1 Name

This is the Statement of Principles concerning gastric ulcer and gastric erosion (Reasonable Hypothesis) (No. 51 of 2024).

2 Commencement

This instrument commences on 23 July 2024.

3 Authority

This instrument is made under subsection 196B(2) of the Veterans' Entitlements Act 1986.

4 Repeal

The Statement of Principles concerning gastric ulcer and duodenal ulcer No. 61 of 2015 (Federal Register of Legislation No. F2015L00657) made under subsection 196B(2) and (8) of the VEA is repealed.

5 Application

This instrument applies to a claim to which section 120A of the VEA or section 338 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 gastric ulcer and gastric erosion and death from gastric ulcer and gastric erosion.

Meaning of gastric ulcer and gastric erosion

(2) For the purposes of this Statement of Principles, gastric ulcer and gastric erosion:

(a) means a non-malignant disruption in the mucosal surface of the stomach; and

(b) includes ulcers or erosions due to gastric foreign bodies; and

(i) acute haemorrhagic gastritis; and

(ii) stomach perforations from external trauma such as stabbing, explosive blast injury or gunshot injury.

Note: A gastric erosion is a disruption in the mucosal surface of the stomach above the lamina propria, and a gastric ulcer is a disruption in the mucosal surface of stomach that extends past the lamina propria and through the muscularis mucosa into the submucosa.

(3) While gastric ulcer and gastric erosion attracts ICD‑10‑AM code K25 in applying this Statement of Principles the meaning of gastric ulcer and gastric erosion is that given in subsection (2).

(4) For subsection (3), a reference to an ICD-10-AM code is a reference to the code assigned to a particular kind of injury or disease in The International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification (ICD-10-AM), Tenth Edition, effective date of 1 July 2017, copyrighted by the Independent Hospital Pricing Authority, ISBN 978-1-76007-296-4.

Death from gastric ulcer and gastric erosion

(5) For the purposes of this Statement of Principles, gastric ulcer and gastric erosion, in relation to a person, includes death from a terminal event or condition that was contributed to by the person's gastric ulcer and gastric erosion.

Note: terminal event is defined in the Schedule 1 – Dictionary.

8 Basis for determining the factors

The Repatriation Medical Authority is of the view that there is sound medical-scientific evidence that indicates that gastric ulcer and gastric erosion and death from gastric ulcer and gastric erosion can be related to relevant service rendered by veterans, members of Peacekeeping Forces, 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 as a minimum exist before it can be said that a reasonable hypothesis has been raised connecting gastric ulcer and gastric erosion or death from gastric ulcer and gastric erosion with the circumstances of a person's relevant service:

(1) being a prisoner of war before clinical onset or clinical worsening;

(2) having Helicobacter pylori infection of the stomach at the time of clinical onset or clinical worsening;

(3) having an infection of the gastric mucosa by one of the following organisms:

(b) cytomegalovirus;

(d) fungi (such as Candida species or Mucormycetes);

(e) Helicobacter heilmannii;

(f) Mycobacterium tuberculosis;

(g) Strongyloides stercoralis (causing strongyloidiasis); or

(h) Treponema pallidum (causing syphilis);

at the time of clinical onset or clinical worsening;

(4) having a critical illness or injury within the 30 days before clinical onset or clinical worsening;

Note: critical illness or injury is defined in the Schedule 1 - Dictionary.

(5) undergoing a course of radiotherapy for cancer, where the stomach or duodenum was in the field of radiation, within the one year before clinical onset or clinical worsening;

(6) having received a cumulative equivalent dose of at least 10 sieverts of ionising radiation to the stomach or duodenum within the one year before clinical onset or clinical worsening;

Note: cumulative equivalent dose is defined in the Schedule 1 - Dictionary.

(7) undergoing 90Yttrium microsphere therapy for primary and metastatic liver tumours, within the one year before clinical onset or clinical worsening;

(8) having contact with a nasogastric tube or other foreign objects or extraneous material at the site of the ulcer or erosion at the time of clinical onset or clinical worsening;

(9) having partial gastrectomy within the 5 years before clinical onset or clinical worsening of gastric ulcer or gastric erosion;

(10) having endoscopic mucosal resection or endoscopic sub-mucosal dissection of the gastric mucosa at the time of clinical onset or clinical worsening;

(11) having bariatric surgery involving sleeve gastrectomy or gastric banding within the 5 years before clinical onset or clinical worsening;

(12) having a gastrin-secreting tumour at the time of clinical onset or clinical worsening;

(13) smoking at least 10 cigarettes a day for at least one year within the 2 years before clinical onset or clinical worsening;

(14) being treated with a non-topical non-steroidal anti-inflammatory drug, or aspirin, at least every other day during a continuous period of at least 8 days, within the 3 months before clinical onset or clinical worsening;

(15) having a solid organ or bone marrow transplant before clinical onset or clinical worsening;

(16) being treated with an antineoplastic agent within the 3 months before clinical onset or clinical worsening;

Note: antineoplastic agent is defined in the Schedule 1 - Dictionary.

Note: The bleeding of a gastric ulcer is considered to be a clinical worsening.

(29) inability to obtain appropriate clinical management for gastric ulcer and gastric erosion.

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 clinical worsening aspects of factors set out in section 9 apply only to material contribution to, or aggravation of, gastric ulcer and gastric erosion where the person's gastric ulcer and gastric erosion 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(2) 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.
