Conditions

Critically ill patients with suspected fungal infection or proven fungal infection Infections and Infestations Critically ill patients with suspected fungal infection

Interventions

The A-STOP Study is a multi-centre, prospective, diagnostic test accuracy study. The purpose of this project is to assess the performance of three rapid tests for fungal infection. The accuracy of the

Design outcomes

Primary

MeasureTime frame
Accuracy is measured using the negative predictive value for each index test

Secondary

MeasureTime frame
1. Measures of diagnostic test accuracy, for each test alone and in combination, based on an international consensus reference standard for proven invasive fungal disease, applied for Candida infection. These will comprise sensitivity, specificity, positive/negative predictive values and positive/negative likelihood ratios. 2. Measures of diagnostic test accuracy, for each test alone and in combination, based on an international consensus reference standard for proven and probable invasive fungal disease, applied for Candida infection. 3. Estimated proportion of patients receiving systemic antifungal therapy in this cohort for whom treatment is unnecessary, derived from the reference standards used. Estimated number of days’ avoidable antifungal treatment if negative index test results were used to stop treatment. 4. Development of a test-based protocol using the index tests (alone or in combination), as a strategy for early cessation of empirical antifungal treatment, with assessment of its expected cost-effectiveness modelled on test accuracy, disease prevalence and clinical/economic outcomes in this patient group.
