## TL;DR

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

## Summary

There are far too few genetic counsellors, so this idea uses validated language-model counselling assistants with safety guardrails for standard pre-test education in population and cascade testing, leaving people with complex needs for human counsellors. The BRIDGE trial showed chatbot pre-test education was non-inferior to counsellor delivery for testing uptake, and workforce is the rate-limiter for expanding germline testing. The aim is non-inferior knowledge and decisional conflict scores with several times the throughput per counsellor. The test is a non-inferiority RCT in 2,000 patients. At early-clinical maturity it addresses the bottlenecks Inherited risk is mostly unidentified and Not enough oncologists, nurses, pathologists, physicists.
