Background: Venous thromboembolism (VTE) is a major cause of perioperative morbimortality. Despite significant efforts to advance evidence-based practice, prevention rates remain inadequate in many centres.
Objective: To evaluate the effectiveness of different strategies aimed at improving adherence to adequate VTE prophylaxis in surgical patients at high risk of VTE.
Method: Before and after intervention study conducted at a tertiary hospital. Adherence to adequate VTE prophylaxis was compared according to three strategies consecutively implemented from January 2019 to December 2020. A dedicated hospitalist physician alone (strategy A) or in conjunction with a nurse (strategy B) overlooked the postoperative period to ensure adherence and correct inadequacies. Finally, a multidisciplinary team approach (strategy C) focused on promoting adequate VTE prophylaxis across multiple stages of care-from the operating room (ie, preoperative team-based checklist) to collaboration with clinical pharmacists in the postoperative period-was implemented.
Results: We analysed 2074 surgical patients: 783 from January to June 2019 (strategy A), 669 from July 2019 to May 2020 (strategy B), and 622 from June to December 2020 (strategy C). VTE prophylaxis adherence rates for strategies (A), (B) and (C) were (median (25th-75th percentile)) 43.29% (31.82-51.69), 50% (42.57-55.80) and 92.31% (91.38-93.51), respectively (p<0.001; C>A=B). There was a significant reduction in non-compliance on all analysed criteria (risk stratification (A (25.5%), B (22%), C (6%)), medical documentation (A (68%), B (55.2%) C (9%)) and medical prescription (A (51.85%), B (48%), C (6.10%)) after implementation of strategy C (p<0.05). Additionally, a significant increase in compliance with adequate dosage, dosing interval and scheduling of the prophylactic regimen was observed.
Conclusion: Perioperative VTE prophylaxis strategies that relied exclusively on physicians and/or nurses were associated with suboptimal execution and prevention. A multidisciplinary team-based approach that covers multiple stages of patient care significantly increased adherence to adequate VTE prophylaxis in surgical patients at high risk of developing perioperative VTE.

Introduction: Compared with the guideline-recommended use of low-molecular weight heparin (LMWH) for 28 days to prevent venous thromboembolism (VTE) after cytoreductive surgery, oral rivaroxaban avoids the pain and inconvenience of daily injections and reduces medical expenses. The proposed randomised controlled trial (RCT) aims to compare the efficacy and safety of rivaroxaban and enoxaparin in preventing VTE in patients after surgery for gynaecological malignancies and to provide a reference for clinical medication prevention.
Methods And Analysis: This is a single-centre, randomised, controlled, open-label and assessor-blind clinical trial.

Traumatic brain injury (TBI) remains a leading cause of morbidity and mortality among trauma patients. The care of these patients continues to be a complex endeavor with prevention of associated complications, often requiring as much attention as that of the treatment of the primary injury. Paramount among these are venous thromboembolic events (VTE) due to their high incidence, additive effect on the risk of morbidity and mortality, and the careful balance that must be utilized in their diagnosis and treatment to prevent progression of the brain injury itself.

Victims of trauma were at a higher risk of developing thromboembolic complications, and thus various agents were used for prophylaxis. Multiple studies recommended holding these agents in the perioperative period to decrease the potential complications of additional bleeding, wound issues, hematoma etc.

Vitamin D (VD) is a vital lipophilic secosteroid hormone known for its essential role in maintaining skeletal health and regulating calcium and phosphate metabolism. Recent evidence has begun to illuminate its significance beyond bone health, particularly in relation to thrombosis-a condition characterized by blood clot formation within the vascular system that can lead to serious cardiovascular events such as myocardial infarction and stroke. VD deficiency, defined as a plasma 25-hydroxyVD level below 25 nmol/L, affects a substantial portion of the global population, with prevalence rates ranging from 8% to 18%.

Background: Cardiac surgery patients are at increased risk for venous thromboembolism (VTE). Prevention is the most critical strategy to reduce VTE-associated morbidity and death. However, there is a lack of data on the optimal approach to VTE prophylaxis in this population of high-risk patients.
