[HbA1c-mapping--evaluation of a new method for population-based monitoring of metabolic control in patients with diabetes mellitus].
OBJECTIVE
The purpose of this study was to analyse metabolic control in patients with diabetes mellitus in primary care in Thuringia and to evaluate HbA1c mapping as a newly proposed method for population-based continuous monitoring of metabolic control in primary care.


METHODS
A cross-sectional study (2nd quarter 2005) using the electronic data bases of Thuringian medical laboratories (HbA1c, postal code of GP) was undertaken. The study population comprised all Thuringian patients with diabetes mellitus who were treated in ambulatory care. A comparison was made between data from HbA1c mapping and data collected by GPs (general practitioner) of two selected areas.


RESULTS
We collected 89,407 HbA1c tests by HbA1c mapping: the following values were obtained - mean HbA1c: 6.73+/-1.27%; HbA1c >/=7%: 32.6%; HbA1c >/=10%: 2.4% of all HbA1c tests. The mean HbA1c was 0.2% lower in HbA1c mapping compared to data collection in GPs (HbA1c 6.8+/-1.32% vs. 7.02+/-1.26%, p<0.001). The percentage of HbA1c tests below 7% was higher, HbA1c test results between 7% and 9% were less frequent in HbA1c mapping. Patient data were as follows: type 2 diabetes 98.7%, female gender: 57%, age 69.8+/-11.6 years, insulin therapy 28.8%.


CONCLUSIONS
The Thuringian cross-sectional study 2005 showed acceptable results for metabolic control in ambulatory care. The results of HbA1c mapping were comparable to the data on glycaemic control of patients with diabetes mellitus in ambulatory care.
