RESUMEN
OBJECTIVE: To estimate the prevalence of inappropriate use of prophylaxis to prevent venous thromboembolism (VTE) in patients with medical diseases admitted to hospital from the emergency department. To explore variables associated with inappropriate thromboprophylaxis. METHODS: Prospective multicenter cohort study in 15 hospital emergency departments. We included patients admitted for a medical condition during 7 days in the first quarter of 2022. We assessed risk for VTE with the Padua Prediction Score (PPS). Inappropriate thromboprophylaxis was defined by failure to prescribe prophylaxis in patients with a high-risk PPS assessment unless there were absolute contraindications (active bleeding or severe thrombopenia) or, alternatively, the prescription of prophylaxis in patients with a low-risk PPS assessment or absolute contraindications. A logistic regression model was adjusted for risk level to identify variables associated with inappropriate use of thromboprophylaxis. RESULTS: Of a total of 630 patients included, 450 (71.4%) had PPS scores indicating high risk for VTE; 180 patients were at low risk. Thromboprophylaxis was inappropriate in 248 patients (39.4%): 165 high-risk patients who received no prophylaxis, 82 low-risk patients who were nonetheless treated, and 1 patient who was treated in spite of severe thrombopenia. Odds ratios (ORs) revealed that the variables associated with inappropriate use of thromboprophylaxis were trauma or recent surgery (OR, 5.53; 95% CI, 1.58-19.34), presence of factors indicating risk for bleeding (OR, 2.61; 95% CI, 1.44-4.73), and hospital admission for either urinary tract infection (OR, 2.29; 95% CI, 1.07-4.87) or gastrointestinal disease (OR, 4.30; 95% CI, 1.71-10.85). CONCLUSIONS: The inappropriate use of thromboprophylaxis in Spanish emergency departments is high and associated with certain clinical characteristics.
OBJETIVO: Evaluar la inadecuación de la tromboprofilaxis farmacológica, según la escala Padua (PPS), para prevenir la enfermedad tromboembólica venosa (ETV) entre los pacientes que ingresan desde el servicio de urgencias hospitalario (SUH) por patología médica, así como las variables asociadas a su uso inadecuado. METODO: Estudio de cohortes, prospectivo, multicéntrico donde participaron 15 SUH. Se incluyeron los pacientes atendidos que requirieron ingreso por enfermedad médica durante 7 días del primer trimestre de 2022. La inadecuación de la tromboprofilaxis farmacológica se definió como la no utilización en pacientes clasificados por PPS de alto riesgo sin contraindicaciones absolutas para su uso (hemorragia activa o trombopenia grave) o su utilización en pacientes de riesgo bajo o con contraindicaciones absolutas. Se ajustó, para cada grupo de riesgo, un modelo de regresión logística para identificar las variables asociadas a la inadecuación. RESULTADOS: Se incluyeron 630 pacientes, 450 (71,4%) tenían riesgo alto y 180 (28,6%) riesgo bajo para ETV según la PPS. De ellos, la tromboprofilaxis fue inadecuada en 248 pacientes (39,4%) (165 tenían riesgo alto pero no recibieron tromboprofilaxis, 1 la recibió teniendo trombopenia grave y 82 tenían riesgo bajo pero recibieron tromboprofilaxis). Las variables asociadas con la inadecuación en pacientes de alto riesgo fueron trauma o cirugía recientes con odds ratio (OR) de OR 5,53 (IC 95%: 1,58-19,34), presencia de factores de riesgo hemorrágico con OR de 2,61 (IC 95%: 1,44-4,73), e infección del tracto urinario con OR de 2,29 (IC 95%: 1,07-4,87) y enfermedad gastrointestinal con OR de 4,30 (IC 95%: 1,71-10,85) como motivos de ingreso. CONCLUSIONES: En los SUH españoles, el uso inadecuado de la tromboprofilaxis farmacológica es elevado. Algunas características clínicas se asocian al uso inadecuado de dicha tromboprofilaxis.

