Design outcomes

Primary

MeasureTime frameDescription
One-year utility score of health related quality of lifeThe outcome will be assessed 12 months after enrollment.The outcome will be assessed using the Brazilian version of the Euroqol-5D-3L (EQ-5D3L) questionnaire. The utility score derived from the EQ5D-3L ranges from 0 (death) to 1 (perfect health).

Secondary

MeasureTime frameDescription
Utility score of health related quality of life at 3, 6, and 9 monthsThe outcome will be assessed at 3, 6, and 9 months after enrollment.The outcome will be assessed using the Brazilian version of the Euroqol-5D-3L (EQ-5D3L) questionnaire. The utility score derived from the EQ5D-3L ranges from 0 (death) to 1 (perfect health).
Incidence of all-cause mortalityThe outcome will be assessed at 1, 3, 6, 9, and 12 months after enrollment.Incidence of all-cause mortality
Incidence of major cardiovascular eventsThe outcome will be assessed at 3, 6, 9, and 12 months after enrollment.Incidence of major cardiovascular events (composite endpoint of non-fatal stroke, non-fatal acute myocardial infarction, or cardiovascular death)
Incidence of hospitalizationsThe outcome will be assessed at 1, 3, 6, 9, and 12 months after enrollment.Incidence of all-cause hospitalizations
Prevalence of prolonged COVID-19 symptomsThe outcome will be assessed at 1, 3, 6, 9, and 12 months after enrollment.Prevalence of prolonged COVID-19 symptoms defined as presence of dyspnea, cough, fatigue, muscular weakness, chest discomfort, joint pain, anosmia, hair loss, brain fog, insomnia, among others)
Physical functional statusThe outcome will be assessed at 3, 6, 9, and 12 months after enrollment.Physical functional status as assessed by the modified Barthel index (score ranges from 0 to 100; higher scores indicate less functional dependence).
Prevalence of anxiety and depression symptomsThe outcome will be assessed at 3, 6, 9, and 12 months after enrollment.Prevalence of anxiety and depression symptoms as assessed by the Hospital Anxiety and Depression Scale (anxiety and depression scores range from 0 to 21, with higher scores indicating worse symptoms).
Prevalence of posttraumatic stress disorder symptomsThe outcome will be assessed at 3, 6, 9, and 12 months after enrollment.Prevalence of posttraumatic stress disorder symptoms as assessed by the Impact Event Scale-6 (scores range from 0 to 24 with higher scores indicating worse symptoms).
Instrumental Activities of Daily LivingThe outcome will be assessed at 3, 6, 9, and 12 months after enrollment.The outcome will be assessed using the Lawton & Brody Instrumental Activities of Daily Living Scale (the score ranges from 0 to 8, with higher scores indicating less dependence).
Incidence of return to work or studyThe outcome will be assessed at 3, 6, 9, and 12 months after enrollment.Incidence of return to work or study among patients that were working or studying at the moment of COVID-19 diagnosis.
Incidence of new symptomatic COVID-19 infectionThe outcome will be assessed at 3, 6, 9, and 12 months after enrollment.Incidence of new symptomatic COVID-19 infection defined as recurrence of COVID-19-related symptoms with a positive PCR test for SARS-CoV-2 90 days after the index infection.
Prevalence of cognitive dysfunctionThe outcome will be assessed at 3, 6, 9, and 12 months after enrollment.Prevalence of cognitive dysfunction as assessed by the Telephone Interview for Cognitive Status (TICS-m; scores ranging from 0 to 50 with lower scores indicating worse cognition).
