## 🔗 Integration Points

### How Inpatients Connects to Operating Theatre:

1. **Admission → SurgicalCase**
   ```python
   # In operating_theatre/models.py - SurgicalCase
   admission = models.ForeignKey(
       'inpatients.Admission',
       on_delete=models.SET_NULL,
       null=True,
       blank=True,
       related_name='surgical_cases'
   )
   ```

2. **Usage Example:**
   ```python
   # Get all surgeries for an admission
   admission = Admission.objects.get(pk=1)
   surgeries = admission.surgical_cases.all()
   
   # Check if surgery needs insurance approval
   for surgery in surgeries:
       if surgery.requires_approval():
           # Create approval request
           pass
   ```

3. **Operating Room Access:**
   ```python
   # Get all cases in an OR
   or_room = OperatingRoom.objects.get(room_number='OR-1')
   today_cases = or_room.surgical_cases.filter(
       scheduled_start__date=timezone.now().date()
   )
   ```

## 🎯 Next Steps (Recommended)

### Phase 1: Enhance Operating Theatre (Priority)
1. **Add Missing Status Choices to SurgicalCase:**
   - Add `CONFIRMED` status
   - Add `PREP` status

2. **Add Workflow Views:**
   - `confirm_case(request, pk)` - Confirm scheduled case
   - `prep_case(request, pk)` - Mark case in prep
   - `cancel_case(request, pk)` - Cancel case
   - `postpone_case(request, pk)` - Postpone case
   - `reschedule_case(request, pk)` - Reschedule case

3. **Add URL Patterns:**
   ```python
   path('cases/<int:pk>/confirm/', views.confirm_case, name='confirm_case'),
   path('cases/<int:pk>/prep/', views.prep_case, name='prep_case'),
   path('cases/<int:pk>/cancel/', views.cancel_case, name='cancel_case'),
   path('cases/<int:pk>/postpone/', views.postpone_case, name='postpone_case'),
   path('cases/<int:pk>/reschedule/', views.reschedule_case, name='reschedule_case'),
   ```

4. **Create Reschedule Template:**
   - `operating_theatre/templates/operating_theatre/case_reschedule.html`

### Phase 2: Update Data Generation
1. **Remove from `inpatients_data.py`:**
   - Remove SurgerySchedule data generation

2. **Verify `or_data.py`:**
   - Ensure SurgicalCase generation includes all statuses
   - Verify insurance approval integration

### Phase 3: Database Migration
1. **Create migrations:**
   ```bash
   python manage.py makemigrations
   python manage.py migrate
   ```

2. **Verify no broken references**

### Complete Status Flow:
```
SCHEDULED → CONFIRMED → PREP → IN_PROGRESS → COMPLETED
    ↓           ↓          ↓          ↓
POSTPONED   CANCELLED  DELAYED   CANCELLED
    ↓
SCHEDULED (via reschedule)
```
