Researchers have developed MamaBench, a novel benchmark designed to assess the robustness of large language models (LLMs) in maternal and child health diagnostics. This benchmark utilizes counterfactual clinical narratives to evaluate how well LLMs can distinguish between similar conditions that require different interventions, revealing that standard accuracy metrics can overstate a model's true performance by 16-28 percentage points. The study also introduces Evidence-Anchored RAG (EA-RAG), a retrieval method that improves robust accuracy, achieving a 5.5 percentage point reduction in Bias Trap Rate on Claude Sonnet 4.6, though significant challenges in counterfactual robustness for clinical AI remain.
