A soothing voice in the ICU: could positive suggestions curb Post-Intensive care anxiety?
NCT ID NCT04045210
First seen Aug 21, 2026 ยท Last updated Aug 21, 2026
Summary
This trial tests whether daily psychological support based on positive suggestions, delivered by trained ICU doulas, can reduce anxiety and depression in critically ill adults. Participants are patients on breathing support who are expected to stay in the ICU for more than 48 hours. Half receive the supportive intervention alongside standard care, while the other half receives standard care alone. The study measures mental health outcomes shortly after ICU discharge and again at six months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Psychological support based on positive suggestions delivered by ICU doulas
- What this could lead to
- If effective, this approach could offer a simple, drug-free way to reduce anxiety and depression in critically ill patients during and after an ICU stay.
- What could go wrong
- The trial is relatively small and the intervention is subjective, so results may vary. It also depends on the skill of the doulas and may not work for everyone.
