Objective: to map the scientific knowledge about COVID-19 in older adults., Method: this is a scoping review literature review. A search was performed in the PubMed, CINAHL, Web of Science and LILACS databases. Original articles that answered the guiding question were included: what scientific knowledge is available in the world about COVID-19 in older adults?, Results: thirty-one articles were included, most of them carried out in China (n=23) and with a retrospective design (n=13) and case studies/case series (n=13). Based on the findings, six thematic categories emerged: clinical signs and symptoms (n=12), other information (n=9), adverse outcomes/complications resulting from COVID-19 (n=8), age relationship and greater severity of COVID-19 (n=8), variables related to death by COVID-19 (n=8), and diagnostic findings (n=8)., Conclusion: the findings reinforce older adults' greater vulnerability to the worsening of COVID-19, as well as to complications resulting from the disease, including the greater occurrence of death.

Objective: to investigate the association between frailty with hospitalization and institutionalization in a follow-up study of elderly residents., Method: the follow-up study was performed in 2008 and 2013 with elderly of both genders, aged 65 years and older who were living in the community-dwelling. The sampling procedure performed was probabilistic, with dual-stage clustering. In 2008, 515 elderly people were interviewed and, in 2013, 262. We used the socioeconomic and demographic data, self-reported morbidity, specific data of hospitalization and institutionalization. Frailty was measured by the Edmonton Frail Scale (EFS), and functional capacity through the Functional Independence Measure., Results: we found the mean gross EFS score was higher among resident elderly who were hospitalized and institutionalized and was statistically significant in both investigated years., Conclusion: the confirmation of association between frailty and hospitalization and institutionalization reinforces the importance of the subject, and highlights frailty as an important tool for risk estimates for these adverse events.
