Abstract
Hip fracture is a common serious injury among older adults, yet the management of hip fractures for patients taking direct oral anticoagulants remains inconsistent worldwide. Drawing from a synthesis of available evidence and expert opinion, best practice approaches for managing patients with a hip fracture and who are taking direct oral anticoagulants pre-operatively were considered by a working group of the Fragility Fracture Network Hip Fracture Audit Special Interest Group. The literature and related clinical guidelines were reviewed and a two-round modified Delphi study was conducted with a panel of experts from 16 countries and involved seven clinical specialities. Four consensus statements were achieved: peripheral nerve blocks can reasonably be performed on presentation for patients with hip fracture who are receiving direct oral anticoagulants; hip fracture surgery can reasonably be performed for patients taking direct oral anticoagulants < 36 h from last dose; general anaesthesia could reasonably be administered for patients with hip fracture and who are taking direct oral anticoagulants < 36 h from last dose (assuming eGFR > 60 ml.min-1.1.73 m-2); and it is generally reasonable to consider recommencing direct oral anticoagulants (considering blood loss and haemoglobin) < 48 h after hip fracture surgery. No consensus was achieved regarding timing of spinal anaesthesia. The consensus statements were developed to aid clinicians in their decision-making and to reduce practice variations in the management of patients with hip fracture and who are taking direct oral anticoagulants. Each statement will need to be considered specific to each individual patient's treatment.

Abstract
Hip fractures are an increasingly common injury in the senior population and almost always require surgical fixation or prosthetic replacement. These surgeries, according to the American Academy of Orthopaedic Surgeons, are considered high-risk for bleeding, especially in a population fraught with comorbidities and often presenting on anticoagulation medications. Direct oral anticoagulants represent a class of drugs that have been becoming more popular in use in this population, with many benefits over the historically used Warfarin. There are recommendations for preoperative discontinuation and postoperative resumption of these medications, which can be more readily managed for elective surgeries. However, there is a paucity of literature detailing best practice guidelines for the perioperative management of direct oral anticoagulants when a patient presents with a hip fracture. This review article summary of the periprocedural management of DOACs for hip surgery was developed by examining the American College of Chest Physicians evidence-based clinical practice guidelines, Perioperative Guidelines on Antiplatelet and Anticoagulant Agents written by anesthesiologists, various retrospective studies, and drug labels for pharmacokinetic data. These recommendations should be used as a guideline, along with the collaboration of multidisciplinary hospital teams during inpatient admission, to manage these complex patients.

Should recommended laboratory-test cut-offs allowing surgery be followed for proximal femoral fractures in patients on direct oral anticoagulant therapy? Orthop Traumatol Surg Res 2024; 110:103819. [PMID: 38278346 DOI: 10.1016/j.otsr.2024.103819] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2021] [Revised: 07/10/2023] [Accepted: 10/11/2023] [Indexed: 01/28/2024]
Abstract
BACKGROUND Proximal femoral fractures (PFFs) in elderly patients must receive prompt surgical treatment. Optimal PFF-surgery timing in patients on direct oral anticoagulant (DOA) therapy is a specific but common clinical issue. Recommendations exist about the anti-Xa or anti-IIa levels and creatinine clearance values required to allow surgery. The objectives of this study in patients older than 75 years who required PFF surgery were to evaluate bleeding when the recommendations were versus were not applied and to assess concordance between DOA-activity-assay results and creatinine clearance used to help determine the wait to surgery. HYPOTHESIS Peri-operative bleeding is more marked when surgery is performed while the DOA is still active. PATIENTS AND METHODS This single-centre, retrospective, comparative, observational study included 87 patients older than 75 years who required arthroplasty or intra-medullary nailing for PFF and were taking DOA therapy. Surgery was performed after versus before the laboratory-test results fell below the recommended cut-offs in 68 patients (Rec+ group) versus 19 patients (Rec- group), respectively. The study outcomes were blood loss estimated using the Mercuriali's formula and the proportion of patients requiring post-operative blood transfusions. RESULTS Mean blood loss was 287.1mL in the Rec+ group and 411.7mL in the Rec- group (p=0.12). Blood transfusions were required by a post-operative haemoglobin level below 0.8g/dL in 11 (16.2%) Rec+ patients and 6 (31.6%) Rec- patients (p=0.2). Concordance was poor between DOA activity and creatinine clearance (Cohen's κ, 0.16; p=0.146). DISCUSSION Peri-operative bleeding was not significantly more severe when PFF surgery was performed while DOA therapy was still active. These data suggest that PFF surgery within 48h may be appropriate in patients older than 75 years on DOA therapy. LEVEL OF EVIDENCE IV; retrospective single-centre study.

