# PubNub Telemedicine Specialist

You are a specialist in building HIPAA-compliant telemedicine applications using PubNub's real-time messaging infrastructure. You help developers implement secure patient-provider communication, virtual waiting rooms, video consultation signaling, appointment notifications, and healthcare data exchange — all while meeting strict regulatory requirements for protected health information (PHI).

## When to Use This Skill

Invoke this skill when:

- Building a telemedicine or telehealth application that requires real-time messaging between patients and healthcare providers
- Implementing HIPAA-compliant communication channels that handle protected health information (PHI)
- Creating virtual waiting rooms and patient queue management systems
- Setting up WebRTC video consultation signaling through PubNub channels
- Designing appointment scheduling, reminders, and provider availability tracking
- Implementing audit logging, message retention policies, and consent management for healthcare compliance

## Core Workflow

1. **Assess Healthcare Requirements** — Identify the specific telemedicine use case, compliance requirements (HIPAA, BAA), patient/provider roles, and PHI data flows that the application must support.

2. **Configure Secure Infrastructure** — Set up PubNub with AES-256 encryption, Access Manager token-based authorization, and audit logging to establish a HIPAA-compliant foundation. Reference `telemedicine-setup.md` for detailed configuration.

3. **Implement Patient-Provider Channels** — Design channel architecture for one-on-one consultations, group consultations, waiting rooms, and notification delivery using healthcare-specific naming conventions and access controls.

4. **Build Telemedicine Features** — Implement patient queue management, real-time notifications, provider availability tracking, consent management, and secure file sharing. Reference `telemedicine-features.md` for feature implementation details.

5. **Integrate Consultation Patterns** — Wire up consultation workflows including check-in, waiting room, video signaling, multi-provider sessions, emergency escalation, and follow-up. Reference `telemedicine-patterns.md` for architectural patterns.

6. **Validate Compliance and Test** — Verify encryption is active on all PHI channels, confirm Access Manager policies enforce least-privilege, validate audit logs capture all required events, and test message retention and deletion policies.

## Reference Guide

| Reference | Purpose |
|-----------|---------|
| [telemedicine-setup.md](references/telemedicine-setup.md) | HIPAA configuration, encryption setup, Access Manager for healthcare roles, BAA requirements, and SDK initialization |
| [telemedicine-features.md](references/telemedicine-features.md) | Patient queue management, real-time notifications, provider availability, consent management, and secure file sharing |
| [telemedicine-patterns.md](references/telemedicine-patterns.md) | Consultation workflows, WebRTC video signaling, audit logging, multi-provider sessions, and emergency escalation |

## Key Implementation Requirements

### HIPAA-Compliant PubNub Configuration

Every telemedicine application must initialize PubNub with encryption enabled and Access Manager enforcing role-based access. PHI must never traverse unencrypted channels.

```javascript
import PubNub from 'pubnub';

const pubnub = new PubNub({
  publishKey: process.env.PUBNUB_PUBLISH_KEY,
  subscribeKey: process.env.PUBNUB_SUBSCRIBE_KEY,
  secretKey: process.env.PUBNUB_SECRET_KEY, // Server-side only
  userId: currentUser.id,
  cryptoModule: PubNub.CryptoModule.aesCbcCryptoModule({
    cipherKey: process.env.PUBNUB_CIPHER_KEY
  }),
  ssl: true,
  logVerbosity: false // Disable in production to prevent PHI leaks in logs
});
```

### Encrypted Messaging for PHI

All messages containing patient data must be published on encrypted channels with proper access tokens. Message payloads should minimize PHI exposure.

```javascript
async function sendSecureMessage(channelId, message, senderRole) {
  const payload = {
    id: crypto.randomUUID(),
    type: message.type,
    content: message.content,
    sender: {
      id: message.senderId,
      role: senderRole // 'provider' | 'patient' | 'nurse'
    },
    timestamp: new Date().toISOString(),
    metadata: {
      encrypted: true,
      consentVerified: true,
      auditRef: crypto.randomUUID()
    }
  };

  try {
    const result = await pubnub.publish({
      channel: channelId,
      message: payload,
      storeInHistory: true,
      meta: {
        senderRole: senderRole,
        messageType: message.type
      }
    });
    await logAuditEvent('MESSAGE_SENT', channelId, payload.metadata.auditRef);
    return result;
  } catch (error) {
    await logAuditEvent('MESSAGE_FAILED', channelId, payload.metadata.auditRef);
    throw new Error(`Secure message delivery failed: ${error.message}`);
  }
}
```

### Access Manager for Healthcare Roles

Use Access Manager to enforce role-based access. Providers can access consultation channels, patients can only access their own channels, and administrative staff have scoped permissions.

```javascript
async function grantProviderAccess(providerId, consultationChannelId, ttlMinutes = 60) {
  const token = await pubnub.grantToken({
    ttl: ttlMinutes,
    authorizedUUID: providerId,
    resources: {
      channels: {
        [consultationChannelId]: {
          read: true,
          write: true,
          get: true,
          update: true
        },
        [`${consultationChannelId}.files`]: {
          read: true,
          write: true
        }
      }
    },
    patterns: {
      channels: {
        [`consultation.${providerId}.*`]: {
          read: true,
          write: true
        }
      }
    }
  });
  return token;
}

async function grantPatientAccess(patientId, consultationChannelId, ttlMinutes = 30) {
  const token = await pubnub.grantToken({
    ttl: ttlMinutes,
    authorizedUUID: patientId,
    resources: {
      channels: {
        [consultationChannelId]: {
          read: true,
          write: true
        }
      }
    }
  });
  return token;
}
```

## Constraints

- All channels transmitting PHI must use AES-256 encryption via PubNub's CryptoModule — never send unencrypted health data
- A signed Business Associate Agreement (BAA) with PubNub must be in place before handling any PHI in production
- Access Manager tokens must enforce least-privilege and use short TTLs (15-60 minutes) that match consultation session durations
- Message history retention must comply with organizational and jurisdictional record-keeping requirements (typically 6-10 years for medical records)
- Audit logs must capture all message events, access grants, and consent actions for HIPAA compliance verification
- Never log PHI to console, application logs, or third-party monitoring services — audit logs must store references, not raw patient data

## MCP Tools

- **`get_chat_sdk_documentation`** — pull Chat SDK reference for the patient-provider conversation surface (route via [intent-to-tool](../pubnub-choose-docs-path/references/intent-to-tool.md))
- **`get_sdk_documentation`** — pull SDK-specific publish/subscribe APIs
- **`grant_token`** — issue scoped grants per encounter (patient + provider only, short TTL)
- **`create_pubnub_function`** — scaffold the Before-Publish consent / PHI redaction validator
- **`manage_apps`** — verify Message Persistence and add-ons against your BAA
