COVID-19: Death Data in England – Update 25th April

April 25, 2020

Jason Oke, Carl Heneghan


Summary  

Consistent with previous analyses, the peak day of deaths was the 8th of April. The structure of the data is similar across the regions, with the peak in London on the 4th of April, four days ahead of the rest of the country, the 8th of April.

NHS England releases data at 2 pm each day and reports daily count up to the previous day as well as a total figure. We wrote about the problems with reconciling the different data here:

Today’s reported figure is 711 deaths in hospitals in England. These deaths are distributed back to the 11th of March.

There are deaths reported for 35 different dates that are from outside the uncertainty region of the revised upward zone.

Of the 711, deaths 486 (68%) occurred in the last 7 days (in the uncertainty zone), and 225 (32%) deaths occurred between the 11th March and the 17th April.

This is the second day we have seen an increase in the number of deaths reported that occurred over a week ago, the majority of which occurred over 2 weeks ago. We do not know the reason for this.

These deaths are  distributed across the following days:

and are distributed by region as follows (Today we have added on the South West)

The figure shows the reporting of deaths by  NHS England underestimate those reported by ONS  – One of the reasons for this is NHS England’s data does not include deaths reported outside hospitals.

Daily reports generally add more to the previous two days  (up to a maximum 300 deaths), and can add back to the previous week’s counts (the grey shaded area in figure  2).
