Diagnosis and Management of Invasive Fungal Wound Infections in Burn Patients

Invasive fungal wound infection (FWI) after burn injury, while uncommon, is associated with significant morbidity and mortality. There are numerous risk factors for FWI, including large burn size and incomplete excision of burn wounds. FWI can be challenging to diagnose. Close attention to changes in the physical examination and, in particular, to the appearance of burn wounds leads the burn team to be suspicious of FWI. Once FWI is suspected, histopathological evaluation of an incisional biopsy provides definitive diagnosis, while tissue culture enables identification of the causative organism to the species level and facilitates targeted antifungal therapy. Management of FWI focuses largely on aggressive surgical intervention, in addition to adjunctive systemic and topical antifungals and nonpharmacologic therapies. Treatment of FWI involves a multifaceted approach, which requires expertise from the entire multidisciplinary burn team.
