Abstract Title
Trend in LEA rates among T2DM patients managed in primary care clinics from 2012 to 2017



National Healthcare Group Corporate Office1, NHG Polyclinics2

Background & Hypothesis

Lower extremity amputation (LEA) is defined as the complete loss in the transverse anatomical plane of any part of the lower limb. For major LEA rates, Singapore is only below Israel and Slovenia among countries in Organization for Economic Co-operation and Development (OECD) in 2013.   The objective of this study is to look at the trend in LEA rates among Type 2 Diabetes Mellitus patients managed in primary care clinics over time.


All T2DM patients managed in publicly funded primary care clinics from 2012 to 2017 were included. The outcomes of interest were major and minor LEA rates in publicly funded tertiary hospitals within 1 year.


The number of T2DM patients seen has increased from 86,338 in 2012 to 115,997 in 2017. Despite this 35% increase in workload, 1-year major LEA rates has decreased from 0.082% in 2012 to 0.059% in 2017. However, 1-year minor LEA rates has increased from 0.120% in 2012 to 0.130% in 2017.

Discussion & Conclusion

We have seen a decreasing trend in major LEA rates among T2DM patients as limb salvage initiatives were implemented in these clinics. Further research is needed to look at the trend nationally and to further optimize the management of T2DM patients.
