Australian National Diabetes Information Audit & Benchmarking (ANDIAB) 2011 Final Report

2.4.1 Blood Glucose Control

Data on Blood Glucose control, relating to Glycated Haemoglobin result and upper limit of normal range

Page last updated: December 2011

Recorded

Most recent/current Glycated Haemoglobin Result [HbA1c (%)] in the last 12 months, and Upper Limit of Normal Range [ULN] (%).

% Missing (Overall)

Glycated Haemoglobin Result 8.3%;
Upper Limit of Normal Range 0%.

This meant that in 91.7% of records, a Glycated Haemoglobin result and Range ULN were available for analysis.

Results

[1] Mean SD:
Table 9 gives overall results for Glycated Haemoglobin for the Total Group. See Frequency Tables for n= and range data

[2] Glycated Haemoglobin Result relative to ULN Range :
Table 10 gives overall results for Glycated Haemoglobin relative to ULN
Table 10[a] gives Type 1 results for Glycated Haemoglobin mean and relative to ULN Range for that result. See Frequency Tables for n= and range data.

Tables on Pages 93-100 of Appendix 5 show the breakdown for Mean HbA1c by Diabetes Type for all data, thence Target HbA1c. The Graphs show the spread/comparison of site’s results ranked in order for totals and broken down by Diabetes Type.
The pages are All Sites Data which in 2011 is all Adult Forms Data.
