Data Characteristics in Infection Control Management
Infection control management data originates from internal institutional regulations, operational guidelines, inspection records, training materials, and the latest guidelines and standards published by national health commissions. These documents are typically in PDF, Word, or scanned image formats. Update frequency is influenced by policy adjustments and hospital management requirements, generally occurring quarterly or annually. Document structures often include chapters, articles, and appendices for regulations and operational guidelines, while inspection records are frequently tabular. Common fields include "infection site," "pathogen type," "disinfection measures," "executor," and "inspection date." Units involve "cases," "times," "mg/L," and "℃." Some fields may contain medical terminology abbreviations.
Constraints Imposed by These Characteristics on "Workflow Orchestration"
The complex hierarchical structure of infection control documents requires the document parsing module in the workflow to accurately identify and extract key information from different levels, preventing information confusion. The update frequency and diverse sources of documents demand robust document synchronization and version management within the workflow, ensuring the knowledge base always uses the latest and most authoritative materials. The presence of tabular inspection records necessitates that the workflow has structured data processing capabilities to extract specific indicators from tables for comparison. Medical terminology abbreviations and diverse units require the workflow to effectively handle synonyms, near-synonyms, and unit conversions during text processing and knowledge matching, improving recall accuracy. Additionally, different document types may require different parsing strategies and knowledge base classifications, increasing the need for workflow branch decisions.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Chunk size (Segment Length) | 500–800 characters | Balances document context completeness with search recall efficiency, avoiding noise from overly long segments. |
Recall count (Recall Count) | 8–12 items | Ensures coverage of relevant knowledge points while controlling the input length processed by the model, reducing inference costs. |
Similarity threshold (Similarity Threshold) | 0.75–0.85 | For the specialized nature of medical texts, this range appropriately increases the threshold to filter out irrelevant information and ensure recall accuracy. |
Rerank result count (Reranked Return Count) | 3–5 items | Further refines the most relevant segments from the initial recall, improving the quality of the final answer. |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Allows sufficient time for parsing large PDF documents, preventing parsing interruptions. |
maxContext | 2000–3000 Tokens | Accommodates the potential for infection control questions to involve extensive background information, ensuring the model receives adequate context. |
Common Pitfalls
- Repeated parsing of existing documents within the workflow, leading to resource waste or historical data confusion, due to a lack of version validation and deduplication during document upload or update.
- Direct text segmentation when encountering tabular data, resulting in loss of metric data within tables or incomplete semantics, due to a failure to differentiate processing methods for structured and unstructured data.
- After retrieval from multiple knowledge bases, failing to effectively aggregate or filter answers from different sources, leading to redundant or conflicting information in the direct output, due to a lack of answer fusion or ranking logic in the workflow.
Validation Steps
- Upload a test set containing various document types (regulations, checklists) and observe document parsing logs to confirm all documents are successfully parsed without errors.
- Pose questions in the chat interface related to specific infection control management issues, checking if the model's output accurately cites relevant clauses and data from the knowledge base and correctly handles medical abbreviations.
- Simulate an infection event handling process to verify if the workflow's knowledge recall and response logic align with expectations across different branches (e.g., "infection reporting," "disinfection treatment"), particularly for identifying key fields like
infection siteandpathogen type.