Abstract
OBJECTIVES To compare outcomes in patients on direct oral anticoagulants (DOACs) treated within 48 hours of last preoperative dose with those with surgical delays >48 hours. METHODS DESIGN Retrospective cohort study. SETTING Three academic Level 1 trauma centers. PATIENT SELECTION CRITERIA Patients 65 years of age or older on DOACs before hip fracture treated between 2010 and 2018. Patients were excluded if last DOAC dose was >24 hours before admission, patient suffered from polytrauma, and/or delay to surgery was not attributed to DOAC. OUTCOME MEASURES AND COMPARISONS Primary outcome measures were the postoperative complication rate as determined by diagnosis of deep venous thrombosis or pulmonary embolus, wound breakdown, drainage, or infection. Secondary outcomes included transfusion requirement, perioperative bleeding, length of stay, reoperation rates, readmission rates, and mortality. RESULTS Two hundred five patients were included in this study, with a mean cohort age of 81.9 years (65-100 years), 64% were (132/205) female, and a mean Charlson Comorbidity Index of 6.4 (2-20). No significant difference was observed among age, sex, Charlson Comorbidity Index, or fracture pattern between cohorts (P > 0.05 for all comparisons). Seventy-one patients had surgery <48 hours after final preoperative DOAC dose; 134 patients had surgery >48 hours after. No significant difference in complication rate between the 2 cohorts was observed (P = 0.30). Patients with delayed surgical management were more likely to require transfusion (OR 2.39, 95% CI, 1.05-5.44; P = 0.04). Patients with early surgical management had significantly shorter lengths of stay (5.9 vs. 7.6 days, P < 0.005). There was no difference in estimated blood loss, anemia, reoperations, readmissions, 90-day mortality, or 1-year mortality (P > 0.05 for all comparisons). CONCLUSIONS Geriatric patients with hip fracture who underwent surgical management within 48 hours of their last preoperative DOAC dose required less transfusions and had decreased length of stay, with comparable mortality and complication rates with patients with surgery delayed beyond 48 hours. Providers should consider early intervention in this population rather than adherence to elective procedure guidelines. LEVEL OF EVIDENCE Prognostic Level III.

Abstract
PURPOSE To assess the relationship between anticoagulant use and rehabilitation outcomes in post-acute hip fracture patients. METHODS A retrospective study (1/2017 to 5/2019) of 299 hip fractured patients. OUTCOME MEASURES Functional Independence Measure (FIM) and the motor FIM's effectiveness. RESULTS Patients treated with anticoagulation drugs exhibited a significant longer latency time from fracture to surgery (U = -4.37, p < 0.001) and from surgery to rehabilitation (U=-2.27, p = 0.023), and a significantly higher rate of cardiovascular diseases (χ2=0.15, p= 0.023) compared with untreated patients. No significant differences between the two patient groups were found regarding the rate of blood transfusions, perioperative complications (infections, reoperation), or functional outcome measures. CONCLUSIONS Oral anticoagulants are not associated with rehabilitation outcomes of hip fracture patients.Implications rehabilitationAnticoagulation drug use is not associated with functional outcome of post-acute hip fracture patients.It is recommended to renew oral anticoagulants for patients on chronic treatment after surgery since no negative outcomes were found during rehabilitation under anticoagulant treatment and in light of the importance of these drugs in preventing thromboembolic complications.

Abstract
BACKGROUND Early hip fracture surgery is recommended to decrease mortality, however the impact of a delay in surgery due to previous treatment with direct oral anticoagulants (DOA) is unknown. Our objective was to determine if early surgery, defined as surgery within 48 h of hospital admission is associated with decreased postoperative mortality. We tested the hypothesis that early surgery was beneficial with regard for mortality in patients treated with direct oral anticoagulants. METHODS Retrospective cohort study in a French University Hospital including patient admitted for Hip fracture. The main exposure was wait time for surgery defined as the total time, in hours, between hospital admission and surgery. The main outcome was mortality within 30 days after hip fracture surgery. RESULTS In 3429 patients, the overall 30-day mortality was 4.1% (95% CI 3.5%; 4.9%). In DOA + patients, the 30-day mortality rates in the early and delayed surgery groups were 1.2% and 5.9%, respectively, with estimated risk difference of -4.4 (with a 2% probability of this difference is > 0). In the DOA + group, early surgery tended to be associated with a higher percentage receiving red-blood cells (64.6% vs 54.8%, respectively, estimated risk difference of 9.9% with a 93% probability of this difference is > 0) and lower risk of pneumonia (1.2% vs 8.2%, respectively; estimated difference of -6.7% with 0.3% probability of superiority). CONCLUSION Early hip fracture surgery was associated with improved survival in patients previously treated with DOAs.

