7               Kind of injury, disease or death to which this Statement of Principles relates
(1)          This Statement of Principles is about bronchiolitis obliterans organising pneumonia and death from bronchiolitis obliterans organising pneumonia.
Meaning of bronchiolitis obliterans organising pneumonia
(2)          For the purposes of this Statement of Principles, bronchiolitis obliterans organising pneumonia:
(a)           means a histological pattern of organising pneumonia consisting of the patchy filling of alveoli, alveolar ducts and bronchioles by loose plugs of granulation tissue consisting of fibroblasts embedded in connective tissue, arising in response to lung injury and resulting in excessive proliferation of healing tissue, with:
                (i)            respiratory symptoms; or
                (ii)         other clinical evidence of pulmonary dysfunction; and
(b)          excludes:
                (i)            organising pneumonia secondary to infectious pneumonia or acute respiratory distress syndrome;
                (ii)         organising pneumonia that occurs in the presence of another interstitial lung disease and is not the dominant histological finding;
                (iii)       organising pneumonia that occurs as a pulmonary manifestation of a systemic disease; and
                (iv)        pulmonary inflammation that is confined to the bronchioles (obliterative bronchiolitis, proliferative bronchiolitis).
            Note 1: Bronchiolitis obliterans organising pneumonia ('BOOP') is also known as cryptogenic organising pneumonia.
            Note 2: Although the definition refers to a histological pattern, the diagnosis of bronchiolitis obliterans organising pneumonia can be made in patients with typical clinical and radiographic features without a lung biopsy being undertaken.
Death from bronchiolitis obliterans organising pneumonia
(3)          For the purposes of this Statement of Principles, bronchiolitis obliterans organising pneumonia, in relation to a person, includes death from a terminal event or condition that was contributed to by the person's bronchiolitis obliterans organising pneumonia.
Note: terminal event is defined in the Schedule 1 – Dictionary.
