Death rates from people with severe COVID-19 in hospital have dropped to around a half of the rate at the peak of the pandemic, new research has revealed.
An analysis of over 21,000 hospital admissions, published in Critical Care Medicine, found a significant drop in death rates for both high dependency unit admissions and intensive care admissions between March and the end of June.
The team was led by the University of Exeter and involved the University of Warwick, and was supported by The Alan Turing Institute. They found death rates were highest in late March, at 26 per cent among people admitted to high dependency units, and 41 per cent among people admitted to intensive care. For June admissions, death rates had dropped to 7 per cent among high dependency unit admissions, and to 21 per cent among intensive care admissions.
Dr. John Dennis, of the University of Exeter Medical School, who led the research, said: “Importantly, we controlled for factors including age, sex, ethnicity and other health conditions such as diabetes. This suggests the improvement in death rates in more recent months is not simply due to younger, or previously healthier, people being admitted to critical care. A number of factors are likely to be at play here, including improved understanding of how to manage COVID-19 amongst doctors, and the introduction of effective treatments.”
The team accessed national data from adults admitted to critical care via the COVID-19 Hospitalisation in England Surveillance System (CHESS), collected by Public Health England. They looks at how the proportion of people with COVID-19 dying within 30 days of admission changed over March until the end of June.
