Pharmacoeconomics Data Characteristics
Pharmacoeconomics data originates from clinical trial reports, real-world evidence (RWE) studies, healthcare resource utilization data, drug pricing databases, and reports published by Health Technology Assessment (HTA) agencies. Data update frequencies vary. Clinical trial data typically releases with study progress, RWE data may update quarterly or annually, and drug pricing and reimbursement policy data can change monthly. Document formats are diverse, including PDF research reports, Excel or CSV cost-effectiveness analysis models, and structured database entries. Specific metrics include Quality-Adjusted Life Years (QALY), Incremental Cost-Effectiveness Ratio (ICER), disease burden, drug accessibility, and patient adherence. Units include USD/EUR, years, percentages, and various clinical outcome indicators. Data volumes are often large, sources are dispersed, and formats are complex.
Constraints Imposed by These Characteristics on Tool Calling and Plugins
The wide range of sources and diverse formats of pharmacoeconomics data require tool calling and plugins to have robust multi-source data integration capabilities and support various file types for parsing. For example, extracting structured data from PDF reports or parsing complex Excel models. Inconsistent data update frequencies necessitate flexible caching strategies and regular data synchronization mechanisms to ensure information timeliness. The specificity of fields, especially core metrics like QALY and ICER, requires plugins to understand and accurately process these specialized terms for correct numerical calculations or information extraction. Additionally, data often involves sensitive commercial information or patient privacy, which demands high standards for tool calling security, access control, and data anonymization. When processing large datasets, concurrency and stability of API calls also require significant consideration.
Configuration Guidelines
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Processing large PDF reports or complex Excel models requires longer parsing times to prevent file import failures due to timeouts. |
maxContext | 8000 tokens | Pharmacoeconomics reports are dense, containing extensive details and specialized terminology. A longer context window helps the model understand the full semantic meaning of the report. |
Chunk size (Segment Length) | 500 characters | Ensures each text segment contains sufficient information for the model to understand its context, while preventing excessively long segments from impacting retrieval efficiency. |
Similarity threshold (Similarity Threshold) | 0.75 | The pharmacoeconomics domain demands high precision in terminology. A higher similarity threshold more accurately matches relevant concepts and data. |
Rerank result count (Reranked Return Count) | 10 items | Initial retrieval may include partially irrelevant results. Increasing the number of reranked items improves the accuracy and comprehensiveness of search results. |
tool_request_timeout | 60 seconds | Accounts for network latency and external service processing time when calling external APIs to obtain real-time drug prices or HTA reports. |
Common Pitfalls
HTTP 500errors when calling external APIs often occur because service interfaces, such as Volcengine, return data in an unexpected format or due to expired authentication tokens.- After importing large PDF documents or complex Excel files, some critical numerical values or table contents may not be correctly identified and extracted. This happens when the file parser has insufficient compatibility with specific layouts or non-standard formats.
- The model provides answers to pharmacoeconomics questions using outdated or inaccurate data. This typically results from external data source caches not being updated promptly or a lack of effective data version control mechanisms.
Verification Steps
- Upload and parse a pharmacoeconomics PDF report containing tables and charts. Verify that key data fields (e.g., ICER values, QALY) are correctly extracted.
- Call an external drug price query API via a tool to verify the real-time nature and accuracy of the returned drug prices.
- Ask FastGPT a question about the cost-effectiveness of a specific drug. Check if the answer references the correct passages from the imported documents and if the cited data aligns with the original text.
