New OpenSAFELY paper 👇

🚨 OpenSAFELY Milestone Paper! How did the pandemic affect diagnosis rates for chronic diseases? We analysed rates for 19 long-term conditions in 30m people in England. The results are out this week in @bmj.com 📄 Read here: doi.org/10.1136/bmj-...

Live from Oxford with Professor Ben Goldacre — Bad Pharma, Good Data, Better Care We take the stage at the @bennettoxford.bsky.social with its Director, @bengoldacre.bsky.social, for a conversation on evidence, transparency, and why better data is the starting point—not the end point—of better care

That brings the 2025 Bennett Institute Medicines Symposium to a close. A big thank you to everyone who joined us. It has been a fantastic two days and we look forward to continuing this work with you.

Morning Oxford. We will be kicking off day 2 with a demo of our tools. OpenSAFELY, OpenPrescribing, OpenPrescribing Hospitals, OpenCodelists and OpenCodeCounts.

Congratulations to all of the winners of the Bennett Prize in OpenPrescribing. You can read more on our LinkedIn and we will be sharing more on our blog over the coming days. www.linkedin.com/posts/bennet...

💊 New research from @bennettoxford.bsky.social finds wide variation in how long repeat prescriptions last across England, with durations ranging from 28 to 84 days depending on region, practice & software. Longer prescriptions could save time for patients & the NHS 👩‍⚕️

Save the date: 10-11 December 2025 We'll be hosting a symposium on medicines, NHS data, and open research. Here's more info, and a chance to sign up for updates: www.bennett.ox.ac.uk/events/2025-...

We tried to do some formulary review work for a tiny sub-set of info about antidepressants in an undergrad project back in 2022. Just trying to map which were the live formularies and which one applied to different geographic regions was very hard (thanks to repeated NHS reorganisations) (1/2)

We had some thoughts about formularies

Lots going on

And in other news

We shared our OpenPrescribing Hospitals beta with the folks at the Clinical Pharmacy Congress, and the response was very positive! Here's a short post from @brianmackenna.bsky.social with more info - www.bennett.ox.ac.uk/blog/2025/06...

We're adding hospital prescribing data to our hugely popular openprescribing data platform. So... What does NHS hospital prescribing data look like? As ever, our team culture is to build, but also to document, all in the open. Here is a deep deep dive... www.bennett.ox.ac.uk/blog/2025/03...

How often do you go to the doctor for your regular prescription? Every month? Every two months? Twice a year? Once a year? We ran the numbers. New paper out in @bjgp.bsky.social 👇 doi.org/10.3399/BJGP...

Great BBC news story about new developments at OpenSAFELY, securely provisioning GP data to researchers with innovative methods to protect all patients' privacy, and building out to support mental health research at scale. www.bbc.co.uk/news/article...

I'm delighted to say our highly secure and productive OpenSAFELY platform has received a further £17 million in funding from Wellcome, including for a new mental health data project. More here, and clips from Today on Radio4 this morning too! www.bennett.ox.ac.uk/blog/2025/02...

We were on the Today Programme this morning! Here's a blog post from Ben about why OpenSAFELY is in the news today, and how a total of £17 million of new funding from Wellcome is going to be a game-changer: www.bennett.ox.ac.uk/blog/2025/02...

We've started work on a new service, OpenPrescribing Hospitals - using existing hospital medicines data to help optimise prescribing in hospitals in the future. Here's a sneak peek of what's coming, and some useful background context: www.bennett.ox.ac.uk/blog/2025/01... #OpenPrescribing

You too could read our OpenSAFELY book while eating snacks. We still have a few copies to give away! Here's how to get one: www.bennett.ox.ac.uk/blog/2025/01... #OpenSAFELY

We’re publishing our printed book, “The past, present and future of OpenSAFELY” as a series of blog posts. But we also have some copies of the book itself to give away, for free! The first blog post in the series tells you how to get a copy: www.bennett.ox.ac.uk/blog/2025/01... #OpenSAFELY

We are hiring a tech lead! We build high impact national health data infrastructure that is open, productive, and beautiful - like our OpenSAFELY - in a truly mixed team, where software developers and researchers all share skills, status, knowledge, and best practice! my.corehr.com/pls/uoxrecru...

The Causal Inference in #IDEpi Workshop provided great insight and discussion thanks to input from various speakers! @wjchulme.bsky.social of @bennettoxford.bsky.social @ox.ac.uk introduced us to challenges in estimating vaccine effectiveness in routine data #OpenSAFELY (1/3)

For those of you who couldn't come to our OpenSAFELY Community Symposium - now you can catch up on the whole thing www.bennett.ox.ac.uk/blog/2024/12...

People don't realise how significant this project is. It solves many of the major technical, ethical and research challenges of using EHR data for research. This approach should be much more widely adopted for making use of all the data we collect (at great expense!) in healthcare.

We did a conference @bennettoxford.bsky.social OpenSAFELY Community Symposium 2024 It was great THANK YOU to those who came If you couldn't make it....................... Read our conference booklet Sneak a peak at speaker videos www.bennett.ox.ac.uk/blog/2024/12...
