Risk Stratification Using Midregional Proadrenomedullin in the ED

IDEntifying pAtients With Suspicion of Infection in the ED Who Have Low Disease Severity Using Midregional Proadrenomedullin (MR-proADM) - Pivotal Study

Emergency departments (ED) are becoming increasingly over-crowded, with patients facing prolonged waiting times. Therefore, a safe and rapid assessment that identifies patients with low severity that could be treated as outpatients is essential for improving the workflow within the ED.

The rationale of this IDEAL+ study is to safely decrease the number of hospital admissions through identification of low risk patients with the biomarker MR-proADM. This will has already been tested in the IDEAL - pilot study and results should be confirmed with this IDEAL+ study.
