Abstract

Background: Invasive fungal diseases (IFD) are life-threatening and demand timely and appropriate treatment. Research showed that isavuconazole treatment positively affects clinical outcome and length of hospital stay (LOS).

Objectives: The aim of this study was to assess the hospital costs of patients diagnosed with IFD and treated with isavuconazole using real-world data from a German cancer centre.

Patients/methods: Data and LOS collected from Jan-2016 to Jun-2021 at Department I of Internal Medicine, University Hospital Cologne were retrieved. Case-related resources consumed during the hospital stay across isavuconazole routes of administration (oral, parenteral, and mixed administration) were identified, quantified, valued and compared via a cost analysis that adopted the healthcare payer perspective.

Results: In total, 101 cases with isavuconazole treatment were identified (oral: n = 22, 21.8%; parenteral: n = 59, 58.4%; mixed: n = 20, 19.8%). Median total LOS was greater in the mixed group (46.5 days; p = .009). Median ICU LOS and ventilation duration were both longest in the parenteral-only group (16 days, p = .008; 224 h, p = .003). Invasive aspergillosis was the most frequent isavuconazole indication (n = 86, 85.2%). Average hospital costs were highest in the mixed group (€ 101,226). The median overall costs of cases treated with isavuconazole was € 52,050.

Conclusions: Treating IFD is resource intensive, often requires intensive care and implies high rates of in-hospital mortality. Our study emphasises the high hospital treatment costs and thus the need for reimbursement systems to enable live-saving costly treatments.
