- Association Between Enoxaparin Dosage Adjusted by Anti-Factor Xa Trough Level and Clinically Evident Venous Thromboembolism After Trauma.

- JAMA Surg. 2016 Nov 1;151(11):1006-1013.
Rationale for inclusion: Trauma patients who received enoxaparin adjusted by anti-Xa trough levels were compared to standard 30mg BID dosing. Subprophylactic anti-Xa levels and VTE were more common in the standard dosing group.

- J Am Coll Surg. 2016 Oct;223(4):621-631.e5.
Rationale for inclusion: TQIP patients with severe TBI (GCS≤8) were compared with respect to initiation of VTE prophylaxis before or after 72hrs. Early VTE prophylaxis was associated with decreased PE, DVT but no increase in late neurosurgical intervention or death.

- JAMA Surg. 2014 Feb;149(2):194-202.
Rationale for inclusion: The strength of evidence is low but supports the association of IVC filter placement with a lower incidence of PE and fatal PE in trauma patients. Which patients experience benefit enough to outweigh the harms associated with IVC filter placement remains unclear.

- J Trauma Acute Care Surg. 2012 Dec;73(6):1434-41.
Rationale for inclusion: TBI progression rates after starting enoxaparin in small, stable injuries 24 hours after injury are similar to those of placebo and are subclinical.

- Arch Surg. 2012 Oct;147(10):901-7.
Rationale for inclusion: Implementation of a mandatory computerized decision tool improved compliance with VTE prophylaxis guidelines in trauma patients, resulting in lower rate of VTE events in patients who were not ordered appropriate prophylaxis.

Rationale for inclusion: Review of complications after IVC filter placement showed that IVCF were placed frequently for prophylaxis in the absence of VTE conditions.

Rationale for inclusion: Enoxaparin should be considered as an option for early VTE prophylaxis in selected patients with blunt TBI.

Rationale for inclusion: Identifiable risk factors exist for development if VTE; additionally, many patients had IVC filters placed without risk factors.
