Abstract
Introduction: Diabetic foot ulceration (DFU) is associated with high morbidity, mortality, and represents the
leading cause of hospitalization in patients with diabetes. Peripheral arterial disease (PAD), present in half
of patients with DFU, is an independent predictor of lower limb amputation (LLA) and can be difficult to
diagnose in a diabetic population. Underdiagnosis and undertreatment of critical PAD are frequent.1-3 To our
knowledge there is no data about LLA incidence in Croatia neither in diabetics nor in nondiabetics. Our aim
was to determine the incidence of amputation in patients with diabetes mellitus in Osijek-Baranja County.
Patients and Methods: This was a tertiary-care-based retrospective study involving adult patients in
whom amputation were performed for reasons relating to complication of PAD and/or diabetes in the
University Hospital Centre Osijek from 1st January 2008 to 31st December 2018. We calculated LLA rates
using estimates of the population with diabetes derived from CroDiab registry and Croatian Institute
for Public Health for Osijek-Baranja County. LLAs were further categorized by level of amputation as
follows: minor (toe and foot) and major (above foot and below knee, and above knee).
Results: There were 1551 LLAs in ten-year period. Smaller proportion of amputation was above foot
(49.3% vs 59.3%). LLA rates per 1,000 adults with diabetes decreased 29% between 2010 and 2013 and
then increased 76 % between 2014 and 2018 (Figure 1). We observed the same pattern in both minor and
major LLA but rates of amputation above knee steadily increased 2.65 times between 2010 and 2018
(from 0.69 to 1.83 LLA per 1,000 patients).
Conclusion: This study confirmed high rate of lower limb amputation in diabetic patients in Osijek-
Baranja County which is representative for east Croatia region. After a decline of low limb amputations in
diabetic patients between 2011 and 2013, LLA rates began to increase from 2014 to 2018. Reasons for that
reversal trend are unclear. It can be due to poor management of CVD risk factors, poor glycemic control,
and failure in early detection of PAD. It is also possible that change in health policy and organization of
diabetes care together with socioeconomic factors could affect trends of LLA. Incidence rate of LLA in
our population is important for further improvements in diabetes care and for decisions in health policy.
