Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
During a 6-month period, consecutive adults presenting to one Level I urban trauma center were screened for eligibility, enrolled and assigned to a treatment category using previously-developed clinical guidelines.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Of 105 enrolled participants, 18 were excluded from analysis (13 discharged or transferred prior to second venous ultrasonography; 4 received non-study DVT prophylaxis; 1 had a known protein-C deficiency).

Reporting Groups
  Description
Fondaparinux Sodium Patients at high risk or very high risk for venous thromboembolism received fondaparinux 2.5mg via subcutaneous administration (SubQ) daily, with (very high risk) or without (high risk) mechanical compression upon admission or by 3rd day after injury.
No Fondaparinux Patients at high risk or very high risk for venous thromboembolism AND contraindication to anticoagulant administration received mechanical compression, with (very high risk) or without (high risk) possible temporary inferior vena cava (IVC) filter (prn as determined by caregiver).
