Predixia Cabinet

Medical practice software

You don’t run a paediatric practice the way you run a gynaecology practice.

Other software lets you “customise a few fields”. Here the whole record follows your specialty: the sections of the report, the measurements you track, the length of your appointments — and what the software demands before it will let you prescribe.

No commitment — we open a trial practice configured for your specialty.

Record
Consultation 20 min

A practice workstation: laptop and stethoscope.

The record is what the doctor reads again. Everything else is plumbing.

And what you read again depends on the specialty: a dermatology report does not have the same headings as an ophthalmology report.

The software

One record, from the first appointment to the last prescription

These nineteen screens are not mock-ups: they are photographed from the running software. The first nine come from the same record — Sofiane, thirteen, followed for nine months for nodular acne. The same story reads in the growth chart, in the lab results, on the images and on the invoice.

The record — five signed consultations, from November to August.
The record Five signed consultations, from November to August. A signed consultation can no longer be altered: it is completed by a dated addendum.
The medical summary — the allergy is recorded with the code of its substance, not its brand name.
The medical summary The allergy is recorded with the CODE of its substance, not its brand name. That is what will later allow a prescription containing it to be refused.
The charts — weight, height and two dermatology scores.
The charts Weight, height, and two dermatology scores. Acne severity falls from 5 to 1, the reported burden from 21 to 3 — nine months at a glance.
Imaging — a scheduled examination appears in the device’s worklist.
Imaging A scheduled examination appears in the device’s worklist: the operator picks the patient there instead of retyping them, and the record number comes back intact in every image.
Lab results — two HPRIM laboratory reports, read automatically.
Lab results Two HPRIM laboratory reports, read automatically. Out-of-range values are the only red in the entire interface.
The prescription — written on the official medicines reference, checked before signing.
The prescription Written on the official medicines reference, checked before signing — and overriding a check means writing down why.
The care claim — procedures at the practice’s rates, the care pathway, direct billing.
The care claim Procedures at the practice’s rates, the care pathway, direct billing. An issued document is never deleted: it is cancelled, and the cancellation produces a credit note.
Documents — letters, certificates and invoices, produced as PDFs on the practice letterhead.
Documents Letters, certificates and invoices, produced as PDFs on the practice letterhead and filed in the record.
Incoming documents — signed consent forms, reports, certificates, insurance cards.
Incoming documents What arrives from outside: signed consent forms, reports, certificates, insurance cards.
The diary — the practice’s week, one colour per practitioner.
The diary The practice’s week, one colour per practitioner. An appointment placed outside opening hours is accepted, but it says so.
Revenue — the register, unpaid items, and each doctor’s share.
Revenue The register, unpaid items, and each doctor’s share — what a group practice looks at at the end of the month.
What the figures don’t know — activity, patient base, prescribing.
What the figures don’t know Activity, patient base, prescribing. And, at the top, what the software cannot measure: it says so rather than letting you believe otherwise.
On the phone — the day: the next patient, the waiting room and its real waiting time.
On the phone — the day The next patient, the waiting room and its real waiting time — counted from arrival, not from the appointment time. No patient data is stored on the device.
On the phone — the diary: no week grid, a load figure under each day.
On the phone — the diary No week grid: shrunk to the width of a phone, you can no longer read a name on it. The figure under each day gives its load, and you see where room is left without going in.
On the phone — the medical summary: allergies, long-term treatments, history and vaccinations.
On the phone — the medical summary Allergies, long-term treatments, history and vaccinations, with their batch numbers. Closing does not delete: the record keeps the entry and its end date.
On the phone — the charts: an adolescent’s weight and height over nine months.
On the phone — the charts An adolescent’s weight and height over nine months, and the two dermatology scores falling under treatment. These are the same coded measurements as on the desktop, not a second entry.
On the phone — the images: the image goes to the practice’s image server, never to the camera roll.
On the phone — the images The image goes to the practice’s image server, never to the camera roll. You review it here; the screen itself says it is to be interpreted on the desktop.
On the phone — recording an allergy: it is recorded with the code of its substance.
On the phone — recording an allergy This is the feature that justifies the app on its own. An allergy is discovered at the patient’s side: it is recorded there, with the CODE of its substance, and from the very next prescription it refuses any medicine containing it.
On the phone — revenue: the register, unpaid items, and each doctor’s share.
On the phone — revenue The register, unpaid items, and each doctor’s share. A group practice looks at this screen at the end of the month — it does not have to come back in for that.

What the specialty changes

Four things, and they fit in one file

Adding cardiology does not call for a new version of the software. It calls for writing down what a cardiologist does.

