LOS ANGELES (CNS) – UCLA researchers are seeking participants for a study examining the impact of COVID-19 on survivors who continue battling health issues long after they were  infected and thought to have recovered.

The nationwide study will remotely track nearly 5,000 adults for up to two years, with the researchers looking closely at COVID-19 survivors’ reported and medically documented physical and mental function, including neurocognitive function and chronic fatigue.

“In this study, we are asking eligible individuals to share their health information so that researchers and doctors can better understand and improve the long-term clinical care for patients with ongoing health issues post COVID-19 infection,” said Dr. Joann Elmore, a professor of medicine in the division of general internal medicine and health services research at the David Geffen School of Medicine at UCLA.

The study, announced on Monday, Feb. 1, will be conducted in English and Spanish under the umbrella of INSPIRE — Innovative Support for Patients with SARS COV-2 Infections Registry — a Centers for Disease Control and Prevention-funded project led by Rush University Medical Center in Chicago. Other participating medical centers include UC San Francisco, the University of Washington, Yale New Haven Health, the University of Texas Houston, the University of Texas Southwestern and Thomas Jefferson University in Philadelphia.

Nationally, researchers hope to recruit 3,600 individuals who test positive for COVID-19 and another 1,200 individuals who test negative as a comparison. The study will gather information entirely online through short, ongoing surveys and will not require participants to see a doctor.

Screening and enrollment will be available through the UCLA study website, which will direct participants to a health data system portal that leverages individuals’ legal right to access their own health information and collects health data on their behalf. The study design will allow large-scale data gathering at the participant’s convenience while maintaining the highest degree of confidentiality and security, according to UCLA.

Individuals who are interested in participating in the study must meet the following criteria:

— be age 18 and older;

— have symptoms known to be associated with COVID-19;

— have been tested for COVID-19 within the previous 28 days, regardless of test result, and have not had a prior COVID-19 diagnosis; and

— have access to an internet connected device such as a smart phone, tablet, or computer to complete online surveys.

The researchers are also collaborating with patients who have had COVID-19 as part of the study’s Patient and Stakeholder Committee, to ensure that the research is informed by community experience and sensitive to their unique needs and concerns.

Coronavirus survivors such as Ruben Salazar, 43, who was infected in June, experienced a range of symptoms — headaches, fever, cough, loss of senses of smell and taste, body aches, difficulty breathing and nightmares.

Salazar spent 10 days at Ronald Reagan UCLA Medical Center — six of those in the intensive care unit, including four days in a medically induced coma and on a ventilator.

Salazar has since continued to experience fatigue and lightheadedness simply walking or going up a flight of stairs. His memory isn’t as sharp as it used to be and sometimes his mind wanders.

“It’s kind of like a brain fog,” he said.

Salazar hopes that research like the INSPIRE study will help other survivors, as well as medical providers, understand what patients are going through and perhaps lead to some physical and mental relief.

“I hope it gives answers to questions that people need answers to,’’ Salazar said. “If I have issues, I hope they have answers for it.”
