The goal of this study was to identify changes in cognitive and functional capacity after hospital discharge in those infected with COVID-19 who were admitted to the ICU. This is a prospective cohort study carried out with individuals who were admitted to a hospital, from July 2021 to May 2022. The evaluations happened in three moments: at hospital discharge, 30 days after discharge and 90 days after discharge. The instruments applied are the following: handgrip dynamometer, Montreal Cognitive Assessment Basic questionnaire (MoCA-B), Barthel Index (BI), timed up and go test (TUG), hospital anxiety and depressive scale (HADS) and 36-Item Short Form Health Survey questionary (SF-36). 74 individuals were eligible to participate in the study, 25 of which were followed for 90 days. Based on the results of the MoCA-b, there were no relevant cognitive changes after 3 months. According to the Barthel Index applied to each of the evaluations, the percentage of subjects that were classified as independent or minimally dependent was 48%, 92% then 96%, respectively, demonstrating that individuals can achieve a good degree of functional independence after 3 months. Despite that, the SF-36 demonstrated a score below the South Brazilian normal in some domains. The individuals studied did not present persistent cognitive changes after 3 months and functional capacity showed significant improvement during this period. However, when the assessment is about the self-perceived quality of life, the majority of domain values are still below expectations, deserving attention by the health professionals involved.
