Tool Calling and Plugins for Nursing Management Products

Data Characteristics in Nursing Management

Nursing management data primarily consists of long-term patient health records and intervention plans. Data sources are diverse, including patient self-reports, smart wearable device monitoring, healthcare professional input, and synchronization with Hospital Information Systems (HIS). Updates are event-driven, such as each nursing visit, medication adjustment, abnormal physiological indicators, and periodic health assessment reports. Document structures typically include structured data (e.g., vital_signs, medication_log, follow_up_plan) and unstructured data (e.g., nursing_notes, patient_feedback). Fields include timestamps accurate to the second, numerical fields often with explicit units (e.g., mmHg, mmol/L, mg), and numerous enumeration type fields for nursing status or risk levels.

Constraints from These Characteristics on Tool Calling and Plugins

The highly structured nature and strict unit requirements of nursing management data demand high precision in tool calls. For example, querying medication records requires exact matching of drug names and dosage units to avoid confusion. The event-driven update mechanism means tools must consider time range limitations when querying data to retrieve nursing progress or abnormal events within a specific period. The presence of unstructured nursing logs requires tools to process free text, for example, by extracting keywords or recognizing entities to convert text information into a basis for structured queries. Additionally, data sensitivity mandates strict access control and data anonymization for tool calls to ensure patient privacy. This is particularly important when designing API_KEY or access_token transmission mechanisms.

Configuration Guidelines

Configuration Item	Suggested Value	Rationale for this Value
`maxContext`	`6000 tokens`	Ensures complete nursing plans, recent medications, and key physiological indicators are included, preventing context loss.
`tool_call_timeout`	`30 seconds`	Most internal services respond within 5-15 seconds; this provides a buffer for network fluctuations or complex queries.
`recall_top_k`	`5`	For nursing data recall specific to a patient, a small amount of precise data usually suffices for consultation.
`response_format`	`json_object`	Facilitates parsing structured data by downstream business systems, such as retrieving details for a specific `medication_id`.
`error_retries`	`2`	Allows limited retries to handle transient network issues or occasional backend service failures, improving stability.
`api_endpoint`	`https://api.care.example.com/v1`	Points to the internal nursing management system API, ensuring authoritative and real-time data sources.

Three Common Mistakes

400 Bad Request when calling external tools: This typically occurs because field names or data types in the request_body do not match the target API's definition. Examples include passing a string to a numerical field or missing a required field like patient_id.
Tool call returns empty or incomplete results: The query_params might be too broad or too narrow, failing to precisely match keywords in nursing logs, or the start_date and end_date for the time range are incorrect.
Context information in the workflow is not passed to the tool: This usually happens when context_variables are not mapped correctly in the workflow configuration, leading to the tool function receiving tool_args that lack necessary patient IDs or current nursing stage information.

How to Verify Configuration

Simulate patient inquiries for core nursing query scenarios. Observe if tool calls are triggered successfully and if the results contain expected key fields like medication_name and dosage.
Check the tool call logs in the FastGPT backend. Verify the request_url, request_body, and response_data for each call to ensure data transmission format and content meet expectations.
Construct inputs with abnormal conditions (e.g., non-existent patient ID, out-of-range dates). Test the tool's error handling mechanism to verify if it returns clear error_message or status_code.
