Post COVID-19 Syndrome (Long Haul Syndrome): Description of a Multidisciplinary Clinic at the Mayo Clinic and Characteristics of the Initial Patient Cohort

Abstract Objective To describe characteristics of a series of patients reporting prolonged symptoms after an infection with COVID-19. Methods This study describes the multidisciplinary COVID-19 Activity Rehabilitation Program (CARP), established at Mayo Clinic to evaluate and treat post-COVID-19 syndrome (PCS) patients, and reports the clinical characteristics of the first 100 patients receiving evaluation and management during the timeframe of June 1, 2020 and December 31, 2020. Results The cohort consisted of 100 patients (mean age 45 years, 68% women, BMI 30.2, presenting a mean of 93 days after infection). Common pre-existing conditions were respiratory (23%) and mental health, including depression and/or anxiety (34%.) The majority (75%) had not been hospitalized for COVID-19. Common presenting symptoms ware fatigue (80%), respiratory complaints (59%), and neurologic complaints (59%) followed by subjective cognitive impairment, sleep disturbance, and mental health symptoms. More than one-third of the patients (34%) reported difficulties with performing basic activities of daily living. Only 1 in 3 patients had returned to unrestricted work duty at the time of the analysis. For most patients, laboratory and imaging studies were normal or non-diagnostic despite debilitating symptoms. Most patients required physical therapy, occupational therapy, or brain rehabilitation. Face-to-face and virtual care delivery modalities were feasible. Conclusion Many of the patients did not experience COVID-19-related symptoms that were severe enough to require hospitalization, were younger than 65 years of age, more likely to be female, and most had no pre-existing comorbidities prior to SARS-CoV-2 infection. Symptoms including mood disorders, fatigue, and perceived cognitive impairment resulted in severe negative impacts on resumption of functional and occupational activities in patients experiencing prolonged effects.
