Notes: 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. 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. Comorbidities reported in Table 5.1 were classified as follows: respiratory infections (J0–J22); chronic obstructive pulmonary disease (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–C97). Of all people hospitalised with asthma in 2005–06, 40% had at least one of these selected comorbid conditions. CI = confidence interval.
