- **Condition**: Diagnoses and medical problems
- **Observation**: Vital signs, lab results, measurements
- **Medication**: Drug information and prescriptions
- **Procedure**: Surgical and medical procedures
- **AllergyIntolerance**: Drug and environmental allergies

### 3.3 Data Exchange Protocol

```
1. Patient authorization (biometric or token-based)
2. Facility submits verified access request
3. Multi-party verification (2 of 4 trust anchors)
4. Encrypted medical record transmission
5. Facility decrypts and accesses data
6. All access logged on blockchain
7. Patient notification of data access
```

### 3.4 Emergency Access

In medical emergencies where consent cannot be obtained:
- Emergency override requires 2 physician authorization
- Access limited to critical information (allergies, blood type, current medications)
- Automatic patient notification when conscious
- Enhanced audit trail and review process