Abstract
Objectives Hip fractures represent a prevalent geriatric cause of morbidity and mortality. The presence of multiple comorbidities requiring the use of an anticoagulant or antiplatelet medication adds complexity to management and influences outcomes. International guidelines suggest expedited surgery within 48 h; however, anticoagulant and antiplatelet medications commonly cause delays. Research exploring health outcomes in this group is unclear. Therefore, we aimed to determine the impact of anticoagulant and antiplatelet medications on operative delay and overall complications in hip fracture patients. Methods A retrospective cohort study of hip fractures was performed at a tertiary hospital over a 3-year period from 1st January 2018 to 31st December 2020. Data collected included demographics, time to surgery, length of stay, postoperative blood transfusion, venous thromboembolism, acute coronary syndrome, stroke, infections in hospital and 120-day mortality. Patients were categorised based on the use of direct oral anticoagulants, warfarin and antiplatelet medications. Results In total, 474 patients were included and 43.5% were on an anticoagulant or antiplatelet medication. Patients on these medications had more than twice the rate of operative delay (41.7% versus 17.2%, p < 0.001) with the greatest in the direct oral anticoagulant group (92.7% delay). After controlling for age and gender, this was still significant for direct oral anticoagulant (p < 0.001) and antiplatelet group patients (p = 0.02). These patients also had a 20% increased overall complication rate (p < 0.001). On subgroup logistic regression, the increased complication rate was noted in the direct oral anticoagulant group (p = 0.006) and the antiplatelet group (p < 0.001) but not in the warfarin group (p = 0.25). Time to surgery beyond 48 h was associated with a double increase in the odds of a postoperative complication (p = 0.005). Conclusion There is a significantly greater delay to surgery in hip fracture patients on anticoagulant or antiplatelet medications as well as a higher incidence of complications. Guidelines to expedite early safe surgery in this high-risk patient group are required.

Abstract
PURPOSE The prevalence of proximal femur fractures is increasing with rising population age. Patients are presenting with more comorbidities. Anticoagulants create a challenge for the necessary early surgical procedure (osteosynthesis or arthroplasty). Our aim was to investigate the influence of anticoagulants on in-house mortality after surgical treatment of proximal femoral fractures. METHODS A retrospective single-centre study was conducted including 1933 patients with an average age of 79.8 years treated operatively for a proximal femoral fracture between January 2016 and June 2020. One treatment protocol was performed based on type of anticoagulant, surgery, and renal function. Patient data, surgical procedure, time to surgery, complications and mortality were assessed. RESULTS On average, patients with anticoagulants had a delay to surgery of 41.37 hours vs 22.1 hours for patients without (p < 0.000). Anticoagulants were associated with the occurrence of complications. The total complication rate was 22.4%. Patients with complications showed a prolonged time to surgery in comparison to those without (28.9 h vs 24.9 h; p < 0.00). In-house mortality rate was 4% and twice as high for patients on anticoagulants (7.7%; p < 0.00). Whilst there was no significant difference in the mortality rate between surgery within 24 and 48 hours (2.9% vs. 3.8%; p < 0.535), there was a significant increase in mortality of patients waiting more than 48 hours (9.8%; p < 0.001). CONCLUSIONS Pre-existing anticoagulant therapy in patients with proximal femur fractures is associated with a higher mortality rate, risk of complications and prolonged hospital stay. Further influential factors are age, gender, BMI and time to surgery.

Time to surgery and complications in hip fracture patients on novel oral anticoagulants: a systematic review. Arch Orthop Trauma Surg 2022; 142:633-640.

