Patients and Methods
In end of June 2016, 5 out of 6 Greek PHO units and the country’s single pediatric BMT unit participated in this collaborative, and prospectively recorded the first 15 children per month admitted to their units, who required the initiation of new antibiotics for treatment or prophylaxis. Ethics approval was obtained from the institutional review boards of all participating hospitals. Individual informed consent was not considered necessary to be obtained in any of the hospitals.
