Is It Safe to Resume Direct Oral Anticoagulants upon Discharge after Hip Fracture Surgery? A Retrospective Study

This study aimed to examine the incidence rate of early reoperations following hip fracture surgery and determine the safety of resuming direct oral anticoagulants. Many orthopedic surgeons are reluctant to resume chronic anticoagulation therapy for patients after surgical intervention for hip fractures. One of the main reasons is the potential for reoperation in the case of surgical complications. We conducted a retrospective cohort study at an Academic Level I trauma center, reviewing the records of 425 geriatric patients (age > 60) who underwent hip fracture surgery between 2018 and 2020, including a subgroup treated with direct oral anticoagulants prior to hospitalization. The study assessed the incidence rate of complications requiring early reoperation. Out of the 425 patients, only nine (2%) required reoperation within a month after discharge, with two (0.5%) on chronic anticoagulation therapy. None of the reoperations were urgent, and all were performed at least 24 h after re-admission. The findings revealed a very low incidence rate of reoperations in patients who underwent hip fracture surgery, with no reoperations performed within 24 h of re-admission. Consequently, we believe that resuming chronic direct oral anticoagulants is a safe and effective approach when discharging patients after hip fracture surgery.
