Abstract

Abstract: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) places older adults at increased risk of hospitalization and mortality due to coronavirus disease 2019 (COVID-19). To date, research and regulatory data describe adults 65 years and older, with few reporting on characteristics specific to older adults 85 and older ("oldest-old"). A consecutive 12-month case series including 1, 510 oldest-old patients hospitalized with SARS-CoV-2 is presented to describe clinical characteristics, Intensive Care Unit (ICU) utilization and in-hospital mortality from 26 urban, suburban and rural-serving hospitals in an integrated health system in Texas. Known predictors of poor prognosis in COVID-19 include older age, male sex, metabolic risk factors (dyslipidemia, obesity, diabetes) and respiratory failure requiring oxygen support. Compared with hospitalized patients < 85 years, oldest-old patients more often had 4+ chronic conditions (31% vs 12%, p< 0.0001), but less often had metabolic risk factors associated with increased risk for mechanical ventilation and mortality. Specifically, diabetes prevalence was similar between age groups (27% oldest-old vs 30%, NS), while obesity prevalence was lower (18% oldest-old vs 55%, p< 0.0001). Oxygen support requirements were largely similar to the general population, with 4 of 5 hospitalized patients requiring oxygenation support. Of 1, 510 oldest-old patients hospitalized for SARS-CoV-2, 269 (18%) required admission to an ICU, 1, 206 (80%) required oxygen support, and 1, 221 (81%) survived. Following hospitalization, 78% required supportive care, including hospice (15%). Hospitalization characteristics across the lifespan suggest an accelerated and compounded need for ICU recovery and post-hospitalization rehabilitation attributed to the COVID-19 pandemic.
