BACKGROUND: Venous thromboembolism (VTE) is a frequent complication in critically ill patients, who often have multiple risk factors. Pharmacological thromboprophylaxis is widely applied to lower this risk, but guidelines lack dosing recommendations. OBJECTIVE: This survey aims to assess current thromboprophylaxis preferences and willingness to participate in future randomized clinical trials (RCTs) on this topic. METHOD: We conducted an international online survey between February and May 2023 among intensive care unit (ICU) physicians, including 16 questions about preferences in relation to thromboprophylaxis and preferences on topics for a future RCT. The survey was distributed through the network of the Collaboration for Research in Intensive Care. RESULTS: A total of 715 physicians from 170 ICUs in 23 countries contributed information, with a mean response rate of 36%. In most ICUs, both pharmacological (n = 166, 98%) and mechanical thromboprophylaxis (n = 143, 84%) were applied. A total of 36 pharmacological thromboprophylaxis regimens were reported. Use of low-molecular-weight heparin (LMWH) was most common (n = 149 ICUs, 87%), followed by subcutaneous unfractionated heparin (n = 44 ICUs, 26%). Seventy-five percent of physicians indicated that they used enoxaparin 40 mg (4000 IU), dalteparin 5000 IU, or tinzaparin 4500 IU once daily, whereas 25% reported the use of 16 other LMWH type and dose combinations. Dose adjustment according to weight was common (78 ICUs, 46%). Participants perceived high variation in the application of thromboprophylaxis and were willing to consider an alternative LMWH type (n = 542, 76%) or dose (n = 538, 75%) in the context of an RCT. CONCLUSION: LMWH was the preferred agent for thromboprophylaxis in critically ill patients. There was considerable variation in the application of LMWH for prophylaxis, reflected by the use of different types, doses, and dosing strategies. Most physicians would be willing to participate in an RCT on thromboprophylaxis. EDITORIAL COMMENT: This survey demonstrates current patterns in implementation preferences for critically ill patients. While there is one approach and drug that is commonly preferred, these findings show that there is some variation in practice.

BACKGROUND: Unfractionated heparin is used as the most common anticoagulation for venovenous extracorporeal membrane oxygenation (VV ECMO) patients. However, it is accompanied by frequent bleeding and thrombotic complications. The aim of the study was to demonstrate the feasibility of Enoxaparin anticoagulation for VV ECMO patients. METHODS: This study is a retrospective analysis of VV ECMO patients on continuous intravenous Enoxaparin anticoagulation. The primary outcome was the incidence of bleeding, thrombotic, and neurological complications during ECMO support. The secondary outcome was an analysis of secondary and primary hemostasis profiles. RESULTS: Data from 38 patients were analyzed in this study. The incidence of bleeding complications was 5.3%, for thrombotic complications it was 2.6% and for neurological (bleeding/ischemic events) complications it was 10.5%. The targeted anti-Xa activity of 0.4-0.6 IU/mL was achieved and maintained during whole ECMO period in 28 patients (73.8%), not affecting the hemocoagulation profile represented by APTT-r 1.15 ± 0.2, TT 18.67 ± 3.35 s, PT/INR 1.21 ± 0.19, fibrinogen 5.39 ± 1.49 g/L, antithrombin, and platelet count. Primary hemostasis pathology was diagnosed in all patients by PFA 200 tests Col/EPI 279 ± 38 s and Col/ADP 249 ± 66 s. The running time of ECMO was 7.8 ± 3.4 days. CONCLUSIONS: Enoxaparin anticoagulation appears to be feasible for VV ECMO patients without an increase in adverse events. Further larger-sampled and comparative studies are needed in the future to support our findings.

