Risk factors for thromboembolism:
(1) Injury Severity Scores (ISS) >= 9, with further increase if >= 25
(2) major vascular injury
(3) craniotomy
(4) central venous catheters
(5) age >= 5, with further increase if >= 10 years of age
Procedures associated with increased risk:
(1) open reduction and internal fixation of lower extremity fractures
(2) laparotomy
(3) spinal procedure
These proceedures (plus craniotomy) are performed for major injuries to head, spine, thorax, abdomen or extremities, reflecting a high ISS.
The relative risk was high (> 15) for:
(1) ISS >= 25
(2) major vascular injury
The relative risk was moderate (5-7) for:
(1) ISS >= 9
(2) central venous catheter
(3) craniotomy
(4) age >= 10
The relative risk was low (2) for:
(1) age 5 - 9
