START Triage Trainer

What it does: START Triage Trainer is a web drill for adult mass-casualty triage. The user gets a scene briefing (a highway bus crash), then triages 15 patients one at a time under a five-minute scene timer, choosing green, yellow, red or black. At the end they see their score, time used, and over-triage and under-triage errors counted separately. A mistakes review explains each error at the exact START step where the reasoning went wrong, with a clinical teaching note. The correct answers are computed by the START algorithm from each patient’s findings, so the answer key cannot contradict the algorithm.

Who it’s for: Medical students, paramedics, and disaster volunteers who need to keep their triage skills sharp between rare real-world drills.

What I learned: I’m a physician and researcher who writes Python for data analysis, but I had never built a web app. I learned how a static web app is split into HTML (structure), CSS (appearance) and JavaScript (behavior), and why keeping the medical logic in its own file made it testable. I learned to guide a coding agent through a plan first: scope, PRD and spec before any code, then small build steps with a test and a commit after each. That kept the AI from drifting. I also deployed the app to GitHub Pages, so anyone can use it from a link.
