Abstract

Background: Venous thromboembolism (VTE) is one of the most common complications of hip fracture surgeries, and it is unclear whether delayed surgery affects the incidence of VTE. This study aimed to examine the association between delayed surgery and VTE incidence by statistically adjusting for factors that may influence VTE incidence.

Methods: We included 862 patients ≥ 65 years with hip fractures who underwent surgery between October 2010 and December 2020. We examined the effect of surgical delay 48 h after injury on postoperative VTE. Patients with and without VTE were assigned to groups V and NV, respectively. Those with and without proximal deep venous thrombosis (DVT) were assigned to PD and NPD groups, respectively. Univariate analysis was performed to identify factors that might influence DVT development. Risk factors for developing VTE and proximal DVT were analyzed using logistic regression analysis to determine whether delayed surgery was a risk factor.

Results: VTE was observed in 436 patients (40%) and proximal DVT in 48 patients (5.6%). Univariate analysis showed significant differences in the time from trauma to surgery between the V and NV groups and between the PD and NPD groups. In multivariate analysis, surgery 48 h later was also a risk factor for developing VTE and proximal DVT.

Conclusion: A delay in surgery beyond 48 h after a hip fracture injury is a risk factor for developing VTE and proximal DVT.