BACKGROUND: The purpose of the study is to examine if prolonged thromboprophylaxis decreases the risk of thrombosis after intended curative surgery for oesophageal cancer. Study results are expected to inform a guideline for thromboprophylaxis after oesophageal cancer surgery. The perspective is to reduce morbidity and mortality in this critically ill patient group. Thrombosis is the second-most common cause of cancer death after the cancer itself. The risk of thrombosis depends on the cancer type, and upper gastrointestinal cancers are considered high risk. This risk is further increased when patients undergo surgery. However, only few studies have investigated the peri- and postoperative coagulation profile in oesophageal cancer patients. Due to this lack of knowledge, prophylaxis is currently restricted to 5000 IU (international units) low-molecular weight heparin daily from surgery until discharge from hospital (approximately 10 days), whereas patients with gastric cancer receive 30 days of treatment. The present study examines whether a 30-day treatment is superior and safe, compared with the current standard treatment. METHODS: The study is a randomised controlled trial. Inclusion is ongoing, and we aim to include 100 patients. Blood samples are drawn before and after surgery, and the coagulation is extensively examined. The primary endpoint is the difference in plasma levels of prothrombin fragment 1 + 2 (F1 + 2) 30 days after surgery between the intervention and the standard group. Furthermore, patients are examined with ultrasound to screen for asymptomatic venous thrombotic events (VTE). Secondary endpoints are incidence of bleeding, symptomatic and asymptomatic VTE and mortality 30 days 1 one year after surgery. DISCUSSION: The study will provide valuable information on the perioperative coagulation profile and VTE risk of oesophageal cancer patients. The study seeks to aid in optimising the postoperative thromboprophylaxis, and the perspective is to reduce morbidity and mortality in this at-risk patient population. TRIALS REGISTRATION: The trial was prospectively registered at the EU Clinical Trials Register with ID 2021-001335-24 on 30 June 2021 and at ClinicalTrials.gov with study identifier NCT05067153.

Objective: To assess doctors' knowledge, attitudes and practices regarding venous thromboembolism prophylaxis. METHODS: The cross-sectional study was conducted from April to September 2021 in three public-sector hospitals affiliated with the Rawalpindi Medical University: Holy Family Hospital, Benazir Bhutto Hospital and Rawalpindi District Headquarters Hospital, Rawalpindi, Pakistan, and comprised physicians of either gender who were actively involved in patient care. Data was collected using a predesigned questionnaire regarding venous thromboembolism. Data was analysed using SPSS 25. RESULTS: All the 220(100%) subjects approached responded positively to the study questionnaire. There were 144(65.45%) general surgeons, 50(22.72%) gynaecologists and 26(11.81%) orthopaedic surgeons. Overall, there were 26(11.81%) senior consultants, 65(29.54%) postgraduate residents and 129(58.63%) house officers. There were 150(68.2%) doctors who reported having witnessed deep-vein thrombosis in their patients, and 113(51.4%) had witnessed deaths related to pulmonary embolism. Among the methods employed for DVT diagnosis, the use of clinical criteria was the most common 136(36.1%), while venography was the least common technique used by 8(2.2%). While 210(95.5%) subjects expressed the desire for adopting an institute-wide regimen for venous thromboembolism prophylaxis, only 66(30%) were currently following such a regimen.

BACKGROUND: Direct oral anticoagulants (DOACs) have complex dosing regimens and are often incorrectly prescribed. We evaluated a nationwide DOAC population management dashboard rollout whose purpose includes pharmacist review and correction of off-label dosing prescriptions. METHODS AND RESULTS: Using data from Veterans Health Affairs, we identified all patients prescribed DOACs for atrial fibrillation or venous thromboembolism between August 2015 and December 2019. Sites were grouped on the basis of the timing of moderate-high usage of the DOAC population management tool dashboard. Effectiveness was defined as the monthly rate of off-label DOAC prescribing and the rate of clinical adverse events (bleeding, composite of stroke or venous thromboembolism). Implementation was evaluated as the percentage of off-label DOAC prescriptions changed within 7 days. Among the 128 652 patients receiving DOAC therapy at 123 centers, between 6.9% and 8.6% had off-label DOAC prescriptions. Adoption of the DOAC population management tool dashboard before July 2018 was associated with a decline in off-label dosing prescriptions (8.7%-7.6%). Only 1 group demonstrated a significant reduction in monthly rates of bleeding following implementation. All sites experienced a reduction in the composite of venous thromboembolism or stroke following dashboard adoption. There was no difference in the implementation outcome of DOAC prescription change within 7 days in any of the adoption groups. CONCLUSIONS: Early adoption of the DOAC population management tool dashboard was associated with decreased rates of off-label DOAC dosing prescription and reduced bleeding. Following adoption of the DOAC population management tool dashboard, all sites experienced reductions in venous thromboembolism and stroke events.

