The Consent model already includes the expiry_date field with full functionality:

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
        return days is not None and days <= 30

Celery Task Schedule

Recommended Celery Beat Configuration

Add to AgdarCentre/celery.py:

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

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

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

Notification Timeline

Days Before Expiry Action Recipients
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

Testing Checklist

Unit Tests Needed

  • Test check_patient_consent_status() with various scenarios
  • Test get_expiring_consents() with different thresholds
  • Test get_expired_consents() accuracy
  • Test create_consent_from_template() with bilingual content
  • Test renew_consent() version increment
  • Test validate_consent_before_booking() validation logic
  • Test get_consent_statistics() calculations
  • Test consent expiry property calculations
  • Test consent needs_renewal logic

Integration Tests Needed

  • Test appointment booking with expired consent (should fail)
  • Test appointment booking with valid consent (should succeed)
  • Test expiry reminder task execution
  • Test expired consent task execution
  • Test weekly report generation
  • Test auto-deactivation of old consents
  • Test notification delivery to patients
  • Test notification delivery to staff

Manual Testing

  • Create consent with expiry date
  • Verify expiry reminders sent at 30/14/7 days
  • Verify expired notification sent on expiry
  • Verify reception staff notified of expired consents
  • Verify appointment booking blocked with expired consent
  • Verify consent renewal workflow
  • Verify version control working
  • Verify weekly report generation and delivery

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

Future Enhancements (Optional)

Potential Additions

  1. Digital Signature Integration

    • E-signature provider integration (DocuSign, etc.)
    • Biometric signature capture
    • Advanced signature verification

  2. Consent Analytics

    • Consent completion rates
    • Average time to sign
    • Expiry prediction models

  3. Multi-Language Support

    • Additional language templates
    • Automatic language detection
    • Translation services integration

  4. Mobile App Integration

    • Mobile consent signing
    • Push notifications for expiry
    • QR code consent access

  5. Advanced Workflows

    • Multi-step consent approval
    • Witness signature requirements
    • Legal representative workflows

Documentation Updates Needed

  • Reception Staff Consent Checklist
  • Administrator Consent Template Guide

Developer Documentation

  • Consent Service API Reference
