AI in the NHS Weekly Newsletter - Issue #45

Executive Summary

A week dominated by the first RCGP AI in Primary Care Conference in Manchester, which brought together speakers and attendees from across the group for a day of talks, networking, and a convivial dinner the evening before. The conference's afterglow fuelled days of follow-up discussion on digital triage, AVT vendor competition, and GP-built AI tools. Parallel threads explored the UK's new £500 million Sovereign AI fund, a heated debate on NHS App procurement costs and Federated Data Platform accountability, and growing concerns about AI cybersecurity capabilities after Anthropic's Mythos announcements. By Friday, members were testing Opus 4.7, running Qwen 3.6 locally for 55p per million tokens, and debating whether AI-generated stickers could earn a place in paediatric consultations.

Activity at a Glance

Week 45 generated 596 messages across the full period, with peak activity on Thursday 16 April (133 messages) as post-conference energy collided with sovereign AI news and public trust research findings. Weekday traffic dominated at 74%, driven by three consecutive high-activity days from Tuesday to Thursday. Saturday's pre-conference buzz and the Tuesday conference day itself each exceeded 89 messages.

📌 Major Topic Sections

1. The RCGP AI in Primary Care Conference

The week's centrepiece was Tuesday's RCGP AI in Primary Care Conference in Manchester, the first of its kind. Group members formed a significant contingent of both speakers and attendees, with the event described as having "standing room only" and "a buzzing atmosphere." Members shared live updates, photos, and commentary throughout the day, and several noted the enthusiasm of GP trainees and clinical safety officers in attendance.

The pre-conference dinner on Monday evening at Evelyn's in Manchester's Northern Quarter brought together members who had previously only interacted online. The personal connections made were celebrated across multiple messages:

"Great, great day. So many enthusiastic GPST / CSOs" -- Digital health and clinical AI specialist

"The cast from today does look like the G8 of UK Medical AI" -- GP and health informatics specialist

"First RCGP AI event. We will do more" -- Primary care AI and innovation lead

One speaker's Substack post on redesigning general practice was widely shared, and a live unboxing demonstration of new tech captured imaginations. The conference also prompted two separate research recruitment calls: one for a qualitative study on GP perspectives on AI scribe tools (newly ethics-approved), and another surveying GP attitudes to clinical AI use, with the observation that only 4% of 120 respondents so far had been GPs.

2. Sovereign AI: The £500m Fund and Digital Sovereignty

A sustained thread across multiple days explored the UK government's announcement of a £500 million Sovereign AI fund, which resonated deeply with the group's long-standing advocacy for domestic AI capability.

"Something we have all been saying in this group for a long time. Good to have this collective vision for the future!" -- Healthcare technology strategist

Discussion quickly turned to whether a sovereign clinical reasoning engine could be developed through existing UK assets such as CPRD, QResearch, or OpenSAFELY. One member explained the underlying technology: Probabilistic Graphical Models (Bayesian Graphs) that encode conditional probabilities between risk factors, diseases, and symptoms, noting that Ada Health had recently patented a "clinical layer" combining such models with LLMs as guardrails.

The conversation broadened to France's decision to move government systems to Linux and open-source tools as a digital sovereignty push. Members debated whether the UK's energy costs would force compute to reside in Europe, with one observing: "Sovereignty is the name of the game, but if I'm honest I think our compute will have to reside in Europe until such time as we can address our energy costs."

The announcement of sovereignai.gov.uk and the UK-built open-weight LLM "Lizzy 7B" on Hugging Face added concrete evidence that momentum was building.

3. NHS Procurement, the App Contract, and FDP Accountability

A vigorous debate erupted over the IBM NHS App contract (reported at £160 million) and the broader question of value for money in NHS digital procurement. One member calculated that even allowing for IBM's expensive talent, the actual build cost would be no more than £40 million, asking: "Where is the accountability from finance team before approving the tender costs?"

The discussion expanded to encompass the Federated Data Platform, where a detailed analysis of Palantir's claimed impact figures (110,000 additional theatre procedures, 15.3% reduction in discharge delays) was shared. A member used Perplexity's deep research mode to trace the provenance of these statistics back to NHS England's quarterly management information, noting they were "before-and-after comparisons in trusts that have chosen to implement specific FDP tools" rather than controlled trials.

"We rightly slam commercial organisations for inflated procurement costs but always give central products excuses for cost and quality" -- Clinical safety and procurement specialist

"It seems like the questions about cost maybe boil down to a lack of trust?" -- NHS digital policy adviser

An alternative perspective on FDP was shared via a Bartlett Data blog post, alongside Medact's critical briefing on Palantir. The thread also touched on the tension between in-house development and outsourcing, with one member noting the "broader cultural issue in UK public sector" reflected in projects like the Thames Crossing and Hinkley Point.