Superficial vein thrombosis (SVT), a manifestation of venous thromboembolism (VTE), is a common condition, yet of all the types of VTE, it has been the least well studied. Recent studies have challenged the conception that SVT is a benign disease, showing that its risk factors overlap with those of deep-vein thrombosis (DVT) and that it is frequently associated with DVT or pulmonary embolism (PE). In 2010, the CALISTO trial demonstrated the benefit of treatment with fondaparinux at the dose of 2.5mg (one injection per day) for 45days for lower limb SVT. Prior to CALISTO, the treatment of SVT was based on venous compression therapy, nonsteroidal anti-inflammatory drugs (NSAID) and anticoagulation using various therapeutic regimens. Surgery could also be envisaged in certain cases. In CALISTO, the inclusion criteria designed to obtain a homogeneous population meant that numerous questions remained unanswered with respect to SVT occurring in other locations and under other circumstances, notably in pregnant women, patients with renal insufficiency, and patients with recurrent SVT or superficial vein thrombosis less than 5cm long. The aim of this section is to review the current state of knowledge of SVT and to propose or recommend therapeutic strategies for the management of SVT according to the clinical context, the location of the thrombosis, and the presence of particular risk factors.

Obesity is an alarming worldwide public health issue and is defined as a body mass index (BMI) of 30kg/m2 or more. It is considered as a risk factor for first thrombotic event and is associated with a significant risk of recurrence. Consequently, obese patients are often treated by anticoagulant therapy but data from randomised control trial are scarce. We will review in this narrative review the state of the art of the prescription of anticoagulant for the prevention and treatment of venous thromboembolism (VTE) in obese patients.

Background: Venous thromboembolism (VTE) poses a significant global health challenge, notably exacerbated by the use of combined oral contraceptives (COCs). Evidence mainly focuses on the type of progestogen used in COCs to establish the increased risk of VTE with less data assessed on the type of estrogen used. This meta-analysis aims to assess the risk of VTE associated with COCs containing synthetic estrogens like ethinylestradiol (EE) versus natural estrogens like estradiol (E2). Methods: A systematic review and meta-analysis was conducted following the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Literature searches were performed in December 2023 in MEDLINE and EMBASE to identify clinical studies comparing the VTE risk between COCs containing synthetic versus natural estrogens. Studies were selected through rigorous screening, and data extraction followed standardized protocols, with statistical analyses employing a random effects model. Results: The search yielded five relevant studies, involving over 560,000 women/time, demonstrating a significant 33% reduction in VTE risk among users of natural estrogen-based COCs compared to synthetic estrogen-based COCs (OR 0.67, 95% CI 0.51-0.87). Stratification analyses using adjusted hazard ratios (HR) of the main observationnal studies showed a 49% reduced VTE risk of E2-based pills compared to EE in association with levonorgestrel. Discussion and conclusion: Despite the longstanding use of EE-based COCs, emerging evidence supports a lower thrombotic risk associated with natural estrogens. This meta-analysis substantiates the lower VTE risk associated with natural estrogen-based COCs compared to synthetic alternatives, advocating for a re-evaluation of contraceptive guidelines to prioritize patient safety and reduce thrombotic risks.

BACKGROUND: Use of extended pharmacologic thromboprophylaxis after major abdominopelvic cancer surgery should depend on best-available scientific evidence and patients' informed preferences. We developed a risk-stratified patient decision aid to facilitate shared decision-making and sought to evaluate its effect on decision-making quality regarding use of extended thromboprophylaxis. METHODS: We enrolled patients undergoing major abdominopelvic cancer surgery at an academic tertiary care centre in this pre-post study. We evaluated change in decisional conflict, readiness to decide, decision-making confidence, and change in patient knowledge. Participants were provided the appropriate risk-stratified decision aid (according to their Caprini score) in either the preoperative or postoperative setting. A sample size calculation determined that we required 17 patients to demonstrate whether the decision aid meaningfully reduced decisional conflict. We used the Wilcoxon matched-pairs signed ranks test for interval scaled measures. RESULTS: We included 17 participants. The decision aid significantly reduced decisional conflict (median decisional conflict score 2.37 [range 1.00-3.81] v. 1.3 [range 1.00-3.25], p < 0.01). With the decision aid, participants had high confidence (median 86.4 [range 15.91-100]) and felt highly prepared to make a decision (median 90 [range 55-100]). Median knowledge scores increased from 50% (range 0%-100%) to 75% (range 25%-100%). CONCLUSION: Our risk-stratified, evidence-based decision aid on extended thromboprophylaxis after major abdominopelvic surgery significantly improved decision-making quality. Further research is needed to evaluate the usability and feasibility of this decision aid in the perioperative setting.

