## Usage Examples

### 1. WorkflowEngine
```python
from workflow_engine import WorkflowEngine, Task

engine = WorkflowEngine()

tasks = [Task(task_id="t1", name="Task 1", action=my_action, dependencies=[])]
engine.register_workflow("my_workflow", tasks)
execution = engine.execute_workflow("my_workflow", context={"data": "value"})
```

### 2. EHR-to-Podcast
```python
from ehr_to_podcast_workflow import EHRToPodcastWorkflow

workflow = EHRToPodcastWorkflow(engine)
result = workflow.execute("PATIENT_123", "ENCOUNTER_456")
# Returns: podcast script, audio metadata, QA validation
```

### 3. Sepsis Screening
```python
from diagnostic_workflows import DiagnosticWorkflows

diagnostics = DiagnosticWorkflows(engine)
result = diagnostics.screen_sepsis("PATIENT_789", vitals={
    'systolic_bp': 90, 'respiratory_rate': 24, 'heart_rate': 110,
    'temperature': 38.8, 'gcs': 14, 'wbc': 15.0
})
# Returns: risk_level, recommendations, alerts
```
