CONCLUSION
In this study, we performed surveillance of antibiotic prescribing practices in hospitalized children with cancer and HSCT recipients in Greece. Our surveillance data allowed comparisons among units, identified areas necessitating improvement and provided useful information on antibiotic prescribing to physicians in each PHO unit. As a next step, an active intervention with designated antibiotic stewardship physicians and prospective audit and feedback recommendations at each Greek PHO unit is needed. Ideally, future accurate capturing of unit-specific antibiotic susceptibility data for all bacterial pathogens is needed along with more dedicated personnel exclusively involved with antibiotic stewardship. Finally, further research in this area is required to reduce the use of broad-spectrum antimicrobials and antifungals safely and substantially in this susceptible patient population.
