Current Standard

Conventional pulmonology practice relies on standard-of-care monitoring and existing regimens prior to this clinical case insight.

New Finding

During this period, he had been hospitalized 7 times at external institutions, where he underwent extensive investigations including fiberoptic bronchoscopy, endobronchial ultrasound-guided transbronchial needle aspiration, mediastinoscopy, thoracoscopy, and CT imaging-guided biopsy of a mediastinal mass.

Optimizing Sepsis Time Zero Definitions Through Associations between Antibiotic Timing and Mortality

Risk of death associations with antibiotics beyond 1 hour were most evident when sepsis time zero was defined by hypotension or lactate ≥4.0mmol/L, and with antibiotics beyond 3 hours when defined by acute respiratory failure. These findings could inform refinements to sepsis time zero definitions to better guide antibiotic urgency and performance measurement.
