Citation and Traceability for Health Management Clinical

Data Characteristics in this Category

Health management clinical trial pre-screening data primarily originates from personal health records, physical examination reports, wearable device data, and some medical records. This data typically exists in structured formats (e.g., laboratory test results, vital signs) and semi-structured formats (e.g., doctor consultation notes, health assessment questionnaires). Data update frequency varies by source. Physical examination reports usually update annually, wearable device data may update in real-time or daily, and personal health record updates depend on the frequency of medical visits or health management activities. Document structures are diverse. For example, physical examination reports may contain multiple levels of indicators, while wearable device data is primarily time-series based. Fields include blood glucose, blood pressure, heart rate, steps, and sleep duration. Units are typically international standard units (e.g., mmol/L, mmHg, beats/minute).

Constraints Imposed by these Characteristics on Citation and Traceability

The multi-source and heterogeneous nature of health management data requires citation and traceability mechanisms to effectively integrate different data formats. Real-time or high-frequency updates from wearable device data demand immediacy in data indexing and retrieval, ensuring the timeliness of cited content. Semantic understanding and key information extraction capabilities for semi-structured text, such as doctor consultation notes, directly impact traceability accuracy. Furthermore, sensitive personal health information makes data anonymization and access control crucial considerations in the traceability process, ensuring cited content is visible under compliance. Standardization of fields and units is vital for consistent citation across data sources, preventing misunderstandings due to inconsistent units.

Configuration Settings

Configuration Item	Recommended Value	Rationale
`Chunk size` (Segment Length)	`500–800 characters`	Balances semantic completeness and recall efficiency. Avoids overly long paragraphs diluting key information and overly short paragraphs losing context.
`Recall count` (Recall Count)	`Top 8`	Balances retrieval accuracy and response speed. Covers primary relevant information and reduces unnecessary computational overhead.
`Similarity threshold` (Similarity Threshold)	`0.75–0.85`	Addresses the professional nature and specialized vocabulary of health management data. Ensures strong relevance of recalled content and reduces noise.
`Rerank result count` (Reranked Return Count)	`Top 3`	Focuses on the most critical citation evidence. Improves answer precision and reduces user reading burden.
`PARSE_FILE_TIMEOUT_SECONDS`	`600 seconds`	Handles parsing of large physical examination reports or merged documents of multiple historical records. Ensures complete processing of complex documents.
`maxContext`	`3000 Tokens`	Accommodates complex consultations or multi-indicator correlation analyses that may arise in the health management domain. Provides sufficient context.

Three Common Pitfalls

Answers that do not cite relevant content, or where cited content does not match the answer, typically result from a knowledge base recall similarity threshold set too high or a segment length that is too short, preventing the model from acquiring effective information.
Missing or incomplete citation sources may occur because of file parsing timeouts (PARSE_FILE_TIMEOUT_SECONDS parameter being insufficient) or because critical fields in the document were not correctly identified and indexed.
For questions about specific health indicators, if the answer does not include relevant data but the citation does, this usually indicates that maxContext is set too low, preventing the model from fully utilizing all recalled contextual information when generating the answer.

How to Verify Configuration

Submit a series of queries containing specific health management indicators (e.g., "blood glucose control target," "blood pressure fluctuation range"). Check if the answer accurately cites corresponding values and recommendations from the knowledge base, and verify the original cited snippets.
Upload a health record containing various data types (e.g., structured physical examination data, unstructured doctor's advice). Then, ask questions and check if all relevant information is correctly cited, verifying the completeness of the citation sources.
Simulate queries via the API interface. Check if the source_nodes field in the response contains the expected number and quality of cited items. Evaluate their relevance threshold based on business requirements.
