Evaluation of empirical antibiotic use in diabetic foot infections at a tertiary hospital in Vietnam: A retrospective study.

Empirical antibiotic prescription guidelines were developed at the University Medical Center Ho Chi Minh City in 2020, which included recommendations for the use of antibiotics to treat diabetic foot infections (DFIs). This study investigated the treatment outcomes when implementing empirical antibiotic guidelines. This retrospective study included 120 inpatients with DFIs at the Department of Endocrinology, University Medical Center Ho Chi Minh City. This study had 2 periods (before and after implementation of hospital antibiotic guidelines): Period 1 from July 2019 to June 2020 and Period 2 from July 2021 to June 2022, with 60 random patients in each period. Treatment outcomes were assessed as follows: improvement (defined as the absence of fever and a white blood cell count within the normal range) at 72 hours and 7 days; duration of hospitalization; and clinical status at hospital discharge. After implementing empirical antibiotic guidelines, a greater proportion of improvement in the first 7 days of hospitalization (75.0% vs 56.7%, P = .03), and a shorter median duration of hospitalization (12.5 days vs 15.0 days, P = .02) were observed in patients with DFIs. All the patients showed improvement at the time of hospital discharge. The study findings revealed the encouraging effects of implementing empirical antibiotic prescription guidelines for DFI treatment.
