Tool Calling and Plugins for Infectious Disease Clinical Trial Pre-screening

Infectious disease clinical trial pre-screening involves diverse data types. These primarily include patient medical records, laboratory test results

Data Characteristics in this Category

Infectious disease clinical trial pre-screening involves diverse data types. These primarily include patient medical records, laboratory test results, imaging reports, and microbiology test data. This data typically originates from Hospital Information Systems (HIS), Laboratory Information Systems (LIS), and Electronic Health Record (EHR) systems. Data update frequency varies by type. For instance, vital signs and some laboratory indicators may update multiple times daily, while microbiology culture results and genetic sequencing data might take days to weeks. Regarding document structure, patient medical records are often unstructured or semi-structured text, containing chief complaints, history of present illness, past medical history, and medication history. Laboratory and imaging data are usually structured in tabular form, with standardized test items, values, and units. Microbiology test results include specific fields like strain names and antimicrobial susceptibility results. Some data sources may also provide sequence data.

Constraints Imposed by these Features on "Tool Calling and Plugins"

The high timeliness requirement of infectious disease data necessitates low-latency processing capabilities for tool calls to ensure real-time pre-screening results. Processing unstructured medical record data requires robust Natural Language Understanding (NLU) capabilities to accurately extract key clinical information. Specific fields in microbiology test results, such as MIC values (Minimum Inhibitory Concentration) or antibiotic sensitivity, require plugins to precisely identify and perform logical judgments. The heterogeneity of data sources demands that tool calls adapt to various API interfaces and data formats, such as HL7, FHIR, or custom JSON structures. Furthermore, due to the rapid progression of infectious diseases, historical data version management and traceability capabilities are factors to consider in plugin design to support dynamic adjustment of pre-screening conditions.

Configuration Guidelines

Configuration ItemSuggested ValueRationale
API_TIMEOUT_SECONDS30 secondsEnsures timely response for clinical data with high real-time requirements.
MAX_RETRIES_ON_FAILURE3 timesAddresses temporary network fluctuations or momentary service unavailability.
TEXT_EMBEDDING_MODELtext-embedding-ada-002Suitable for biomedical text semantic understanding.
CHUNK_SIZE800–1200 charactersBalances semantic completeness of long texts with retrieval efficiency.
SIMILARITY_THRESHOLD0.75–0.85Filters for patient information highly relevant to pre-screening conditions.
MICROBE_IDENTIFIER_REGEXCalibrated by actual testsAccurately matches microbial names and associated antimicrobial susceptibility fields.

Three Common Pitfalls

  • When calling external services, the frontend experiences data interruption, and page content becomes static. This is often due to mishandling of the Connection: close header by an intermediary service, failing to correctly pass Transfer-Encoding: chunked.
  • When configuring plugins, failing to specify API_KEY or SECRET leads to external API authentication failure, returning an HTTP 401 Unauthorized error.
  • When parsing microbiology test reports, the MIC value or antibiotic sensitivity field is empty. This occurs because the regular expression matching is inaccurate, failing to cover all possible field names or format variations in the report.

How to Verify Proper Configuration

  • Use the FastGPT debugging interface to send simulated requests to the configured plugin. Verify that the returned HTTP status code is 200 OK and that the response body structure matches expectations.
  • Run the pre-screening process using a test set containing typical infectious disease clinical data. Check if strain name, antibiotic name, and antimicrobial susceptibility results are accurately extracted in the output.
  • Check the plugin logs for API call time records. Ensure that single call duration meets the API_TIMEOUT_SECONDS setting to satisfy real-time requirements.
  • Adjust the SIMILARITY_THRESHOLD parameter and run tests multiple times. Observe the change in the number of recalled patient records to determine an appropriate threshold range.