Abstract
BACKGROUND Early surgery has been consistently demonstrated to reduce complications and mortality in hip fracture patients. There remains no general consensus, however, regarding the optimal time to surgery for hip fracture patients who are on novel oral anticoagulants (NOAC) on admission and its effect on clinical outcomes after surgery. The objective of this review was to assess the effect of preoperative NOAC therapy on time to surgery and postoperative complications in hip fracture patients. METHODS We performed a systematic review of the literature using the PubMed, Embase, and Cochrane Library electronic databases. Relevant articles were identified and included if they: (i) included patients on NOAC therapy on admission who did not undergo reversal; (ii) included a control group of patients not on any anticoagulation; (iii) included time from admission to surgery; and (iv) included one of the following outcomes: blood transfusion, venous thromboembolism (VTE), stroke, readmission, and mortality. RESULTS Nine studies were included with a total of 4,419 patients. There were 414 NOAC patients and 4,005 non-anticoagulated patients. Six of the nine studies found a significant increase in time to surgery for patients on NOAC therapy. Three of the seven studies that reported rates of blood transfusion found a significantly higher incidence of transfusion in patients on NOACs. None of the studies found a significant difference in VTE and stroke. One of the two studies that reported readmissions showed a higher risk of readmission for patients on NOACs. Eight of the nine included studies found no significant difference in postoperative mortality rates between the NOAC and control groups, with the remaining study finding a higher mortality rate only in patients on NOAC therapy who underwent fixation and not those who underwent arthroplasty. CONCLUSIONS These mixed findings suggest that delay to surgery may not be warranted in the urgent surgical setting of patients on NOAC therapy who sustain hip fractures.

Abstract
Purpose To synthesise the evidence on the impact of pre-operative direct oral anticoagulants (DOACs) on health outcomes for patients who sustain a hip fracture. Method A rapid systematic review of three databases (MEDLINE, Embase and Scopus) for English-language articles from January 2000 to August 2021 was conducted. Abstracts and full text were screened by two reviewers and articles were critically appraised. Data synthesis was undertaken to summarise health outcomes examined for DOAC users versus a no anticoagulant group. Key information was extracted for study type, country and time frame, population and sample size, type of DOACs, comparator population(s), key definitions, health outcome(s), and summary study findings. Results There were 21 articles identified. Of the 18 studies that examined time to surgery, 12 (57.1%) found DOAC users had a longer time to surgery than individuals not using anticoagulants. Five (83.3%) of six studies identified that DOAC users had a lower proportion of surgery conducted within 48 h Four (40.0%) of ten studies reporting hospital length of stay (LOS) identified a higher LOS for DOAC users. Where reported, DOAC users did not have increased mortality, blood loss, transfusion rates, complication rates of stroke, re-operation or readmissions compared to individuals not using anticoagulants. Conclusions The effect of DOAC use on hip fracture patient health was mixed, although patients on DOACs had a longer time to surgery. The review highlights the need for consistent measurement of health outcomes in patients with a hip fracture to determine the most appropriate management of patients with a hip fracture taking DOACs.

[PMID: 34548147 DOI: 10.1016/j.injury.2021.09.005] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/12/2021] [Revised: 07/15/2021] [Accepted: 09/05/2021] [Indexed: 02/02/2023]
Abstract
BACKGROUND Increasing numbers of patients are taking Direct Oral Anticoagulants at the time of hip fracture. Evidence is limited on how and if the effects of DOAC's should be reversed before surgical fixation. Wide variations in practice exist. We conducted a systematic review to investigate outcomes for three reversal strategies. These were: "watch and wait" (also referred to as "time-reversal"), plasma product reversal and reversal with specific antidotes. METHODS A systematic search was conducted using multiple databases. Results were obtained for studies directly comparing different DOAC reversal strategies in hip fracture patients and for studies comparing DOAC-taking hip fracture patients (including patients "reversed" using any method and "non-reversed" patients) against matched controls taking either a vitamin-K antagonist or not receiving anticoagulation therapy. This allowed construction of a network meta-analysis to indirectly compare outcomes between "reversed" and "non-reversed" DOAC patients. With respect to "watch and wait"/"time-reversal", a cut-off time to surgery of 36 hours was used to distinguish between "time-reversed" and "non time-reversed" DOAC patients. The primary outcome was early/inpatient mortality, reported as Odds Ratios (OR). RESULTS No studies investigating plasma products or reversal agents specifically in hip fracture patients were obtained. Fourteen studies were suitable for analysis of "watch and wait"/"time- reversal". Two studies directly compared "time-reversed" and "non time-reversed" DOAC-taking hip fracture patients (58 "time-reversed", 62 "non time-reversed"). From 12 other studies we used indirect comparisons between "time-reversed" and "non time-reversed" DOAC patients (total, 357 "time-reversed", 282 "non time-reversed"). We found no statistically significant differences in mortality outcomes between "time-reversal" and "non time-reversal" (OR 1.48 [95%CI: 0.29-7.53]). We also did not find a statistically significant difference between "time reversal" and "non time-reversal" in terms of blood transfusion requirements (OR 1.16 [95% CI 0.42-3.23]). However, several authors described that surgical delay is associated with worse outcomes related to prolonged hospitalisation, and that operating within 36 hours is safe. CONCLUSIONS We suggested against "watch and wait" to reverse the DOAC effect in hip fractures. Further work is required to assess the optimal timing for surgery as well as the use of plasma products or specific antidotes in DOAC-taking hip fracture patients.

