Model Integration and Configuration for Infection Control

Data Characteristics for this Product Category

Infection control product data originates from various sources within medical institutions. These include infection surveillance systems, medical record systems, laboratory reports, drug usage records, environmental monitoring data, and national or local infection control guidelines. Data updates frequently, especially during outbreaks or the emergence of new pathogens, when guidelines and surveillance data are updated in real-time.

Document structures are diverse:

Unstructured: Clinical orders, nursing notes, infection incident reports.
Semi-structured: Laboratory results (e.g., microbial culture reports).
Structured: Patient demographic information, diagnosis codes, drug codes.

Fields and units are highly specialized. Examples include microbial names, antimicrobial susceptibility profiles, antibiotic dosages (mg/kg), infection site codes (ICD-10), and infection rates (‰).

Constraints Imposed by Data Characteristics on Model Integration and Configuration

The diversity and specialized nature of infection control data impose strict requirements on model integration.

Unstructured text (e.g., medical orders and reports) requires robust text parsing capabilities to accurately extract key information like infectious pathogens, treatment regimens, and infection sites.
Semi-structured and structured data require the model to recognize and process specific medical terminology and coding systems.
High-frequency data updates necessitate an efficient incremental update mechanism for the knowledge base. This ensures the model consistently provides consultations based on the latest guidelines and surveillance data.
Specialized domain vocabulary and units challenge the model's understanding and generation capabilities. The model must accurately identify and output medically compliant expressions, avoiding critical information errors due to misunderstanding or confusion (e.g., confusion between antibiotic names or dosage units).

Configuration Guidelines

Configuration Item	Recommended Value	Rationale
`modelName`	`deepseek-v2` or `qwen-max`	Strong Chinese comprehension and generation capabilities, handles specialized medical terminology.
`Chunk size` (Segment Length)	`500–800 characters` (characters)	Balances contextual completeness with information density per segment, reducing comprehension difficulty.
`Recall count` (Recall Count)	`8–12 entries` (items)	Ensures coverage of sufficient relevant knowledge points, improving answer accuracy.
`Similarity threshold` (Similarity Threshold)	`0.75`	Filters out irrelevant documents, reduces noise interference, and focuses on core issues.
`Rerank result count` (Rerank Return Count)	`3–5 entries` (items)	Further refines the most relevant knowledge snippets, enhancing answer quality.
`maxContext`	`16384`	Accommodates lengthy medical reports and multi-turn conversations, preventing context truncation.

Common Configuration Pitfalls

Model output includes unnecessary spaces or case confusion. For example, PenicillinG becomes Penicillin Penicillin Penicillin G, or Penicillin G becomes penicillin G. This often results from insufficient character normalization when the model processes complex text or switches languages.
After local deployment of an Ollama model, tests consistently return 500 errors or connection timeouts. This usually indicates a mismatch between the FastGPT configured baseUrl or apiKey and Ollama's actual listening address or port, or firewall rules blocking the connection.
The model inappropriately modifies or summarizes content from links provided in the knowledge base, leading to invalid links or distorted information. This typically occurs when prompt constraints on link handling are not clear enough, or the model's adherence to instructions is insufficient.

Configuration Verification

Upload several typical infection surveillance reports or control guidelines to the knowledge base. Ask questions about key information within them. Check if the model accurately recalls relevant passages and provides correct answers.
Simulate real consultation scenarios. Ask about treatment plans or prevention measures for specific pathogen infections. Verify that the model's output professional terminology, drug names, and dosage units comply with medical standards.
Monitor whether the model strictly adheres to prompt requirements when handling knowledge containing external links, ensuring no changes are made to link content. Verify that the output links are accessible.
