We (NHSX and Dept for Health and Social Care) have published our draft Data Strategy: #DataSavesLives.
Want to know what’s in it? Thread below:

Went into the centre of town yesterday. Remember book stores? They’re still there! It was wonderful.
I went for a walk with a good friend who I hadn’t seen since before the pandemic started. We stopped by the COVID memorial wall, showing heart after heart after heart, each recognising someone who has died from this awful disease. It was… well, “striking” doesn’t begin to cover it.
A project for this rainy bank holiday. An arduino robot! (Still in need of debugging.)
We went for a walk today, and everything was green and GLORIOUS.
This week's @tag meetings included:
•Updating the multi-screen window placement API, for ex: slides on one screen & speaker notes on other
•App history, so that forward & back buttons in a web app can navigate within the app instead of away from it

This week, we focused on our design principles in our @tag mtgs:
• Fast-evolving crypto algorithms in slower-evolving features
• Using more bikeshed syntax. (Yes, our spec-generating tool is called bikeshed. It matters what shade of blue that is!)

This wek’s @tag meetings included:
• WebXR hit testing, so you can cast a ray into the real world & return a list of intersection points for that ray against whatever world understanding the underlying system gathers

Paper: The epidemiological impact of the NHS COVID-19 App. 2021. Wymant, Ferretti et al.
"We estimated that for every 1% increase in app users, the number of infections can be reduced by 0.8% (from modelling) or 2.3% (from statistical analysis)."
Technical documentation for the #NHSCOVID19app’s risk scoring algorithm:
#OpenSource code for the #NHSCOVID19app:
• System & architecture https://github.com/nhsx/covid19-app-system-public
• Android https://github.com/nhsx/covid-19-app-android-ag-public
• iOS https://github.com/nhsx/covid-19-app-ios-ag-public
Vulnerability Disclosures: https://hackerone.com/nhscovid19app?type=team
The #NHSCOVIDapp is now also interoperable — compatible with other contact tracing apps across the UK, protecting users who travel to Scotland, Jersey, Northern Ireland or Gibraltar.
• The #NHSCOVID19app is continually improved; has had a series of updates since its launch in September 2020, including an update to the risk scoring algorithm to utilise Google/Apple's API Mode 2 which better estimates distance based on Bluetooth signal strength.
• Users have checked into a venue over 103 million times
• 253 venues have been identified ‘at risk’ after an outbreak since 10 Dec, triggering ‘warn & inform’ alerts to app users who had checked into those venues. A ‘w&i’ notification is different to an instruction to isolate
• The #NHSCOVID19app has been downloaded 21.63 million times, representing 56% of the eligible population (age 16+ with a smartphone)
• Research by scientists at @TuringInst & @UniofOxford shows for every 1% ⬆️ in app users, the # of coronavirus cases in the population ⬇️ 2.3%
New stats on the #NHSCOVID19app:
• Approx 600,000 cases have been prevented by the app since Sept
• Over 1.7 million app users across England & Wales have been advised to isolate by the app after close contact with someone who goes on to test positive
