Outcome prediction using the Mortality in Emergency Department Sepsis score combined with procalcitonin for influenza patients.

Background: Severe influenza is often associated with bacterial coinfection and can trigger sepsis, which increases the severity, complexity and mortality of the disease. To determine an effective method for predicting 28-day mortality of emergency department (ED) patients with influenza, we investigated the Mortality in Emergency Department Sepsis (MEDS) score, procalcitonin (PCT) and other relevant biomarkers.

Methods: We conducted a retrospective, observational, monocentric study, and the endpoint was 28-day mortality.
