undergoing surgery for these injuries. The risk of TEV at three months post-surgery is reported to be 5%, higher than previous data, which indicated a risk of only 1-2%. Philippe outlines a retrospective cohort study conducted in Quebec City, examining over 6,000 cases, ultimately including around 5,000 patients aged 65 and older who underwent hip fracture surgeries in the past decade.
He presents the main findings: with an average patient age of 83, the study highlighted a mortality rate of 8.4% within three months. The risk of bleeding, complicating treatment due to thromboprophylaxis, is found to be 6%, primarily manifested as hematomas. Factors influencing TEV risk included COPD, past medical history of TEV, and renal failure, while atrial fibrillation appeared to provide a protective effect, likely due to anticoagulation treatments. The reoperation rate was noted at 12%.
In conclusion, Philippe emphasizes the necessity for a reevaluation of thromboprophylaxis management strategies in elderly patients with respect to surgical interventions for hip fractures, highlighting the unexpected higher incidence of symptomatic TEV and stressing areas for future research.
