. . Not applicable Notes

1. Data are included only for those states/territories for which the Indigenous identifier was considered reliable, that is, Queensland, Western Australia, South Australia and the Northern Territory (public hospitals only) (all years) and New South Wales and Victoria (2004–05 and 2005–06 only).

2. Asthma was classified according to International Statistical Classification of Diseases and Related Health Problems, 10th Revision, Australian Modification (ICD-10-AM) codes J45 and J46.

3. Separations for which the care type was reported as Newborn with no qualified days, and records for Hospital boarders and Posthumous organ procurement have been excluded.

4. Comorbidities were classified as follows: respiratory infections (J0–J22); COPD and bronchiectasis (J40–J44, J47); non-infectious upper respiratory conditions (includes rhinitis, sinusitis, laryngitis) (J30–39); diabetes mellitus (E10–E14); heart, stroke and vascular disease (I20–I25, I60–I69, I50, I70–I79); arthritis and osteoporosis (M00–M25, M80–M82); mental and behavioural disorders (F30–F39, F40–F48, F90–F98); and malignant neoplasms (i.e. cancer) (C00–C96).

5. ‘Other’ includes both non-Indigenous persons and persons for whom Indigenous status was not stated or was inadequately described. Indigenous status was not stated or was inadequately described for 1.9% of hospital separations among other Australians in 2003–04 to 2005–06 where asthma was the principal diagnosis.

6. CI = confidence interval.
