2114. Correlation Between Antifungal Consumption and the Distribution of Candida Species in a Hospital in Colombia

BACKGROUND: In recent years, a shift toward non albicans Candida infections has been described. An increase in the prescription of antifungals has been attributed as the cause of this change, but this issue has not been evaluated in Colombia. METHODS: The distribution of Candida spp. over an 11-year period 2007–2018 were extracted of the software WHONET 5.6. Antifungal drug consumption was measured as the number of defined daily doses (DDD)/100 patient-days over a 6-year period 2012–2018. Spearman’s coefficient was performed to find a correlation between antifungal consumption and distribution of Candida species. RESULTS: A total of 811 non-duplicate isolates of Candida spp. were included. An increase in the frequency of isolates was observed in the period 2013–2016 (Figure 1). The highest number of isolates were collected from the intensive care unit (ICU) (35.6%) followed of medical ward (22%). Non albicans Candida predominated (58%) in the period evaluated. The shift toward non albicans Candida was presented in 2015 (Figure 2). A non-homologous distribution of albicans vs. non-albicans was noted between ICU and general ward (P = 0.026). 152 (18.7%) isolates were recovered from blood. C. parapsilosis was the most commonly species identified in the blood cultures of ICU in contrast to C. albicans in general ward (Figures 3 and 4). Intravenous fluconazole was the main antifungal prescribed in ICU (mean 0.094 DDD/100 PD). Oral fluconazole was the principal antifungal prescribed in a medical-surgery ward (mean 0.021 DDD/100 PD) and oncology unit (mean 0.429DDD/100 PD). None of the correlations between antifungal consumption and recovery of non albicans species reached a statistical significance. CONCLUSION: The shift toward non albicans Candida is possible even in the presence of a low consumption of antifungals. This finding suggests the possibility of other contributing factors such as cross transmission and microbiome alteration.
