HealthcareIndustry: HealthcareEvent-Driven Reactive Clinic Flow & WebSocket Queue Architecture

Outpatient Queue Management & Doctor Consultation Station

A smart digital OPD token system and physician consultation station eliminating hospital waiting room congestion and streamlining clinical prescriptions.

Operational Challenge

The Business Challenge

A 200-bed hospital experienced severe waiting room congestion, delayed doctor rounds, and frequent patient complaints due to chaotic manual token management.

Engineering Approach

Our Engineering Solution

We developed an integrated OPD workflow system: self-service check-in kiosks, digital waiting room queue displays, a fast physician prescription pad with drug interaction warnings, and automated pharmacy notifications.

System Architecture & Design

Technical Architecture Breakdown

Real-time hospital consultation orchestration system routing patients from self-service check-in kiosks to physician consultation desks and pharmacy counters.
