Abstract
BackgroundRecent studies showed that a significant percentage of people who recovered from coronavirus disease 2019 (COVID-19) had lingering symptoms. Among patients diagnosed with COVID-19 infection, studies showed persistent symptoms both in patients hospitalized and in outpatient settings. In the studies done in the outpatient setting involving mild to moderate COVID-19 patients, there were significant variations regarding the exact percentage of people with lingering symptoms. Also, in the outpatient setting, not many studies were done on COVID-19 patients that assessed risk factors for having lingering symptoms. Given that a large percentage of people infected with COVID-19 infection do not get hospitalized, it is imperative that this lacuna be filled. We believe knowing the details of long-term symptoms of COVID-19 infection both from prevalence and predictors point of view, could allow the physicians, healthcare system and community to better prepare for managing and following these patients.Materials and methodsOur study period was within 12 months after the first documented case of COVID-19 occurred in the State of Alabama. Our study population included patients who were diagnosed with a documented case of COVID-19 in this time period and were under the care of a single primary care provider at an ambulatory clinic. Among 80 patients who had documented COVID-19, three left the practice, two declined to participate in the study and three were deceased (two due to COVID-19 and one for other reasons). Therefore, the study population constituted 72 patients. A questionnaire was mailed to all 72 patients to see how many of them had symptoms three months and beyond of having COVID-19 infection. A chart review was conducted for the study participants to assess for “Comorbid conditions”, health conditions that were considered conclusively high risk for acute COVID-19 infection by US Center for Disease Control and Prevention (CDC).ResultsFifty-three patients responded to the questionnaire; 27 patients (50.9%) reported lingering symptoms beyond three months of diagnosis with COVID-19 infection. The three most common symptoms reported were fatigue (56%), brain fog (48%), and shortness of breath (41%). The results also showed that women are more likely than men to have lingering symptoms. “Elderly” (≥65 years) patients were as likely as 18-64 years old patients to have lingering symptoms and the presence of one or more of the “Comorbid conditions” does not have any bearing on the occurrence of lingering symptoms.ConclusionFuture studies should be done in a larger population to assess the findings that our study showed regarding “elderly” age and the presence of one or more “comorbid conditions” being independent variables of the occurrence of prolonged COVID-19 symptoms.We recommend studies be done assessing the prevalence and predictors for the long-term effects of the COVID-19 infection. This knowledge could help in preventing those long-term symptoms from occurring in the first place and also in preparing the patient, the physician and the community in managing the outcomes effectively.