Thrombotic manifestations, mainly venous thromboembolism (VTE) and stroke, are the most common and potentially life-threatening presentations of antiphospholipid syndrome (APS). The management of APS requires the assessment of the antiphospholipid antibodies (aPL) profile, of concurrent systemic lupus erythematosus or other systemic autoimmune diseases and the presence of risk factors for cardiovascular disease and bleeding. Anticoagulation with vitamin K antagonists (VKA) remains the cornerstone of therapy for thrombotic APS. As platelets play a central role in APS, low-dose aspirin is the first option for primary thromboprophylaxis in asymptomatic aPL carriers, and also plays a role as combination therapy with VKAs in arterial thrombosis. Treatment with direct oral anticoagulants (DOACs) could be considered in certain low-risk situations, although they are not recommended in patients with arterial thrombosis or triple positive aPL. Adjuvant therapies such as hydroxychloroquine and statins may be useful in complex settings such as thrombotic recurrences or high risk of bleeding. In this article, we review the evidence and the recommendations of the guidelines for the treatment of APS, and provide a critical and practical approach of its management from our clinical perspective.

BACKGROUND: Venous thromboembolism (VTE) is a preventable medical condition which has substantial impact on patient morbidity, mortality, and disability. Unfortunately, adherence to the published best practices for VTE prevention, based on patient centered outcomes research (PCOR), is highly variable across U.S. hospitals, which represents a gap between current evidence and clinical practice leading to adverse patient outcomes. This gap is especially large in the case of traumatic brain injury (TBI), where reluctance to initiate VTE prevention due to concerns for potentially increasing the rates of intracranial bleeding drives poor rates of VTE prophylaxis. This is despite research which has shown early initiation of VTE prophylaxis to be safe in TBI without increased risk of delayed neurosurgical intervention or death. Clinical decision support (CDS) is an indispensable solution to close this practice gap; however, design and implementation barriers hinder CDS adoption and successful scaling across health systems. Clinical practice guidelines (CPGs) informed by PCOR evidence can be deployed using CDS systems to improve the evidence to practice gap. In the Scaling AcceptabLE cDs (SCALED) study, we will implement a VTE prevention CPG within an interoperable CDS system and evaluate both CPG effectiveness (improved clinical outcomes) and CDS implementation. METHODS: The SCALED trial is a hybrid type 2 randomized stepped wedge effectiveness-implementation trial to scale the CDS across 4 heterogeneous healthcare systems. Trial outcomes will be assessed using the RE2-AIM planning and evaluation framework. Efforts will be made to ensure implementation consistency. Nonetheless, it is expected that CDS adoption will vary across each site. To assess these differences, we will evaluate implementation processes across trial sites using the Exploration, Preparation, Implementation, and Sustainment (EPIS) implementation framework (a determinant framework) using mixed-methods. Finally, it is critical that PCOR CPGs are maintained as evidence evolves. To date, an accepted process for evidence maintenance does not exist. We will pilot a "Living Guideline" process model for the VTE prevention CDS system. DISCUSSION: The stepped wedge hybrid type 2 trial will provide evidence regarding the effectiveness of CDS based on the Berne-Norwood criteria for VTE prevention in patients with TBI. Additionally, it will provide evidence regarding a successful strategy to scale interoperable CDS systems across U.S. healthcare systems, advancing both the fields of implementation science and health informatics.

