🏗️ How It Works

Step-by-Step Flow

Doctor clicks "Export PDF" button
- Button located in top-right corner of patient info
System validates permissions
- Checks if user has patient.read permission
- Doctor role ✅ has this permission
- Other roles ❌ will get permission denied
Patient data is gathered
- EMR records (diagnoses, symptoms, vitals, notes)
- Prescriptions (medications, dosages, instructions)
- Lab tests (types, results, status)
- Appointments (dates, reasons, status)
PDF is generated
- jsPDF library creates PDF object
- Formats data with professional styling
- Adds page breaks as needed
- Compresses content
Download is triggered
- Browser's download manager opens
- File saves to Downloads folder
- File name: EMR_[LastName]_[FirstName]_[Date].pdf
Audit log is created
- Records doctor ID, patient ID, timestamp
- Stores doctor name, patient name
- Available for compliance review

🔒 Security & Compliance

Permission Model

Feature requires: patient.read permission
Who has it: DOCTOR role (21 permissions total)
Who doesn't: NURSE, PHARMACIST, LAB_TECH, etc. (different permissions)

Audit Trail

Every PDF export creates a database record:

{

  resource: "Patient",
  actorId: "doctor-unique-id",
  resourceId: "patient-unique-id",
  meta: {
    patientName: "John Doe",
    exportedBy: "Dr. Jane Smith",
    exportedAt: "2024-01-25T10:30:00Z"
  },
  createdAt: "2024-01-25T10:30:00Z"
}

HIPAA Compliance

✅ Data Residency: Data never leaves hospital system ✅ Encryption: No external transmission needed ✅ Authentication: Session-based validation ✅ Authorization: Role-based permission checks ✅ Audit: Complete export audit trail maintained ✅ Access Control: Doctor-specific records only

⚙️ Configuration & Customization

Change Button Text

Edit src/components/doctor/patient-detail.tsx:

<Button>
  <Download className="w-4 h-4 mr-2" />
  Download EMR  // Change this text
</Button>

Change PDF Colors

Edit src/lib/pdf-generator.ts:

const primaryColor = [41, 128, 185];    // Main color (RGB)
const headerColor = [230, 240, 250];    // Header background
const borderColor = [200, 200, 200];    // Borders

Change Filename Format

Edit src/lib/pdf-generator.ts:

// Default:
const fileName = `EMR_${patient.lastName}_${patient.firstName}_${date}.pdf`;

// Alternative options:
const fileName = `Patient_${patientId}_${Date.now()}.pdf`;
const fileName = `EMR_Report_${new Date().toISOString().split('T')[0]}.pdf`;

Add Custom Sections

Edit src/lib/pdf-generator.ts to add new sections:

// After line ~200, add:
if (patient.allergies) {
  addSection('ALLERGIES');
  patient.allergies.forEach((allergy) => {
    addKeyValue(allergy.name, allergy.severity);
  });
}

🐛 Troubleshooting

Issue: Button Not Visible

Causes:

Dev server not restarted
Next.js cache not cleared
Component not updated

Solutions:

# Restart server
npm run dev

# Or clear cache and restart
rm -rf .next
npm run dev

# Hard refresh browser: Ctrl+Shift+R

Issue: PDF Not Downloading

Causes:

Pop-up blocker enabled
Browser settings blocking downloads
File system permissions issue

Solutions:

Disable pop-up blocker for localhost
Check browser download settings
Try different browser
Check browser console for errors (F12)

Issue: Permission Denied Error

Causes:

User not a Doctor
Session expired
Permissions not properly assigned

Solutions:

# Check user permissions in database:
SELECT u.email, r.name, rp.permission_id 
FROM user u 
LEFT JOIN roleEntity r ON u.roleEntityId = r.id
LEFT JOIN rolePermission rp ON r.id = rp.roleId
WHERE u.id = 'user-id';

# Or check via Admin RBAC UI:
1. Go to Admin → RBAC
2. Click Users tab
3. Find user, verify role is DOCTOR
4. Verify role has patient.read permission

Issue: Empty PDF Generated

Causes:

Patient has no records
Data loading issue
Query returning null

Solutions:

Create sample EMR for patient (EMR tab → New EMR)
Create sample prescription (Prescriptions tab → New Rx)
Try different patient with existing data
Check browser console for errors

Issue: Slow Export Performance

Causes:

Patient has 500+ records (normal)
Browser running low on memory
Large text/notes in records

Solutions:

This is expected for large datasets
Use different browser if too slow
Close other tabs to free memory
Consider archiving old records
