Tool Calling and Plugins for Infection Control Clinical

Data Characteristics

Infection control clinical trial pre-screening data originates primarily from Hospital Information Systems (HIS), Laboratory Information Systems (LIS), and Electronic Medical Record (EMR) systems. This data combines structured and semi-structured formats. Structured data includes patient demographics, diagnosis results (ICD-10 codes), microbial culture results, and medication records (ATC codes). This data updates frequently, often in real-time or near real-time. Semi-structured data includes physician progress notes, nursing records, and infection control reports. This text-based information updates less frequently, perhaps daily or weekly. Microbial culture results typically include strain names, antimicrobial susceptibility testing (AST) results (MIC values or sensitive/intermediate/resistant classifications), and sampling sites. Medication records involve drug names, dosages, administration routes, and start/end times. MIC values are commonly in μg/mL. Drug dosages use various units, such as mg, g, and U.

Constraints Imposed by These Characteristics on Tool Calling and Plugins

The real-time nature of infection control data demands high concurrency and low latency for tool calls. This is especially critical when microbial culture results update, requiring immediate pre-screening initiation. Semi-structured text data requires complex Natural Language Processing (NLP) for key information extraction, potentially increasing computational load and response time for tool calls. Standardized microbial strains and drug codes (e.g., ICD-10, ATC) necessitate external database comparison and querying. This requires tools to integrate with external medical knowledge graphs or drug databases. Numerical data, such as AST MIC values or sensitive/resistant classifications, and drug dosages, require precise numerical comparison and unit conversion for decision logic. This demands high accuracy in tool parameter parsing and logical processing.

Configuration Guidelines

Configuration Item	Recommended Value	Rationale
`maxContext`	`4096`	Accommodates long text contexts like progress notes while balancing model processing capabilities.
`PARSE_FILE_TIMEOUT_SECONDS`	`600 seconds`	Allows sufficient time for parsing large EMRs or infection reports, preventing timeouts.
`Similarity threshold`	`0.75`	Ensures accurate matching of microbiological features with patient symptom descriptions, reducing false positives.
`Recall count`	`Top 10 entries`	Guarantees comprehensive clinical pathways and medication plans, covering potential associated information.
`Rerank result count`	`Top 5 entries`	Prioritizes the most relevant infection risk factors or treatment recommendations, improving efficiency.
`API_RATE_LIMIT_PER_MINUTE`	`Calibrate by actual measurement`	Determine based on the actual concurrency capacity and response latency of HIS/LIS system interfaces.

Common Pitfalls

Tool calls return HTTP 504 Gateway Timeout errors. This can occur when processing large volumes of medical record text or complex medical knowledge graph queries, and a single request's execution time exceeds the gateway's timeout limit.
Antimicrobial susceptibility results for specific microbes or drug dosage information are missing from clinical trial pre-screening results. This can happen if the document parser fails to correctly identify or extract non-standard numerical fields, leading to null parameters from the data source.
Pre-screening result accuracy fluctuates significantly, failing to correctly identify some patients as high-risk. This may be due to discrepancies between disease association rules or microbial characteristics in the knowledge base and actual clinical data. This requires updating the knowledge base or adjusting the Similarity threshold.

Validation Steps

Simulate pre-screening processes with real medical record data. Check if the response time for each step in the tool calling chain meets expectations.
Select known infection cases. Verify if pre-screening results accurately identify relevant infection risk factors, microbial information, and recommended treatment plans.
Review tool call logs. Confirm that all critical parameters (e.g., patient_id, microbe_name, drug_dose) are correctly transmitted and parsed before and after the call, with no null values or format errors.
