So far, the most complete analysis of changes in hospital mortality in the United States reveals this: “With the development of the epidemic, the number of deaths has decreased. This may be due to changes in hospital burden and treatment options.”
In the first few months of the pandemic, the high hospital mortality rate for Covid-19 in the United States fell by more than one-third by June 2020, marking a further decline until November last year.New analysis published in Jama network is open Reviewed by researchers from the Institute of Health Metrics and Evaluation at the University of Washington More than 20,000 patients He was hospitalized in a Covid-19 hospital in the United States from March 2020 to November 2020.
The survey found that the death rate in March and April was 19.1%, the death rate in May and June was 11.9%, the death rate in July and August was 11%, and the death rate from September to November was 10.8%. . “Compared with March and April -Indicate the author of the study- Covid-19 hospital mortality By May and June, they were down 38%, And reduce further by November.” The study also pointed out that nearly one-third of patients are hospitalized in the intensive care unit, and one-fifth of patients require mechanical ventilation.
However, when looking for possible reasons for this change, the researchers pointed out that factors such as age, gender, other previous conditions, and the severity of the disease at the time of admission cannot fully explain the decline in mortality. “Understanding why the mortality rate is changing is important for doctors working to improve the outcome of Covid-19 hospitalized patients The lead author of the study, said Dr. Gregory Rose, associate professor of medicine at the Institute of Health Metrics and Evaluation at the University of Washington. Need further analysis to understand The driver is more precise, But a crucial topic is the need for information sharing and the identification of best practices in hospitals to prevent the death rate from rising again, especially during the Covid-19 wave that may occur in the future“.
Data analysis showed that there were only minor changes in the characteristics of patients who died during the study, including a slight decrease in age, an increase in the proportion of women, and an increase in body mass index. “Our results suggest that the decline in mortality may be due to Change hospital burden and treatment -Rose-explain. C.n The more forms of circulation, many countries are still struggling with hospital overload and resource scarcity. The more we know, the better“.
