Using Mixed-methods Approach to Explore the Long-term Effects of COVID-19

Overview

Researchers warned that up to 80% of the survivors may experience multiple and severe long-term symptoms, sometimes called Long Coronavirus Disease(Long COVID). These Long COVID can persist for longer than three months and cause profound distress and life interferences. The specific aims are to (1) integrate the state of science of Long COVID, (2) describe the changes of various symptoms and HRQOL(Health-related Quality of Life) after 3, 6, 9, and 12 months of COVID-19 diagnosis, (3) explore predicting factors of the existence and severity of Long COVID, and (4) explore how patient experienced COVID-19 symptoms. It is a mixed-methods research project with embedded design. Among the three research stages, a systematical review will be conducted first to address aim one. In stage two, a longitudinal cohort study will be carried out to recruit and follow up with individuals diagnosed with COVID-19 for a year. During the follow-up, the participants will need to report their symptoms via online questionnaire, phone or video interviews. Those who did experience COVID-19 symptoms will be invited to join stage three study. Stage three is a qualitative descriptive study addressing aim 4. Participants and recruitment. For stage two, the inclusion criteria are individuals who (1) are at least 20 years-old and (2) were diagnosed with COVID-19 within six months. Individuals who have cognitive impairment or other issues that prevents them from doing self-ratings of symptoms will be excluded. Expecting outcomes. It is expected that Long COVID will pose huge burden on survivors and their families. This project can provide a solid reference to foresee possible problems in this population and formulate strategies for early detection and management.

Background. When the COVID-19 pandemic sustains for more than a year, a growing number of COVID-19 survivors have returned to their community. However, researchers warned that up to 80% of the survivors may experience multiple and severe long-term symptoms, sometimes called Long COVID, even the subjects were asymptomatic or only had mild symptoms at diagnosis. These Long COVID can persist for longer than three months and cause profound distress and life interferences. Findings from studies and patient reports on social media suggest that various symptoms may be experienced, including fatigue, neurological symptoms, respiratory symptoms, and cardiovascular symptoms. With that being said, more areas, such as how Long COVID evolved after diagnosis, how investigators identify risk groups, and what are these survivors' needs, remain unclear. Aim. The overarching goal of this research project is to investigate the presentations and associating factors regarding Long COVID, and to explore survivor experience. The specific aims are to (1) integrate the state of science of Long COVID, (2) describe the changes of various symptoms and HRQOL after 3, 6, 9, and 12 months of COVID-19 diagnosis, (3) explore predicting factors of the existence and severity of Long COVID, and (4) explore how patient experienced COVID-19 symptoms. Design. It is a mixed-methods research project with embedded design. Among the three research stages, a systematical review will be conducted first to address aim one. In stage two, a longitudinal cohort study will be carried out to recruit and follow up with individuals diagnosed with COVID-19 for a year. During the follow-up, the participants will need to report their symptoms via online questionnaire, phone or video interviews (aim 2 and 3). Those who did experience COVID-19 symptoms will be invited to join stage three study. Stage three is a qualitative descriptive study addressing aim 4. Participants and recruitment. For stage two, the inclusion criteria are individuals who (1) are at least 20 years-old and (2) were diagnosed with COVID-19 within six months. Individuals who have cognitive impairment or other issues that prevents them from doing self-ratings of symptoms will be excluded. Potential participants will be identified through recruitment messages posting on social media and referrals from collaborating healthcare providers. Expecting outcomes. It is expected that Long COVID will pose huge burden on survivors and their families. This project can provide a solid reference to foresee possible problems in this population and formulate strategies for early detection and management. It is one of the few, if there is any, longitudinal study following up with COVID-19 survivors and including patients' perspectives.
