How to Build a Patient Portal from Scratch

Introduction

A patient portal is the digital front door to your healthcare practice. It empowers patients to access their medical information, schedule appointments, communicate with providers, and manage their healthcare needs 24/7.

This guide will show you how to build a comprehensive patient portal that increases engagement, reduces administrative burden, and improves patient satisfaction.

What You’ll Learn

Step 2: Design for Mobile

73% of patients access portals from mobile devices. Your portal must be mobile-first.

Mobile Design Principles

• Large Touch Targets: Buttons should be minimum 44x44 pixels
• Simple Navigation: Max 5 primary menu items
• Minimal Text Input: Use selection whenever possible
• Fast Load Times: Optimize images and code
• Offline Capability: Cache key information

Example Mobile-First Layout

<nav class="bottom-navigation">
  <button>Home</button>
  <button>Appointments</button>
  <button>Messages</button>
  <button>Records</button>
  <button>More</button>
</nav>

Step 3: Implement Security

Security isn’t optional—it’s mandatory.

Authentication

// Example: Multi-factor authentication
async function loginWithMFA(email, password, mfaCode) {
  // Verify password
  const user = await verifyCredentials(email, password);

  // Verify MFA code
  const mfaValid = await verifyMFACode(user.id, mfaCode);

  if (mfaValid) {
    return generateSecureSession(user);
  }

  throw new Error('Invalid credentials');
}

Data Encryption

• In Transit: TLS 1.3
• At Rest: AES-256
• Backups: Encrypted and tested regularly

Access Controls

• Role-based permissions
• Audit logging
• Session timeouts
• IP restrictions (optional)

Step 4: Build Key Features

Appointment Scheduling

Users should be able to book appointments in 3 clicks or less:

1. Select provider or service
2. Choose date and time
3. Confirm

// Simple booking flow
function BookingFlow() {
  const [step, setStep] = useState(1);
  const [booking, setBooking] = useState({});

  return (
    <div>
      {step === 1 && <ProviderSelect onSelect={handleProviderSelect} />}
      {step === 2 && <DateTimeSelect onSelect={handleDateSelect} />}
      {step === 3 && <BookingConfirm booking={booking} />}
    </div>
  );
}

Medical Records Display

Present information in digestible chunks:

• Use tabs to separate record types
• Show most recent first
• Provide clear labels and explanations
• Allow downloading/printing

Secure Messaging

Key requirements:

• End-to-end encryption
• Delivery and read receipts
• Auto-save drafts
• Attachment support
• Provider response time expectations

• FHIR APIs: Modern standard for healthcare data exchange

Common Integration Points

• Appointment scheduling
• Lab results
• Medication lists
• Visit summaries
