Paediatric acute triage sign extraction schema for MESA

Paedacuteschema

Schema package for extracting acute triage signs ("red flags") from paediatric triage notes.

Lightweight by design: a single flat AcuteSignType enum whose members are the canonical feature tokens consumed by downstream ML pipelines. Synonym/lay-phrasing guidance for matching lives in the prompt templates rather than the enum itself.

Structure

📁 paedacuteschema
├── examples/            # Training examples showing document input and structured output
├── schema.py            # Pydantic model for specifying expected output structure
├── prompt_builder.py    # Prompt builder for data generation and inference

Usage

from paedacuteschema.prompt_builder import PromptBuilder

# Initialize builder
builder = PromptBuilder()

# Build data generation prompt (with example)
datagen_prompt = builder.build_datagen_prompt()

# Build main/inference prompt (without example)
main_prompt = builder.build_main_prompt()
