Implementation of Pharmacist-driven Antifungal Stewardship Program in A Tertiary Care Hospital
Objectives: Antifungal stewardship (AFS) is recommended to reduce the inappropriate use of antifungal drugs. In this study, the role of AFS in providing appropriate antifungal therapy was evaluated. Methods: This study included three periods as observation, feedback/education, and daily AFS activities. In observation period, the use of systemic antifungals was evaluated for a baseline measurement of appropriateness. In second period, monthly meetings were organized to provide feedback and education to physicians regarding antifungal therapy and the rate of adherence to the clinical guidelines. In final period, a clinical pharmacist participated in daily ward rounds to evaluate appropriateness of the antifungal therapy. A scoring system for appropriateness was used for comparison between the three periods. Results: Four hundred and eighteen episodes of antifungal therapy were evaluated. Baseline demographics of patients were similar in all three periods for age, gender, and the number of comorbidities. The indications for antifungal use were for prophylaxis in 22.7%, Candida infections in 58.6%, and invasive mould infections in 18.7%. During the third period, 157 (78.9%) recommendations were made and 151 (96.2%) were accepted. The overall appropriateness of antifungal use increased significantly for prophylaxis (30.8%, 17.9%, 46.3%, p=0.046) and treatment of fungal diseases (27.8%, 32.4%, 71.9%, p<0.001) between the first, second and third periods, respectively. A 30-day mortality was not significantly changed between the three periods (19%, 15.6% and 27.5%; p=0.050). Conclusions: Appropriateness in antifungal therapy can be augmented by the integration of an AFS program. A team-based evaluation of fungal infections and assessment of patients by a clinical pharmacist with a therapeutic perspective may help to increase the quality of antifungal therapy.
