HTTP Interface and External Systems for Pharmacoeconomics

Data Characteristics in this Category

Pharmacoeconomics quality documentation typically includes clinical trial data, real-world evidence, cost-effectiveness analysis models, sensitivity analysis results, health technology assessment reports, and various policy and regulatory documents. Data sources are diverse, including public databases, journal literature, drug registration information, hospital financial data, and clinical pathways. Update frequencies vary; clinical guidelines and policies may update annually or quarterly, while drug prices and medical insurance payment standards can change monthly. Document structures are complex, often containing numerous charts, appendices, and cross-references. Fields involve drug generic names, indications, treatment plans, efficacy indicators (e.g., QALY, DALY), cost components (direct costs, indirect costs), effect units, and discount rates. Units are diverse, such as USD, CNY, life-years, and quality-adjusted life-years, requiring consistent conversion across different data sources.

Constraints Imposed by These Characteristics on "HTTP Interface and External Systems"

The diversity and complexity of pharmacoeconomics data require HTTP interfaces with robust data parsing and processing capabilities. Heterogeneous data from multiple sources mean that calling external system interfaces necessitates specific request parameters and response parsing logic for each data source. For example, obtaining clinical data from a public database differs significantly in API format and authentication from fetching policy documents from a government website. The frequent data updates, especially for drug prices and medical insurance payment standards, demand external system interfaces with high concurrency and low latency to ensure real-time data validity. The presence of charts and complex structures in documents means traditional text parsing is insufficient for complete information extraction, potentially requiring integration with image recognition or structured document parsing services. Furthermore, standardization of fields and units is critical; HTTP interfaces must define clear conversion rules during data transmission to prevent errors due to inconsistent units. The extensive content of these documents also challenges interface request body sizes and response times.

Configuration Settings

Configuration Item	Suggested Value	Rationale for this Value
`requestTimeout`	`600 seconds`	Pharmacoeconomics reports often contain extensive charts and complex text, requiring longer parsing times. This prevents request timeouts.
`maxChunkSize`	`800–1200 characters`	Ensures individual segments contain sufficient contextual information while avoiding excessively large segments that affect retrieval efficiency.
`fileSizeLimit`	`100 MB`	Accommodates quality documents containing multimedia or high-resolution charts, allowing large file uploads.
`concurrentRequests`	`Calibrate by actual measurement`	Balances system performance and stability when acquiring data from multiple sources, preventing external system overload.
`responseSchemaValidation`	`Strict validation`	Ensures data structures obtained from external interfaces conform to expectations, preventing parsing failures due to format changes.
`retryAttempts`	`3 times`	Addresses transient external service failures or network fluctuations, improving data acquisition success rates.

Three Common Mistakes

An HTTP request returns a timeout error after 60 seconds. The default interface timeout is too short to cover the complete processing cycle of large pharmacoeconomics documents.
Cost data fields obtained from an external system are empty. The external interface's JSON structure does not match expectations, or critical unit conversion logic is missing.
When multiple files are passed as parameters to an AI Agent, only the first file is processed. The interface parameter design did not adequately consider multi-file upload scenarios, leading to subsequent files not being correctly identified or processed.

How to Verify Correct Configuration

Perform multiple upload and processing operations for pharmacoeconomics documents of varying sizes and complexities. Check if the interface returns status codes 200 or 201.
Randomly select processed documents and verify key cost and efficacy indicator fields, confirming that their values and units match the original documents.
Simulate high-concurrency scenarios. Observe interface response times and error rates to ensure system stability under load, and adjust the concurrentRequests parameter based on actual load conditions.
