Data 'Stability'

Comments on the reliability of the data given its apparent stability compared to previous ANDIAB studies

Page last updated: December 2011

Comparison of results from the eight years of ANDIAB surveys [1998-2000, 2002, 2004, 2006, 2009 and 2011] indicates a significant ‘stability’ of findings that suggests that these data do reliably represent the clinical status of individuals with diabetes attending specialist diabetes services in Australia {see Final Report-Pooled Data (December 2011) [Appendix 7]}.

Despite the overall ‘data stability’ noted above, and whilst these data are cross-sectional, and on different individuals from different sites in different years, it is interesting to note some differences which may reflect changes in clinical practice. These include [compared to 2009 data]:

  • 4.8% more individuals reported to be on Anti-hypertensive therapy;
  • 7.3% more individuals reported to be on Anti-lipid therapy.
Whilst these could indeed just be differences in clinical practice in different sites, it is interesting to speculate that over time, the changes [a gradual general increase], reflect changes in clinical practice resulting from the findings of studies such as the UKPDS which highlighted the importance of risk factor assessment and management, as well as blood glucose control, in the overall management of Type 2 diabetes.

Thus whilst no direct comparisons can be drawn from cross-sectional data on different individuals from different sites, the above observations do suggest that individuals attending specialist diabetes services are requiring more therapeutic interventions and are receiving increasing assessment and management of known risk factors in an attempt to maintain their health and prevent or delay complications.
