Haemoglobin and the neutrophil count have both fallen this week, and both are now below the ward's critical thresholds.

CRITICAL

Hb 6.4 g/dL on 12 Apr, below the ward's critical threshold. Severe anaemia.

Consider · not a finding

A fever during the neutropenic nadir is usually treated as an emergency until cultures are back. Check that against the unit's own protocol before acting on it.

Is this child clear?

Nothing in this record supports that.

Nothing was checked.

No result on file was checked against the ward's threshold rules for this answer. Nothing here has been evaluated and cleared.

The problem

My family's medical history lived in a paper folder.

Every doctor turned it over, then asked us from memory anyway.

Doctors per 10,000 people.

Of 67 countries measured, Bangladesh has the shortest average primary care consultation.

So I built the folder into a phone.

One child's record: condition, labs, medicines, Pulse AI.

Invented patients, no real data.

Then I had to decide what it must never say.

PulseNote / Pulse AI

Pulse AI never writes a number.

Ask a child's record a question. Every statement cites its source.

Hb 6.4 g/dL, 12 Apr, below the critical threshold

The server writes every number.

Worth repeating the count in 2 days.

The model writes the words. A digit gets it rejected.

An answer with nothing flagged still ends: This is not an all clear.

Doses are arithmetic, not generation.

27 tests, 29 curated drug rules, 2 clinicians for a high alert dose. Built and tested, not yet switched on.

One checked door: consent, purpose, audit.

I am not going to publish the architecture.

A record that cannot leave was never the patient's.

5 FHIR R4 resources, 55 tests, HL7 v2 in. No conformance run yet.

The next tool had to know when to say nothing.

ResultNo concern.This childappears well.Removed

Helps frontline doctors catch early signs of cancer in children from a routine blood test.

223 children in the department's leukaemia study. Some confirmed cases arrived with a blood count that looked unremarkable.

The feature I am proudest of is the one I deleted.

It flags a case, or it stays silent. It never reassures.

Where an AI generated document disagreed with the department head's instructions, the instructions won.

It was paper, and nobody on the floor is technical.

I built what they needed, not what I wanted to build.

The role comes from the database, never from the token.

About 158 enforcement points, one verifyRole path. It costs a query. It is worth it.
