Study finds clinical data improves medical LLM clinic tasks, didactic data aids knowledge
Researchers compared medical large language models trained on varying mixes of didactic (textbook) and clinical (patient record) data. Token‑matched experiments showed an asymmetric transfer: adding clinical data raised performance on clinic‑oriented benchmarks while keeping knowledge‑intensive scores competitive, whereas didactic data mainly lifted knowledge‑intensive results.
Key points
- Clinical data improves performance on clinic‑oriented tasks while staying competitive on knowledge‑intensive tasks.
- Didactic data mainly boosts knowledge‑intensive tasks but adds little to clinical reasoning ability.
- Small amounts of clinical data yield most gains on EHR‑grounded tasks; optimal mix varies by task.
Error analysis revealed a “knowing‑doing” gap: better factual recall did not automatically translate into stronger clinical reasoning. The authors also noted that modest amounts of clinical data captured most of the gains on EHR‑grounded tasks, and that the ideal didactic‑to‑clinical ratio depends on the downstream task’s knowledge and reasoning demands.
