Hospital Management System
Registration to diagnosis to an SMS report link.
The problem
A hospital running medical check-ups on paper: patients queued at every desk, results were typed twice, and reports were collected in person days later. The system had to follow the real physical flow of a patient through the building — not an idealised one.
A full clinical workflow — from patient registration to lab results and auto-generated reports delivered by SMS — used daily by a hospital.
What I built
Patient journey
Registration, money receipt, sample collection and test assignment as one connected flow, each step visible to the next desk.
Pathology, radiology & physical tests
Dedicated entry modules where doctors record observations against the exact sample and test that was ordered.
Automatic fit / unfit verdict
Rules over the entered results decide the verdict and surface which parameters caused it, instead of leaving it to manual reading.
X-ray annotation
Radiologists draw directly on the image to mark the problem area; the annotation is stored with the report.
Report delivery by SMS
The final report is generated automatically and the patient receives an SMS with a link — no return trip to the hospital.
Biometric & passport capture
Fingerprint identification for returning patients and a WebSocket-driven passport scanner that auto-fills registration forms.
Hard parts
- 01
Hardware that lives outside the browser
Passport scanners and biometric devices talk to a local machine, not a web page. I bridged them over WebSocket so the browser could receive scans instantly while keeping the desk workflow uninterrupted.
- 02
Annotating medical images accurately
Drawing on an X-ray has to survive zoom, different image sizes and re-opening the report. I stored annotations as coordinates relative to the image rather than baked-in pixels.
- 03
Stability under daily load
The platform served thousands of users a day. I refactored the diagnosis flow for correctness and stability, since a wrong or missing result is a clinical problem, not just a bug.
My contribution
- Patient registration, money receipt, and sample collection flow, wired end-to-end.
- Pathology, radiology, and physical test modules where doctors enter observations from collected samples.
- Auto-generated fit / unfit verdicts and issue detection based on doctor-entered results.
- X-ray annotation tool letting radiologists draw the problem area directly on the image.
- Auto-generated patient-facing reports with an SMS delivering a secure report link to the patient.
- Biometric patient identification and a WebSocket-based passport scanner for instant form auto-fill.
Outcome
- Patients receive reports by SMS link instead of returning to collect them.
- Verdicts and issue detection generated automatically from entered results.
- Registration time cut by scanner and biometric auto-fill.
