Effect of an intervention to improve the prescription of antifungals in pediatric hematology-oncology

Background The use of antifungals has expanded in pediatric hematology-oncology, and the need to develop pediatric-based surveillance and education activities is becoming crucial. The aims of this study were to evaluate the impact of a multidisciplinary protocol on the adequacy of antifungal prescription in a pediatric hematology-oncology unit and to assess the effect of an educational intervention to improve the knowledge of prescribing pediatricians over time. Methods A multidisciplinary team established a protocol for the management of invasive fungal disease (IFD). The use of antifungals before (January 2012-May 2013) and after the protocol (June 2013-December 2015) was evaluated. Prescribing pediatricians attended a training course on IFD and were evaluated before 0, 6, and 12 months after the intervention. Results During the study period, antifungal agents were used in 185 episodes (56 children, 39.3% females), and were administered as prophylaxis (58.9%), empiric (34.6%), or targeted therapy (6.5%). Antifungal prescriptions were inadequate in 7% of the episodes, related to drug selection (53.8%), dosage (38.5%) and route of administration (7.7%). After protocol implementation, inadequate prescriptions decreased 9.9% (15.2% vs 5.3%; P = .04). Following the educational activity, the percentage of adequate responses to the questionnaire improved significantly compared to baseline, and persisted over time (19.7% improvement at 0 months [P P P = .002]). Conclusions The establishment of multidisciplinary protocols and education activities improved the quality of antifungal prescription and the knowledge of prescribers regarding antifungal therapy. Therefore, these activities may be important for the implementation of antifungal stewardship programs in pediatrics.
