Improving recovery from anemia after intensive care

Anaemia Management With Red Blood Cell Transfusion to Improve Post-intensive Care Disability: a Randomised Controlled Trial (The ABC Post-intensive Care Trial)

Not applicable Interventional University of Edinburgh · NCT04591574

This study tests if giving red blood cell transfusions to patients with severe anemia after leaving the ICU can help them recover better than the usual treatment.

What this trial studies

This trial investigates whether treating severely anemic patients with red blood cell transfusions after their discharge from intensive care can improve their health outcomes. It compares the current restrictive transfusion approach with a more active regimen aimed at correcting anemia. The study will take place in acute hospitals across the UK, focusing on patients who have recently been discharged from the ICU and have low hemoglobin levels. Eligible participants will be approached for consent during their hospital stay.

Who should consider this trial

Good fit: Ideal candidates are patients aged 16 and older who have received level 3 ICU care and have a hemoglobin level of 94g/L or lower upon readiness for discharge.

Not a fit: Patients who are actively bleeding, have contraindications to transfusion, or are receiving end-of-life care may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly enhance recovery and quality of life for patients who have experienced severe anemia after intensive care.

How similar studies have performed: While this approach is novel in the context of post-ICU anemia management, similar transfusion strategies have shown promise in other settings.
