Lockdown during early pandemic saved lives.
There has been a lot of discussion here about the good vs bad of lockdowns.
This study is an attempt to quantify some of the figures from the first lockdown in the USA.
Other studies have evaluated an economic cost. This one attempts to evaluate lives saved.
Unfortunately the conclusion seems to be that every situation is different so a lockdown may turn out to be worthwhile, or not, but maybe cannot be evaluated till after the event.
But they do make a case that the first lockdown early in the pandemic was probably worthwhile but a lockdown at this current stage of the pandemic may not be.
Here are some snippets, but the full report is available at the link above.
A new University of Michigan-led study shows the early lockdowns implemented in the first six months of the COVID-19 pandemic saved lives––but the decision to use lockdowns is much more nuanced and the research shouldn't be used to justify lockdowns now or to retroactively endorse that approach, said health economist Olga Yakusheva, associate professor at the U-M School of Nursing.
“This is the first known paper to measure the effect of pandemic lockdown mitigation measures on lives saved and lost, as opposed to typical economic evaluations, which examine the cost per life saved”, she said.
The study found that from March through August 2020, implementing widespread lockdowns and other mitigation in the United States potentially saved more lives (866,350 to 1,711,150) that the number of lives potentially lost (57,922 to 245,055) that were attributable to the economic downturn.
However, the results are more ambiguous when looking at the quality-adjusted life expectancy added by lockdown (4,886,214 to 9,650,886) vs. quality-adjusted life years lost (2,093,811 to 8,858,444) due to the economic downturn.
This is because many of the people saved were high-risk older adults with multiple illnesses and fewer healthy years left to live, while those most impacted by the economy were younger people in service jobs and other lower-paying occupations who found themselves without employer-provided health insurance and, in many cases, unable to pay for health care or even life-saving medications. A quality adjusted life year is one year of life in perfect health.
The study, published in PLOS One, should not be used to justify more lockdown measures, Yakusheva said. Nor is it a retroactive endorsement of the strict economic lockdown approach the U.S. imposed during the first six months of the pandemic.
"We evaluated the full packet of public health measures as it was implemented in the beginning of the pandemic, but lesser mitigation measures may have worked just as well to reduce lives lost," Yakusheva said. "The fact is, we just will never know. At the time, we had to work with the information that we had. We knew the pandemic was deadly, and we did not have therapeutics or a vaccine."
The situation has changed dramatically since the pandemic began, and we have more tools to battle the virus, Yakusheva said. Vaccines and therapeutics are available, as are other mitigation measures.
