About half of adults treated at hospitals for COVID-19 have experienced lingering symptoms, financial difficulties, or physical limitations months after being discharged, according to a National Institutes of Health-supported study published in JAMA Network Open.
After six months, more than 7 in 10 adults surveyed in the study experienced cardiopulmonary problems, such as coughing, rapid or irregular heartbeat, and breathlessness, while about half had fatigue or physical limitations -- all symptoms associated with long COVID. Additionally, more than half of the adults said they faced financial challenges.
The findings came from the PETAL Network's Biology and Longitudinal Epidemiology: COVID-19 Observational (BLUE CORAL) study, which is supported by the National Heart, Lung, and Blood Institute (NHLBI), part of NIH.
"My clinic patients often want to know how soon they'll get back to their usual health," said Andrew J. Admon, M.D., M.P.H., the study's first author, a pulmonologist at LTC Charles S. Kettles VA Medical Center, and an assistant professor in the departments of internal medicine and epidemiology at the University of Michigan, Ann Arbor. "Based on these data, it seems that many people hospitalized for COVID-19 should expect symptoms to last for up to six months or even longer."
To conduct the analysis, researchers assessed data from the medical records and follow-up surveys of 825 adults who received treatment for COVID at one of 44 medical centers in the United States between August 2020 and July 2021. Patients were surveyed one, three, and six months after leaving the hospital for general or intensive care treatment.
The researchers found that six months after being hospitalized:
"These findings will inform programs designed to help adults recover from severe cases of COVID and guide how physicians should check in with patients in the year following hospitalization," said James P. Kiley, Ph.D., the director of NHLBI's Division of Lung Diseases. "They may also help shape future clinical research studies."
For a bigger picture, other studies, such as the Household Pulse Survey, have suggested that half of U.S. adults have reported having COVID. International data suggest that about 1 in 13 adults, 6-7%, who have had symptomatic COVID infections still experienced symptoms months later. Based on research published in JAMA, symptoms lasted for about four months for those who recovered outside of the hospital compared to nine months for those who received hospital care.
