HTTP Interface and External Systems for Telemedicine Quality

Data Characteristics

Telemedicine quality documentation includes electronic medical records, diagnostic reports, treatment plans, remote consultation records, patient feedback, and medical equipment operating procedures. This data often resides across various medical information systems (e.g., HIS, EMR, PACS). Data update frequency is relatively high, especially for patient treatment records, which can be generated in real-time. Document structures contain both structured data fields (e.g., ICD-10 diagnostic codes, drug codes) and extensive unstructured text (e.g., physician's handwritten progress notes, consultation opinions). Field units involve medical measurements like mg, ml, mmHg, and timestamp formats such as YYYY-MM-DD HH:MM:SS.

Constraints Imposed by HTTP Interface and External Systems

The diverse data sources for telemedicine quality documentation require the HTTP interface to have flexible data source integration capabilities, allowing connection to APIs provided by different medical systems. Real-time requirements imply potentially high interface call frequency, necessitating consideration of concurrent processing and response speed. The presence of unstructured text increases data preprocessing complexity, possibly requiring additional text cleaning and structured extraction after interface calls. The specialized nature of medical fields and units demands that the interface correctly identifies and processes this information during data transmission and parsing, preventing data errors due to unit conversion or field misinterpretation. Furthermore, patient privacy protection and data security are core considerations; interface design must comply with regulations like HIPAA or GDPR, ensuring encrypted data transmission and access control.

Configuration Guidelines

Configuration Item	Recommended Approach	Rationale
`apiBaseUrl`	Actual API gateway address of the medical system	Ensures requests are sent to the correct backend service
`requestTimeout`	`60 seconds`	Telemedicine data volumes can be large; prevents timeouts due to network latency or excessive processing time
`maxRetries`	`3`	Addresses temporary network fluctuations or brief backend service unavailability, improving interface call success rate
`headers`	`Authorization: Bearer <token>`	Medical systems typically use OAuth2 or JWT for authentication, ensuring data security
`responseSchema`	JSON Schema definition	Ensures received data structure conforms to expectations, facilitating subsequent parsing and processing
`dataPollingInterval`	`300 seconds` or calibrated based on actual measurements	Balances data real-time requirements with system load, according to telemedicine data update frequency and business needs

Common Pitfalls

API calls return 401 Unauthorized or 403 Forbidden: This typically occurs because the token in the Authorization header is expired, invalid, or the requesting account lacks sufficient permissions to access the target resource.
Interface calls succeed, but returned data fields are empty or incorrectly formatted: This might be due to an incorrectly defined responseSchema, preventing the parser from matching the returned JSON structure, or the backend service returning data that does not conform to the agreement.
Requests are frequently rejected or result in 429 Too Many Requests: Medical system APIs may have call frequency limits. This can happen if appropriate request intervals or rate limiting are not implemented.

Verification Steps

Manually call the interface using Postman or curl, including the configured apiBaseUrl, headers, and payload, to confirm successful retrieval of data in the expected format.
After completing configuration within FastGPT, perform a data synchronization or call test. Check log output to confirm no HTTP 5xx error codes or connection timeout messages appear.
Examine the imported document content in the knowledge base. Verify that key fields obtained from the external system (e.g., patient ID, diagnosis results, treatment dates) are correctly parsed and stored, with accurate units.
Simulate high concurrency scenarios. Observe the interface call success rate and response time to ensure stable system operation under expected load, with response times within acceptable thresholds.
