The hospital program that runs the same when you leave the building.

EbunOS keeps a small hospital's patients, money, stock and tasks on one laptop in the building. It is built from the hospital's own paper forms, so the record looks the way the staff already work, and a task closes only when the record shows the thing was done.

Built with Ebunlomo Hospital at Idiroko, on the Nigeria–Benin border, from its own forms and on its own floor. The parallel run with paper is starting; EbunOS is not yet in live use anywhere.

What it does

Seven modules on one record, switched on as a hospital needs them

Every module works on its own and with the others. A hospital switches on what it uses; nothing recorded is ever lost when a module is switched off.

The core

Patients, sign-ins and the staff file, payers and the price book, the tasks, the audit log, the backup with a locked copy off site, and the settings — every rule with its source.

Front desk, consultations and billing

Reception and the queue, triage, the consultation note (SF-139), prescriptions, bills, payers and HMO claims with each HMO's own rules, the price book, the daily journal for the accountant.

Pharmacy and stock

Dispensing, walk-in sales, stock and deliveries, orders, the controlled-drug book, the treatment room, and the allergy and dose check on every prescription.

Ward and nursing

Admissions and the bed board, drug orders and the drug chart (SF-118), observations with NEWS2 and timed escalation, fluid balance, notes and handover, consent and refusal, discharge in full.

Laboratory

The test menu with the lab's own ranges and critical limits, requests from the consultation, the ward and walk-ins, results with flags, critical-value calls, quality control, results from the analysers.

Maternity

Antenatal care and the card, the community ANC and its referrals, labour on the partograph (SF-79) with the caesarean decision record, the birth, the newborn, going home, postnatal visits.

Imaging

Ultrasound and X-ray requests, the images kept beside the record (from the machine by DICOM, or uploaded), the reports and corrections, the critical-findings call, the hand-off to a reporting partner.

People

The staff file with an alert before a licence or certificate runs out, the duty rota and its gaps.

Theatre, payroll, quality, governance

The theatre list and the surgical safety checklist come next; payroll, quality and compliance, and governance after that.

How it is built

From the hospital's own forms, with nothing invented

The forms come first

The hospital's forms register, 143 forms from SF-01 to SF-142, is inside the program. Each screen is built from the form the staff already fill, and 35 of the forms print from the record with the hospital's own header and version mark.

Example. The transfusion record (SF-23) asks for two people to check the unit at the bedside; EbunOS asks for the second person's own password before a unit starts.

Every rule shows its source

268 rules, from the lab's critical-value call to the ward's drug-round times, each shown with the form or protocol it comes from. Where the forms give no number, EbunOS proposes one, marks it so, and waits for a doctor to confirm.

Nothing bundled. No prices, HMO tariffs or lab ranges are typed in from memory, and the code lists (ICD-10, ICD-11, LOINC) are loaded from the official files: the hospital prices its own book and confirms its own menu.

A task closes on evidence

When a critical lab value is found, a task is raised for the lab with a 30-minute clock. It does not close when someone ticks it; it closes when the record shows who was told, when, and that they read the value back.

The same for money. A dispensing that is not on a bill, a bill left open after discharge, a claim with a missing HMO code: each is a task for the person whose job it is.

It runs in the building

EbunOS runs on the hospital's own laptop, with or without the internet, and the tablets reach it over the building's Wi-Fi. Every night a locked copy goes off site; a practice copy with pretend patients is there for training; every release updates the records in numbered steps with a backup first.

Tested before every release. 3,435 automated checks, every screen opened as every role, bad input on every form, and independent cold reviews until a round finds nothing serious.

In numbers

As of 9 October 2026, release 2.2.2.

The counts are of the program as built and tested. Hospitals using EbunOS: none yet. The first, Ebunlomo Hospital at Idiroko, is starting its parallel run, in which the staff keep their paper and EbunOS is checked against it every evening before anything is switched over.

Milestones

Where EbunOS has got to

  1. Release 0.9, then 1.0

    The front desk, the pharmacy and stock, bills and HMO claims, the tasks, the practice copy. Grown out of a spreadsheet system built for a four-bed hospital.

  2. The code in a private repository

    With automatic tests on every change, and each release kept as a numbered update that runs on a hospital's existing records.

  3. The ward, the lab, HMO authorisations, maternity

    Releases 1.3 to 1.9: admissions and the drug chart, observations with NEWS2, discharge in full, consent and the incident register, the laboratory, each HMO's rules, antenatal care through to postnatal visits, one patient story and the forms printed from the record.

  4. Settings not programming; the standards; imaging; prescribing; blood

    Releases 2.0 to 2.2.2: every rule a setting with its source, ICD-10 and ICD-11, LOINC, the analyser link, the FHIR record and the NHMIS return, ultrasound and X-ray with the DICOM link, outpatient prescribing and the treatment room, the procedure note, the transfusion record and the drug reaction report.

  5. The name and the company

    ebunos.com and the Nigerian and African web addresses registered; EbunOS Limited's registration begun, with two non-executive directors; the trademark filed in Nigeria.

From the floor

Notes from the parallel run

Nothing to read yet.

When the parallel run at Ebunlomo Hospital begins, the nurse who runs it will write short notes here about what the days are like: what went smoothly, what the staff asked for, what EbunOS got wrong and how it was fixed. The notes are written from the practice copy, with pretend patients; nothing from a patient's record is ever shown.
