Hospital-wide antifungal prescription in Greek hospitals: a multicenter repeated point-prevalence study

Abstract

The aim of the study was to evaluate antifungal prescriptions among hospitalized adult patients in Greek hospitals. This multicenter two-times, 1-day, point-prevalence study was carried out in 2015 and 2017 in five and six hospitals, respectively. Among the 5812 patients screened in both periods, antifungals were prescribed in 129 patients (73 in 2015 and 56 in 2017); antifungals were used as prophylaxis in 31 patients (24%), pre-emptively in 32 (25%), empirically in 38 (30%), and as targeted therapy in 28 (22%). Triazoles were the class most commonly used (65 patients; 50%), followed by echinocandins (59; 46%) and liposomal amphotericin B (12; 9%). The use of echinocandins was higher (P 0.009) in the ICU (16 out of 22 patients), as compared with those in other departments (40%). Antifungal treatment was deemed inappropriate in 32/129 patients (25%) (16% in 2015 versus 36% in 2017; P 0.014). Inappropriate antifungal administration was more common if indicated by the primary physician, as compared with an infectious disease specialist (35% versus 5%; P < 0.001). Candidemia represented the majority of microbiologically documented infections (12 out of 28). Only two cases of proven pulmonary aspergillosis were diagnosed. Fluconazole and echinocandins were most frequently prescribed for identified or presumptive fungal infections, while fluconazole or posaconazole was given most frequently as prophylaxis. Antifungal treatment has been, ultimately, proven unnecessary in one-fourth of cases, underlining the need of a nationwide antifungal stewardship program.
