AbstractThe number of hip fractures in anticoagulated patients is predicted to increase, due to people living longer. However, evidence regarding urgent perioperative management of elderly patients with hip fracture who take oral anticoagulants (vitamin K antagonists or direct oral anticoagulants) is scarce. In this article, the authors present a narrative review of the evidence to date supporting the urgent management of hip fracture in anticoagulated elderly patients. They discuss the complexity of managing the high risk of procedure-related bleeding and, at the same time, the high risk of thromboembolism. The role of a bridging procedure and the best strategy of anticoagulation reversal are also reviewed. Further studies are required to improve the evidence in urgent surgery, especially in frail elderly patients.

Proportional Incidence

Abstract Background Falls from standing are common in the elderly and are associated with a significant risk of bleeding. We have compared the proportional incidence of bleeding complications in patients on either direct oral anticoagulants (DOAC) or vitamin K antagonists (VKA). Methods Our retrospective cohort study compared elderly patients (≥65 years) on DOAC or VKA oral anticoagulation who presented at the study site – a Swiss university emergency department (ED) – between 01.06.2012 and 01.07.2017 after a fall. The outcomes were the proportional incidence of any bleeding complication and its components (e.g. intracranial haemorrhage), as well as procedural and clinical parameters (length of hospital stay, admission to intensive care unit, in-hospital-mortality). Uni- and multivariable analyses were used to compare the studied outcomes. Results In total, 1447 anticoagulated patients were included – on either VKA (n = 1021) or DOAC (n = 426). There were relatively more bleeding complications in the VKA group (n = 237, 23.2%) than in the DOAC group (n = 69, 16.2%, p = 0.003). The difference persisted in multivariable analysis with 0.7-fold (95% CI: 0.5–0.9, p = 0.014) lower odds for patients under DOAC than under VKA for presenting with any bleeding complications, and 0.6-fold (95% 0.4–0.9, p = 0.013) lower odds for presenting with intracranial haemorrhage. There were no significant differences in the other studied outcomes. Conclusions Among elderly, anticoagulated patients who had fallen from standing, those under DOACs had a lower proportional incidence of bleeding complications in general and an even lower incidence of intracranial haemorrhage than in patients under VKAs.

Bleeding Events

BACKGROUND Direct oral anticoagulants (DOAC) are increasingly used in patients with Non Valvular Atrial Fibrillation (NVAF) for stroke prevention. However, Follow-Up (FU) and dosing these agents in the elderly can be challenging due to different factors, such as chronic kidney disease, frailty, falls, multifactorial anemia and concomitant polypharmacy. These factors in elderly patients predisposes to both thromboembolic and bleeding events once atrial fibrillation occurs. Therefore, balancing risks and benefits of antithrombotic strategies in older populations is crucial. Despite recent increases in DOAC use in NVAF, there are still limited data regarding DOACs effectiveness and safety in frail elderly patients. AIM To assess the effectiveness and safety according to DOAC or Vitamin K Antagonist (VKA) in a cohort of elderly patients with NVAF. METHODS From April 2016 to April 2019, we consecutively included NVAF elderly patients (≥80 years-old) treated with DOAC or VKA in a prospective multicenter registry. Demographic, laboratory, frailty risk stratification and antithrombotic therapy data were collected. Patients had a minimum FU of 6 months. VKA patients had a standard FU through digital international normalized ratio (INR) control and the efficacy of therapy was determined by the time in therapeutic range (TTR) values from the preceding 6 months of treatment using Rosendaal's method. FU in DOAC patients was performed through structured and integral assessment following the Tromboc@t Working Group recommendations for management in patients receiving DOAC (Olivera et al, Med Clin 2018). Key practical management aspects are listed in the flow chart (Figure 1). Clinical Frailty Scale (CFS score) was assigned to each patient at the beginning and during the FU; patients were classified into three categories: non-frail (CFS 1-4), mild-to-moderately frail (CFS 5-6), and severely frail (CFS 7-9). RESULTS From a total of 1040 NVAF patients, 690 (63.5%) were treated with DOAC (61 dabigatran, 95 rivaroxaban, 254 edoxaban and 280 apixaban) and 350 with VKA. In the VKA group, the mean TTR was 52.8%. Demographic characteristics and CFS score are summarized in table 1. Kaplan-Meier analysis (median FU: 16.5 months) showed a significantly high incidence of stroke/systemic embolism among VKA patients vs DOAC patients (4.2 vs 0.5 events per 100 patient-years, p<0.001). Major bleeding in the DOAC group was significantly infrequent compared with VKA group (2.2 vs 8.9 events, p=0.001). In the DOAC group, 90% (n=20/22) of the major bleedings were gastrointestinal [16 rivaroxaban and 4 edoxaban]. However, in the VKA group 64% (n = 20/31) were gastrointestinal, 25.8% (n= 8/31) intracranial and 9.7% (n = 3/31) urogenital bleedings. We identified 365 very elderly patients (aged ≥ 90 years) of which 270 (39.1%) were DOAC patients and 95 (27.1%) VKA patients. In this subgroup of patients, after a multivariate regression analysis, the stroke/systemic embolism incidence was similar in both treatment groups regardless of the age, but major bleeding decreased significantly in DOAC group (adjusted HR 0.247, 95% CI 0.091-0.664). CONCLUSIONS Our data indicate that DOACs can be a good therapeutic option for stroke/systemic embolism prevention in frail elderly patients, showing low rates of stroke as well as bleeding events when a structured and integral FU is applied to anticoagulated patients. Further investigations are necessary to analyze the impact in the quality of life and net clinical benefit of anticoagulant therapy when a FU program is applied in elderly patients.

Study Population

We compared the risks of switching to another oral anticoagulant (OAC) and discontinuation of direct oral anticoagulants (DOACs) among elderly patients with nonvalvular atrial fibrillation (NVAF) who were prescribed rivaroxaban or dabigatran versus apixaban. Patients (≥65 years of age) with NVAF prescribed DOACs (January 1, 2013 to September 30, 2017) were identified from the Humana research database and grouped into DOAC cohorts. Cox regression analyses were used to evaluate whether the risk for switching to another OAC or discontinuing index DOACs differed among cohorts. Of the study population (N = 38 250), 55.9% were prescribed apixaban (mean age: 78.6 years; 49.8% female), 37.3% rivaroxaban (mean age: 77.4 years; 46.7% female), and 6.8% dabigatran (mean age: 77.0 years; 44.0% female). Compared to patients prescribed apixaban, patients prescribed rivaroxaban (hazard ratio [HR]: 2.08; 95% confidence interval [CI], 1.92-2.25; P < .001) or dabigatran (HR: 3.74; 95% CI, 3.35-4.18, P < .001) had a significantly higher risk of switching to another OAC during the follow-up; compared to patients prescribed apixaban, the risks of discontinuation were also higher for patients treated with rivaroxaban (HR: 1.10; 95% CI, 1.07-1.13, P < .001) or dabigatran (HR: 1.29; 95% CI, 1.23-1.35, P < .001).

Heparin Induced Thrombocytopenia

SummaryHeparin induced thrombocytopenia (HIT) is a prothrombotic syndrome initiated by platelet-activating auto-antibodies with potentially devastating complications. Once the diagnosis of HIT is suspected, discontinuation of heparin and treatment with an alternative anticoagulant are mandatory. While established drugs for HIT are no longer available, parenteral factor Xa inhibitors, thrombin inhibitors and perhaps the direct oral anticoagulants provide additional treatment options. The aim of this review was to highlight the current clinical aspects regarding HIT focusing on the role of novel medications.
