Data period

• 2017–18 to 2021–22

Region types reported

• ASGS 2016 Indigenous Structure regions: Indigenous Regions (IREG)


• ESRI dashboard is based on 2021 boundaries, so for selected regions map boundaries do not exactly match data boundaries. This includes:

  • SA4s: Sydney – Blacktown; Sydney – Parramatta; Sydney - Outer South West; Sydney – South West and Sydney – Sutherland.
  
  
  
  

Suppression rules

• Data have been suppressed if the number is less than 5 for the Australian Capital Territory and between 1 and 4 for the other states and territories. Where required, consequential suppression has been applied to prevent back-calculation.


• Data have been suppressed if the denominator for the percentage is less than 100, due to concerns about the reliability of percentages based on small denominators.

Notes

• Hospitalisations due to CKD are based on the principal diagnosis with the International Classification of Disease 10^th Revision (ICD-10) codes: E102, E112, E132, E142, I150, I151, N391, N392, D593, B520, E853, T824, T861, Z490, Z940, Z992, I12, I13, N11, N12, N14, N15, N16, N18, N19, N00-N08, N25-N28, Q60-Q63.

• Data are for persons aged 1 and over.


• Hospitalisations with the care types “newborn with unqualified days only” (7.3), “organ procurement - posthumous” (9) or “hospital boarder” (10) have been excluded from the analysis.

Suppression rules

• Data have been suppressed if the denominator for the percentage is less than 100, due to concerns about the reliability of percentages based on small denominators.


• Data have been suppressed if long-term health condition is not stated for >50% of the relevant population, due to relatively high exposure to potential bias.


• Data have been flagged if long-term health condition is not stated for 25%–50% of the relevant population, due to relatively high exposure to potential bias.

Notes

• Count of long-term health condition data is derived from responses to the long-term health conditions question: ‘has the person been told by a doctor or nurse that they have any of these long-term health conditions?’.


• This was a new question for the 2021 ABS Census of Population and Housing.


• Data have been randomly adjusted by the ABS to protect confidentiality. No reliance should be placed on small numbers.

Notes

There are 2 main forms of dialysis: haemodialysis (which occurs outside the body via a machine) and peritoneal dialysis (which occurs inside the patient’s body via the lining of the abdominal cavity).

Notes

• Haemodialysis is a form of dialysis where a machine is connected to a person’s bloodstream to filter the blood externally. During haemodialysis, the patient is usually connected to the machine for about 4–5 hours 3 times per week, when all their blood passes through the machine about 6 times. Home haemodialysis is haemodialysis performed at home where patients may have the option of dialysing more frequently for a shorter period (5–7 times per week for about 2 hours) or nocturnally (6 nights per week for about 8 hours). During a haemodialysis session the patient is unable to move away from the machine, though they can sleep and perform activities such as reading, talking, or using a computer.

Notes

• Peritoneal dialysis is a form of dialysis where a solution is pumped into the abdominal cavity where the body’s own peritoneum membrane acts as a dialysis filter to remove waste products and water. As the necessary equipment is portable, peritoneal dialysis can be performed almost anywhere. Patients do not need to be in a hospital or clinic, and can usually manage the procedure without assistance.
