In the nine patients 81 years or older, the PPV was 44% (95%CI: 14–79) compared with 80% (95%CI: 28–99) in the five patients less than 18 years of age. Overall, the diagnosis of long-COVID was confirmed in 249/266 yielding a PPV of 94% (95%CI: 90–96). One or more constitutional symptoms were present in 211/266 (79%) patients, with fatigue 180/266 (68%) as the most common. The patients’ symptoms were divided into constitutional and organ specific symptoms. In addition, all patients admitted with acute COVID-19 infection requiring oxygen treatment were invited to a follow-up examination at Aalborg University Hospital.Ībbreviations: COVID-19, coronavirus disease 2019 ENT, ear-nose-throat. 14, 15 Patients eligible for consultation at the hospital outpatient clinic were required to have had symptoms for >6 weeks and a previous SARS-CoV-2 infection documented by a positive polymerase chain reaction (PCR) test on a respiratory sample or a positive serum antibody test. The catchment population was 590,439 (January 1, 2021) and 21,727 had tested positive for SARS-CoV-2 in the North Denmark Region during the study period. 10 In the North Denmark Region, an outpatient clinic for patients with long-COVID was established on Januat Aalborg University Hospital ( Figure 1).

Another study considered hospital diagnosis codes and medication prescriptions as proxies for long-COVID among SARS-CoV-2 positive compared with negative individuals and observed an increased risk of dyspnea and prescription of bronchodilating agents following infection. 4–7 In addition, the generalizability of hospitalized COVID-19 patients from countries with overwhelmed health-care systems during the very onset of the pandemic may be limited.

4–6 However, many of these reports are single-center studies or rely on voluntary reports of symptoms using, eg a smartphone application, which may introduce selection and information bias. 2, 3Įarly studies found that 10–13% of all SARS-CoV-2 positive individuals reported persistent symptoms for several months, 2 which increased to 72–87% when examining only patients hospitalized with coronavirus disease 2019 (COVID-19).

Although there is no universally accepted definition, this is often termed “long coronavirus disease” (long-COVID) and it may have a significant impact on social functioning, work capacity, and quality of life of patients. 1 In addition, the infection may cause prolonged or new-onset symptoms following infection.
