What researchers measure

Primary outcomes

  1. One-year utility score of health related quality of life

    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).

    Time frame: The outcome will be assessed 12 months after enrollment.

Secondary outcomes

  1. Utility score of health related quality of life at 3, 6, and 9 months

    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).

    Time frame: The outcome will be assessed at 3, 6, and 9 months after enrollment.

  2. Incidence of all-cause mortality

    Incidence of all-cause mortality

    Time frame: The outcome will be assessed at 1, 3, 6, 9, and 12 months after enrollment.

  3. Incidence of major cardiovascular events

    Incidence of major cardiovascular events (composite endpoint of non-fatal stroke, non-fatal acute myocardial infarction, or cardiovascular death)

    Time frame: The outcome will be assessed at 3, 6, 9, and 12 months after enrollment.

  4. Incidence of hospitalizations

    Incidence of all-cause hospitalizations

    Time frame: The outcome will be assessed at 1, 3, 6, 9, and 12 months after enrollment.

  5. Prevalence of prolonged COVID-19 symptoms

    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)

    Time frame: The outcome will be assessed at 1, 3, 6, 9, and 12 months after enrollment.

  6. Prevalence of cognitive dysfunction

    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).

    Time frame: The outcome will be assessed at 3, 6, 9, and 12 months after enrollment.

  7. Prevalence of anxiety and depression symptoms

    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).

    Time frame: The outcome will be assessed at 3, 6, 9, and 12 months after enrollment.

  8. Prevalence of posttraumatic stress disorder symptoms

    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).

    Time frame: The outcome will be assessed at 3, 6, 9, and 12 months after enrollment.

  9. Physical functional status

    Physical functional status as assessed by the modified Barthel index (score ranges from 0 to 100; higher scores indicate less functional dependence).

    Time frame: The outcome will be assessed at 3, 6, 9, and 12 months after enrollment.

  10. Instrumental Activities of Daily Living

    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).

    Time frame: The outcome will be assessed at 3, 6, 9, and 12 months after enrollment.

  11. Incidence of return to work or study

    Incidence of return to work or study among patients that were working or studying at the moment of COVID-19 diagnosis.

    Time frame: The outcome will be assessed at 3, 6, 9, and 12 months after enrollment.

  12. Incidence of new symptomatic COVID-19 infection

    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.
