Background: The COVID-19 pandemic is responsible for increasing deaths globally Most estimates have focused on numbers of deaths, with little direct quantification of years of life lost (YLL) through COVID-19 As most people dying with COVID-19 are older with underlying long-term conditions (LTCs), some have speculated that YLL are low We aim to estimate YLL attributable to COVID-19, before and after adjustment for number/type of LTCs Methods: We first estimated YLL from COVID-19 using standard WHO life tables, based on published age/sex data from COVID-19 deaths in Italy We then used aggregate data on number/type of LTCs to model likely combinations of LTCs among people dying with COVID-19 From these, we used routine UK healthcare data to estimate life expectancy based on age/sex/different combinations of LTCs We then calculated YLL based on age, sex and type of LTCs and multimorbidity count Results: Using the standard WHO life tables, YLL per COVID-19 death was 14 for men and 12 for women After adjustment for number and type of LTCs, the mean YLL was slightly lower, but remained high (13 and 11 years for men and women, respectively) The number and type of LTCs led to wide variability in the estimated YLL at a given age (e g at ≥80 years, YLL was 10 years for people with 0 LTCs, and 3 years for people with ≥6) Conclusions: Deaths from COVID-19 represent a substantial burden in terms of per-person YLL, more than a decade, even after adjusting for the typical number and type of LTCs found in people dying of COVID-19 The extent of multimorbidity heavily influences the estimated YLL at a given age More comprehensive and standardised collection of data on LTCs is needed to better understand and quantify the global burden of COVID-19 and to guide policy-making and interventions
