Abstract
OBJECTIVES: To utilize the Antifungal National Antimicrobial Prescribing Survey (Antifungal NAPS), a novel tool utilizing international consensus metrics for antifungal stewardship, to assess the quality of systemic antifungal prescribing in Australian hospitals, in order to identify quality improvement targets. METHODS: Participating hospitals were directed to audit all systemic antifungals or focus on a specific antifungal drug or class. Data entry into the Antifungal NAPS online portal occurred between October 2022 and June 2023. The data collection tool comprised patient details, reasons precluding use of antifungals, prescription details (guideline compliance, appropriateness, and reasons for inappropriate prescribing) and patient outcomes. Descriptive statistics were used to analyse the data. RESULTS: Eleven hospitals contributed data for 516 prescriptions for 438 patients. Of these, 77.1% of prescriptions were appropriate, with the highest appropriateness for prophylactic (189/222; 85.1%), followed by directed (105/130; 80.8%) and empirical therapy (104/164; 63.4%). Fluconazole was the most commonly prescribed agent, which had the lowest rate of appropriateness (132/209; 63.2%). The most common reasons for inappropriate prescribing were no antifungal required (35/105; 33.3%), incorrect dose or frequency (30/105; 28.6%) and incorrect duration (19/105; 18.1%). Compliance with guidelines was 73.6%. CONCLUSIONS: This study outlines the successful implementation of the Antifungal NAPS, a standardized electronic audit tool for the assessment of antifungal prescribing quality. Key areas for quality improvement identified were the overuse of empirical fluconazole for urinary tract and intra-abdominal infections, the importance of invasive fungal infection risk assessment to guide prophylaxis prescribing and greater infectious diseases and antifungal stewardship oversight of antifungal prescribing to guide optimal prescribing.