PURPOSE: Radical cystectomy is associated with bleeding and high transfusion rates, presenting challenges in patient management. This study investigated the prophylactic use of tranexamic acid during radical cystectomy. METHODS: All consecutive patients treated with radical cystectomy at a tertiary care university center were included from a prospectively maintained database. After an institutional change in the cystectomy protocol patients received 1 g of intravenous bolus of tranexamic acid as prophylaxis. To prevent bias, propensity score matching was applied, accounting for differences in preoperative hemoglobin, neoadjuvant chemotherapy, tumor stage, and surgeon experience. Key outcomes included transfusion rates, complications, and occurrence of venous thromboembolism. RESULTS: In total, 420 patients were included in the analysis, of whom 35 received tranexamic acid. After propensity score matching, 32 patients and 32 controls were matched with regard to clinicopathologic characteristics. Tranexamic acid significantly reduced the number of patients who received transfusions compared to controls (19% [95%-Confidence interval = 8.3; 37.1] vs. 47% [29.8; 64.8]; p = 0.033). Intraoperative and postoperative transfusion rates were lower with tranexamic acid, though not statistically significant (6% [1.5; 23.2] vs. 19% [8.3; 37.1], and 16% [6.3; 33.7] vs. 38% [21.9; 56.1]; p = 0.257 and p = 0.089, respectively). The occurrence of venous thromboembolism did not differ significantly between the groups (9% [2.9; 26.7] vs. 3% [0.4; 20.9]; p = 0.606). CONCLUSION: Prophylactic tranexamic administration, using a simplified preoperative dosing regimen of 1 g as a bolus, significantly lowered the rate of blood transfusion after cystectomy. This exploratory study indicates the potential of tranexamic acid in enhancing outcomes of open radical cystectomy.

INTRODUCTION: Sequential compression devices (SCDs) are the mainstay of mechanical prophylaxis for venous thromboembolism in perioperative neurosurgical patients and are especially crucial when chemical prophylaxis is contraindicated. OBJECTIVES: This study aimed to characterise and improve SCD compliance in neurosurgery stepdown patients. METHODS: SCD compliance in a neurosurgical stepdown unit was tracked across 13 months (August 2022-August 2023). When not properly functioning, the missing element was documented. Compliance was calculated daily in all patients with SCD orders, and then averaged monthly. Most common barriers to compliance were identified. With nursing, we implemented a best practice alert to facilitate nursing education at month 3 and tracked compliance over 9 months, with two breaks in surveillance. At month 12, we implemented a patient-engagement measure through creating and distributing a patient-directed infographic and tracked compliance over 2 months. RESULTS: Compliance averaged 19.7% (n=95) during August and 38.4% (n=131) in September. After implementing the best practice alert and supply chain upgrades, compliance improved to 48.8% (n=150) in October, 41.2% (n=104) in March and 45.9% (n=76) in April. The infographic improved compliance to 51.4% (n=70) in July and 55.1% (n=34) in August. Compliance was significantly increased from baseline in August to October (z=4.5838, p<0.00001), sustained through March (z=3.2774, p=0.00104) and further improved by August (z=3.9025, p=0.0001). CONCLUSION: Beyond an initial Hawthorne effect, implementation of the best practice nursing alert facilitated sustained improvement in SCD compliance despite breaks in surveillance. SCD compliance nonetheless remained below 50% until implementation of patient-engagement measures which were dependent on physician involvement.

INTRODUCTION: Venous thromboembolism (VTE) is a major concern following total knee arthroplasty (TKA). The optimal pharmacological prophylaxis remains, however, controversial. The present investigation compared several non-vitamin K antagonist oral anticoagulants commonly employed as VTE prophylaxis following TKA. A Bayesian network meta-analysis was conducted to compare apixaban, aspirin, dabigatran, edoxaban, enoxaparin, fondaparinux, and rivaroxaban. The outcomes of interest were to compare the rate of deep venous thrombosis (DVT), pulmonary embolism (PE), and major and minor haemorrhages. METHODS: This study was conducted according to the PRISMA Extension Statement for Reporting of Systematic Reviews Incorporating Network Meta-Analyses of Health Care Interventions. In March 2024, PubMed, Web of Science, and Google Scholar were accessed with no time constraints. All randomised controlled trials (RCTs) comparing two or more drugs for the prevention of VTE following TKA were considered for inclusion. RESULTS: Data from 29,678 patients were collected. Of them, 67% (19,884 of 29,678 patients) were women. The mean age of the patients was 66.8 ± 2.8 years, and the mean BMI was 29.2 ± 1.5 kg/m2. There was comparability in age, sex, and BMI at baseline. Apixaban 5 mg, dabigatran 220 mg, and rivaroxaban 10 mg were the most effective in reducing the rate of DVT. Apixaban 5 mg, enoxaparin 60 mg, and rivaroxaban 40 mg were the most effective in reducing the rate of PE. Apixaban 5 mg, rivaroxaban 10 mg, and apixaban 10 mg were associated with the lowest rate of major haemorrhages. Apixaban 5 mg and 20 mg, and dabigatran 220 mg were associated with the lowest rate of minor haemorrhages. CONCLUSION: Administration of apixaban 5 mg demonstrated the best balance between VTE prevention and haemorrhage control following TKA. LEVEL OF EVIDENCE: Level I, network meta-analysis of RCTs.

