“Safety is not the absence of risk; it is the presence of controls.” Nancy Leveson

As AI accelerates across healthcare, one question is becoming increasingly important:

Who is ensuring these systems are clinically safe — before they reach patients?

We talk about innovation. We talk about efficiency. We talk about adoption.

But safety — real, structured, defensible safety often receives less attention than it should.

This is where the role of the Clinical Safety Officer (CSO) becomes critical.

What a CSO really does (beyond the title)

The CSO role is often misunderstood as a sign-off function

It is not.

A Clinical Safety Officer ensures that digital systems:

  • are safe by design
  • have identified hazards and risks
  • include mitigation strategies
  • are tested in real clinical contexts
  • remain safe after deployment

It is a continuous responsibility, not a one time approval.

Why AI makes the CSO role more important than ever

Traditional systems behave predictably. AI systems can behave problematically.>

That introduces:

  • uncertainty in outputs
  • variability across populations
  • dependency on data quality
  • evolving performance over time

Which means safety cannot be assumed.

It must be actively managed.

From compliance to clinical safety leadership

Too often, organisations approach standards like:

  • DCB0129 (manufacturers)
  • DCB0160 (deployers)

as tick-box exercises.

But true clinical safety requires:

  • embedding safety thinking into design
  • continuous monitoring and review
  • clear escalation pathways
  • defined accountability
  • clinician engagement

Compliance documents do not create safety. Leadership and culture do.

Where many organisations struggle

In practice, common gaps include:

  • CSOs brought in too late (post-design)
  • unclear accountability between digital, clinical, and operational teams
  • safety cases written but not operationalised
  • lack of continuous monitoring after go-live

When this happens, governance becomes theoretical.

And risk becomes real.

The CSO as a bridge

A strong CSO acts as a bridge between:

  • clinicians
  • developers
  • digital teams
  • executives

Translating:

  • clinical risk into technical requirements
  • technical limitations into clinical understanding
  • governance standards into real-world practice

It is not just a safety role. It is a translation and leadership role.

A personal reflection

In my own journey working across urgent care, governance, and digital transformation, one thing has become clear:

The success of any digital system is not defined at deployment. It is defined by how safely it performs over time.

And that safety does not happen by chance. It is designed, led, and continuously reviewed.

Reflection Question

In your organisation, is clinical safety embedded from the start or introduced after the system is already live?

Because in the age of AI, innovation without clinical safety is not progress.
