I've always fancied myself as a non-sectarian Thought for the Day speaker. Decades ago I got into correspondence with Rabbi Lionel Blue and he agreed we should have some non-religious 'thoughts' in that slot.

Though I do always turn off the recorder at the end and ask them if there’s anything else they want to share! Can often charm them into letting me turn it on again and them saying the gem again

Stephen Fry: β€œI’m deeply worried by the darkening shadow that’s going over the world, a shadow that we have to call fascism”

Laura Kuenssberg: β€œYou would use that word?”

Stephen Fry: β€œOh absolutely. It’s a cult of power; and power only speaks to power”

Dr Abell at the podium alongside a slide with the titled 'A science informed practice'

"There is no tooth fairy. Nor is there any formal framework or model or checklist of things to do (or questions to ask) that will take you systematically through everything you need to do to 'implement' a particular piece of evidence in a particular setting"

A slide titled 'A cautionary tale: lgnaz Semmelweis (1818-1865)' and the wording
WHAT intervention or innovation
x HOW Implementation strategies
x Effective implementation
x Enabling context

=OUTCOMES

Semmelweis didn't consider the how-how to get people on board how to change their behaviour, how to address their scepticism
Semmelweis didn't consider the context -how he could have understood and address the prevailing barriers

Barrier
Implementation Science Strategy
Doctors didn't believe in handwashing
Use behavior change models (e g COM B) to target beliefs and norms

No leadership support
Engage hospital leaders as champions

No policy reinforcement
Mandate hand hygiene via hospital regulations

Resistance to new practice
Use audit & feedback to show improved outcomes

Lack of training
Build handwashing into medical education

Don't be like Semmelweis!

@drbridgetabell.bsky.social citing @trishgreenhalgh.bsky.social in her address at #SPICA26 about implementation science! And using Semmelweiss as the cautionary tale of how *not* to implement healthcare change. Semmelweiss used to write angry letters to colleagues accusing them of being murderers. πŸ€¦πŸ»β€β™€οΈ

Don’t let mega-constellation-building billionaires steal your night sky Satellites are wonders of modern technology that have improved all of our lives. But having more than a million of them in orbit could destroy our view of the heavens and seriously damage our planet

Elon Musk has already started plans to launch a million satellites.

Yes. A MILLION.

This is a colossally bad idea, and it's not too late to make your voice heard. I explain everything:

BREAKING:

The Justice Department just posted online three FBI interviews that had been missing from the massive trove of Epstein files initially released.

They're related to unsubstantiated sexual assault allegations against Donald Trump.
