Implementation Guides

Welcome to the Nuxera Implementation Guides. This section provides best practices and step-by-step tutorials to help you integrate Nuxera APIs into your healthcare applications.

Available Guides

Here you'll find comprehensive guides for implementing various features of the Nuxera platform:

Getting Started

To get started with Nuxera implementation, we recommend following these steps:

  1. Set up Authentication: Review the Authentication section to set up your API credentials and understand the authentication flow.
  2. Understand API Structure: Familiarize yourself with our API overview to understand the available endpoints and data structures.
  3. Choose Your Integration Path: Decide whether you need Transcription, Dictation, or both services.
  4. Implement Audio Handling: Learn how to properly manage audio files in your application.
  5. Test Your Integration: Use our sandbox environment to validate your implementation before going live.

Authentication Setup

Proper authentication is critical for secure API usage. Follow these steps to implement authentication:

  1. Obtain API Credentials:

    • Register your application in the Nuxera Developer Portal
    • Generate API keys for both development and production environments

  2. Implement Token-Based Authentication:

    // Example authentication request
const response = await fetch('https://api.nuxera.ai/v1/auth/token', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    client_id: 'YOUR_CLIENT_ID',
    client_secret: 'YOUR_CLIENT_SECRET',
  }),
});

const { access_token, expires_in } = await response.json();

  3. Secure Token Storage:

    • Store tokens securely in server-side code, never in client-side JavaScript
    • Implement token refresh mechanism before expiration (typical token validity is 1 hour)

For complete authentication details, see our Authentication Documentation.

Transcription Implementation

Implementing the transcription service allows you to convert medical consultations into text:

  1. Audio Capture Setup:

    • Implement high-quality audio recording in your application
    • Use recommended audio formats: WAV or MP3 at 16kHz or higher sampling rate
    • Ensure proper noise cancellation during recording

  2. API Integration:

    // Example transcription request
const formData = new FormData();
formData.append('audio', audioBlob);
formData.append('language', 'en-US');
formData.append('medical_specialty', 'cardiology');

const response = await fetch('https://api.nuxera.ai/v1/transcription', {
  method: 'POST',
  headers: {
    Authorization: `Bearer ${access_token}`,
  },
  body: formData,
});

const result = await response.json();

  3. Handling Responses:

    • Process the returned transcription text
    • Display the structured information (ICD-10 codes, medications, procedures)
    • Implement a review interface for physicians to verify and edit transcriptions

For detailed implementation guides, see our Transcription API Documentation.

Dictation Integration

The dictation service allows healthcare providers to record clinical notes for processing:

  1. Dictation Workflow Implementation:

    • Add dictation recording capabilities to your application
    • Implement start/stop functionality with visual feedback
    • Provide audio review before submission

  2. API Integration:

    // Example dictation request
const formData = new FormData();
formData.append('audio', dictationBlob);
formData.append('provider_id', 'PROVIDER_123');
formData.append('patient_id', 'PATIENT_456');
formData.append('encounter_type', 'follow_up');

const response = await fetch('https://api.nuxera.ai/v1/dictation', {
  method: 'POST',
  headers: {
    Authorization: `Bearer ${access_token}`,
  },
  body: formData,
});

const result = await response.json();

  3. Post-Processing:

    • Store dictation results in your EHR system
    • Implement review workflows for transcribed dictations
    • Enable editing and signing of clinical notes

For complete details, refer to our Dictation API Documentation.

Audio Management

Proper audio management is crucial for accurate transcription and dictation results:

  1. Audio Quality Guidelines:

    • Recommended formats: WAV (16-bit PCM), MP3 (128kbps or higher)
    • Sampling rate: 16kHz or higher
    • Channels: Mono preferred for voice recognition

  2. Handling Large Files:

    • Implement chunked uploads for files larger than 10MB
    • Use our resumable upload API for very large recordings
    • Consider server-side processing for web applications

  3. Audio Preprocessing:

    • Implement noise reduction when possible
    • Normalize audio levels before sending
    • Remove long silences to optimize processing

For detailed audio handling best practices, see our Audio Management Documentation.

Data Processing and Analysis

After receiving transcription or dictation results, proper data processing is essential:

  1. Structured Data Extraction:

    • Parse and validate ICD-10 codes
    • Extract medication information including dosages
    • Identify procedure codes and lab values

  2. Integration with EHR Systems:

    • Map Nuxera data structures to your EHR fields
    • Implement proper error handling for field mapping
    • Create validation rules for data import

  3. Analytics Implementation:

    • Track transcription accuracy metrics
    • Monitor dictation usage patterns
    • Implement feedback loops for AI improvement

FHIR Integration

Nuxera supports FHIR (Fast Healthcare Interoperability Resources) for standardized healthcare data exchange:

  1. FHIR Resource Mapping:

    • Map transcription results to FHIR Observation resources
    • Create DocumentReference resources for dictations
    • Link resources to proper Patient and Encounter contexts

  2. Implementation Example:

    // Example of creating a FHIR DocumentReference from a transcription
const fhirResource = {
  resourceType: 'DocumentReference',
  status: 'current',
  docStatus: 'final',
  type: {
    coding: [
      {
        system: 'http://loinc.org',
        code: '34109-9',
        display: 'Note',
      },
    ],
  },
  subject: {
    reference: `Patient/${patientId}`,
  },
  content: [
    {
      attachment: {
        contentType: 'text/plain',
        data: btoa(transcriptionResult.text),
        title: 'Clinical Note',
      },
    },
  ],
};

  3. FHIR Server Integration:

    • Implement proper authentication with your FHIR server
    • Handle version management for resource updates
    • Implement error handling for FHIR transactions

Security and Compliance

Security is paramount when handling protected health information (PHI):

  1. HIPAA Compliance Measures:

    • Encrypt all data in transit and at rest
    • Implement proper access controls and audit logging
    • Establish Business Associate Agreements when required

  2. Data Retention Policies:

    • Configure appropriate retention periods for audio and transcripts
    • Implement secure data deletion processes
    • Document your data handling procedures

  3. Security Best Practices:

    • Regularly rotate API credentials
    • Implement IP whitelisting for API access
    • Use TLS 1.2 or higher for all communications

Performance Optimization

For optimal system performance, consider these recommendations:

  1. Request Optimization:

    • Batch small requests when possible
    • Implement proper request throttling
    • Use compression for large payloads

  2. Response Handling:

    • Implement proper caching strategies
    • Process responses asynchronously for long-running tasks
    • Set up webhooks for notification of completed tasks

  3. Error Handling:

    • Implement exponential backoff for retries
    • Log detailed error information for troubleshooting
    • Set up monitoring alerts for API failures
