Introduction:

In the Colombian Caribbean region, there is scarce evidence on diabetic foot infection to support decision making based on the patient's own data, and the current microbiological behavior of this type of infection is unknown.

Methods:

Cross-sectional study that included patients with diabetic foot infection treated at a third level referral hospital in the Colombian Caribbean region, between September 2021 and May 2022. Sociodemographic, clinical and microbiological data on the patient and his infection were extracted. A descriptive analysis and prevalence ratio (PR) calculation were performed to identify factors associated with unfavorable outcomes.

Results:

A total of 149 patients were included. The 61.8% of the sample was male, with a median age of 61 years. Moderate to severe infection predominated (67.8 %). Pseudomona aeruginosa (18.1 %), Escherichia coli (13.5 %), and Staphylococcus aureus (12.8 %) were the most frequent agents found. 44.2 % of the microorganisms showed resistance. Smoking (p <0.001), history of amputation (p <0.001), chronicity of ulcer (p <0.001) and admission to intensive care (p <0.001) were significantly associated with mortality, amputation, microbial resistance and diagnosis of osteomyelitis by imaging

Conclusions:

In the Colombian Caribbean region, diabetic foot infection is predominant in middle-aged men, with moderate to severe presentation, mainly caused by gram-negative bacteria and enterobacteria, and smoking and admission to intensive care are the factors most significantly associated with unfavorable outcomes.
