## Technical Implementation Details

### Patient Search Functionality
```javascript
// Real-time patient search with AJAX
- Search by: MRN, name, phone, national ID
- Minimum 2 characters required
- Hospital filtering support
- Visual selection feedback
- Auto-fill caller/contact information
```

### Dynamic Form Loading
```javascript
// Hospital selection triggers:
1. Load departments for selected hospital
2. Load physicians for selected hospital
3. Filter patient search by hospital

// AJAX endpoints:
- /callcenter/ajax/departments/?hospital_id={id}
- /callcenter/ajax/physicians/?hospital_id={id}
- /callcenter/ajax/patients/?q={query}&hospital_id={id}
```

### Call Center Integration
```python
# Automatic call center interaction creation
CallCenterInteraction.objects.create(
    patient_id=patient_id,
    caller_name=caller_name,
    caller_phone=caller_phone,
    caller_relationship=caller_relationship,
    hospital_id=hospital_id,
    agent=request.user,
    call_type='complaint' or 'inquiry',
    subject=title/subject,
    notes=description/message,
    metadata={...}
)
```

### Audit Logging
```python
# All actions are logged
AuditService.log_event(
    event_type='complaint_created' or 'inquiry_created',
    description=f"...",
    user=request.user,
    content_object=complaint/inquiry,
    metadata={...}
)
```

# Applied in all views
if user.is_px_admin():
    pass  # See all
elif user.hospital:
    queryset = queryset.filter(hospital=user.hospital)
else:
    queryset = queryset.none()
```

## Performance Considerations

### Database Optimization
- `select_related()` for foreign keys
- `prefetch_related()` for reverse relationships
- Indexed fields for filtering
- Pagination to limit query results

### Frontend Optimization
- Debounced search input
- Lazy loading of departments/physicians
- Minimal AJAX requests
- Cached static assets

---

## Security Measures

### Input Validation
- Server-side validation for all inputs
- CSRF protection on all forms
- XSS prevention
- SQL injection prevention (Django ORM)

### Access Control
- Login required for all views
- RBAC enforcement
- Hospital/department filtering
- Audit trail for all actions

## Maintenance Notes

### Regular Maintenance Tasks
1. Monitor call center interaction logs
2. Review audit logs for compliance
3. Update SLA configurations as needed
4. Review and update complaint/inquiry categories
5. Monitor performance metrics
6. Update documentation as features evolve

### Troubleshooting
- **Patient search not working:** Check AJAX endpoint and hospital filter
- **Departments not loading:** Verify hospital selection and AJAX endpoint
- **Form submission fails:** Check required fields and validation
- **RBAC issues:** Verify user hospital assignment and permissions
