BACKGROUND: Various patient demographic and clinical characteristics have been associated with poor outcomes for individuals with coronavirus disease 2019 (COVID-19). To describe the importance of age and chronic conditions in predicting COVID-19 related outcomes.
METHODS: Search strategies were conducted in PubMed/MEDLINE. Daily alerts were created.
RESULTS: A total of 28 studies met our inclusion criteria. Studies varied broadly in sample size (n=21 to more than 17,000,000). Participants mean age ranged from 48 years to 80 years and the proportion of male participants ranged from 44%-82%. The most prevalent underlying conditions in patients with COVID-19 were hypertension (range: 15% - 69%), diabetes (8% - 40%), cardiovascular disease (4% - 61%), chronic pulmonary disease (1% - 33%), and chronic kidney disease (range 1% - 48%). These conditions were each associated with an increased in-hospital case fatality rate ranging from 1% to 56%. Overall, older adults have a substantially higher case fatality rate (CFR) as compared with younger individuals affected by COVID-19 (42% for those < 65 vs 65% > 65 years ). Only one study examined the association of chronic conditions and the risk of dying across different age groups; their findings suggested similar trends of increased risk in those < 65 and those > 65 years as compared to those without these conditions.
CONCLUSIONS: There has been a traditional, single condition approach to consideration of how chronic conditions and advancing age relate to COVID-19 outcomes. A more complete picture of the impact of burden of multimorbidity and advancing patient age is needed.
