Association between the number of comorbidities and all-cause mortality during the COVID-19 pandemic: A Danish nationwide, retrospective cohort study.

ABSTRACT:

Objectives

Chronic illnesses have been linked to elevated risks of hospitalization and mortality during the COVID 19 pandemic. While many studies have examined how specific comorbidities influence outcomes among hospitalized COVID 19 patients, less is known about how the pandemic affected all cause mortality among comorbid individuals in the general population. Our objective is to assess how the number of pre pandemic comorbidities interacted with COVID 19 and whether all cause mortality risks for individuals with comorbidities changed during the pandemic.

Methods

This is a population-based retrospective cohort study, where we analyzed the entire Danish population aged 45 years and older using nationwide registry data. We examined COVID 19 specific and non COVID 19 mortality
