HbA1c measurement—type 2 diabetes (PI05 and PI06)

Indicators related to HbA1c in the national Key Performance Indicators (nKPIs) are:

  • the proportion of Indigenous regular clients with type 2 diabetes who had a HbA1c measurement result recorded within the previous 6 months or within the previous 12 months
  • the proportion of Indigenous regular clients with type 2 diabetes who had a HbA1c measurement result recorded within the previous 6 months or within the previous 12 months that was within specified ranges.

Why HbA1c is important

The HbA1c (glycosylated haemoglobin or glycated haemoglobin) blood test gives an indication of whether blood glucose levels have been higher than normal over the preceding 6–8 weeks by looking at how much sugar (glucose) is bound in red blood cells. It is regarded as the gold standard for assessing glycaemic control.

People who have diabetes need this test regularly to see if their levels are staying within range and whether they need to adjust their diabetes management. The general glycated haemoglobin (HbA1c) target in people with type 2 diabetes is ≤53 mmol/mol (≤7%) (RACGP 2016).

HbA1c result recorded—type 2 diabetes (PI05)

This indicator is the proportion of Indigenous regular clients with type 2 diabetes who had a HbA1c measurement result recorded within the previous 6 months or within the previous 12 months.

It is collected for males and females in age groups from 0–4 to 65 and over. It is presented here for males and females in age groups:

  • under 35
  • 35–44
  • 45–54
  • 55–64
  • 65 and over.

At June 2019:

  • 52% of Indigenous regular clients with type 2 diabetes had a HbA1c measurement result recorded within the previous 6 months
  • 67% of Indigenous regular clients with type 2 diabetes had a HbA1c measurement result recorded within the previous 12 months.

HbA1c result recorded—type 2 diabetes, by time period and reporting period

This Tableau visualisation shows the percentage of Indigenous regular clients with type 2 diabetes who had a HbA1c measurement result recorded by time period of measurement (select for 6 months or 12 months) and reporting period (June 2017, December 2017, June 2018, December 2018 and June 2019).

Data supporting this visualisation are available in Excel supplementary data tables at Data.

Visualisation not available for printing

Having a HbA1c measurement result recorded within the previous 6 months was highest in:

  • Western Australia (56%)
  • Major cities and Remote areas (both 54%).

It was lowest in:

  • New South Wales/the Australian Capital Territory (combined, 49%)
  • Inner regional areas (50%).

Having a HbA1c measurement result recorded within the previous 12 months was highest in:

  • Queensland and Western Australia (both 72%)
  • Remote areas (70%).

It was lowest in:

  • the Northern Territory (62%)
  • Inner regional areas (63%).

HbA1c result recorded—type 2 diabetes, by time period and either state/territory or remoteness, reporting period

Two Tableau visualisations are presented here. The first shows the percentage of Indigenous regular clients with type 2 diabetes who had a HbA1c measurement result recorded by time period of measurement (select for 6 months or 12 months) for either:

  • state/territory (NSW/ACT, Vic, Qld, WA, SA, Tas, NT, Australia)
  • remoteness area (Major cities, Inner regional, Outer regional, Remote, Very remote, Australia).

Reporting periods of either June 2017, December 2017, June 2018, December 2018 or June 2019 can be selected.

The second visualisation shows the selected information from the first visualisation by sex (male, female) and age group (<35, 35–44, 45–54, 55–64, 65+).

Data supporting this visualisation are available in Excel supplementary data tables at Data.

HbA1c result—type 2 diabetes (PI06)

This indicator is the proportion of Indigenous regular clients with type 2 diabetes who had a HbA1c measurement result recorded within the previous 6 months or within the previous 12 months (mmol/mol):

  • ≤53 (≤7%)
  • >53–≤64 (>7%–≤8%)
  • >64–<86 (>8%–<10%)
  • ≥86 (≤10%).

It is collected for males and females in age groups:

  • under 35
  • 35–44
  • 45–54
  • 55–64
  • 65 and over.

At June 2019:

  • 39% of Indigenous regular clients with type 2 diabetes had a HbA1c measurement result of ≤53 mmol/mol recorded within the previous 6 months
  • 39% had a HbA1c measurement result of ≤53 mmol/mol recorded within the previous 12 months.
