1 Name
This is the Statement of Principles concerning deep vein thrombosis (Balance of Probabilities) (No. 36 of 2021).
2 Commencement
This instrument commences on 5 April 2021.
3 Authority
This instrument is made under subsection 196B(3) of the Veterans' Entitlements Act 1986.
4 Repeal
The Statement of Principles concerning deep vein thrombosis No. 55 of 2012 (Federal Register of Legislation No. F2012L01797) made under subsection 196B(3) of the VEA is repealed.
5 Application
This instrument applies to a claim to which section 120B of the VEA or section 339 of the Military Rehabilitation and Compensation Act 2004 applies.
6 Definitions
The terms defined in the Schedule 1 - Dictionary have the meaning given when used in this instrument.
7 Kind of injury, disease or death to which this Statement of Principles relates
(1) This Statement of Principles is about deep vein thrombosis and death from deep vein thrombosis.
Meaning of deep vein thrombosis
(2) For the purposes of this Statement of Principles, deep vein thrombosis:
(a) means formation of a blood clot within the deep venous system; and
(b) excludes thrombosis of the:
(i) retinal veins;
(ii) cerebral veins;
(iii) pulmonary veins;
(iv) hepatic vein;
(v) renal veins;
(vi) portal vein; and
(vii) mesenteric veins.
Death from deep vein thrombosis
(3) For the purposes of this Statement of Principles, deep vein thrombosis, in relation to a person, includes death from a terminal event or condition that was contributed to by the person's deep vein thrombosis.
Note: terminal event is defined in the Schedule 1 - Dictionary.
8 Basis for determining the factors
On the sound medical‑scientific evidence available, the Repatriation Medical Authority is of the view that it is more probable than not that deep vein thrombosis and death from deep vein thrombosis can be related to relevant service rendered by veterans or members of the Forces under the VEA, or members under the MRCA.
Note: MRCA, relevant service and VEA are defined in the Schedule 1 - Dictionary.
9 Factors that must exist
At least one of the following factors must exist before it can be said that, on the balance of probabilities, deep vein thrombosis or death from deep vein thrombosis is connected with the circumstances of a person's relevant service:
(1) having superficial vein thrombosis within the six months before the clinical onset of deep vein thrombosis;
(2) having external compression of the affected vein or a vein draining the affected vein, at the time of the clinical onset of deep vein thrombosis;
Note: external compression of the affected vein or a vein draining the affected vein is defined in the Schedule 1 - Dictionary.
(3) having an infection involving the affected vein at the time of the clinical onset of deep vein thrombosis;
(4) for deep vein thrombosis in an upper limb only, engagement in exercise of the affected upper limb within the seven days before the clinical onset of deep vein thrombosis;
Note: exercise of the affected upper limb is defined in the Schedule 1 - Dictionary.
(5) having acute myocardial infarction within the three months before the clinical onset of deep vein thrombosis;
(6) having heart failure at the time of the clinical onset of deep vein thrombosis;
(7) having a malignant neoplasm at the time of the clinical onset of deep vein thrombosis;
(8) having an aneurysm of the affected vein at the time of the clinical onset of deep vein thrombosis;
(9) being overweight or obese at the time of the clinical onset of deep vein thrombosis;
Note: being overweight or obese is defined in the Schedule 1 - Dictionary.

(11) being pregnant within the three months before the clinical onset of deep vein thrombosis;
(12) having infection with human immunodeficiency virus or hepatitis C virus at the time of the clinical onset of deep vein thrombosis;
(13) having infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) within the three months before the clinical onset of deep vein thrombosis;
Note: SARS-CoV-2 is the virus which causes coronavirus disease 2019 (COVID-19).
(14) having an autoimmune disease at the time of the clinical onset of deep vein thrombosis;
Note: Examples of autoimmune diseases that may cause deep vein thrombosis include rheumatoid arthritis, polymyositis and Sjögren syndrome.
(15) having diabetes mellitus at the time of the clinical onset of deep vein thrombosis;
(16) having a hypercoagulable state as specified at the time of the clinical onset of deep vein thrombosis;
Note: hypercoagulable state as specified is defined in the Schedule 1 - Dictionary.
(17) having a kidney disease from the specified list of kidney diseases at the time of the clinical onset of deep vein thrombosis;
Note: specified list of kidney diseases is defined in the Schedule 1 - Dictionary.
(18) having a device implanted within the affected vein for a continuous period of at least 24 hours within the three months before the clinical onset of deep vein thrombosis;
Note: Examples of implanted devices include a central venous catheter, an indwelling cardiac pacemaker and defibrillator leads.
(19) having surgery requiring a general, spinal or epidural anaesthetic within the six months before the clinical onset of deep vein thrombosis;
(20) having an injury or illness as specified within the three months before the clinical onset of deep vein thrombosis;
Note: injury or illness as specified is defined in the Schedule 1 - Dictionary.
(21) having restricted mobility for a continuous period of at least four hours within the four weeks before the clinical onset of deep vein thrombosis;
Note: Examples of situations in which restricted mobility can occur include travel by road, rail or air and physical restraint.
(22) having a neurological disease that causes loss or impairment of motor function of a limb within the three months before the clinical onset of deep vein thrombosis;
Note: Examples of neurological diseases that cause loss or impairment of motor function of a limb include cerebrovascular accident, multiple sclerosis and motor neurone disease.
(23) taking a drug from the specified list of drugs within the three months before the clinical onset of deep vein thrombosis;
Note: specified list of drugs is defined in the Schedule 1 - Dictionary.
(24) taking combined estrogen-progestogen contraception or taking menopausal hormone therapy as an oral estrogen, or a non-oral estrogen combined with a progestogen, for a continuous period of at least four weeks, within the three months before the clinical onset of deep vein thrombosis;
Note: menopausal hormone therapy is defined in the Schedule 1 - Dictionary.
(25) having smoked tobacco products:
(a) in an amount of at least one pack-year before the clinical onset of deep vein thrombosis; or
(b) in an amount of at least 10 cigarettes per day, or the equivalent thereof in other tobacco products, for a period of at least three months before the clinical onset of deep vein thrombosis; and
if smoking has ceased before the clinical onset of deep vein thrombosis, then that onset occurred within six months of cessation;
Note: cigarettes per day, or the equivalent thereof in other tobacco products and pack-year are defined in the Schedule 1 - Dictionary.
(26) being at an altitude of at least 3,000 metres for a continuous period of at least five days within the three months before the clinical onset of deep vein thrombosis;
(27) inability to obtain appropriate clinical management for deep vein thrombosis.
10 Relationship to service
(1) The existence in a person of any factor referred to in section 9, must be related to the relevant service rendered by the person.
(2) The factor set out in subsection 9(27) applies only to material contribution to, or aggravation of, deep vein thrombosis where the person's deep vein thrombosis was suffered or contracted before or during (but did not arise out of) the person's relevant service.
11 Factors referring to an injury or disease covered by another Statement of Principles
In this Statement of Principles:
(1) if a factor referred to in section 9 applies in relation to a person; and
(2) that factor refers to an injury or disease in respect of which a Statement of Principles has been determined under subsection 196B(3) of the VEA;
then the factors in that Statement of Principles apply in accordance with the terms of that Statement of Principles as in force from time to time.