UNLABELLED: Direct oral anticoagulants from the perspective of Czech pharmacists - opinions, attitudes, confidence, and patient education during dispensing in a pharmacy Introduction and Aim: Pharmacists play an important role in the management of anticoagulation therapy, therefore good knowledge and confidence in care of patients treated with anticoagulation are essential. The aim of this study was to analyse the opinions and attitudes of pharmacists in the Czech Republic towards direct oral anticoagulants (DOACs), their perception of the benefits and risks of DOACs, and the position of pharmacists in educating patients about the basic principles of DOAC treatment in the context of dispensing these medicines in pharmacies. METHODS: An online anonymous questionnaire survey conducted in 2021 among pharmacists of three specific District Pharmacists Associations of the Czech Chamber of Pharmacy. The questionnaire included 32 open- and closed-ended questions, and questions for reporting of the level of agreement using a Likert scale. Descriptive statistics, parametric and non-parametric tests were used to evaluate the data. RESULTS: A total of 162 pharmacists participated (14% return rate), 139 of whom dispensed medicines in a pharmacy in the last year. Respondents working in pharmacies located in any health centre and in hospital pharmacies reported dispensing DOACs more frequently (p < 0.001). The majority of respondents (73%) felt completely or rather confident in providing expert information regarding DOACs. Higher confidence was associated with respondents working in hospital pharmacies or pharmacies located in health centres (p < 0.05), working in clinical pharmacy wards (p < 0.05) and being more likely to dispense DOACs in the pharmacy (p < 0.001). Higher confidence was related to the areas pharmacists discussed with patients during DOAC dispensing, e.g., reasons for using DOACs or how to administer. CONCLUSION: The frequency of dispensing DOACs, type of pharmacy, and working as clinical pharmacist influenced respondents' confidence towards DOACs. Confidence may have influenced the course of DOAC dispensing in the pharmacy. Consolidating the pharmacist's position in patient education during DOAC treatment and strengthening pharmacists' confidence in dispensing DOACs should be therefore considered.

BACKGROUND: Anticoagulation during extracorporeal membrane oxygenation (ECMO) might still lead to severe bleeding complications. Heparin is the most frequently used anticoagulant, but novel drugs could be promising. Argatroban is a new alternative to heparin. To date, no robust studies have confirmed the clear superiority of argatroban (AG) over heparin, although it has some advantages and may be safer. STUDY DESIGN AND METHODS: An observational study was conducted in all adult veno-venous ECMO patients with COVID-19-associated acute respiratory distress syndrome admitted to the University Hospital Ostrava (n = 63). They were anticoagulated with heparin in the first period and with AG in the second period, targeting the same activated partial thromboplastin time (aPTT; 45-60 s). Bleeding complications requiring transfusion and life-threatening bleeding events were evaluated. The primary objective was to compare heparin and AG in terms of bleeding, transfusion requirements and mortality-related bleeding. RESULTS: The total time on ECMO per patient was 16 days with an in-hospital mortality of 55.6%. The red blood cell consumption in the AG group (median 2.7 transfusions/week) was significantly lower than in the heparin group (median 4.2 transfusions/week, p = 0.011). Life-threatening bleeding complications were higher in the heparin group compared to the AG group (35.7% vs. 10.2%, p = 0.035), and mortality-related bleeding complications were also higher in the heparin group (21.4% vs. 2.0%, p = 0.032). DISCUSSION: Argatroban is an interesting alternative to heparin with less bleeding, less need for red blood cell transfusions and improved safety of ECMO with less mortality-related bleeding.

BACKGROUND: Abelacimab is a fully human monoclonal antibody that binds to the inactive form of factor XI and blocks its activation. The safety of abelacimab as compared with a direct oral anticoagulant in patients with atrial fibrillation is unknown. METHODS: Patients with atrial fibrillation and a moderate-to-high risk of stroke were randomly assigned, in a 1:1:1 ratio, to receive subcutaneous injection of abelacimab (150 mg or 90 mg once monthly) administered in a blinded fashion or oral rivaroxaban (20 mg once daily) administered in an open-label fashion. The primary end point was major or clinically relevant nonmajor bleeding. RESULTS: A total of 1287 patients underwent randomization; the median age was 74 years, and 44% were women. At 3 months, the median reduction in free factor XI levels with abelacimab at a dose of 150 mg was 99% (interquartile range, 98 to 99) and with abelacimab at a dose of 90 mg was 97% (interquartile range, 51 to 99). The trial was stopped early on the recommendation of the independent data monitoring committee because of a greater-than-anticipated reduction in bleeding events with abelacimab. The incidence rate of major or clinically relevant nonmajor bleeding was 3.2 events per 100 person-years with 150-mg abelacimab and 2.6 events per 100 person-years with 90-mg abelacimab, as compared with 8.4 events per 100 person-years with rivaroxaban (hazard ratio for 150-mg abelacimab vs. rivaroxaban, 0.38 [95% confidence interval {CI}, 0.24 to 0.60]; hazard ratio for 90-mg abelacimab vs. rivaroxaban, 0.31 [95% CI, 0.19 to 0.51]; P<0.001 for both comparisons). The incidence and severity of adverse events appeared to be similar in the three groups. CONCLUSIONS: Among patients with atrial fibrillation who were at moderate-to-high risk for stroke, treatment with abelacimab resulted in markedly lower levels of free factor XI and fewer bleeding events than treatment with rivaroxaban.

