Pete Weatherby KC highlights concerns about Covid-19 testing figures and public trust
10 October 2023
Pete Weatherby KC today drew attention to criticisms of the presentation of testing statistics by the UK Government during the Covid-19 pandemic.
During the evidence of Professor Sir lan Diamond, National Statistician at the UK Statistics Authority, Pete directed the attention of the Inquiry to a letter from 2 June 2020 – Sir David Norgrove response to Matt Hancock regarding the Government’s COVID-19 testing data.
The letter was written in the context of Mr Hancock’s testing targets of 100,000 tests per day by end of April 2020 and 200,000 tests per day by end of May 2020.
In the letter Sir David says that the Government’s presentation of the testing statistics meant that the figures were ‘far from complete and comprehensible’.
The letter outlines two main purposes of publishing testing data as being:
- To help understanding of the epidemic, alongside the ONS survey, showing how many people are infected, or not, and their relevant characteristics.
- To help manage the test programme, to ensure there are enough tests, that they are carried out or sent where they are needed and that they are being used as effectively as possible.
Pete highlighted the fact that Sir David felt the Government figures had ‘limited value for the first purpose’. And that ‘the statistics and analysis serve neither purpose well.’ Sir David also noticed that the aim of the reported figures ‘seems to be to show the largest possible number of tests, even at the expense of understanding’.
Pete told the Inquiry that Sir David felt that the presentation of the figures gave an ‘artificially low impression of the proportion of tests returning a positive diagnosis’ because the figures were reached by adding together tests carried out and tests posted out but described ‘misleadingly’ as solely the number of tests carried out.
Pete concluded by reading some of the latter passages from the letter: ‘…the testing statistics still fall well short of [the Code of Practice for Statistics] expectations. It is not surprising that given their inadequacy data on testing are so widely criticised and often mistrusted.’
‘…I am sure you would agree that good evidence, trusted by the public, is essential to success in containing the virus.’