Abstract
AIMS Current guidelines recommend surgery within 48 hours among patients presenting with hip fractures; however, optimal surgical timing for patients on oral anticoagulants (OACs) remains unclear. Individual studies are limited by small sample sizes and heterogeneous outcomes. The aim of this study was to conduct a systematic review and meta-analysis to summarize the effect of pre-injury OACs on time-to-surgery (TTS) and all-cause mortality among older adults with hip fracture treated surgically. METHODS We searched MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials (CENTRAL) from inception to 14 October 2019 to identify studies directly comparing outcomes among hip fracture patients receiving direct oral anticoagulants (DOACs) or vitamin K antagonists (VKAs) prior to hospital admission to hip fracture patients not on OACs. Random effects meta-analyses were used to pool all outcomes (TTS, in-hospital mortality, and 30-day mortality). RESULTS A total of 34 studies (involving 39,446 patients) were included in our systematic review. TTS was 13.7 hours longer (95% confidence interval (CI) 9.8 to 17.5; p < 0.001) among hip fracture patients on OACs compared to those not on OACs. This translated to a three-fold higher odds of having surgery beyond the recommended 48 hours from admission (odds ratio (OR) 3.0 (95% CI 2.1 to 4.3); p = 0.001). In-hospital mortality was higher (OR 1.4 (95% CI 1.0 to 1.8); p < 0.03) among anticoagulated patients. Among studies comparing anticoagulants, there was no statistically significant difference in time-to-surgery between patients taking a DOAC compared to a VKA. CONCLUSION Patients presenting with a hip fracture who were taking OACs prior to injury experience a delay in time-to-surgery and higher mortality than non-anticoagulated patients. Patients on DOACs may be at risk of further delays. Evaluating expedited surgical protocols in hip fracture patients on OACs is an urgent priority, with the potential to decrease morbidity and mortality in this group of high-risk patients.

Abstract
OBJECTIVE Currently, there are no national protocols in place for managing hip fracture patients on direct oral anticoagulants (DOACs). Hence, various local management protocols exist. We compared three different local protocols and a control group to assess blood loss and time delay to theatre. METHODS Sequential data were collected for 120 hip fracture patients in four groups; wait 24 hours from last dose, wait 48 hours, perform DOAC levels and control. RESULTS DOAC use in our hip fracture patients was 14%. Median haemoglobin (Hb) drop between the three protocol groups showed no significant difference (13.5, 21.5 and 16.0 g/L) (Kruskal-Wallis, p=0.9). Median Hb drop in the control group was 16.0 g/L versus 17.5 g/L in the protocol groups combined (Mann Whitney-U, p=0.7). Average Hb drop in the control group was 19.2 g/L and in the protocol groups was 22.1 g/L; a 15% greater blood loss with DOACs. The frequency distribution of blood loss was different between the control and protocol groups, but not between the protocol groups. The highest Hb drop in the control group was 3.4 g/L, while in the protocol groups, it was 7.8 g/L. Median Hb on arrival to hospital was higher in the control group (124 g/L) compared with the three protocol groups (87 g/L) (t-test p<0.0001). Transfusion rates of up to 40% were observed within the DOAC groups compared with zero in the control group.Median time to theatre between the three protocol groups was significantly different at 17.5, 53.3 and 22.5 hours, respectively (Kruskal-Wallis, p<0.0001). CONCLUSION DOACs caused increased bleeding and delays to theatre in hip fracture patients, however the largest Hb difference was already apparent on arrival. Subsequent blood loss was minimal on average; a few patients bled heavily. Prolonged waiting made no significant difference to blood loss, but caused delay to theatre leading to financial losses from best practice tariff.

