753. Guideline Adherence Predicts Outcomes of Candidemia in Europe: Results from the ECMM Candida III Multinational European study

BACKGROUND: The European Confederation of Medical Mycology (ECMM) collected data on epidemiology, risk factors, treatment, and outcomes of culture proven candidemia across Europe in order to assess how adherence to guideline recommendations correlate with outcomes. METHODS: Each participating hospital (number of eligible hospitals per country determined by population size) included the first ∼10 culture proven IC cases after 01-Jul-18 and entered data into the ECMM Candida III database on the FungiScope™ platform. EQUAL Candida Scores (10.1111/myc.12746) reflecting adherence to recommendations of IDSA and ESCMID Guidelines were assessed. RESULTS: A total of 632 Candidemia cases were included from 64 institutions in 20 European countries. Patients characteristics are displayed in Table 1. Overall mortality was 45% (286/632), and hospital stay was prolonged (median 2 days) for completion of parenteral therapy only in 16% (100/621) of patients. EQUAL Candida Score was evaluable for 589 cases with candidemia (Figure 1). Candida scores correlated significantly with duration of hospitalization (r= 0.442; p< 0.001) and - after exclusion of patients hospitalized < 7 days (n=119) - were significantly higher in patients who survived versus those who died (p< 0.001). Duration of hospitalization was in median 16 days after diagnosis of candidemia. Initial echinocandin treatment was associated a.) with lower overall mortality (42%, 148/353) versus those without initial echinocandin therapy (53%, 126/236; p=0.007), and b.) with longer duration of hospitalization among survivors (median 24 days, IQR 15–40 days vs. median 16 days, IQR 7–33 days; p< 0.001). In those where candidemia was treated for at least 14 days, 78% (239/306) survived, compared to 66% (67/102) in those treated for less than 14 days, but who survived beyond day 14 after diagnosis. [Figure: see text] [Figure: see text] CONCLUSION: Initial echinocandin treatment was associated with increased overall survival, but also longer duration of hospitalization (hospitalization was prolonged only for completing treatment in 16%). Overall mortality of IC was 45%. EQUAL Candida scores were significantly higher on those who survived, indicating that adherence to clinical guidelines may increase survival.