Proximal femur fractures (PFF) pose a major challenge in elderly patients with severe comorbidities and receiving antithrombotic therapy since according to the latest guidelines the surgery should be performed as soon as possible, preferably within 24 hours, to reduce mortality and morbidity. This review outlines the practical approach to surgical management of PFF that relies on increasing evidence of safety of early surgery in patients with PFF receiving antiplatelet and anticoagulant therapy. We have also used information from the existing evidence-based guidelines for elective/planned surgery in patients with antithrombotic therapy. The practical approach can be summarised as follows: • Antiplatelet therapy - discontinuation of acetylsalicylic acid (ASA) and clopidogrel in monotherapy or in combination is not necessary prior to surgery. In case of bleeding, antifibrinolytic therapy is recommended as well as administration of platelet concentrate which is rarely needed. • In patients taking warfarin, reversal of its effects is recommended by early administration of vitamin K to allow surgery to be performed within 24 hours. Prothrombin complex concentrate (PCC) as a second-line drug is reserved for extreme cases only. Warfarin therapy is resumed 24 hours after surgery. • Direct oral anticoagulants must be discontinued 24-48 hours prior to surgery, possibly longer depending on the type of drug, time of administration of the last dose, and renal function. In extreme cases, an antidote (idarucizumab, off-label andexanet) can be administered prior to surgery, or PCC in case they are unavailable. Anticoagulation therapy is resumed in 24-48 hours. • Neuraxial anaesthesia is possible when ASA is taken by the patient and in case of effective warfarin reversal. • In early surgery and rapid restart of anticoagulant therapy, bridging therapy with LMWH is not indicated except for in cases with extreme risk of thrombosis. Key words: proximal femur fracture, antiplatelet therapy, anticoagulant therapy, perioperative management.

BACKGROUND: Maintaining the patient awake and not intubated during the venovenous extracorporeal membrane oxygenation (VV ECMO) reduces the risk of ventilation-induced lung injury in patients with ARDS. Currently, there is a lack of data on outcomes and complications associated with the awake ECMO approach. OBJECTIVES: To evaluate outcomes and the occurrence of complications of awake ECMO approach guided by local safety protocol comprising ultrasound-guided cannulation, argatroban-based anticoagulation, respiratory support, and routine sedation targeted to reduce respiratory effort and keeping nurse-to-patient ratio of 1:1. DESIGN: A single-center retrospective case series analysis. METHODS: Consecutive patients with COVID-19-related acute respiratory distress syndrome (ARDS) (CARDS) treated by full awake VV ECMO approach from April 2019 to December 2023 were eligible. RESULTS: Our center treated 10 patients (mean age 54.7 ± 11.6 years) with CARDS with an awake ECMO approach. The reasons for awake ECMO included the presence of barotrauma in six patients, a team consensus to prefer awake ECMO instead of mechanical ventilation in three patients, and the patient's refusal to be intubated in one case. Before ECMO, patients were severely hypoxemic, with a mean value of Horowitz index of 48.9 ± 9.1 mmHg and a mean respiratory rate of 28.8 ± 7.3 breaths per minute on high-flow nasal cannula or noninvasive ventilation support. The mean duration of awake VV ECMO was 558.0 ± 173.6 h. Seven patients (70%) were successfully disconnected from ECMO and fully recovered. Intubation from respiratory causes was needed in three patients (30%), all of whom died eventually. In total, three episodes of delirium, two episodes of significant bleeding, one pneumothorax requiring chest tube insertion, and one oxygenator acute exchange occurred throughout the 5580 h of awake ECMO. No complications related to cannula displacement or malposition occurred. CONCLUSION: The awake ECMO strategy guided by safety protocol appears to be a safe approach in conscious, severely hypoxemic, non-intubated patients with COVID-19-related ARDS.

