Unequal cost of COVID-19 deaths laid bare by study

New research by academics from the Universities of Manchester and York has highlighted how in its first year, the impact of the Covid-19 pandemic on England and Wales was far worse for some than others.
The study vividly depicts health inequalities in terms of excess years of life lost – a measure of premature mortality measuring the extra years lost during the pandemic compared with previous years.
The measure, the first time it has been used in the context of COVID-19, accounts for both the number of deaths and the age at which those deaths occurred and allows comparison between causes of death across population groups.
Published in PLOS Medicine, one of the world’s leading journals, the study shows that the most deprived areas reported much higher numbers in excess years of life lost, even after adjusting for population size. Excess years of life lost per 100,000 population ranged from 916 for the least deprived quintile to 1,645 for the most deprived.
And there was also marked variability in both Covid-19 related and all-cause excess years of life lost by region, with the highest rates in the North West of England, which was three times as high as those in the South West of England.
Between March 2020 and December 2020, there were an estimated 763,550 excess years of life lost, equivalent to a 15% increase compared to the equivalent time period in 2019. 85% of the deaths were directly attributed to COVID-19 or another respiratory disease.
The impact of deprivation on mortality was greatest in younger people: for all-cause mortality in the most deprived areas, 15 to 44-year-olds were estimated to have had 480 excess deaths, compared to 42 in the most affluent, or over 11 times as many. Adjusting for population sizes, ratios of all-cause excess deaths ranged from 2.7 in 15 to 45-year-olds to 1.6 in those aged 85 or over.
For mortality caused directly by COVID-19 and respiratory illness, in the most deprived areas, 15 to 44-year-olds were estimated to have had 268 excess deaths, compared to 51 in the most affluent, over 5 times as many. Adjusting for population size, ratios of Covid-19 excess deaths ranged from 5 in 15 to 45-year-olds to 1.6 (again) in those aged 85 or over.
More years of life were lost for men on average, 10.5 in COVID/respiratory deaths and 10.8 in all-cause deaths, compared to 9.5 and 8.2 for women, respectively.
The pandemic exacerbated longstanding socioeconomic inequalities, with the ratio of observed years of life lost for the most deprived fifth of areas compared to the most affluent increasing from 1.56 in 2019 to 1.64 in 2020.
Professor Evan Kontopantelis from The University of Manchester said: “The pandemic widened pre-existing health inequalities across England and Wales: regions and social groups with the highest baseline mortality rates experienced the greatest impact on years of life lost.
“Linked to this, we think the impact of the pandemic may have been higher than previously thought on the most deprived areas of England and Wales, with more younger people dying directly or indirectly from COVID-19 in these areas.”
Professor Tim Doran from the University of York said: “Our findings support the notion that Years of Life Lost can be more informative for determining unmet needs and informing policy for this or future pandemics.
“In particular, it could provide vital information to aid the targeting of vaccines, financial aid, and social support during this and future pandemics.”
