Data characteristics
Clinical Decision Support (CDS) system data originates from internal medical institution regulations, Standard Operating Procedures (SOPs), clinical guidelines, drug inserts, and clinical pathway documents. These documents commonly exist as PDFs, Word files, or structured databases.
Update frequency varies. Large medical institutions update regulations and SOPs every six to twelve months. Drug and clinical guideline sections update based on national policies or clinical research, with cycles ranging from weeks to months.
CDS system documents typically have clear chapter and heading hierarchies. Content includes specialized terminology, dosage units, diagnostic criteria, and treatment protocols. Fields and units include milligrams (mg) and milliliters (ml) for drug dosages, hours (h) and days (d) for time, and various units like mmol/L and g/L for lab indicators. Unit representations may differ slightly across documents.
Constraints from "Citation and Traceability"
The highly specialized and rigorous nature of CDS system data demands accurate and traceable citations. Varying document update frequencies require version management in the knowledge base to ensure citations use the latest effective version.
Structured document content requires retrieval to locate relevant text blocks and identify their chapter, paragraph, or specific table/figure. This meets clinical practice demands for precise information. Specialized terminology and diverse units require vectorization models to understand medical vocabulary, preventing retrieval errors due to lexical differences.
For citation traceability, the system must clearly present the original document's name, version number, and the text block's page number or location within the document. This is critical for clinicians to verify information and adhere to guidelines, directly impacting medical safety and compliance.

Configuration settings
| Configuration Item | Suggested Value | Rationale |
|---|---|---|
Chunk size (Chunk Length) | 300–500 characters | Maintains context in procedural SOPs/guidelines. |
Recall count (Recall Count) | Top 8–12 | Covers multiple regulations/guidelines, increasing relevant information recall. |
Similarity threshold (Similarity Threshold) | 0.85–0.92 | Reduces false positives, ensuring high relevance to clinical questions. |
Rerank result count (Reranked Return Count) | Top 3–5 | Focuses on the most relevant regulations/SOPs, reducing physician reading burden. |
metadata_fields | File Name, Version, Page Number | Ensures complete traceability for quick location of original source. |
chunk_separator | \n\n | Distinguishes paragraphs, reducing cross-paragraph semantic confusion. |
Common pitfalls
- Missing or inaccurate citations in answers (e.g., only file name without page number). This occurs when page number information is not correctly extracted or stored during document parsing.
- Retrieval results include outdated or superseded policy content. This occurs when the knowledge base is not updated promptly or version management fails.
- Quoted text blocks lack context, leading to semantic ambiguity when dealing with complex tables
