National Health Survey
The National Health Survey (NHS) uses three factors to determine whether or not a person is counted as having a particular condition: whether the condition is current, whether it is long term and whether it was medically diagnosed. The combination of these factors required for a person to count as having the condition varies according to nature of the condition. For example, some conditions, such as diabetes and HSVD, once diagnosed, are seen to be lifelong. Even if a person no longer reports symptoms, they still count as having the condition. While other conditions, such as depression, asthma, cancer or back problems, can be lifelong, episodic or in complete remission.
Most conditions do not need the respondent to have been diagnosed by a doctor or nurse. The respondent is counted if they said they have the condition. However, in cases where the respondent said they had diabetes or HSVD and that the condition was not current, they need to have received a diagnosis to be counted.

National Hospital Morbidity Database
Chronic conditions in the AIHW National Hospital Morbidity Database (NHMD) are identified based on codes from the ICD-10-AM. Procedures are identified based on ACHI codes. For this report, the codes used can be found in Table 2 to Table 4 below. For NHMD analysis, hospitalisations for which the care type was reported as Newborn (without qualified days), and records for Hospital boarders and Posthumous organ procurement have been excluded.
