Data Characteristics
R&D documents in nursing management primarily originate from clinical practice reports, nursing care plan designs, outcome evaluation records, and standard operating procedures (SOPs). These documents update frequently, especially with new nursing technologies or optimized existing plans. Document structures often include extensive free-text descriptions, charts, and structured nursing records. These records cover patient basic information, nursing diagnoses, interventions, and evaluation indicators. Specific fields include nursing-specific assessment scales like "Braden Score" and "Barthel Index." Units involve time (minutes, hours), dosage (milligrams, units), and frequency (times/day). Documents also contain numerous abbreviations and specialized terminology.
Constraints on Database and Operations
Frequent updates of nursing management documents require efficient incremental indexing in the database. This avoids performance bottlenecks from full re-indexing. The mix of free-text and structured data necessitates combining vector storage with traditional relational databases. Unique assessment scales and specialized terminology demand higher domain adaptability for text segmentation and embedding models. This may require custom dictionaries or fine-tuned models. Patient sensitive information in documents makes data anonymization and access control critical for operations, ensuring data security and compliance. Numerous abbreviations and informal expressions increase parsing complexity, requiring more refined preprocessing steps and potentially affecting retrieval accuracy.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 50 MB | Nursing plan documents may contain many images and charts; ensure sufficient upload capacity. |
Chunk size (Segment Length) | 500–800 characters (characters) | Balances contextual completeness of nursing records with retrieval efficiency; avoids segments that are too long or too short. |
Recall count (Recall Count) | Top 8 entries (top 8 items) | Ensures coverage of multiple information points in nursing plans; performs initial relevance filtering. |
Similarity threshold (Similarity Threshold) | 0.75 | Nursing management terminology is specialized and context-sensitive; increasing the threshold reduces false positives. |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds (seconds) | Complex PDF or Word document parsing can be time-consuming; allocate sufficient processing time. |
Rerank result count (Rerank Return Count) | Top 3 entries (top 3 items) | After initial recall and reranking, focus on the most core and highly relevant nursing guidance content. |
Common Mistakes
- Slow message responses, frequently exceeding 30 seconds. This typically occurs when complex retrieval optimizations (like query optimization and result reranking) are enabled, but backend computing resources are insufficient to handle multi-stage text processing and model calls promptly.
- Unable to create a database after local deployment, with connection errors or insufficient permissions. This often indicates an incorrect
DATABASE_URLconfiguration or that the database service (e.g., PostgreSQL) is not properly started or its listening port is blocked by a firewall. - Tool selection concurrency issues, failing to execute as expected with a one-of-two choice. This might be due to insufficiently strict conditional logic in the workflow design, or overlapping trigger conditions for tools, causing multiple tools to be matched and executed simultaneously.
Verification Steps
- Upload and parse a typical nursing plan document containing charts. Check if knowledge base segmentation is reasonable and if key information is correctly extracted.
- Perform a retrieval query using questions that include nursing professional terminology and scales. Verify the relevance and accuracy of returned results. Evaluate if similarity scores meet expectations.
- Simulate a high-concurrency scenario, such as sending more than 10 queries simultaneously. Observe if system response times are within an acceptable range. Check backend logs for abnormal errors or resource bottleneck warnings.
- For fields containing sensitive information in documents, verify that anonymization rules are effective. Test if data access ranges for different permission levels are correctly restricted.
