Association between procalcitonin levels and duration of mechanical ventilation in COVID-19 patients

Background Patients diagnosed with COVID-19 frequently require mechanical ventilation. Knowledge of laboratory tests associated with the prolonged need for mechanical ventilation may guide resource allocation. We hypothesized that an elevated plasma procalcitonin level (>0.1 ng/ml) would be associated with the duration of invasive mechanical ventilation. Methods Patients diagnosed with COVID-19, who were admitted to any of our health system’s...
