Antifungal Prescribing in European Pediatric Intensive Care Units: Results of a Multinational 3-Month Weekly Point-Prevalence Survey

Le résumé fourni par la source

BACKGROUND: Critically ill pediatric patients admitted to the pediatric intensive care unit (PICU) are highly vulnerable to infections, including invasive fungal diseases and antifungal agents are frequently prescribed. Little is known about antifungal usage in PICUs across Europe. METHODS: A multinational 3-month weekly point-prevalence study for measuring antifungal drug use was organized. Eigtheen PICUs (16 hospitals) in 10 countries in the European region participated. All patients hospitalized in the participating PICUs and receiving systemic antifungals were included. Information about ward demographics was collected once; weekly ward and patient data were collected prospectively for the 12-week study period and entered in REDCap database. RESULTS: Among 18 PICUs, 8 (44%) followed prophylactic practices for targeted group of patients, 7/18 (39%) had an antifungal stewardship program and the majority (16/18, 89%) had the capacity of biomarker utilization (16/16 galactomannan, 13/16 beta-D-glucan, and 9/16 pan-fungal PCR). One hundred one courses in equal number of patients were recorded; 14 for patients aged <3 month, 87 for patients ≥3 month. Malignancy was the most common underlying condition among patients aged ≥3 month (29%) followed by surgery/trauma (25%), whereas all patients <3 month had undergone a recent surgery. Indication for antifungal prescribing was prophylaxis in 38% and treatment in 62% [empirical (57%), preemptive (13%), and targeted (30%)]. Fluconazole was the most common agent both for prophylaxis and treatment, whereas liposomal amphotericin B was the most frequent agent for targeted treatment. The majority (63%) of patients on prophylaxis were oncology or transplant patients. Common reasons for empirical and targeted treatment were persistent fever/other signs of infections in high-risk patients (61%) and Candida infections (100%), respectively. For targeted treatment, the most frequent pathogens were Candida albicans (37%) and Candida parapsilosis (32%). CONCLUSIONS: Most antifungal prescriptions across European PICUs were for treatment. Fluconazole was the most frequently prescribed antifungal. These surveillance data can guide antifungal stewardship strategies in PICUs.
