Data Characteristics
Clinical Decision Support (CDS) system regulations and Standard Operating Procedure (SOP) data originate from internal medical institution rules, operating manuals, guidelines, clinical pathways, and relevant legal documents. Data update frequency is relatively stable, typically quarterly or annually. Emergency revisions may occur during public health crises or policy changes. Document structures vary, including PDF, Word, and Markdown formats. They often feature strict hierarchical structures and cross-references.
CDS regulatory data involves specific fields and units: drug dosage units (mg/kg, U/day), examination indicator ranges (mmol/L, ng/mL), time periods (hours, days, weeks), and department-specific terminology and abbreviations. Documents frequently contain flowcharts, decision trees, and tables. These non-textual elements pose challenges for parsing and understanding.
Constraints on Multiturn Conversation and Prompts
The stable update frequency of CDS regulatory data necessitates a mechanism for regular or on-demand incremental updates to the knowledge base. This ensures accuracy in multiturn conversations.
Hierarchical structures and cross-references in documents require RAG retrieval to understand contextual relationships and avoid misinterpretations. This impacts chunking strategies and reranking algorithm selection.
Specific fields and units, such as drug dosages and examination indicators, demand precise citation and unit conversion in generated responses. Failure to do so could lead to serious medical errors.
Non-textual information like flowcharts, decision trees, and tables means that simple text chunking and retrieval are insufficient for complex decision logic. Additional image recognition or structured information extraction capabilities are required. This influences prompt design, guiding the model to extract answers from structured information.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunkSize | 800 characters | Clinical regulation documents have moderate paragraph lengths, balancing contextual completeness and retrieval efficiency. |
overlap | 100 characters | Ensures context continuity, preventing critical information from being split. |
recallQuantity | 5 items | Covers different regulatory sections, increasing diverse information sources. |
rerankQuantity | 3 items | Selects the most relevant regulatory clauses for the user's query, reducing redundancy. |
similarityThreshold | 0.75 | Balances recall and precision, ensuring high relevance of retrieval results to medical regulations. |
maxContext | 4096 tokens | Accommodates multiturn conversation history and retrieved regulatory content, supporting complex decision processes. |
Common Mistakes
- Unit or numerical errors in responses, such as confused drug dosage units or inaccurate examination indicator ranges. This results from a lack of standardized processing for numerical values and units in regulatory texts.
- Misunderstanding regulatory processes in multiturn conversations, leading to decision recommendations that do not align with actual operating procedures. This stems from insufficient parsing of structured information like flowcharts and decision trees.
- The system fails to recall or provides incomplete recall when users ask about specific regulatory clauses. This can occur if the chunking strategy is too aggressive, fragmenting related clauses excessively.
Verification of Configuration
- Select 10 typical clinical decision regulation documents. Query key numerical values and units, such as drug dosages, examination indicators, and time periods, to verify response accuracy.
- Design multiturn conversation scenarios for complex clinical pathways or decision processes. Validate whether the system's guidance and recommendations at various stages comply with regulations, especially regarding its understanding of flowcharts and decision trees.
- Test with regulatory clauses containing cross-references. Confirm the system maintains information integrity when tracing reference relationships and correctly displays the source of references.
- Simulate real clinical scenarios. Test if the system can prompt users for more information when faced with ambiguous or incomplete queries, ultimately providing regulation-compliant advice.
