B Learning Objectives: b The Risk Assessment Profile (RAP) stratifies risk for venous thromboembolism (VTE) based on underlying conditions, injuries, iatrogenic factors, and age post-trauma. This study sought to compare VTE incidence between elderly, high-risk trauma patients receiving unfractionated heparin (UFH) or enoxaparin chemoprophylaxis and to evaluate an age-modified RAP score for elderly patients. RAP >=8 and RAP-AM >=5 best identified VTE risk; further validation is needed in a general elderly trauma population. [Extracted from the article]
