A global perspective
The United States experienced high mortality linked to COVID-19, as well as high all-cause mortality, compared with 18 other countries, as reported in the study by University of Pennsylvania and Harvard University researchers.
The United States ranked third, with 72 deaths per 100,000 people, among countries with moderate or high mortality. Although perhaps not surprising given the state of SARS-CoV-2 infection across the United States, a question remains as to what extent the relatively high mortality rate is linked to early outbreaks vs “poor long-term response,” the researchers note.
Alyssa Bilinski, MSc, and lead author Ezekiel J. Emanuel, MD, PhD, chair of the Department of Medical Ethics and Health Policy at the University of Pennsylvania Perelman School of Medicine in Philadelphia, calculated the difference in COVID-19 deaths among countries through Sept. 19, 2020. On this date, the United States reported a total 198,589 COVID-19 deaths.
They calculated that, if the US death rates were similar to those in Australia, the United States would have experienced 187,661 fewer COVID-19 deaths. If similar to those of Canada, there would have been 117,622 fewer deaths in the United States.
The US death rate was lower than six other countries with high COVID-19 mortality in the early spring, including Belgium, Spain, and the United Kingdom. However, after May 10, the per capita mortality rate in the United States exceeded the others.
Between May 10 and Sept. 19, the death rate in Italy was 9.1 per 100,000, vs 36.9 per 100,000.
“After the first peak in early spring, US death rates from COVID-19 and from all causes remained higher than even countries with high COVID-19 mortality,” the researchers note. “This may have been a result of several factors, including weak public health infrastructure and a decentralized, inconsistent US response to the pandemic.”
“Mortifying and motivating”
Woolf and colleagues estimate that more than 225,000 excess deaths occurred in recent months; this represents a 20% increase over expected deaths, note Harvey V. Fineberg, MD, PhD, of the Gordon and Betty Moore Foundation, in an accompanying editorial in JAMA.
“Importantly, a condition such as COVID-19 can contribute both directly and indirectly to excess mortality,” he writes.
Although the direct contribution to the mortality rates by those infected is straightforward, “the indirect contribution may relate to circumstances or choices due to the COVID-19 pandemic: for example, a patient who develops symptoms of a stroke is too concerned about COVID-19 to go to the emergency department, and a potentially reversible condition becomes fatal.”
Fineberg notes that “a general indication of the death toll from COVID-19 and the excess deaths related to the pandemic, as presented by Woolf et al, are sufficiently mortifying and motivating.”
“Profound human toll”
“The importance of the estimate by Woolf et al – which suggests that for the entirety of 2020, more than 400,000 excess deaths will occur – cannot be overstated, because it accounts for what could be declines in some causes of death, like motor vehicle crashes, but increases in others, like myocardial infarction,” write Howard Bauchner, MD, editor in chief of JAMA, and Phil B. Fontanarosa, MD, MBA, executive editor of JAMA, in another accompanying editorial.
“These deaths reflect a true measure of the human cost of the Great Pandemic of 2020,” they add.
The study from Emanuel and Bilinski was notable for calculating the excess COVID-19 and all-cause mortality to Sept. 2020, they note. “After the initial peak in early spring, US death rates from COVID-19 and from all causes remained higher than rates in countries with high COVID-19 mortality.”
“Few people will forget the Great Pandemic of 2020, where and how they lived, how it substantially changed their lives, and for many, the profound human toll it has taken,” Bauchner and Fontanarosa write.
The study by Woolf and colleagues was supported by National Center for Advancing Translational Sciences, the National Institute on Aging, and the National Institute of Allergy and Infectious Diseases. The study by Bilinski and Emanuel was partially funded by the Colton Foundation. Woolf, Emanuel, Fineberg, Bauchner, and Fontanarosa have disclosed no relevant financial relationships.
