The real benefit is that we now have NHS data infrastircture through OpenSAFELY that means we can re run the analysis whenever is needed

"We must no longer accept waiting years to understand disease burden"

As it says in this excellent linked editorial

We must no longer accept waiting years to understand disease burden
One of the most important advances to emerge from the covid-19 pandemic is the ability to measure population health at unprecedented scale and speed. Our study of time trends for long term conditions,...

There is important information about health inequalities. Briefly for example e.g. subgroup analyses, diagnosis rates for dementia have increased
above preC19 levels for people of white ethnicity and those from less deprived areas, but not for those from other ethnicities or more deprived areas

This information is really important for continued planning of NHS services.

The @bmj.com have used our data to make even more beautiful charts than we made!

Five years on, the recovery varies :

📊 Depression diagnoses are nearly 30% lower than expected (dropping since 2022). 🩸 In contrast, Chronic Kidney Disease (CKD) diagnoses have risen by ~35% above expected levels.

📉 What did we find?

Diagnosis rates fell sharply for all 19 conditions during the early pandemic.

For example lung diseases (asthma, COPD) and skin conditions (psoriasis, atopic dermatitis) were affected early on.

The scale is phenomenal.

Using anonymised data for 30 million people via the NHS England OpenSAFELY service, we tracked conditions ranging from Asthma & COPD to Heart Failure & Depression & and many more

Remember this is not just a paper that lives on a dusty shelf

Now over to you 👇

Go and check what andexanet alfa use looks like in your hospital on OpenPrescribing.

It hasn’t been withdrawn in the UK, and there may still be appropriate use cases.

This kind of transparency and rapid, reproducible analysis is essential if we’re serious about evidence-based and equitable care.

All operating in near real time - available on hospital wards throughout England for live ward round audits!

But this paper isn’t really about andexanet alfa.

It’s much bigger than that!
