Diagnosis, clinical features and survival analysis of invasive pulmonary aspergillosis among critically ill patients: a retrospective cohort study based on updated criteria

IPA is a common and lethal complication in ICU pneumonia patients, serving as an independent predictor of mortality. BALF GM, particularly when integrated with molecular testing, is the most effective mycological diagnostic method. Reducing the diagnostic window, initiating timely antifungal therapy, and proactive airway management (e.g., tracheostomy) may significantly improve clinical outcome for these critically ill patients.
