New algorithm aims to end the pain of multiple needle sticks
NCT ID NCT05935228
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new decision-making tool that helps nurses assess how hard it will be to place an IV line. The tool scores patients based on vein visibility, size, and past difficulties, then suggests the best approach. Researchers hope this will reduce the number of needle sticks, pain, and complications for the 1 in 4 patients with difficult veins. The pilot will involve 794 adults in France and gather feedback from healthcare workers.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- A-DIVA Scale and algorithm (decision-making tool)
- What this could lead to
- If successful, this algorithm could help nurses place IV lines on the first try more often, reducing pain, bruising, and infections for patients with hard-to-find veins.
- What could go wrong
- This is a pilot study, so it is small and early. The algorithm may not improve outcomes in real-world settings, and results may not apply to all hospitals or patient groups.
