According to a new study, the death rates for ICU patients with coronavirus decreased by one-third, partly due to improved hospital treatment.
The global analysis of 24 COVID-19 observational studies, the disease caused by the novel coronavirus, was published in the journal Anaesthesia on Wednesday.
The research, led by Professor Tim Cook of the Royal United Hospitals Bath in England, found that the overall mortality rate of COVID-19 patients in intensive care units ( ICUs) fell from nearly 60% since the end of March to 42% at the end of May. The rate in all of Europe, Asia, and North America was not significantly different.
Study authors gave many theories, including “rapid learning that has taken place on a global scale due to the prompt publication of clinical reports early in the pandemic.” They also indicated that hospital ICUs might have been under greater strain early in the pandemic.
Doctors reported success in understanding enough about the highly infectious virus to have a clearer understanding of key problems for many patients, while more research continues to be done on drug development and preventive vaccine development.
The researchers said their results may reflect the time taken to show up in the data for long ICU stays, noting that nearly a third of UK ICU admissions lasted more than 28 days and 9 percent stayed more than 42 days.
The results indicated that the recent COVID-19 ICU mortality rate of about 40% is still well above 22% for other viral pneumonia.
According to the doctors,
“Optimistically, as the pandemic progresses, we may be coping better with COVID-19.”
