## Implementation Details
|
|
|
|
### 1. Consent Model Enhancements (`core/models.py`)
|
|
|
|
**Status:** ✅ **COMPLETE**
|
|
|
|
The Consent model already includes the `expiry_date` field with full functionality:
|
|
|
|
```python
|
|
class Consent(UUIDPrimaryKeyMixin, TimeStampedMixin, TenantOwnedMixin):
|
|
# ... existing fields ...
|
|
|
|
expiry_date = models.DateField(
|
|
null=True,
|
|
blank=True,
|
|
verbose_name=_("Expiry Date"),
|
|
help_text=_("Date when this consent expires and needs renewal")
|
|
)
|
|
|
|
@property
|
|
def is_expired(self):
|
|
"""Check if consent has expired."""
|
|
if not self.expiry_date:
|
|
return False
|
|
from datetime import date
|
|
return date.today() > self.expiry_date
|
|
|
|
@property
|
|
def days_until_expiry(self):
|
|
"""Calculate days until consent expires."""
|
|
if not self.expiry_date:
|
|
return None
|
|
from datetime import date
|
|
delta = self.expiry_date - date.today()
|
|
return delta.days
|
|
|
|
@property
|
|
def needs_renewal(self):
|
|
"""Check if consent needs renewal (within 30 days of expiry or expired)."""
|
|
if not self.expiry_date:
|
|
return False
|
|
days = self.days_until_expiry
|

## Celery Task Schedule
|
|
|
|

|
|
|
|
Add to `AgdarCentre/celery.py`:
|
|
|
|
```python
|
|
from celery.schedules import crontab
|
|
|
|
app.conf.beat_schedule = {
|
|
# ... existing tasks ...
|
|
|
|
# Consent Management Tasks
|
|
'check-expiring-consents-daily': {
|
|
'task': 'core.consent_tasks.check_expiring_consents',
|
|
'schedule': crontab(hour=8, minute=0), # 8:00 AM daily
|
|
},
|
|
'check-expired-consents-daily': {
|
|
'task': 'core.consent_tasks.check_expired_consents',
|
|
'schedule': crontab(hour=9, minute=0), # 9:00 AM daily
|
|
},
|
|
'generate-consent-expiry-report-weekly': {
|
|
'task': 'core.consent_tasks.generate_consent_expiry_report',
|
|
'schedule': crontab(day_of_week=1, hour=8, minute=0), # Monday 8:00 AM
|
|
},
|
|
'auto-deactivate-expired-consents-monthly': {
|
|
'task': 'core.consent_tasks.auto_deactivate_expired_consents',
|
|
'schedule': crontab(day_of_month=1, hour=2, minute=0), # 1st of month 2:00 AM
|
|
},
|
|
}
|
|
```
|
|
|
|
---
|
|
|
|
## API Integration
|
|
|
|
### Using Consent Management Service
|
|
|
|
```python
|
|
from core.consent_service import ConsentManagementService, ConsentNotificationService
|
|
from core.models import Patient, Consent, ConsentTemplate
|
|
|
|
# Check patient consent status
|
|
patient = Patient.objects.get(mrn='MRN-001')
|
|
status = ConsentManagementService.check_patient_consent_status(patient)
|
|
|
|
if not status['has_valid_consent']:
|
|
print(f"Missing consents: {status['missing_types']}")
|
|
print(f"Expired consents: {status['expired_consents']}")
|
|
|
|
# Get expiring consents for tenant
|
|
from core.models import Tenant
|
|
tenant = Tenant.objects.get(code='AGDAR')
|
|
expiring = ConsentManagementService.get_expiring_consents(tenant, days_threshold=30)
|
|
|
|
for consent_info in expiring:
|
|
print(f"Patient {consent_info['patient_mrn']} - {consent_info['days_remaining']} days left")
|
|
|
|
# Create consent from template
|
|
template = ConsentTemplate.objects.get(consent_type='GENERAL_TREATMENT', is_active=True)
|
|
consent = ConsentManagementService.create_consent_from_template(
|
|
patient=patient,
|
|
template=template,
|
|
expiry_days=365,
|
|
language='en'
|
|
)
|
|
|
|
# Renew expired consent
|
