INTRODUCTION: Foot ulcer is also a clinical marker for limb amputation and for
death in diabetic patients. The purpose of this study was to determine amputation
and mortality rates and its associated factors in patients with diabetic foot
ulcerations in a tertiary hospital in Brazil.
METHODS: Retrospective medical records from 654 diabetic foot patients were
reviewed. The risk factors were determined using the conditional logistic
regression model analysis.
RESULTS: The mean patient age was 63.1 years (SD 12.20). Peripheral arterial
disease was present in 160 patients (24.5%). Major amputations were performed in
135 (21%). The in-hospital mortality rate was 12% and the mortality rate of the
amputees was 22.2%. The lowest hemoglobin level, the median value was 9.50g/dL,
(4.0-17.0). Anemia was detected in 89.6% of patients submitted to amputation and
in 82,1% of those who died. Hemoglobin <11g/dL was the most significant risk
factor for major amputation (odds ratio 5.57, p<0.0001). The presence of
peripheral arterial disease and old age were also a risk for major amputation
(odds ratio 1.84, p=0.007 and 1.02, p=0.028, respectively). Factors associated
with increased risk for death were hemoglobin <11g/dL (odds ratio 4.04, p<0.001),
major amputation (1.79, p=0.03) and old age (1.05, p<0,001).
CONCLUSIONS: Diabetic foot ulcer is associated with high amputation and mortality
rates. Old age, peripheral arterial disease and low hemoglobin level are risk
factor for major amputation. Old age, major amputation and low hemoglobin level
are risk factors for death.
