Abstract:
Background: Direct Oral Anti-Coagulants (DOACs) decrease the risk of Venous Thromboembolism (VTE) without
increasing the risk of bleeding in elective lower limb orthopedic surgery. However, the role of DOACs in
preventing VTE following hip fracture surgery in the elderly remains unclear. This study aims to evaluate the
efficacy and safety of DOACs in elderly patients undergoing surgery for hip fracture.
Methods: Single-center, retrospective, matched cohort study of patients receiving either a DOAC or Low Molecular
Weight Heparin (LMWH) for VTE prophylaxis following hip fracture surgery.
Data obtained: Patient demographics, co-morbidities, fracture classification, time to surgery, procedure performed
and length of stay.
Outcomes Assessed: Incidence of VTE, incidence of major haemorrhage and death within 30 days of surgery.
Results: A total of 108 patients (DOAC group = 54, LMWH group = 54) were included. The incidence of VTE
was comparable between the DOAC and LMWH groups at 0% and 7.4% respectively (RR: 0.11, 95% CI: 0.01 to
2.02, p= 0.14). Haemorrhage occurred in 7.4% of patients in the DOAC group and 5.6% of patients in the LMWH
group (RR: 1.33, 95% CI: 0.31 to 5.68, p= 0.70). Mortality from VTE was 0% in the DOAC group and 1.9% in the
LMWH group (RR: 0.33, 95% CI: 0.01 to 8.01, p = 0.49). Mortality from haemorrhage was 1.9% in both the DOAC
and LMWH groups (RR: 1.00, 95% CI: 0.06 to 15.58, p = 0.99).
Conclusion: This study demonstrates comparable efficacy and safety of DOACs with LMWH in the prevention
of VTE following surgery for hip fracture in the elderly. This can be achieved with careful patient selection. Future
studies are required to identify patients who stand to benefit the most from treatment.
