Multi-turn Conversation and Prompts for Clinical Decision

Data Characteristics in This Category

Clinical Decision Support System (CDSS) registration documents primarily include product technical documentation, clinical trial reports, risk management reports, and user manuals. Data sources are diverse, encompassing medical literature, guidelines, drug inserts, disease databases, genomic data, and Electronic Medical Record (EMR) data. Update frequencies vary; medical guidelines and drug inserts may update annually, while clinical trial data is submitted in batches. Document structures are complex, often containing extensive unstructured text, tables, charts, and structured data adhering to specific regulations (e.g., ICH E6 GCP, FDA 21 CFR Part 11). Fields and units are highly specialized, such as dosage units (mg/kg), time units (days, weeks, months), and biomarker units (ng/mL), with extremely high demands for data accuracy and consistency.

Constraints Imposed by These Characteristics on "Multi-turn Conversation and Prompts"

The complexity of clinical decision support data places high demands on the accuracy of multi-turn conversations and the refinement of prompts. First, multi-source heterogeneous data requires robust information integration capabilities. Prompt design must guide the model to retrieve key information from various document types. Second, frequently updated data, especially medical guidelines and drug/device inserts, means the knowledge base needs regular synchronization to ensure the timeliness of conversation results. Third, the abundance of specialized terminology, abbreviations, and specific formats in documents requires prompts to effectively parse and guide the model to understand their contextual meaning, preventing misjudgments due to semantic ambiguity. Finally, strict requirements for data accuracy and compliance mean the conversation system must trace information sources and, when necessary, cite original text, which challenges the guidance capabilities of prompts.

Configuration Settings

Configuration Item	Recommended Value	Rationale
`maxContext`	`8192 token`	Context length required for long technical documents and clinical reports
`Chunk size`	`800–1200 characters`	Balances semantic completeness and recall efficiency, adapts to technical document paragraph length
`Recall count`	`Top 8–12 entries`	Covers multiple aspects of information, ensures comprehensive retrieval
`Similarity threshold`	`0.78–0.85`	Filters irrelevant content while retaining subtle differences in specialized terminology
`PARSE_FILE_TIMEOUT_SECONDS`	`600 seconds`	Parsing time for large clinical trial reports and technical specification documents
`Rerank result count`	`Top 5 entries`	Focuses on the most relevant key information, optimizes model input

Three Common Mistakes

Document upload in conversation shows a 503 error: This usually occurs because the file size exceeds UPLOAD_FILE_MAX_SIZE or file parsing times out PARSE_FILE_TIMEOUT_SECONDS, causing the gateway or backend service to reject the request.
After integrating the knowledge base, the AI responds "No answer found," but relevant content exists in the knowledge base: This may be due to Similarity threshold (similarity threshold) being set too high, or Chunk size (segment length) being inappropriate, leading to effective information being split or not recalled.
Inability to correctly understand specialized terminology or abbreviations in conversation: The prompt lacks clear instructions for domain-specific vocabulary, or the knowledge base does not sufficiently include and explain these professional terms, preventing the model from accurately identifying and utilizing them.

How to Confirm Proper Configuration

Select typical registration documents and perform multi-turn questioning. Check the accuracy of specialized terminology and contextual consistency in responses.
Upload documents of varying sizes and complexities. Observe if the file upload and parsing process is smooth, and check backend logs for any abnormal status codes.
For specific clinical decision scenarios, pose complex questions requiring the integration of multi-source information. Evaluate whether the model can accurately cite data and conclusions from different types of documents.
