NHS AI rollout runs into reality: delays, legacy IT, and lessons for success
AI rollouts in NHS hospitals are tougher than expected, slowed by contracts, legacy IT, and training gaps. Progress needs clear leadership, protected time, and local validation.
Implementing AI in NHS Hospitals Is Harder Than Planned: Lessons You Can Use Now
September 12, 2025
A major UK study led by UCL, published in The Lancet eClinicalMedicine, finds that bringing AI into NHS hospitals is far tougher than expected. The sticking points: governance, contracts, data readiness, integration with ageing IT, tool selection, and workforce training.
The takeaway for healthcare leaders is clear. AI can support diagnostic services, but it won't relieve service pressures without deliberate planning, protected time, and dedicated delivery capacity.
What the NHS AI imaging programme attempted
In 2023, NHS England funded AI tools for chest imaging across 66 trusts, grouped into 12 imaging networks, backed by £21 million. The tools aimed to prioritise urgent cases and support reporting by flagging abnormalities on X-rays and CT scans.
What actually happened
- Contracting ran 4-10 months longer than planned; by June 2025, 23 of 66 trusts were not yet using the tools in clinical practice.
- Clinicians with heavy workloads struggled to engage in selection, governance, and go-live activities.
- Integration into varied, legacy IT stacks across dozens of hospitals slowed progress.
- Staff skepticism and limited familiarity with AI reduced early enthusiasm and adoption.
- Procurement teams were swamped by technical detail, increasing the risk of missing key requirements.
- What helped: strong national leadership, resource-sharing across imaging networks, committed local teams, and dedicated project management.
Why this is hard - and predictable
The NHS is a federation of organisations with different clinical priorities and IT baselines. That introduces variation, governance overhead, and integration effort for every site. Add uncertainty about accountability if AI misses a finding, and the friction is inevitable without targeted support.
Practical steps NHS leaders can take now
- Appoint a dedicated project manager and give them clear authority across radiology, IT, IG, and procurement.
- Protect clinician time for tool selection, validation, workflow design, and governance sign-off.
- Run a standardised procurement pack: clinical requirements, integration checklists (PACS/RIS/VNA), data flows, and success metrics.
- Use a pre-vetted shortlist of suppliers where possible to cut evaluation time and reduce risk.
- Complete DPIAs early; clarify data controller/processor roles and retention. Set audit trails from day one.
- Validate on local data before go-live; define acceptance criteria (sensitivity/specificity, turnaround time impact, false-positive rate).
- Keep a human-in-the-loop: require final clinical oversight and clear escalation routes.
- Specify post-deployment monitoring: drift detection, safety incidents, bias audits, and vendor performance reviews.
- Build a rollback plan and downtime procedures; don't go live without them.
- Share lessons across imaging networks; reuse integration patterns and governance templates.
- Check regulatory status (e.g., UKCA/MHRA for medical devices) and require documented quality management.
Training that works (and addresses real concerns)
- Make education continuous, role-specific, and practical: use local cases and real workflows.
- Cover accountability, error handling, bias, explainability limits, escalation, and medico-legal considerations.
- Train on failure modes and edge cases; simulate incidents and recovery.
- Include IT and clinical safety officers; align with clinical risk management standards.

Procurement pitfalls to avoid
- Overweighting demo performance; underweighting integration and support. Ask for proof of stable performance on comparable NHS sites.
- Undefined success metrics. Tie payments or renewal to measurable outcomes.
- Loose data terms. Lock down data use, model retraining rights, deletion, and secondary use.
- No plan for upgrades. Agree versioning, re-validation triggers, and change control.
- Ignoring cybersecurity. Require minimum standards and penetration testing evidence.
What to expect next
The evaluation focused on procurement and early deployment. The research teams are now studying use after embedding, and adding patient and carer perspectives to address equity and experience. Expect more clarity on where AI adds value in routine reporting and where it doesn't.
Bottom line: AI can help, but only with disciplined delivery, local validation, and continuous training. Plan for the work, not the headline.
