=== Challenges ===

* '''Simplicity is everything:''' If the questionnaire takes more than 3 minutes, patients won't do it. Must be dead simple.
* '''GP trust:''' GPs will ignore AI triage suggestions if they're wrong 20% of the time. Need very high accuracy for the specific triage use case (not general diagnosis).
* '''Babylon warning:''' Babylon raised $4B and collapsed. The lesson: AI triage in healthcare is harder than it looks, and overpromising kills trust. Must underpromise and overdeliver.
* '''Test pre-ordering:''' Getting labs to accept pre-orders from an app requires integration with lab systems. Not trivial.
* '''Regulatory:''' If the tool suggests specific tests, it's clinical decision support → potentially needs MDR certification.
