Deployment and Upgrade for Patient Assistance Program

Data Characteristics for This Category

Patient Assistance Program (PAP) application data typically includes basic patient information, diagnostic proofs, medication records, financial status documents, and program application/approval documents. This data originates from medical institutions, paper or electronic materials submitted by patients or their families, and pharmaceutical companies' internal project management systems. Data update frequency varies: patient information and medication records may update in real-time with treatment progress, while financial status proofs are usually submitted during the initial application with fewer subsequent changes. Document structures are diverse, including structured database records, semi-structured electronic medical records, and unstructured scanned images or PDF files. Fields and units are specific to the biomedical domain, such as diagnostic codes (ICD-10), generic drug names, dosage units (mg/kg), administration frequency, and various medical laboratory indicators.

Constraints Imposed by These Characteristics on "Deployment and Upgrade"

The diversity and complexity of PAP data introduce specific requirements for FastGPT deployment and upgrades. Pre-processing capabilities for unstructured documents become critical, requiring more resources for OCR and document parsing modules. The non-real-time nature of data updates dictates the focus of knowledge base synchronization strategies; batch import and periodic incremental updates are primary approaches. The specificity of medical terminology and measurement units demands stronger semantic understanding from the model during embedding and retrieval phases to avoid information discrepancies due to inaccurate recognition of specialized vocabulary. Furthermore, the sensitive nature of data sources (patient privacy) makes localized deployment and strict data isolation preferred, imposing higher demands on the security and stability of containerized deployments. During version upgrades, particular attention is necessary for model compatibility and data migration plans to ensure seamless integration of historical knowledge bases.

Configuration Settings

Configuration Item	Recommended Value	Rationale
`UPLOAD_FILE_MAX_SIZE`	`500 MB`	Patient diagnostic proofs and imaging reports can be large; ensure successful uploads.
`PARSE_FILE_TIMEOUT_SECONDS`	`600 seconds`	OCR parsing of large PDF documents or scanned images takes time; allow sufficient processing time.
`Chunk size` (Segment Length)	`800–1200 characters`	Ensure completeness of medical terminology and context to improve retrieval accuracy.
`Recall count` (Retrieval Count)	`Top 8 entries` (Top 8)	Increase retrieval scope to cover more potentially relevant patient assistance terms or approval criteria.
`Similarity threshold` (Similarity Threshold)	`0.78`	Balance retrieval precision and generalization, avoiding omission of critical information.
`QWEN_EMBEDDING_MODEL`	`qwen3-embedding-8b`	Optimized for specialized vocabulary in the biomedical domain, improving embedding quality.

Three Common Mistakes

When configuring the Redis image in docker-compose.yml, pulling from domestic mirror sources like Alibaba Cloud may fail. This usually happens due to mismatched image names or tags, or incorrect private repository authentication information.
The FastGPT administrator (root) account password automatically resets to its default value after deployment. This is not a system mechanism; it typically occurs because deployment scripts or operational automation tools re-execute initialization operations within a specific cycle, overwriting user-defined passwords.
After configuring the Qwen3-embedding model, knowledge base index rebuilding takes too long or fails. This can be due to insufficient server memory or CPU resources to support the computational demands of large embedding models, or incomplete model file downloads.

How to Verify Configuration

Upload a PDF file containing patient diagnostic information and medication records. Observe if the file is successfully parsed and knowledge base segments are generated.
In the FastGPT administration interface, check if the displayed values for parameters like UPLOAD_FILE_MAX_SIZE and PARSE_FILE_TIMEOUT_SECONDS match the configurations in docker-compose.yml or environment variables.
Perform tests using query statements that include medical professional vocabulary. Compare whether the retrieved results contain expected patient assistance terms or relevant approval process documents. Observe changes in the number of retrieved items by adjusting the Similarity threshold (Similarity Threshold).
