Abstract
IntroductionSurgical intervention within 48 h of admission in patients with acute hip fractures has been associated to lower morbidity and mortality. Patients anticoagulated with vitamin K antagonists (VKAs) have longer time to corrective surgery than those not anticoagulated. Sparse data exists on time to surgery (TTS) in patients taking direct oral anticoagulants (DOACs). The aim of this study is to establish TTS among non-anticoagulated and anticoagulated patients taking either VKA or DOAC. Materials and methodsWe conducted a retrospective cohort study of consecutive patients admitted with acute hip fracture between July 1, 2016 and December 31, 2017. Patient-, anticoagulant- and surgery-related characteristics were collected. The primary outcome was TTS calculated from time of admission. Median TTS with interquartile range (IQR) was compared among 3 groups of patients: DOAC, VKA and No OAC. ResultsA total of 472 patients were included: 12.5% (59/472) were anticoagulated (28/472 on VKAs and 31/472 on DOACs). Median TTS was longer in the VKA group [64 h (IQR: 50–84)] and in the DOAC group [(61 h; IQR: 42 to 77)] versus the No OAC group [44 h (IQR: 28–63), p = 0.0006 and p = 0.003 respectively]. There was no significant difference in median TTS in the VKA group versus the DOAC group (p = 0.6396). ConclusionPatients taking either VKA or DOAC have significant delays to emergency hip fracture surgery compared to those not anticoagulated. Future studies aimed at examining this relationship more closely are warranted. In the meantime, an action plan aimed at early identification and appropriate management of anticoagulation in this vulnerable group of patients is necessary.
