Clinical Safety Officer requirements
The practical requirements for a CSO under NHS digital clinical safety work: professional registration, clinical risk management training, authority, evidence access and real accountability for the safety case.
Short answer
A CSO must be more than a name on the file.
A Clinical Safety Officer should be a senior registered clinician with current professional registration, sufficient training in digital clinical safety and clinical risk management, and enough authority to challenge product and release decisions. The role is accountable clinical judgement, not administrative sign-off.
For supplier-side DCB 0129 work, the CSO needs enough access to the product, intended use, users, workflow, hazards, controls, testing evidence, known limitations and release boundary to decide whether residual clinical risk is acceptable.
Checklist
What to check before appointing a CSO.
Registration
Current clinical registration
Check current professional registration with an appropriate regulator for the clinician's profession, such as the GMC for doctors or NMC for nurses and midwives.
Training
Clinical risk management training
Check training in digital clinical safety and clinical risk management, including familiarity with DCB 0129, DCB 0160, hazard logs and clinical safety case reports.
Authority
Ability to challenge release
The CSO must be able to challenge weak controls, unsafe assumptions and missing evidence, including delaying sign-off if residual clinical risk is not acceptable.
Access
Product and workflow evidence
The CSO needs enough detail on intended use, users, patient group, care setting, integrations, release scope and operational dependencies to make a defensible decision.
Domain fit
Relevant clinical judgement
Clinical safety depends on real workflow. A CSO should understand the clinical setting well enough to spot plausible harm routes and weak mitigations.
Lifecycle
Post-go-live governance
Material product changes, new settings, incidents and emerging hazards can require safety impact review, hazard log updates and renewed clinical safety assessment.
External CSO
When an external CSO can work.
An external or independent CSO can be appropriate for supplier-side DCB 0129 work where the supplier does not employ a suitable clinician. The engagement still has to give the CSO real visibility and authority: product access, evidence access, hazard workshop involvement, clinical context and the ability to refuse or qualify sign-off.
What does not work is a rubber-stamp signature after the safety case has already been written. If the CSO cannot inspect the evidence, challenge controls or understand how the product affects care, the sign-off is weak for DTAC, procurement and future incident review.
Dr Chiho Song is an NHS doctor in England and a contracted Clinical Safety Officer. For suitable supplier-side scopes, he can support DCB 0129 clinical safety cases, independent CSO review, named CSO retainer work and post-go-live change review.
Evidence
What the CSO usually reviews or approves.
The requirement is practical: the CSO needs linked evidence, not a title in a policy document.
CSCR
Clinical Safety Case Report
The structured argument that the defined system is safe for release in its intended context.
