Cohort Study for the Assessment of Long-term Impact of COVID-19 Among Moderate and Severe COVID-19 Patients in Brazil

November 3, 2023 updated by: Hospital Moinhos de Vento
The present prospective cohort study aims to assess factors associated with of one-year health-related quality of life and physical, cognitive and mental health outcomes among adult survivors of hospitalization for COVID-19. Adult patients requiring hospitalization due to COVID-19 disease will be followed through structured and centralized telephone interviews performed at 3, 6, 9 and 12 months after enrollment.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures
