The previously hidden figures, covering all NHS trusts in England, showed that as of last week, only 44% of those classified as Covid patients had tested positive for the virus by the time they were admitted to hospital. Despite broad public testing for the disease, an incredible 56% of Covid hospitalisations involve already-admitted patients who were administered routine Covid tests, the Telegraph reported. Forty-three percent of Covid-positive patients were identified within two days of admission, while 13% were flagged in the following days and weeks.
According to the outlet, health officials were instructed last month to begin placing Covid patients into two categories: those who were in hospital primarily because of the virus, and those who were admitted for other reasons. However, the NHS has so far withheld this data from the public.
With the majority of Covid patients being diagnosed after admission – in some cases weeks later – the leaked data points to the possibility that the virus may only have a minor or negligible role in many hospitalisations blamed on coronavirus.
The leaked figures also suggest that a large number of Covid hospitalisations are the result of nosocomial transmission, meaning that healthcare facilities – rather than restaurants, stadiums, schools, or other public venues – may be driving up infections requiring medical care.
Ultimately, the NHS leak indicates that many Covid patients are actually in hospital for non-Covid reasons, especially when one considers the widespread and regular use of PCR tests, Professor Carl Heneghan, director of the Centre for Evidence-Based Medicine at the University of Oxford, told the Telegraph.
“When people hear about hospitalisations with Covid, they will assume that Covid is the likely cause, but this data shows something quite different – this is about Covid being detected after tests were looking for it,” he said, adding that the current data being fed to the public could lead to “false conclusions” and exaggerate the virus’ actual impact on the NHS.
Heneghan described the leaked figures as “incredibly important” and urged the government to stop withholding such data.
Tory MP Graham Brady issued a similar call for greater transparency, noting that even after 18 months of the health crisis, the government has failed to make detailed information about hospital admissions publicly available on a regular basis.
