Background: 85% of amputations in diabetic patients are preceded by the appearance of an ulcer. Reamputation rates of up to 60.7% at 5 years has been described, as well as mortality of up to 69.7% at one year for major amputations. Aim of the study is to characterize a population of diabetic patients, amputees due to infections associated with diabetic foot in a university hospital.
Material and methods: Inclusion and exclusion criteria and a sociodemographic, clinical and microbiological data collection format were applied to all amputations related to infections associated with diabetic foot between 2014 and 2016. Means and standard deviations and / or medians and percentiles were used.
Results: The average age was 61.6 years. Male sex and poor glycemic control and a high number of comorbidities such as hypertension and chronic kidney disease predominated. 24.4% of previous ulcers and 18.1% previous amputations. Major amputations were 39%. Stump infection was 23.6% and reamputations 24.5%. Mortality was 4.54%
Discussion: Poor metabolic control was identified, as well as a high percentage of comorbidities and complications. Insufficient nutritional follow-up and staging of vascular status with underreporting of relevant data such as neuropathy, deformities and status of the contralateral foot. The number of ulcers and previous amputations was high. There was good clinical / laboratory correlation. Initial major amputations were more frequent in women. There is a high percentage of surgical site infections and reamputations.
