AI in the NHS: rewards, risks, and reality The NHS must avoid AI's seductive overdiagnosis trap, writes Professor Christina Pagel, director of UCL’s clinical operational research unit

AI could be hugely beneficial to the NHS, but only if it augments, not replaces, human judgement, and is deployed with strong governance and equity-aware data.

Plus of course the challenges of workforce and infrastructure remain!

A new piece by me.

Really enjoying #HACA2025! It brings the #publichealth & #socialcare community together and surfaces all the brilliant work happening quietly in the background. 💙

Bonus of an online conf: lunchtime sea swim 🌊

A festive digital illustration features the blue R logo wearing a red Santa hat with white trim on the left. To its right stands a green Christmas tree made entirely of curly braces arranged in a triangular shape. White and light-blue %>% pipe symbols float across a dark blue, starry background like snowflakes. A speech bubble above the R logo says “Ho Ho Ho! 📦” in red text. At the bottom, white text reads: “R Package Development Advent Calendar 2025” and below it, “25 Days of Coding Magic • Dec 1–25.”

7 Efficient optimisation | Efficient R programming Efficient R Programming is about increasing the amount of work you can do with R in a given amount of time. It’s about both computational and programmer efficiency.

+1 for Paul's comment. I used to teach Efficient R and the best speed-ups people found were often from

- Using more compute
- Profiling to identify bottlenecks

This book is a bit out of date but has good concepts: csgillespie.github.io/efficientR/p...

One of the things that has been on my to do list for a very long time, is building a gallery of all of the charts I've made across #TidyTuesday, #30DayChartChallenge, #30DayMapChallenge, and other miscellaneous projects 📊

Back from @nhsrcommunity.bsky.social
conference with a very full brain + heart 💙🤓🐍

So good to swap ideas with people who care about #opendata, #reproducibility, and quality code.

Very grateful for this community 💙

Free #RAP support for #NHS staff. Tomorrow at 10am. Come join the chat 🗨️

Links to register in the thread 🧵

It was great to see so many NHS data professionals at @nhsrcommunity.bsky.social 2025! There was lots of fantastic discussion about #RAP (Reproducible Analytical Pipelines) and our next #NHS RAP drop-in is this Wednesday 19th November 2025 from 10-11 AM.

I've been waiting for this recording to go up because I've heard _so many people_ say how useful it was. And I too am a very frustrated {renv} user. Thanks @pipinghotdata.com 🙏

If you've ever fought with {renv}, you *have* to go watch Shannon's talk from posit::conf. I had soooo many 💡 moments the first time I saw it!