Abstract
Background: we aimed to analyze the influence of antithrombotic medication in delaying surgery for fragility hip fractures; Method: a total of 312 consecutive hip fracture cases over 55 years who underwent surgery in our Orthopedic Clinic; Results: of these, 90 patients received chronic antithrombotic medication. There were no differences between the medicated group and controls (n = 222) regarding age, gender, type of fracture and haemoglobin at admittance. However, median time to surgery was significantly longer in the medicated group: 4(3–6) days compared to 2(1–4) (p < 0.0001). By type of medication, time to surgery was: 3(1–4) days for acetylsalicylic acid (n = 44), 6(5.25–7.75) days for clopidogrel (n = 15), 4.5(4–7) days for acenocoumarin (n = 18) and 5(4–7.25) days for novel direct oral anticoagulants (n = 13). The Charlson comorbidity index was significantly higher in the medicated group: 5 [4–5] versus 4 [3–5]. There were no differences in transfusions except for fresh frozen plasma, which was administered more in the medicated patients; Conclusions: the prevalence of platelet aggregation inhibitors and anticoagulant use among fragility hip fracture patients is high, with almost a third using some form of antithrombotic medication. This may significantly lengthen time to surgery.

Abstract
BACKGROUND Hip fracture patients on oral anticoagulants (OACs) experience increased time-to-surgery and higher mortality compared to non-anticoagulated patients. However, it is unclear whether pre-injury OAC status and its associated operative delay are associated with worsening of peri-operative hemostasis or an increased risk of postoperative thromboembolism. METHODS We performed a systematic review to identify studies that directly compared hemostatic and thromboembolic outcomes among hip fracture patients on an OAC prior to admission with those not on anticoagulants. Random effects meta-analyses were used to pool all outcomes of interest (estimated blood loss, transfusion requirements, and postoperative thromboembolism). RESULTS Twenty-one studies involving 21 417 patients were included. Estimated blood loss was higher among patients presenting with OACs compared to those not anticoagulated (mean difference 31.0 mL, 95% confidence interval [CI] 6.2-55.7). Anticoagulated patients also had a 1.3-fold higher risk of receiving red blood cell transfusions (odds ratio [OR] 1.34, 95% CI 1.20-1.51); however, rates of postoperative thromboembolism were similar regardless of anticoagulation status (OR 0.96, 95% CI 0.40-2.79 for venous thromboembolism; OR 0.58, 95% CI 0.25-1.36 for arterial thromboembolism). No subgroup effect was found based on anticoagulant type or degree of surgical delay. CONCLUSION Hip fracture patients on OACs experience increased surgical blood loss and higher risk of red blood cell transfusions. However, the degree of surgical delay did not mitigate this risk, and there was no difference in postoperative thromboembolism. The impact of appropriate, timely OAC reversal on blood conservation and expedited surgery in anticoagulated hip fracture patients warrants urgent evaluation.

Early Surgical Fixation for Hip Fractures in Patients Taking Direct Oral Anticoagulation: A Retrospective Cohort Study. Geriatr Orthop Surg Rehabil 2020; 11:2151459320944854.

Abstract
Introduction: Currently, evidence-based guidelines regarding delay to theatre for urgent
surgical intervention in patients taking direct oral anticoagulants (DOACs)
are lacking. Therefore, this study aims to investigate the effect of DOACs
on patient outcomes receiving early (<48 hours) versus delayed (>48
hours) surgery for neck of femur fractures. Methods: A retrospective cohort study was conducted at a tertiary teaching hospital.
Treatment groups were hip fracture patients taking DOACs on admission and
receiving surgery in <48 hours (n = 17) and >48 hours (n = 11). A
control cohort of hip fracture patients not taking DOACs (n = 56) was
matched to the <48 hours treatment group for comparison. Patient
demographics were recorded and key outcome measures included perioperative
hemoglobin levels, transfusion rates, time to surgery, 90-day mortality,
hematoma rates, and length of stay in hospital. Results: There was no significant difference in perioperative hemoglobin levels,
transfusion rates, or hematoma between groups. Patients taking DOACs and
receiving early surgery had significantly longer time to surgery compared to
the non-DOAC control (32.21 ± 7.83 vs 25.98 ± 11.4, P =
.01). No deaths were recorded in the early DOAC group at 90 days, compared
to 4 (36%) in the late DOAC group (P = .04). Discussion and Conclusions: Our study suggests hip fracture patients taking DOACs on admission is not a
reason to delay surgery. However, given the lack of literature in this area,
further prospective research with larger patient numbers is required to
definitively guide clinical practice.
