Pathologist assistants plus AI triage to multiply pathologist capacity
Much of a pathologist's day is preparation, measuring and describing specimens. Trained assistants can do that, and AI can pre-screen slides, so each pathologist reports far more cancers.
Pathologists' assistants (a recognised profession in North America) perform gross examination and dissection, while AI tools can pre-screen slides for likely malignancy and prioritise them. Together these could double the throughput of a pathologist without lowering quality. Most health systems have neither role nor tool in routine use. The proposal is a combined workforce-and-technology package with a training route for assistants and validated AI triage.
Hypothesis
Laboratories deploying assistants and AI triage will increase cancers reported per pathologist-hour by at least 80% and reduce median turnaround time by a third, with no increase in major discrepancies on audit.
Rationale
Grossing and screening are the time-consuming, protocol-driven parts of pathology; AI triage has shown high sensitivity in prostate and lymph node screening tasks.
What would test it
A controlled implementation in four laboratories with time-motion, turnaround, and discrepancy-rate measurement against matched laboratories.

Bottlenecks it attacks
- Not enough oncologists, nurses, pathologists, physicists · The number of people with cancer is rising faster than the workforce trained to treat them.
- AI that is built but not validated or deployed · Thousands of cancer AI models are published; a handful are in clinical use, and fewer have shown they help patients.
