Most health systems deploying clinical AI
believe they have governance covered.
Data teams managing inputs.
Legal and risk reviewing the model.
Operations integrating the workflow.
A charter signed at the board level.
On paper it looks complete.
One circle is missing.
It is the only one that matters
when something goes wrong at the bedside.
This issue walks through each circle.
What your institution already has.
What it is still missing.
And exactly what the activation requires.
The first circle is Data Governance.
Every serious health system
has built this one.
The data stewards, the architects,
the security teams.
They exist to protect the inputs
that shape everything downstream.
Without trustworthy data inputs,
nothing that follows can be trusted.
This circle is solid in most institutions.
It took years to build.
Most organizations know it well.
Circle 1 is solid. The foundation holds.
The second circle is AI Governance.
Legal, risk, ethics, product.
The teams that review the model
before it touches anything clinical.
This circle is drafted in most institutions.
Not always complete.
Not always clinical.
But present.
It covers the general outputs
the model produces.
What it cannot do is follow
the recommendation to the bedside.
Circle 2 is solid. The model is reviewed.
The third circle is Healthcare AI Governance.
Operational leadership, compliance, quality.
The layer that integrates AI into
the workflow and makes sure the deployment
does not break anything on the way in.
This circle is closer to the patient
than the first two.
It governs the operational decisions
that surround the clinical encounter.
It stops at the door of the room
where the clinician and patient are.
Circle 3 is solid. The workflow is governed.
And then there is the fourth circle.
Clinical AI Governance.
The circle that covers the moment
the AI recommendation crosses the threshold
from system output to clinical decision.
The moment a clinician looks at
what the model produced
and makes a call that affects
a human being in front of them.
Look at the figure.
Two empty chairs inside a dotted circle.
The chairs are there.
The seats exist.
No one has been named to sit in them.
The left chair is the Governance Owner seat.
The person who approved this AI
for use in this clinical context.
Who holds the ongoing authority
to run it or pull it.
Who answers when the system
produces a harmful output.
Who charters the deployment,
commissions the role,
and covers the institution
when accountability is demanded.
The right chair is the Decision Owner seat.
The person who received the AI
recommendation and made the consequential
clinical judgment.
Who documented what the AI recommended
and what they decided and why.
Who stands behind that decision
when someone asks.
Both chairs are empty
in most institutions.
The circle is dotted because
no one ever required it to be solid.
The stethoscope above the chairs
is drawn in dashes
because the clinical authority
has not been assigned.
Circle 4 is dotted. The gap is open.
Closing it does not require
a new policy.
It does not require a new committee.
It requires two names.
One for each chair.
When both names are assigned,
something quiet but significant happens.
The dotted circle becomes solid.
And it turns gold.
The fourth circle is no longer dotted.
It is filled.
Gold because the activation has happened.
The two chairs inside it now have names.
The Governance Owner has been assigned.
The Decision Owner has been assigned.
The circle that was missing
is now present.
And when it becomes solid
it meets the other three
at the center of the diagram.
That center point.
The gold circle where all four
circles converge.
That is where the accountability gap
has been sitting open.
Three solid circles and one dotted circle
cannot close that center.
The gap stays exposed.
Four solid circles can.
When the fourth circle activates,
the center fills.
The gold at the convergence point
is not decoration.
It is the signal that the gap
has closed.
Two names. One dotted circle
becomes solid. TAG™ closes.
That is the activation.
That is all it takes.
And in most institutions,
it has not happened yet.
For every clinical AI deployment
currently live in your institution,
one circle is still dotted.
The Governance Owner seat is empty
or the Decision Owner seat is empty
or both.
The activation is simple.
Name the Governance Owner.
Name the Decision Owner.
Both chairs filled.
Fourth circle solid.
The gap closes at the convergence point.

brief under GPe Research Publications.
MedicoVigilance™ is published every two weeks by Mo Johnson, MD MBA, founder of GPe Research. Each issue teaches one piece of the clinical AI accountability discipline your institution needs before the next deployment decision.
Forward this to a colleague whose institution still has a dotted fourth circle.
