Objectives: This study examined the burden of hospitalization of patients with Aspergillus and Candida infections in Australia from 1995 to 1999.
Methods: Data were extracted from the National Hospital Morbidity Database. A hospitalization with an aspergillosis diagnosis was defined as any discharge with a diagnosis of aspergillosis. A hospitalization with a candidiasis diagnosis was defined as any discharge with a diagnosis of disseminated, invasive, or non-invasive candidiasis. Outcome measures included number of hospitalizations, length of stay (LOS), cost (AUS$), and mortality.
Results: 4583 hospitalizations with an aspergillosis diagnosis and 57,758 hospitalizations with a candidiasis diagnosis were identified. These hospitalizations were associated with a total of 813,398 hospital days, AUS$563 million in cost, and 4967 in-hospital deaths during the study period. The mean LOS for a hospitalization with an aspergillosis diagnosis was 12 days, cost AUS$9,334, and was associated with 8% mortality. For disseminated, invasive, and non-invasive candidiasis, the respective mean LOS were 31, 17, and 12 days; costs were AUS$33,274, AUS$12,954, and AUS$7,694; and mortality was 26%, 9%, and 8%.
Conclusions: Hospitalizations with diagnoses for fungal infections were associated with lengthy hospital stays, high costs, and high mortality.
