Impact of dedicated infectious disease teamwork on the treatment and prognosis of patients with diabetic foot infection

Abstract

ObjectiveThe aim was to develop and evaluate the impact of a new model in which the infectious disease (ID) physician and pharmacist work together to treat diabetic foot infections (DFIs). MethodsA quasi-experimental before–after study was conducted. The medical charts of inpatients with DFI admitted between April 1, 2017 and March 31, 2018 were reviewed retrospectively (control group, n = 30). Inpatients diagnosed with DFI between April 1, 2018 and March 31, 2019 were enrolled prospectively as the intervention group and received treatment through dedicated ID teamwork (intervention group, n = 35). ResultsThe distribution of infection severity and levels of metabolic criteria were similar in the two groups. Compared with the control group, the intervention group received adequate initial empirical treatment more frequently (96.8% vs 43.5%, p < 0.001) and had a shorter median duration of fever (1 day vs 7.5 days, p < 0.001). Rates of healing and relapse within 6 months were similar in the two groups, although the intervention group showed more sites of osteomyelitis (p = 0.036) and a higher percentage of polymicrobial infections (48.6% vs 10.0%, p = 0.001). ConclusionThe early and full participation of ID physicians and pharmacists in the treatment of DFI facilitated targeted antimicrobial treatment and improved patient outcomes.
