Model Integration and Configuration for Care Management

Data Characteristics in Care Management

Care management products integrate diverse data sources. These primarily include Electronic Medical Records (EMR), nursing notes, vital sign monitoring devices, patient self-reported questionnaires, and admission/discharge assessment forms. Data updates frequently; vital signs, for example, may update hourly or even minutely. Document structures include both structured table data (e.g., patient demographics, medication records) and extensive unstructured text (e.g., nursing logs, physician diagnoses, patient communication records). Fields include patient ID, care plan ID, operation time, nursing staff, vital signs (blood pressure, heart rate, temperature), medication dosage, and assessment results. Units involve time units (hours, days), numerical units (mmHg, beats/min, °C, mg), and textual descriptions.

Constraints from Data Characteristics on Model Integration and Configuration

The diversity and high update frequency of care management data impose specific requirements on model integration. The large volume of unstructured text necessitates efficient text parsing and embedding capabilities to capture critical information and potential risk points from nursing logs. The mix of structured and unstructured data requires models to process both data types simultaneously and establish effective connections. High-frequency data, particularly vital signs, demands real-time or near real-time index update mechanisms in model configuration to ensure knowledge base timeliness. Furthermore, differing fields and units across data sources require standardization during data preprocessing to prevent model interpretation biases. For instance, blood pressure units might require conversion between kPa and mmHg, and temperature might require conversion between Celsius and Fahrenheit.

Configuration Guidelines

Configuration Item	Recommended Value	Rationale
`chunk_size`	`800–1200 characters`	Nursing records and assessment texts often contain lengthy narratives. This length helps preserve contextual integrity and prevents critical information from being truncated.
`overlap_size`	`100–200 characters`	Ensures sufficient overlap between chunks, improving recall and reducing semantic loss due to chunk boundaries.
`maxContext`	`16384 tokens`	Care consultations often require referencing multiple records. A larger context window accommodates more historical data for comprehensive analysis.
`embedding_model`	`text-embedding-ada-002` or `deepseek-v2`	Balances semantic understanding capabilities with cost-effectiveness, suitable for handling the complexity of medical texts.
`recall_top_k`	`8–12 entries`	Considering the complexity of nursing scenarios, increasing the recall quantity ensures coverage of multiple highly relevant pieces of information.
`sync_interval_minutes`	`60 minutes`	Addresses the high update frequency of vital signs, nursing logs, and other data, ensuring knowledge base timeliness.

Common Pitfalls

Poor knowledge base query relevance and inaccurate generated answers. This occurs when chunk_size is set too small or too large, leading to unreasonable text segmentation, loss of context, or introduction of excessive irrelevant information.
Suboptimal model response timeliness or inability to retrieve the latest nursing records. This occurs when the knowledge base synchronization configuration sync_interval_minutes is too long, failing to update the latest patient data promptly.
404 Not Found errors when integrating third-party models. This occurs due to incorrect API_KEY or BASE_URL configuration, or if the selected model is unavailable in the current service region.

Validation Steps

Use FastGPT's test chat function to ask typical care consultation questions. Observe if the model accurately references information from the knowledge base, such as care plans and medication records.
Check knowledge base synchronization logs. Confirm that data sources update successfully at the configured sync_interval_minutes frequency and that no parsing failures are recorded.
Utilize FastGPT's knowledge base preview function. Verify if different types of care data (structured, unstructured) are correctly segmented and indexed. Pay particular attention to the extraction of key fields like operation time and vital signs.
Select a patient with recent data updates and conduct relevant consultations. Evaluate if the model's answers include the latest nursing records and vital sign data, and compare them against actual data to confirm timeliness.
