Testing for type 2 diabetes in Indigenous Australians: guideline recommendations and current practice

Area of Science:

• Public Health
• Indigenous Health
• Diabetes Management

Background:

• Diabetes is a significant health concern for Indigenous Australians.
• Aboriginal Controlled Community Health Services (ACCHS) play a crucial role in delivering primary healthcare to Indigenous communities.
• National guidelines exist for diabetes screening in Indigenous populations.

Purpose of the Study:

• To assess the proportion of Indigenous patients tested for diabetes according to national guidelines.
• To identify patient characteristics associated with diabetes testing rates within ACCHS.
• To evaluate the adherence to different diabetes screening frequencies (3-yearly vs. annual).

Main Methods:

• A cross-sectional study analyzed de-identified electronic health records from 18 ACCHS across Australia.
• Data from 20,978 adult Indigenous Australians without diagnosed diabetes were included (July 2010 - June 2013).
• Screening proportions were compared against guidelines from NHMRC, RACGP, Diabetes Australia, and NACCHO.

Main Results:

• 74% of Indigenous adults and 77% of those aged 35+ received 3-yearly diabetes testing.
• Annual diabetes testing rates for patients aged 18+ were low at 18%, with significant variation between services (0.1-43%).
• Patients under 50, transient attendees, and those with infrequent service use were less likely to be tested.

Conclusions:

• While 3-yearly diabetes screening is often met, recommended annual testing rates are rarely achieved in ACCHS.
• Significant variations in testing proportions exist across different ACCHS.
• ACCHSs may require additional support and resources to enhance diabetes screening uptake among Indigenous Australians.
