[Operative treatment of diabetics with vascular complications : Secondary data analysis of diagnosis-related groups statistics from 2005 to 2014 in Germany].

BACKGROUND

In Germany approximately 40,000 amputations per year are performed on patients with diabetes mellitus, often with accompanying vascular complications.

OBJECTIVE

The aim of this study was to present the various degrees of severity of the vascular complications and the temporal changes of the treatment options in diabetics with vascular complications in Germany.

MATERIAL AND METHODS

The microdata of the diagnosis-related groups (DRG) statistics of the Federal Statistical Office were analyzed over the period from 2005 to 2014. All cases were included in which the main or secondary diagnosis of diabetes mellitus with concurrent vascular complications (diabetic angiopathy and peripheral arterial disease) was encrypted.

RESULTS

The median age of the 1,811,422 cases was 73 years and 62% were male. While the total number of amputations remained stable over time, there was a 41% reduction in knee-preserving and a 31% reduction in non-knee preserving major amputations with an 18% increase in minor amputations. Revascularization increased by 33% from 36 procedures in 2005 to 48 procedures per 100,000 inhabitants. The increase in revascularization was evident in the area of endovascular therapy alone where there was an increase of 78%.

CONCLUSION

Due to the significant increase in endovascular revascularization measures, there was a significant increase in the proportion of diabetes patients with vascular pathologies in whom revascularization was carried out. As a result, improved limb preservation was achieved despite equally high amputation rates due to increasing minor amputation rates.
