AI-Assisted Features

This application uses AI-powered auto-correction technology to assist with HL7 v2 message validation. The auto-correction feature employs rule-based algorithms and pattern matching to identify and suggest corrections for common validation errors in HL7 v2 messages.

How Auto-Correction Works
  • Detection: The system analyzes validation errors reported by Gazelle EVS API
  • Analysis: Automated rules identify correctable issues based on HL7 v2.4 standards
  • Correction: Suggested fixes are applied to message segments, fields, and components
  • Validation: Corrected messages are re-validated iteratively until they pass or no more corrections are possible
Human Oversight & Control

You maintain full control: All auto-corrections are performed at your request. You can review validation reports, download corrected files, and verify all changes before submission. The system provides detailed reports showing what corrections were applied.

Limitations & Recommendations
⚠️ Important: While our auto-correction feature can fix many common errors, it may not resolve all validation issues. Always review corrected files and validation reports before submitting to production systems. This tool is designed to assist, not replace, human expertise in HL7 message development.
Data Privacy & Security

Your uploaded files and validation results are:

  • Stored securely in Microsoft Azure SQL Database with encryption
  • Accessible only to you via Azure AD authentication
  • Not used for training AI models or shared with third parties
  • Retained in your validation history for your reference
