Using D-dimer to improve patient discharge in emergency departments

Use of D-dimers in the Emergency Department to Identify Adult Patients at Very Low Risk of Mortality for Fast-track Treatment - a Randomized Controlled Study

Not applicable Interventional Odense University Hospital · NCT06219486

This study tests if checking D-dimer levels can help doctors quickly identify low-risk patients in emergency departments who don't need to stay in the hospital.

What this trial studies

This study aims to evaluate the use of D-dimer levels to identify low-risk patients in emergency departments who may not require hospitalization. By conducting a multicenter randomized controlled trial, the researchers will assess whether providing D-dimer results influences the time to discharge disposition by physicians. The study focuses on patients with non-specific complaints who are stable upon arrival and have normal vital signs. The goal is to streamline patient care and reduce unnecessary hospital admissions.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and above who present with non-specific complaints and have stable vital signs.

Not a fit: Patients with unstable conditions requiring immediate care or those classified as triage level red will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to faster discharge times and more efficient use of emergency department resources.

How similar studies have performed: Previous studies have indicated that normal D-dimer levels correlate with low risk of significant disease, suggesting potential success for this approach.
