Abstract

Background: Identification of an organism is the gold standard for the diagnosis of fungal infection; however, we have previously shown that invasive procedures infrequently lead to a change in management in children with cancer or who have undergone stem cell transplant with suspected respiratory tract invasive fungal infection (RT-IFI). There is also a paucity of data on the cost of RT-IFI in this population. We therefore compared the costs of RT-IFI diagnosed based on CT scan alone versus those who underwent a bronchoalveolar lavage (BAL) or respiratory tract biopsy (RTB). Procedure: We collected cost data on patients at a single center undergoing chemotherapy or who were post-hematopoietic stem cell transplant (HSCT) and were suspected of having RT-IFI between 2007 and 2012. Cost data were included for 14 days from the day of their diagnostic CT scan or procedure. Results: Cost data were available for 76 patients. Thirty-six patients were diagnosed with suspected RT-IFI based on CT only, and 40 patients underwent BAL or RTB. Costs related to chest X-rays (CXRs), inpatient/intensive care unit (ICU) beds, anesthesia, operating room (OR) time, and procedures were significantly higher in the BAL/RTB group versus CT scan group (all P < 0.01). Costs related to CT scans were significantly higher in the CT scan group (P = 0.0002). Overall costs were significantly higher for patients who underwent BAL or RTB versus CT scan only (P < 0.0001). Conclusion: Our previous data showed that BAL and RTB infrequently led to a change in management in this population. We now demonstrate that this strategy is costly as well.