Enhancing the safety and effectiveness of extracorporeal membrane oxygenation (ECMO) therapy in awake, spontaneously breathing patients with the most severe form of COVID-19-related acute respiratory distress syndrome (ARDS)Why Was the Study Done? Extracorporeal membrane oxygenation (ECMO) represents a life-saving therapeutic approach that ensures appropriate gas exchange in patients with the most severe form of respiratory failure – acute respiratory distress syndrome (ARDS). Typically, patients are connected to ECMO when already deeply sedated and mechanically ventilated. The awake ECMO approach (keeping the patient awake, not intubated, and breathing spontaneously during ECMO support) minimizes the risks associated with mechanical ventilation and provides several relevant physiological benefits. However, the awake ECMO approach is also associated with several significant risks, including delirium, bleeding, and cannula displacement. Published papers have reported relatively frequent complications and method failures. What Did the Researchers Do? To address safety concerns regarding the awake ECMO approach, we present a single-center retrospective analysis of ten COVID-19-related ARDS patients treated with the awake ECMO approach, guided by the local safety protocol. What Did the Researchers Find? The awake ECMO approach yielded success (i.e., the patient was not intubated for respiratory causes, was successfully disconnected from ECMO, and fully recovered in seven patients (70.0%), outperforming previously published efficacy ranges. Three patients were intubated due to the progression of respiratory failure and eventually died. The incidence of adverse events during the 5,580 hours of awake ECMO was considered low. No cannula displacement or malposition occurred despite routine active physiotherapy, including walking during ECMO treatment in three patients. What Do the Findings Mean? The general applicability of the study is limited by the low number of patients and the retrospective monocentric design. However, the presented data illustrate real-life clinical scenarios and could aid clinicians in managing severely hypoxemic but still conscious and cooperative patients.

BACKGROUND: Short and rare episodes of atrial fibrillation (AF) are commonly detected using implanted devices (device-detected AF) in patients with prior stroke or transient ischemic attack (TIA). The effectiveness and safety of oral anticoagulation in patients with prior stroke or TIA and device-detected AF but with no ECG-documented AF is unclear. METHODS AND RESULTS: This prespecified analysis of the NOAH-AFNET 6 (Non-Vitamin K Antagonist Oral Anticoagulants in Patients With Atrial High Rate Episodes) trial with post hoc elements assessed the effect of oral anticoagulation in patients with device-detected AF with and without a prior stroke or TIA in the randomized, double-blind, double-dummy NOAH-AFNET 6 trial. Outcomes were stroke, systemic embolism, and cardiovascular death (primary outcome) and major bleeding and death (safety outcome). A prior stroke or TIA was found in 253 patients with device-detected AF randomized in the NOAH-AFNET 6 (mean age, 78 years; 36.4% women). There was no treatment interaction with prior stroke or TIA for any of the primary and secondary time-to-event outcomes. In patients with a prior stroke or TIA, 14 out of 122 patients experienced a primary outcome event with anticoagulation (5.7% per patient-year). Without anticoagulation, there were 16 out of 131 patients with an event (6.3% per patient-year). The rate of stroke was lower than expected (anticoagulation: 4 out of 122 [1.6% per patient-year]; no anticoagulation: 6 out of 131 [2.3% per patient-year]). Numerically, there were more major bleeding events with anticoagulation in patients with prior stroke or TIA (8 out of 122 patients) than without anticoagulation (2 out of 131 patients). CONCLUSIONS: Anticoagulation appears to have ambiguous effects in patients with device-detected AF and a prior stroke or TIA in this hypothesis-generating analysis of the NOAH-AFNET 6 in the absence of ECG-documented AF, partially due to a low rate of stroke without anticoagulation.

AIMS: Screening logs have the potential to appraise the actual prevalence and distribution of predefined patient subsets, avoiding selection biases, which are inevitably and potentially present in randomised trials and real-world registries, respectively. We aimed to assess the prevalence of high bleeding risk (HBR) characteristics in the real world and the external validity of the MASTER DAPT trial. METHODS AND RESULTS: All consecutive patients who underwent percutaneous coronary intervention (PCI) for at least two consecutive weeks across 65 sites participating in the trial were entered into a screening log. Of 2,847 consecutive patients, 1,098 (38.6 %) were HBR and 109 (9.9 %) consented for trial participation. PRECISE-DAPT score ≥ 25 was the most frequent HBR feature, followed by advanced age, use of oral anticoagulation (OAC) and anaemia. Compared with consecutive HBR patients, consenting patients were older (≥ 75 years: 69 % versus 62 %, absolute standardized difference [SD] 0.16), more frequently male (78 % versus 71 %, absolute SD 0.18), had higher use of OAC (38 % versus 20 %, absolute SD 0.39), treatment with steroids or nonsteroidal anti-inflammatory drugs (10 % versus 5 %, SD 0.16), and prior cerebrovascular events (10 % versus 6 %, absolute SD 0.18) but lower PRECISE DAPT score ≥ 25 (54 % versus 66 %, absolute SD 0.24). CONCLUSIONS: The HBR criteria distribution differed between consecutive versus selectively included HBR patients, suggesting the existence of selection biases in the trial population.
