Dr Chiho Song is a practising NHS doctor and a contracted Clinical Safety Officer (CSO) in England. He prepares, reviews and signs off the DCB 0129 and DCB 0160 clinical safety cases that digital health products need before they can go live in the NHS — fixed scope, fixed fee, four-week turnaround.
Dr Chiho Song (also written Chi Ho Song) is an NHS oral & maxillofacial surgery clinician and a contracted Clinical Safety Officer based in England. He acts as the named CSO for digital health and SaMD teams, preparing DCB 0129 and DCB 0160 clinical safety cases and signing the go-live release memo that lets a product be used safely in the NHS.
A Clinical Safety Officer owns the clinical risk of a health IT system end to end — from hazard identification through to a signed statement that residual risk is acceptable.
Runs the hazard workshop, builds the hazard log and clinical risk management file, and scores risk before and after mitigation.
Writes the DCB 0129 clinical safety case report and safety requirements specification that auditors, DTAC and NHS trusts expect to see.
Reviews residual risk and signs the CSO release memo — the accountable statement that the system is safe to deploy.
A clinical safety case is an accountable clinical judgement, not a paperwork exercise. The value of a Clinical Safety Officer is that a registered clinician — one who understands the real workflows your SaMD has to be safe inside — is willing to put their name to the statement that residual risk is acceptable.
Dr Chiho Song is a practising NHS doctor as well as a contracted CSO, so hazards are identified from the clinic floor, not from a checklist. That is what makes a DCB 0129 clinical safety case credible to a trust's clinical safety committee, to DTAC reviewers, and to a regulator looking at it later.
A defined fixed-fee package gets you from kickoff to a signed go-live release memo; ongoing work after go-live is scoped separately. See full pricing and scope →
Hazard workshop, clinical risk management file and hazard log, DCB 0129 clinical safety case report, safety requirements specification, written post-market surveillance plan, and the signed CSO go-live release memo — handed over audit-ready in four weeks.
Running post-market surveillance, safety and incident reviews, hazard log updates, sign-off of major product changes or new hazards, DTAC and DSPT cross-walks, and recurring governance are scoped separately so the fixed fee stays fixed.
A suitably qualified clinician, trained in clinical risk management, who is accountable for the clinical safety of a health IT system. DCB 0129 and DCB 0160 require a named CSO to review and approve the clinical safety case before a system is used in patient care.
The NHS standard for clinical risk management in the manufacture of health IT systems. It requires manufacturers to run a clinical risk management system and produce a hazard log, clinical risk management file and clinical safety case report, signed off by a CSO.
The companion standard for organisations that deploy and use health IT — NHS trusts and care providers. It requires the deploying organisation to manage clinical risk through its own CSO when it configures, deploys and uses a system.
Whenever a health IT system or SaMD is used by or within the NHS. In practice you need a named CSO and a DCB 0129 safety case before you can pass DTAC, complete procurement, or go live in a trust.
