  • abdominal or pelvic surgery for cancer
  • multiple major trauma injuries
  • acute spinal cord injury with paresis

moderate risk

  • not in high or low risk categories

low risk

  • ambulatory patient without VTE risk factors (see below)
  • ambulatory patient with VTE risk factors but expected hospital LOS < 2 days
  • minor surgery (operating time < 30 minutes) in patient with VTE risk factors

venous thromboembolism (VTE) risk factors

  • Prolonged immobility or paralysis.
  • Prior venous thromboembolic disease
  • Malignancy
  • Trauma, spinal cord injury and burns
  • Fractures of the pelvis, hip or leg
  • Presence of hypercoagulable state
  • Stroke

  • Oestrogen use
  • Congestive cardiac failure
  • Myocardial infarction
  • Active inflammatory bowel disease

  • Varicose veins
  • Respiratory failure / smoker
  • Long-haul travel
  • Indwelling large vein catheter includes peripheral/central lines, Hickmann’s, etc.
