Prevalence of multiple risk factors for poor outcomes associated with COVID-19 among an elderly Australian population.

Abstract

BACKGROUND AND OBJECTIVES\nIncreasing age, male sex and various chronic conditions have been identified as important risk factors for poor outcomes from COVID-19. The aim of this study was to examine the prevalence of risk factors for poor outcomes due to COVID-19 infection in an older population.\n\n\nMETHOD\nThe proportion of the population with one or more risk factors and the prevalence of individual risk factors and multiple risk factors were calculated among Department of Veterans Affairs (DVA)\xa0clients aged ≥70 years.\n\n\nRESULTS\nThere were 103,422 DVA clients included. Of these, 79% in the community and 82% in residential aged care had at least one risk factor for poor outcomes from COVID-19. Hypertension was most prevalent, followed by chronic heart and airways disease. Over half had ≥2 risk factors, and one in five had ≥3 risk factors across multiple body systems.\n\n\nDISCUSSION\nA substantial proportion of older Australians are at risk of poor outcomes from COVID-19 because of their multimorbid risk profile. These patients should be prioritised for proactive monitoring to avoid unintentional harm due to potential omission of care during the pandemic.