|
old_consent = Consent.objects.get(id='consent-uuid')
|
|
new_consent = ConsentManagementService.renew_consent(old_consent, expiry_days=365)
|
|
|
|
# Validate before booking
|
|
is_valid, missing = ConsentManagementService.validate_consent_before_booking(patient)
|
|
if not is_valid:
|
|
print(f"Cannot book: Missing {missing}")
|
|
|
|
# Get statistics
|
|
stats = ConsentManagementService.get_consent_statistics(tenant)
|
|
print(f"Total active: {stats['total_active']}")
|
|
print(f"Expiring in 30 days: {stats['expiring_30_days']}")
|
|
print(f"Expired: {stats['expired']}")
|
|
```
|
|
|
|
### Using Consent Notification Service
|
|
|
|
```python
|
|
from core.consent_service import ConsentNotificationService
|
|
|
|
# Send expiry reminder
|
|
consent = Consent.objects.get(id='consent-uuid')
|
|
ConsentNotificationService.send_expiry_reminder(consent)
|
|
|
|
# Send expired notification
|
|
ConsentNotificationService.send_expired_notification(consent)
|
|
|
|
# Notify reception staff
|
|
expired_list = ConsentManagementService.get_expired_consents(tenant)
|
|
ConsentNotificationService.notify_reception_expired_consents(tenant, expired_list)
|
|
```
|
|
|
|
---
|
|
|
|
## Consent Lifecycle
|
|
|
|
### 1. Creation
|
|
```
|
|
Template → Populate with Patient Data → Create Consent → Set Expiry Date
|
|
```
|
|
|
|
### 2. Active Period
|
|
```
|
|
Active → Monitor Expiry → Send Reminders (30/14/7 days)
|
|
```
|
|
|
|
### 3. Expiry
|
|
```
|
|
Expired → Notify Patient/Staff → Block Appointments → Require Renewal
|
|
```
|
|
|
|
### 4. Renewal
|
|
```
|
|
Old Consent (Deactivate) → New Consent (Version++) → New Expiry Date
|
|
```
|
|
|
|
### 5. Archival
|
|
```
|
|
Expired >90 days → Auto-Deactivate → Historical Record
|
|
```
|
|
|

|
|
|
|

|
|--------------------|--------|------------|
|
|
| 30 days | First reminder | Patient/Caregiver (Email + SMS) |
|
|
| 14 days | Second reminder | Patient/Caregiver (Email + SMS) |
|
|
| 7 days | Final reminder | Patient/Caregiver (Email + SMS) |
|
|
| 0 days (Expired) | Expired notification | Patient/Caregiver + Reception Staff |
|
|
| Weekly | Summary report | Administrators |

|
## Performance Considerations
|
|
|
|
### Database Indexes
|
|
|
|
All critical queries are optimized with indexes:
|
|
- `Consent.patient_id, consent_type` - Indexed for status checks
|
|
- `Consent.expiry_date` - Indexed for expiry queries
|
|
- `Consent.is_active` - Indexed for active consent queries
|
|
|
|
### Query Optimization
|
|
|
|
- Uses `select_related()` for patient relationships
|
|
- Filters at database level before Python processing
|
|
- Batch processing for notifications
|
|
- Efficient date range queries
|
|
|
|
### Caching Recommendations
|
|
|
|
Consider caching for:
|
|
- Patient consent status (cache for 1 hour)
|
|
- Consent statistics (cache for 30 minutes)
|
|
- Template versions (cache for 1 day)
|
|
|
|
---
|
|
|
|
## Security Considerations
|
|
|
|
### Data Protection
|
|
|
|
- Consent content encrypted at rest
|
|
- Signature hash verification
|
|
- IP address tracking for signatures
|
|
- Audit trails for all changes
|
|
- Historical records maintained
|
|
|
|
### Access Control
|
|
|
|
- Only authorized staff can create/renew consents
|
|
- Patients can view their own consents
|
|
- Reception can check consent status
|
|
- Administrators can manage templates
|
|
|
|
