KnowBench: Evaluating clinical AI with effort reduction
Researchers have introduced KnowBench, a new benchmark for clinical AI that uses Effort Reduction as a unified metric to measure the proportion of system-generated work accepted by clinicians. The benchmark is designed to be deployment-grounded, ensuring that evaluations reflect real-world burden reduction rather than mere similarity to reference artifacts. Initial results from a production environment show that Knowtex's clinical foundation models achieved an aggregate Effort Reduction of 97.99% across over one million signed encounters.
- ▪KnowBench defines Effort Reduction as the proportion of clinical work product accepted by the responsible clinician under expert and safety review.
- ▪The benchmark applies this metric consistently across various administrative tasks, including visit notes, diagnosis codes, and clinical decision support.
- ▪An initial measurement reported an aggregate Effort Reduction of 97.99% based on over one million signed encounters across thirteen medical specialties.
- ▪The paper provides a reporting protocol to ensure that Effort Reduction claims are auditable and comparable across different clinical AI systems.
