Description of intervention(s) / exposure
Active comparator: Standard diagnostic strategy of culture and histology - The standard-diagnostic strategy was designed to be consistent with the 2002 guidelines for antimicrobial use in neutropenic patients with cancer. When an invasive fungal infection was suspected (e.g. persistent fevers) cultures of blood, urine, sputum (if available) and faeces (if clinically indicated), and HRCT scans of chest were performed. Bronchoscopy and biopsies were performed according to institutional protocols. Empiric antifungal therapy was recommended whilst undergoing these investigations and was continued, de-escalated to prophylaxis, or changed to treatment of invasive aspergillosis or other IFD according to test results.

Experimental: Aspergillus galactomannan and PCR directed - Results of once to twice weekly testing with Aspergillus galactomannan and PCR directed the timing of CT scan performance and whether antifungal therapy was given
