New online tool aims to help cities beat the heat
NCT ID NCT06971978
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This pilot trial tests an online decision support tool called Chart that helps local health departments assess heat-health risks and plan for extreme heat events. Thirty health departments will either use Chart or receive standard heat-health information. The study measures how well the tool improves planning and identifies barriers to its use.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Online decision support platform (Chart)
- What this could lead to
- If successful, this tool could help local health departments better protect communities during extreme heat events by identifying local risks and effective interventions.
- What could go wrong
- This is a small pilot trial with only 30 participants, so results may not apply broadly. The tool's impact depends on how well health departments adopt and use it.
