Data Characteristics in this Category
Clinical trial pre-screening data in health management primarily comes from personal health records, physical examination reports, wearable device data, and survey questionnaires. Data update frequencies vary; physical examination reports typically update annually, while wearable device data can be real-time or daily. Document structures are diverse, including unstructured doctor's notes, semi-structured lab results, and structured health metric tables. Fields often contain numerous medical terms, abbreviations, and units, such as blood pressure (mmHg), blood glucose (mmol/L or mg/dL), complete blood count (various cell counts), and drug dosages (mg, g, ml). The data frequently includes sensitive personal health information, requiring strict privacy protection.
Constraints Imposed by These Characteristics on Multiturn Conversation and Prompt Design
The diversity and update frequency of health management data directly impact the accuracy and timeliness of information retrieval in multiturn conversations. Unstructured doctor's notes require more sophisticated natural language processing to extract key information. This increases the complexity of prompt design to ensure the model correctly understands and correlates context. The presence of medical terms and units requires prompts to guide the model in unit conversion or medical concept explanation, preventing pre-screening errors due to misunderstandings of specialized terminology. Highly sensitive data necessitates built-in privacy protection mechanisms at the prompt level. For example, prompts should avoid directly asking for or storing sensitive information, instead guiding users to provide de-identified or generalized descriptions. The asynchronous nature of data updates means the conversation system must clearly distinguish between historical and current data, and prompt users to supplement or confirm the latest status in multiturn conversations.
Configuration Settings
| Configuration Item | Suggested Value | Rationale |
|---|---|---|
maxContext | 10 | Health management multiturn conversations often involve multiple health metrics and historical records, requiring a longer conversation context for comprehensive judgment. |
temperature | 0.3 | Clinical pre-screening demands rigorous and accurate judgment. A lower temperature value helps the model produce more certain and consistent results. |
Recall count | 15 | Considering the breadth and depth of user health records, increasing the number of recalled items can cover more relevant health data and medical history. |
Similarity threshold | 0.75 | Ensures that recalled health data is highly semantically relevant to user queries or model inferences, reducing interference from irrelevant information. |
Rerank result count | 5 | Based on a high recall volume, re-ranking focuses on the most relevant few pieces of information, improving model processing efficiency and accuracy. |
Chunk size | 800–1200 characters | Health management documents, especially doctor's notes, often contain lengthy narratives, requiring longer segment lengths to maintain semantic integrity. |
Common Pitfalls
- Phenomenon: AI responses show confusion in medical units or numerical errors, such as blood pressure units changing from mmHg to kPa. Reason: Prompts failed to clearly specify units or require the model to perform unit conversions, leading to model confusion when processing multi-source data.
- Phenomenon: Users report loss of conversation history or inability to retrieve specific session content. Reason: The conversation management system did not correctly configure persistent storage for
sessionID, or did not isolate session data in multi-user scenarios. - Phenomenon: The model excessively asks for sensitive personal information during pre-screening, or fails to recognize de-identified information provided by the user. Reason: Prompts did not effectively guide the model to identify and process sensitive information, nor did they provide sufficient examples to train the model to understand user privacy protection intent.
How to Confirm Correct Configuration
- Simulate multiturn conversations with users of different health conditions. Check if medical unit consistency is maintained in AI responses and compare them with original data sources.
- In multi-user concurrent scenarios, log in with different user accounts. Verify that each user's conversation history is independent and complete. Attempt to query the historical
messageIdfor any session. - Design pre-screening scenarios that include sensitive information. Observe if the model avoids direct questioning, instead guiding users to provide generalized descriptions or confirm de-identified information. Check logs for sensitive data that should not appear.
