The challenge

Brief · 01

In 2024 alone, Raipur district reported 1,894 road accidents and 524 fatalities — many of them avoidable if the patient had reached the right hospital within the golden hour. Ambulances often hopped between hospitals searching for capacity, hospitals were unprepared on arrival, referrals happened over phone calls with no audit trail, and the CMO had no live visibility into pre-hospital care. The system needed to coordinate seven distinct stakeholders, work over poor connectivity, and remain usable by an EMS nurse in under 30 seconds while a patient is being transported.

The solution

Brief · 02

We built Golden Hour as a three-surface platform — a Flutter mobile app for EMS staff, hospital incharges and doctors; a React + FastAPI admin console for the CMO; and a notification spine that fans out via push, SMS and SOS messaging. Patient details captured at the accident site auto-submit in 30 seconds, the system recommends a priority-ranked hospital list using live capacity data, the chosen hospital's head doctor either assigns or refers the case, and the receiving doctor gets ambulance tracking and ETA before the vehicle arrives. Handover is locked behind a one-time QR / OTP, so the case can only close when the doctor physically takes charge. Every action is logged for the CMO's live monitoring dashboard.

Milestones

From early concepts through validation and iteration.

  1. Studied Raipur district trauma data with the CMO and mapped every actor in the chain

    caller, ambulance, EMS staff, hospital incharge, assigned doctor, admin.

  2. Designed the 30

    second nurse form with a clickable body — injury diagram, condition triage and recommended hospital priority list.

  3. Built the FastAPI backend with role

    aware routing, real — time hospital capacity, and a notification fan — out across push, SMS and in — app SOS channels.

  4. Shipped the Flutter app with separate flows for EMS, hospital incharge and doctor

    including ambulance tracking, refer — to — doctor, and QR/OTP handover.

  5. Delivered the React admin console for the CMO with live episode monitoring, hospital readiness, doctor

    assignment audit, and district — level analytics.

  6. Ran handover dry

    runs with hospital staff and iterated on referral notes, SMS templates and the offline — tolerant sync model.

03 / Outcomes

  • Reduced ambulance-to-hospital handover from multiple phone calls to a single 30-second digital form.
  • Eliminated hospital-hopping by routing every ambulance to a confirmed-capacity destination.
  • Established a tamper-proof audit trail of who treated whom, when, and why a referral was made.
  • Gave the CMO live district-wide visibility into every active emergency episode.
  • Created a scalable template that other districts can adopt to operationalise the golden-hour protocol.