BACKGROUND: The risk of venous thromboembolism (VTE) is 15 to 35-fold higher in the postpartum period compared to non-pregnant individuals. Clinical practice guidelines recommend the use of postpartum thromboprophylaxis with low molecular weight heparin (LMWH) for 6 weeks in individuals at high risk of developing VTE. However, a marked reduction in the risk of VTE risk occurs beyond the third week of the postpartum period. OBJECTIVE: We sought to characterize practice patterns of clinicians who manage postpartum individuals at high risk of VTE. METHODS: We conducted a cross-sectional study using a self-administered electronic questionnaire. The survey explored the use of postpartum thromboprophylaxis in high-risk individuals. Descriptive statistics were used to summarize survey responses. RESULTS: Of the 113 participants that responded to the initial invitation, 78 completed the survey (Europe (53.9 %); North America (23.2 %); Australia and New Zealand (19.0 %)). For individuals with a prior unprovoked or provoked deep venous thrombosis or pulmonary embolism, cerebral vein thrombosis and splanchnic vein thrombosis, 97.4 %, 93.5 %, 91.0 % and 88.5 % of the respondents recommended six weeks of postpartum thromboprophylaxis using LMWH, respectively. The recommendation for 6 weeks of thromboprophylaxis in patients with sickle cell disease and obstetric APS was comparatively lower (70.5 and 78.2 % respectively). Respondents with higher practice volumes and more years of experience in clinical practice were more likely to recommend a shorter duration of thromboprophylaxis. CONCLUSION: Our study highlights the variability in clinician recommendations and the acceptability of treatment durations for postpartum thromboprophylaxis in high-risk conditions. Prospective studies are needed to determine optimal duration and establish evidence-based management.

Background: Current literature demonstrates prophylactic enoxaparin to be efficacious in reducing venous thromboembolism (VTE) rates without significantly increasing risk for bleeding complications. Despite this evidence, prophylactic enoxaparin doses are frequently withheld for surgery or procedures. This exploratory study aims to quantify the risk of a VTE event in trauma patients associated with missed doses of prophylactic enoxaparin. Methods: This retrospective cohort study evaluated trauma patients admitted to our Level 1 trauma center from January 1, 2012 to January 31, 2021. A 1:1 propensity match with ten variables was performed to compare patients receiving prophylactic enoxaparin that had a VTE and those that did not. The primary outcome was a VTE event. Results: 493 patients met inclusion criteria; 1:1 propensity score matching was performed resulting in a cohort of 184 patients. The percentage of patients that missed a prophylactic enoxaparin dose in the VTE group was higher than the no VTE group (34.8% vs 21.7%, P = 0.049). This is consistent when examining total missed doses (P = 0.038) and consecutively missed doses (P = 0.035). The odds of having a VTE for patients that missed at least one dose or more of enoxaparin are nearly two times greater (OR 1.92, 95% CI 0.997, 3.7). Conclusion: Missing enoxaparin doses significantly increases the risk of VTE in matched populations. Most prophylactic enoxaparin doses were held for procedures, and not for bleeding events. Trauma teams should carefully weigh the risk of bleeding complications associated with continuing enoxaparin prophylaxis against the significant thromboembolic risk of withholding it.

BACKGROUND: Based on the Khorana score, guidelines recommend anticoagulation for primary prophylaxis (PP) in outpatients with cancer with an intermediate-to-high risk of venous thromboembolism (VTE). ONKOTEV score has been prospectively externally validated as novel risk assessment model (RAM) with good discriminatory performances but no direct comparisons with Khorana Score are available. METHODS: Using the ONKOTEV validation dataset (n = 425), we applied generalized decision curve analysis (gDCA) which integrates the principles of evidence-based medicine with treatment effects, model accuracy and patient preferences (weighted as the relative value [RV] of avoiding VTE versus major bleeding [MB]). The aim is to select the most optimal treatment strategy among multiple options: "no treatment", "treat all patients with DOAC/LMVH", or "use ONKOTEV/KHORANA scores to guide PP with DOAC/LMWH". RESULTS: Results showed that ONKOTEV-guided PP (using DOAC or LMWH) remained the most optimal strategy for wide range assumption of treatment efficacy and patient's preference. For those patients, who value avoiding VTE more than MB, then offering DOAC to all patients represents the best strategy. When MBs are feared more than the morbidity of VTE, ONKOTEV-guided PP (DOAC) represents the best management strategy. In all cases, ONKOTEV outperformed Khorana for individualized VTE prevention. CONCLUSIONS: When the two predictive models are integrated within a decision analysis framework, ONKOTEV appears superior to Khorana Score in guiding individualized prevention of cancer-related VTE in outpatients with cancer. The findings herein reported provide cutting edge insights in cancer care and support the spread of ONKOTEV score in the ambulatory cancer setting.

