Deep venous thrombosis (DVT) and the subsequent development of venous thromboembolism (VTE) are a significant cause of mortality, morbidity, and cost of care in trauma patients. This study aims to: 1) validate 5 as a critical threshold for high risk; 2) validate risk factors associated
with DVT/VTE development; 3) evaluate exogenous estrogen and smoking as risk factors; and 4) analyze daily risk assessment profile (RAP) score changes. We performed a retrospective chart review of trauma patients admitted from January 2001 through December 2005. Univariate odds ratios were
performed to assess potential risk factors for VTE. Of the 110 charts reviewed, 31 patients had confirmed DVT/VTE. Three of 26 patients with an RAP score < 5 suffered a VTE; one resulted in death. Significant risk factors included femoral venous line insertion, operation longer than 2 hours,
head abbreviated injury score > 2, and Glasgow Coma Scale score < 8. RAP fluctuations were due to a changing Glasgow Coma Scale score, and whether the patient received more than four transfusions, was in surgery for more than 2 hours, or required a femoral venous catheter or major venous
repair. The RAP critical value (5) was not validated. We recommend all trauma patients be treated with prophylactic anticoagulants throughout the hospital stay unless clear contraindications exist.