Measurements, not fields

A blood pressure written into a paragraph is lost for good. Here it carries a code, a unit and, where relevant, a side — ophthalmology measures everything twice. Three years later, it is still on a chart.

The real length of an appointment

A fundus examination requires dilation: the next slot cannot be placed right after it. An excision occupies the room for forty minutes. The diary knows this without being told each time.

What the specialty demands

In paediatrics, a dose is calculated in milligrams per kilogram. Until the child has been weighed that same day, the software refuses the prescription. The weight from the last visit is not enough.

What is still there ten years on

A coded measurement becomes a chart

A weight written into a paragraph is lost for good. The same weight, coded with its unit, appears on a chart and is compared against the World Health Organization reference.

The lesion is located, not described

“A pigmented lesion on the upper back, on the left” cannot be found again three years later. A dot on a body diagram can — and the measurement of its largest diameter compares from one visit to the next.

Back, left scapular region · 7 mm · asymmetry, irregular borders

Imaging

A real image server, not a photo gallery

Your devices speak DICOM. So does the practice — and it publishes the worklist they query before every acquisition.

D000042 NGUYÊN^Thi Mai XC · Dermoscopy of the back 3 / 12
10 mm
01

You schedule the examination

From the record: type of examination, title. The practice enters the patient into the worklist, with their record number.

02

The device queries the practice

The operator picks the patient from a list instead of retyping them. That is where it is all decided: retyped, “Nguyên Thi Mai” comes back as NGUYEN^THIMAI, and somebody attaches the images by hand — sometimes to the wrong record.

03

The images come back already filed

The record number comes back intact in every image. A photograph taken at the practice becomes a DICOM image just as much as a device acquisition, and lives in the record — not beside it.

Prescribing

Three checks that almost nobody makes

They are computed on the composition of the medicines, which the public database gives away free. No surcharge, no subscription.

01

The known allergy

Recorded from the medicine itself, and therefore coded — not written out in words, where it compares to nothing. Prescribing a medicine containing that substance is refused.

02

The same active substance twice

The most ordinary overdose there is: nobody thinks that the paracetamol tablet and the flu remedy both contain paracetamol. Two lines, one molecule: refused.

03

The substance already being taken

It already appears in a current long-term treatment. Flagged, without blocking — because sometimes it is intended.

A check that can never be overridden ends up being worked around some other way — by retyping the medicine as free text — and the record then keeps no trace of the decision. Here you override by giving your reason, and the reason stays.

The medicines database

Free, official, up to date

The French public medicines database — ANSM, HAS and the national health insurance fund. Reloaded every month, searchable by brand name or by international non-proprietary name, forgiving of typing mistakes.

Lab results

The results arrive, the software proposes, you confirm

The laboratory report arrives in HPRIM format. It is read, its values are unfolded, anomalies flagged — and the original file is kept exactly as it came, because that is the one that counts.

Matching to a patient is never automatic. A test result filed in the wrong record is only discovered the day it drives a decision. The software proposes candidates and says why; a human decides.

A microscope in a medical analysis laboratory.
An empty medical practice waiting room.

The waiting room knows how long each person has been waiting.

Counted from the patient’s arrival, not from the appointment time: a patient who came twenty minutes early has not been waiting on twenty minutes of practice delay.

Today

What works, and has been verified

380 end-to-end checks, replayed at every release.

Diary and waiting room

Opening hours, absences, free slots. Two appointments cannot overlap: the rule is laid down by the database, not only by the screen. Two simultaneous clicks do not get through.

Patient record

History, coded allergies, long-term treatments, vaccinations, charts. A duplicate record is refused even when written without accents or capitals.

Consultation and prescription

The report follows your specialty. The prescription is signed and printed in a single gesture, in international non-proprietary names.

Sealed documents

Prescriptions, certificates, letters, reports, invoices. Each is archived with its fingerprint: it proves it has not changed since it was handed over.

Revenue and accounting

Daily takings, quotations, bank deposits, accounting export. Numbering is continuous and without gaps, and an issued invoice is cancelled by a credit note — never by a deletion.

Equipment and fixed assets

Schedule of inspections, medical device vigilance, fixed asset register. A failed regulatory inspection does not push back the due date and puts the device out of service.

Laboratory results

HPRIM import of laboratory reports. The software proposes a patient, a human confirms — a result filed in the wrong record is only discovered too late.

Documents in the record

Incoming letters, consent forms, colleagues’ reports. A document is not erased: it is withdrawn, with its reason.

Your data stays yours

One practice, one database schema. A colleague from another practice cannot read your records, even knowing a patient’s identifier.
