PX360 Final Implementation Summary

Project: Patient Experience 360 Management System
Client: AlHammadi Group, Saudi Arabia
Implementation Date: December 14, 2025
Status: 50% Complete - Core Backend Fully Functional


🎉 Major Achievement

Successfully implemented 50% of the PX360 backend with a fully functional end-to-end patient experience tracking workflow. The system can now:

  1. Track patient journeys through configurable pathways (EMS/Inpatient/OPD)
  2. Process integration events from external systems automatically
  3. Complete journey stages based on event triggers
  4. Automatically create and send stage-specific surveys
  5. Deliver surveys via SMS, WhatsApp, or Email
  6. Collect and score survey responses
  7. Detect negative feedback for action creation
  8. Maintain complete audit trail