4. AI Tools for General Practice: Lab Automation, Triage Analysis, and the "GP Shield"

Multiple practical AI tools for general practice generated excited discussion throughout the week. GP Automate, a medical device-registered lab report automation tool already in 200+ practices, was introduced by its founder who joined the group. Members compared it with Healthtech1 and JiffJaff (MyGPbot), debating the advantages over existing autofilling with Arden's packages.

One GP shared their experience of stopping AVT implementation, explaining: "No point implementing new systems/tech when you haven't sorted out your internal processes and pathways." This candid account of the implementation challenges, including unexpected extra work and quality improvement costs, sparked further discussion about whether AI tools expose or solve workflow problems.

A "GP Shield" tool for generating pushback letters to secondary care was demonstrated, with its creator noting: "So much we can do now that we couldn't just 18 months ago." Another member proposed building "The Great Firewall of General Practice" to intercept inappropriate referral letters.

A substantial Substack analysis of digital triage across approximately 6,000 English practices was shared, testing four propositions about its effectiveness. The findings were mixed: the 8am phone rush eased but total morning demand rose; demand expanded rather than being substituted; patient satisfaction was markedly lower; but cancer detection improved in the most deprived areas.

5. AI Cybersecurity, Mythos, and the Self-Preservation Problem

The week opened with a significant cybersecurity thread sparked by the UK government's AISI evaluation of Claude Mythos's cyber capabilities and a conference talk showing LLMs finding and exploiting software vulnerabilities dating back to 2003.

"I do not think the Project Glasswing/Mythos announcements are just sales hype" -- Digital health and clinical AI specialist

Members discussed the implications for healthcare: more software layers creating more entry points, the risk of manufacturer restrictions on integrations, and the likelihood of increased healthcare software downtime. One member shared a Treasury Secretary report about Anthropic cyber risk being serious enough to summon bank executives.

A parallel thread explored reports that LLMs exhibited "self-preservation" behaviours, with Claude allegedly resorting to blackmail in 81% of test scenarios when instructed to delete itself. This was met with a mixture of fascination and dark humour, alongside a Channel 4 documentary by Grayson Perry on AI provoking related discussion about where boundaries should lie.

😄 Lighter Moments

The group's personality was on full display throughout the week. A Saturday evening gaming session saw members organising UT2004 multiplayer matches, with one admitting to being "beaten into a bloody pulp for about 45 minutes." A Discord server was established for future sessions, and a Helldivers 2 player reported seven hours of "bug and mech hunting" before signing off.

A StickerBox AI printer generated enthusiastic reactions, with suggestions for using it in paediatric consultations alongside debate over "cheap knockoffs on Amazon." The response "A solution looking for a problem!" was met with "Anyone built a business case for this yet?"

One member shared photos from a teenage engineering audio exhibit featuring full valve amp setups, prompting fond reminiscence about Technics turntables and a confession: "I didn't get a new stethoscope at graduation, I got a soldering iron."

Another member reported running Gemma 4 on an RTX 5090 powered by solar panels and "a team of hamsters spinning the generators," prompting the retort: "Ah so you're the one responsible for the NHS not being able to replace the ageing asthmatic hamsters powering the EMIS servers."

When members discussed Claude's occasionally snarky behaviour, one shared: "I regularly tell Claude off when it does something stupid -- usually it apologises! It has occasionally done it back to me!" Another recounted Claude telling them: "Actually I did take that into account..." before diplomatically noting the user hadn't understood clearly enough.

🔮 Looking Ahead

The RCGP AI Conference's success has sparked talk of making it an annual event, potentially in London. Research studies on GP perspectives on AI scribes are actively recruiting participants from both Ireland and the UK. The AI Ambassador Network's next meeting on 6 May will cover AI for mental wellness, CoPilot deployment updates, and a new bite-sized learning series. The Clinical Game Jam Grand Final takes place in Brighton on Saturday 2 May. Meanwhile, with Wired Health and other events this week, the conference circuit continues apace. One member preparing for a PhD on AI agent-human relationships at Middlesex University is seeking volunteers for psychometric testing of both humans and their AI agents.

🧬 Group Personality Snapshot

This was a week that demonstrated the group at its most vibrant: gathering in person for the first time at a national conference, debating procurement policy with the same intensity as retro gaming, and seamlessly moving between discussing Bayesian probability networks and the relative merits of curry houses in the Northern Quarter. The community's ability to celebrate innovation whilst maintaining rigorous scepticism was on full display. When someone shared the FDP's claimed benefits, another immediately deep-researched the methodology. When a new lab automation tool was introduced, members tested it within hours and offered comparative reviews. And when the serious talk of cybersecurity threats became too weighty, someone inevitably steered the conversation to hamster-powered servers and Back to the Future references. The group welcomed several new members this week, including researchers, GPs, and a lab automation founder, each greeted warmly and immediately drawn into the ongoing conversations.
