Daily COVID Admissions in England over time
Absolute Change in COVID Admissions over time
Definitions changed over time. Previous definitions were: *COVID daily confirmed on admission, and COVID -19 confirmed on admission COVID daily admissions diagnosed within 24 hours (see slide set 30th April and slide set 5th May). It is not clear whether ‘admission’ means admitted to hospital with COVID, admitted and diagnosed with COVID while in a hospital or infected with COVID while an inpatient.
Critical Care Bed Occupancy across the UK continue to decline:
Includes both Nightingale hospitals and Dragon’s Heart/Ysbyty Calon y Ddraig field hospital
For Wales ventilator and critical care beds are identical. For Scotland, mechanical ventilator beds and critical care beds are identical (figures include a small number of patients who are not on mechanical ventilation). For England, the denominator is the number of beds capable of delivering mechanical ventilation. For Northern Ireland, the denominator is the number of beds capable of delivering mechanical ventilation, based on its current maximum surge capacity.
People in Hospital in England
Absolute change and moving average for people in hospital
The absolute change shows an early trend for very high numbers in hospital beds with an absolute increase over 1,000 per day occurring on six separate occasions. However, it is notable that there was a rapid rebound such that by the 11th April the figures saw rapid declines in people occupying beds – the 17th April saw the maximal reduction with 928 fewer beds occupied by COVID patients.
Explanations for changes include:
1) Some people admitted into hospital died;
2) Some admitted idid not need to be in hospital and were therefore rapidly discharged;
3) The data on admissions shows that the peak of admission occurred on the 1st of April and then declined
It is likey the rapid decline and then stabilisation of the numbers occupying beds is a combination of all three.