Aims: We investigated the efficacy and safety profile of commonly used venous thromboembolism (VTE) prophylaxis agents following hip and knee arthroplasty. Methods: A systematic search of PubMed, Embase, Cochrane Library, Web of Science, and OrthoSearch was performed. Prophylaxis agents investigated were aspirin (< 325 mg and ≥ 325 mg daily), enoxaparin, dalteparin, fondaparinux, unfractionated heparin, warfarin, rivaroxaban, apixaban, and dabigatran. The primary efficacy outcome of interest was the risk of VTE, whereas the primary safety outcomes of interest were the risk of major bleeding events (MBE) and wound complications (WC). VTE was defined as the confirmed diagnosis of any deep vein thrombosis and/or pulmonary embolism. Network meta-analysis combining direct and indirect evidence was performed. Cluster rank analysis using the surface under cumulative ranking (SUCRA) was applied to compare each intervention group, weighing safety and efficacy outcomes. Results: Of 86 studies eligible studies, cluster rank analysis showed that aspirin < 325 mg daily (SUCRA-VTE 89.3%; SUCRA-MBE 75.3%; SUCRA-WC 71.1%), enoxaparin (SUCRA-VTE 55.7%; SUCRA-MBE 49.8%; SUCRA-WC 45.2%), and dabigatran (SUCRA-VTE 44.9%; SUCRA-MBE 52.0%; SUCRA-WC 41.9%) have an overall satisfactory efficacy and safety profile. Conclusion: We recommend the use of either aspirin < 325 mg daily, enoxaparin, or dabigatran for VTE prophylaxis following hip and knee arthroplasty.

BACKGROUND: Limited real-world evidence is available comparing the safety and effectiveness of apixaban and low-molecular-weight heparins (LMWHs) for preventing recurrent venous thromboembolism (VTE) in patients with active cancer receiving anticoagulation in an extended treatment setting. This study evaluated the risk of bleeding and recurrent VTE in patients with cancer-associated VTE who were prescribed apixaban or LMWH for ≥3 months. METHODS: A US commercial claims database was used to identify adult patients with VTE and active cancer who initiated apixaban or LMWH 30 days following the first VTE diagnosis and had ≥3 months of continuous enrollment and 3 months of primary anticoagulation treatment. Patients were followed from the day after the end of primary anticoagulation treatment until the earliest of: date of disenrollment, discontinuation of index anticoagulant, switch to another anticoagulant, or end of the study period. Inverse-probability treatment weighting (IPTW) was used to balance treatment cohorts. Incidence rates (IRs) for the outcomes were calculated per 100 person-years (PY). Cox proportional hazard models were used to evaluate the adjusted risk of recurrent VTE, major bleeding (MB), and clinically relevant nonmajor bleeding (CRNMB). RESULTS: A total of 13,564 apixaban- and 2,808 LMWH-treated patients were analyzed. Post-IPTW, the treatment cohorts were balanced. Patients receiving apixaban had lower adjusted IRs for recurrent VTE (4.1 vs 9.6 per 100 PY), MB (6.3 vs 12.6), and CRNMB (26.1 vs 36.0) versus LMWH (P<.0001 for all comparisons) during the follow-up period. Patients on apixaban had a lower adjusted risk of recurrent VTE (hazard ratio [HR], 0.42; 95% CI, 0.34-0.53), MB (HR, 0.50; 95% CI, 0.41-0.61), and CRNMB (HR, 0.76; 95% CI, 0.68-0.85) versus LMWH. CONCLUSIONS: Extended anticoagulation treatment of ≥3 months with apixaban was associated with lower rates of recurrent VTE, MB, and CRNMB compared with LMWH in adults with cancer-associated VTE.
