Copied to clipboard
| Challenge: | Clinical dialogue systems can enhance patient education and follow-up care by providing brief and subjective messages that lack critical clinical context. |
| Approach: | They propose a safety-aware dialogue system that applies information-gain guided clarification before RAG-based response generation and screens user utterances for emotional distress and suicidal ideation. |
| Outcome: | The proposed system improves quality and clinical appropriateness relative to strong baselines while aligning with expert judgments on clinically concerning utterances. |
