Deployment and Upgrade for CSO Pharmacovigilance

Data Characteristics

Data in the pharmacovigilance domain for Contract Sales Organizations (CSOs) primarily originates from sales data of partner pharmaceutical companies, patient feedback, physician reports, and public literature searches. This data exists as unstructured text (e.g., patient descriptions, report details), semi-structured forms (e.g., adverse event report forms), and structured database records (e.g., drug batch information, patient demographics). Data updates frequently; adverse event reports can occur in real-time, and sales data typically updates daily or weekly. Document structures vary, including PDF medical reports, Word document user manuals, and various database export files. Fields and units are industry-specific, such as drug generic names, batch numbers, dosage units (mg, g, ml), administration routes, and adverse reaction codes (e.g., MedDRA codes).

Constraints on Deployment and Upgrade

The high update frequency and diverse document structures of CSO pharmacovigilance data require the deployed AI platform to have efficient data ingestion capabilities and flexible parsing adapters. Real-time processing of unstructured text necessitates robust Natural Language Processing (NLP) capabilities to accurately identify and extract key information. Multi-source heterogeneous data means that during upgrades, compatibility across different data interfaces must be ensured, and data models must iterate to adapt to new data types or fields. The extensive medical terminology and specialized coding demand that models accurately understand context during inference to avoid errors caused by lexical ambiguity. Furthermore, handling highly sensitive medical data imposes strict requirements on system stability and security. Any upgrade requires thorough regression testing to ensure data privacy and processing accuracy.

Configuration Settings

Configuration Item	Recommended Value	Rationale
`maxContext`	`32768 tokens`	Ensures the large language model can process longer patient descriptions and medical reports, maintaining contextual integrity.
`PARSE_FILE_TIMEOUT_SECONDS`	`600 seconds`	Accommodates the parsing time for complex PDF and Word documents, preventing timeouts due to large files.
`Chunk size`	`800–1200 characters`	Balances textual semantic integrity and recall efficiency, ensuring critical information is not truncated.
`Recall count`	`Top 10 entries`	Improves the accuracy and comprehensiveness of retrieving relevant adverse event cases from the knowledge base.
`Similarity threshold`	`0.75`	Filters highly relevant adverse event reports or drug information, reducing false positives.
`Rerank result count`	`Top 5 entries`	Reranks recall results to ensure the most valuable information is presented.

Common Pitfalls

Large language model inference results are too short, failing to fully address adverse reaction analysis requirements. This often occurs because the maxContext configuration is insufficient, limiting the model's output length.
Uploading large medical report files results in a request failure or parsing timeout. This is typically due to PARSE_FILE_TIMEOUT_SECONDS being set too low, unable to handle the parsing time for complex documents.
After a version update, the data type of certain fields is fixed during mcp service calls, causing data transmission errors. This usually happens when the new version has adjusted data model or API parameter definitions, requiring a check of type parameter compatibility.

Verification

Upload typical pharmacovigilance reports in various formats (PDF, DOCX, TXT) and sizes. Observe if file parsing is successful and if the parsed text content is complete and accurate.
For several known adverse event cases, input relevant queries. Verify if the large language model's inference results accurately identify drugs, symptoms, and adverse reactions, and meet the expected level of detail.
Simulate high-concurrency requests by continuously submitting adverse event reports. Monitor system logs related to PARSE_FILE_TIMEOUT_SECONDS and maxContext to confirm no timeouts or context truncation errors.
Check mcp service call logs to confirm that the type parameter is passed as expected and is not forcibly converted to an incompatible data type.
