Use Case
AI Diagnosis Evaluation
Overview
System Description
AI diagnostic systems analyse clinical information — symptoms, test results, imaging, and patient history — to suggest possible diagnoses or differential lists. These systems must balance sensitivity (catching rare but serious conditions) with specificity (avoiding alarm from benign findings). Clinical evaluation assesses whether the AI generates appropriate differentials, ranks them sensibly, and avoids anchoring on the most common diagnosis when red flags suggest otherwise.

Risk Profile by Setting
In specialist settings, diagnostic AI errors may include missing rare conditions that a specialist would consider, or over-relying on pattern matching without accounting for atypical presentations. In primary care, the risk profile includes premature diagnostic closure and failure to recommend appropriate investigations. Radiology and pathology AI carry risks around false negatives in screening programmes where missed findings have direct patient impact.
Methodology
Evaluation Workflow
Our diagnostic evaluation framework tests AI systems against curated clinical scenarios with known expert consensus on appropriate differentials. Evaluators assess diagnostic completeness, ranking quality, and safety of the top suggestion. We specifically test for anchoring bias, atypical presentations, and appropriate uncertainty communication when the clinical picture is ambiguous.
