AI Article Synopsis
- The study examines the risk of venous thromboembolism (VTE), which includes deep venous thrombosis and pulmonary embolism, following total knee arthroplasty (TKA), highlighting that African Americans face a higher risk compared to other racial groups.
- The research involved analyzing data from over 96,000 patients who underwent TKA from 2010 to 2014, using demographics and multivariate logistic regression to compare complications across different races.
- Findings indicate that Black patients had a significantly higher rate of complications and VTE compared to Whites, prompting calls for further investigation into the underlying causes of this racial disparity in postoperative outcomes.
Article Abstract
Background: Venous thromboembolism (VTE) (deep venous thrombosis and pulmonary embolism) is a known complication following total knee arthroplasty (TKA). Recent literature has identified differences in VTE risk based on race with African Americans having higher risk of VTE. This study evaluated the impact of race on VTE following TKA using a large multicenter database.
Methods: We queried the American College of Surgeons National Surgical Quality Improvement Program to identify patients who underwent primary TKA in 2010-2014. Patients were stratified based on race: Asian, Black/African American, White, and Other. Demographics were compared to determine the impact on 30-day postoperative complications. Multivariate logistic regression analysis was performed to control for confounding demographics and comorbidities between races. Primary outcomes included overall complications and VTE.
Results: In total, 96,230 patients were included. Univariate analysis demonstrated that Blacks had a significantly higher rate of any complication (5.5%), deep venous thrombosis (1.3%), and pulmonary embolism (1.1%) than other races (P = .007, P < .001, and P < .001, respectively). Overall mortality rate did not differ between races (P = .26). Multivariate regression analysis identified that Blacks were significantly more likely to have a VTE than Whites (odds ratio 1.7, 95% confidence interval 1.4-2.0). Overall complications were significantly higher for Blacks than Whites (odds ratio 1.1, 95% confidence interval 1.02-1.3). There were no differences in the rates of VTE or overall complications between Asians/Other races and Whites.
Conclusion: Blacks have a significantly higher risk of VTE following primary TKA than other races. Future studies should investigate causes for this disparity.

Background: Venous thromboembolism (VTE) and atrial fibrillation (AF) disproportionately affect older adults, who are at increased risk of bleeding from treatment with anticoagulant therapy. The impact of bleeding on older adults' quality of life (QoL) is poorly understood due to the lack of a validated measure of their experience. This study's purpose is to describe the first evidence-based steps in developing a new condition-specific patient-reported outcome measure (PROM) for the effect of anticoagulant-related bleeding on older adults' QoL.

Background: Orthopedic trauma patients are at high risk for venous thromboembolic (VTE) complications. Despite this, VTE prophylaxis is often held peri-operatively out of concern for increased bleeding and associated complications. This review's purpose is to examine guidelines and studies on withholding prophylactic anticoagulation peri-operatively.

Objective: This study aimed to compare perioperative outcomes and progression-free and overall survival in patients with chronic kidney disease (CKD) versus those without after hyperthermic intra-peritoneal chemotherapy (HIPEC) for ovarian cancer.
Methods: This is a retrospective, single-institution cohort study of patients with ovarian cancer treated with HIPEC at the Cleveland Clinic from January 2009 to December 2022. All patients received HIPEC with cisplatin and renal protection with mannitol and furosemide.
Objectives: To assess the impact of a positive history of venous thromboembolism (VTE) on perioperative outcomes, including length of in-hospital stay, readmission rates, 90-day postoperative complications, and healthcare costs in bladder cancer (BCa) patients undergoing transurethral resection of bladder tumour (TURBT) in the United States.
Patients And Methods: Patients aged ≥18 years with a BCa diagnosis undergoing TURBT were identified in the Merative® Marketscan® Research de-identified databases between 2007 and 2021. Multivariable logistic regression adjusted by relevant perioperative confounders was used to investigate the association between diagnosis of VTE before TURBT and 90-day complication rates, new postoperative VTE events, re-hospitalization, and total hospital expenditures (2021 US dollars).

Venous thromboembolism remains a major cause of morbidity and mortality among ambulatory cancer patients, necessitating effective risk assessment and prevention strategies. Despite the availability of risk assessment models and guidelines recommending primary thromboprophylaxis with low-molecular-weight heparins or direct oral anticoagulants, the application of these strategies is inconsistent. This review provides an overview of the current state-of-the-art venous thromboembolism risk assessment and thromboprophylaxis in ambulatory patients with cancer, focusing on existing risk assessment models and the latest guideline recommendations.
