## Quick Start

### Analyze symptoms:

```python
from scripts.triage import analyze_symptoms
import os

# Set environment variables
os.environ["SKILL_BILLING_API_KEY"] = "your-api-key"
os.environ["SKILL_ID"] = "your-skill-id"

# Analyze patient symptoms
result = analyze_symptoms(
    symptoms="胸痛，呼吸困难，持续30分钟",
    age=65,
    gender="male",
    vital_signs={"bp": "160/95", "hr": 110, "temp": 37.2},
    user_id="user_123"
)

# Check result
if result["success"]:
    print("分诊等级:", result["triage"]["level"])
    print("紧急程度:", result["triage"]["urgency"])
    print("建议措施:", result["recommendations"])
else:
    print("错误:", result["error"])
    if "paymentUrl" in result:

## Triage Levels

| Level | Name | Response Time | Description | Examples |
|-------|------|---------------|-------------|----------|
| 1 | Resuscitation | Immediate | Life-threatening conditions requiring immediate intervention | Cardiac arrest, severe trauma, respiratory failure |
| 2 | Emergent | <15 min | High-risk conditions requiring rapid evaluation | Chest pain, severe bleeding, altered mental status |
| 3 | Urgent | <30 min | Serious conditions requiring timely medical attention | Abdominal pain, high fever, moderate trauma |
| 4 | Semi-Urgent | <60 min | Less acute conditions needing evaluation within hours | Minor injuries, chronic symptoms, stable conditions |
| 5 | Non-urgent | >60 min | Minor conditions that can wait days to weeks | Follow-up, prescription refill, administrative requests |
