Coronavirus Infection, Long-term Outcomes, Quality of Life
Conditions
Brief summary
The present study aims to assess the determinants of health-related quality of life and long-term outcomes among survivors of hospitalization for Covid-19 in Brazil. The investigators will conduct a multicenter prospective cohort study nested in randomized clinical trials (coalition Covid-19 Brazil initiative) originally designed to assess the effects of specific Covid-19 treatments. Adult survivors of hospitalization due to proven or suspected SARS-CoV-2 infection will be followed up for a period of one year by means of structured telephone interviews. The primary outcome is one-year health-related quality of life assessed by the EQ-5D-3L. Secondary outcomes include all-cause mortality, rehospitalizations, return to work or study, physical functional status assessed by the Lawton & Brody Instrumental Activities of Daily Living Scale, dyspnea assessed by the modified medical research council dyspnea scale, need of long-term ventilatory support, symptoms of anxiety and depression assessed by the Hospital Anxiety and Depression Scale, and symptoms of posttraumatic stress disorder assessed by the Impact of Event Scale-revised.
Interventions
Disease severity characterized by the highest six-level ordinal scale during the hospital stay, which consists of the following categories: a score of 1 indicated not hospitalized; 2, hospitalized and not receiving supplemental oxygen; 3, hospitalized and receiving supplemental oxygen; 4, hospitalized and receiving oxygen supplementation administered by a high-flow nasal cannula or noninvasive ventilation; 5, hospitalized and receiving mechanical ventilation; and 6, death

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| One-year utility score of health-related quality of life | The 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
| Measure | Time frame | Description |
|---|---|---|
| Incidence of rehospitalizations | The outcome will be assessed 3, 6, 9 and 12 months after enrollment. | Incidence of all-cause rehospitalizations. |
| Percentage of return to work or study | The outcome will be assessed 3, 6, 9 and 12 months after enrollment. | Percentage of return to work or study among patients that were working or studying at the moment of hospitalization. |
| Score of Instrumental Activities of Daily Living | The outcome will be assessed 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). |
| Score of dyspnea | The outcome will be assessed 3, 6, 9, and 12 months after enrollment. | The outcome will be assessed using the modified medical research council dyspnea scale. Scores ranges from 0 to 4, with higher scores indicating worse symptoms. |
| Incidence of all-cause mortality | The outcome will be assessed 3, 6, 9 and 12 months after enrollment. | Incidence of all-cause mortality. |
| Symptoms of anxiety and depression | The outcome will be assessed 3, 6, 9 and 12 months after enrollment. | The outcome will be assessed using the Hospital Anxiety and Depression Scale (anxiety and depression scores range from 0 to 21, with higher scores indicating worse symptoms). |
| Symptoms of posttraumatic stress disorder | The outcome will be assessed 3, 6, 9 and 12 months after enrollment. | The outcome will be assessed using the Impact Event Scale-Revised (the score ranges from 0 to 88, with higher scores indicating worse symptoms). |
| Utility score of health-related quality of life at 3, 6, and 9 months | The outcome will be assessed 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). |
| Score of self-rated health | The outcome will be assessed 3, 6, 9, and 12 months after enrollment. | The outcome will be assessed using the visual analogue scale of the Brazilian version of the Euroqol-5D-3L questionnaire (EQ-VAS; score range from o to 100, with higher scores indicating better self-rated health). |
| Percentage of long-term ventilatory support need | The outcome will be assessed 3, 6, 9 and 12 months after enrollment. | Percentage of patients requiring oxygen therapy, non-invasive ventilation, or mechanical ventilation. |
