To determine the effectiveness of using antifungal therapy in conjunction with the diagnostic driven approach (DDA) in the management of invasive fungal infection (IFI) among patients undergoing allogeneic bone marrow transplantation (BMT)
Two strategies, DDA and antifungal prophylaxis, were used to diagnose and treat early IFI among allogeneic BMT patients. Two segments of 20 months included a preimplementation period in which medical records and laboratory statistics were used from admission up to six months. The intervention was the implementation of a DDA and the provision of antifungal prophylaxis. Prior to implementation, no routine antifungal prophylaxis was administered and the diagnosis of IFI was based on European Organization for Research and Treatment of Cancer (EORTC) criteria, including galactomannan assays. Antifungal agents were administered based on assay results. With the implementation of a new protocol, antifungal prophylaxis was given to those with graft-versus-host disease (GVHD), those treated with corticosteroid therapy, those with severe aplastic anemia, those undergoing cord blood transplantation, and those in which the standard diagnostic workup was deemed to be less effective. All patients were managed in high-efficiency particulate air (HEPA)-filtered rooms and housed in areas with limited access.
A significant reduction in the cases of IFI (p = 0.051) was observed overall. The incidence of mold infection (aspergillosis) decreased substantially in the protocol period (p = 0.054). However, no change was noted in the survival rates and breakthrough fungal infection in the pre and post intervention phases.
The implementation of a clinical management protocol helped diagnose and treat early fungal infection and was associated with an overall reduction in the incidence of IFI.
Nursing role is vital in identifying the key sign and symptoms of infection and to highlight them to decrease the rates of fungal infections, hence minimizing the mortality and morbidity rates overall. This study demonstrated that a standardized approach to prophylaxis was associated with reduced fungal infections.
