A chatbot for pre-test genetic counselling so counsellors see only who needs them

There are far too few genetic counsellors. A validated chatbot can do the standard pre-test education, leaving people with complex needs for humans.

The BRIDGE trial showed chatbot pre-test education was non-inferior to counsellor delivery for testing uptake. Propose language-model-based counselling assistants with safety guardrails, validated against counsellor outcomes, deployed in population and cascade testing.

Hypothesis
Chatbot-delivered pre-test education achieves non-inferior knowledge and decisional conflict scores with at least five times the throughput per counsellor.
Rationale
Workforce is the rate-limiter for expanding germline testing.
What would test it
Run a non-inferiority RCT in 2,000 patients.
Maturity
early clinical
Who has to act
engineering
Cost to try
Small (under $1M)
Years to first evidence
