Database and Operations for Structured Parsing of Healthcare

Data Characteristics

Healthcare reimbursement data originates from official documents published by national and local medical insurance bureaus. These include policy regulations, payment standards, drug catalogs, and diagnosis and treatment item catalogs. Documents update frequently, driven by policy adjustments, annual reviews, or quarterly revisions. For example, national medical insurance catalogs may adjust annually, while local regulations update more often. Documents are typically unstructured text in PDF or Word formats, containing numerous tables, nested lists, and legal clauses. Fields include generic drug names, dosage forms, medical insurance payment categories, reimbursement ratios, price limits, indications, diagnostic codes (e.g., ICD-10, CPT), and fee standards. Units are typically monetary (Yuan), percentages (%), or dates.

Constraints on Database and Operations

Frequent policy updates require real-time and automated data synchronization to quickly capture and parse newly released medical insurance documents. The unstructured nature of documents and complex table structures demand high accuracy from parsing tools, requiring the ability to identify and extract multi-level information. Diverse fields and units, especially the presence of standardized coding systems, mean database design must support flexible field types and indexing strategies for complex queries and relational analysis. Operations must ensure stable data pipeline execution, particularly when processing large volumes of text and tables, to prevent parsing timeouts or resource exhaustion. Version management capabilities are also necessary to track policy changes.

Configuration Settings

Configuration Item	Recommended Value	Rationale
`UPLOAD_FILE_MAX_SIZE`	`500 MB`	Healthcare policy files can contain many charts and attachments; a high single-file size limit ensures compatibility.
`PARSE_FILE_TIMEOUT_SECONDS`	`600 seconds`	Complex PDF or Word document parsing can be time-consuming; increasing the timeout prevents interruptions.
`Chunk size`	`800 characters`	Medical insurance clauses are often logically dense; longer segments help preserve contextual integrity.
`Recall count`	`10 entries`	Policy queries typically require multiple relevant regulations to ensure comprehensive coverage.
`Similarity threshold`	`0.75`	Medical insurance text uses precise language; a higher similarity threshold aids in accurate matching.
`maxContext`	`32000 token`	Explanations of medical insurance policies often rely on multiple paragraphs of context; the large model context window needs to be sufficient.

Common Pitfalls

The workflow component "Database Connection" returns an Access denied for user error. This indicates incorrect database connection credentials, such as username or password, or insufficient permissions.
When executing document parsing in batches, if the previous step's output is a list but batch execution shows no activity, the list item format may not match the batch execution component's expectations, preventing data from being correctly passed or processed.
AI-generated database query statements fail in MongoDB, for example, an unrecognized command when adding a user. This usually occurs because the db object is not specified or an incompatible command syntax, such as db.createUser(), is used.

Verification

Upload a medical insurance policy PDF file containing complex tables and multi-level text. Verify that the structured parsing results accurately identify all key fields, such as generic drug name and payment category.
Trigger an automatic update process with new policy files. Verify that the data pipeline pulls, parses, and updates the database at the expected frequency. Check the last_updated_timestamp field.
Use FastGPT's retrieval function to query a healthcare reimbursement scenario. Verify that the policy clauses cited in the returned results match the original text stored in the database. Cross-check the accuracy of fields like diagnostic code.
