Abstract:
Background: Some patients do not fully recover after COVID-19 and have symptoms occurring 3 months after acute illness, lasting for >2 months, defined as post COVID-19. Fatigue seems most present in post COVID-19 and part of the patients might develop symptoms similar to chronic fatigue syndrome.
Aim: To determine the occurrence of fatigue and other symptoms in post COVID-19 patients.
Methods: In the prospective P4O2 COVID-19 cohort, post COVID-19 patients aged 40-65 years were recruited from outpatient post-COVID clinics in 5 Dutch hospitals between May 2021-September 2022. At 3-6 months post-COVID, patients completed the Fatigue Severity Scale (FSS). If the FSS score was ≥4 (the cut-off for severe fatigue), patients also completed the DePaul Symptom Questionnaire version 2 (DSQ-2). The FSS ranges from 1-7 and a higher score means more fatigued. The DSQ-2 rates frequency and severity of 79 symptoms on a 5-point Likert scale. Binary thresholds (if scored ≥2 on both severity and frequency, the threshold is met and the symptom is present) were calculated.
Results: The mean age of the 78 included patients was 53.9±6.2 and 51.7% were male. Median (IQR) FSS score was 5.6 (4.2-6.3) and 66 patients (84.6%) had a score ≥4. According to the DSQ-2 (n=61), patients reported a median (IQR) of 16 (8-23) symptoms. The majority of the patients experienced fatigue (85%). Furthermore, post-exertional malaise (PEM) (40%), sleep-related problems (37%), pain (21%) and neurocognitive problems (23%) were frequently reported.
Conclusion: The occurrence of severe fatigue 3-6 months after COVID-19 was 84.6% in our cohort. Patients with severe fatigue also frequently reported PEM, sleep related problems, pain and neurocognitive problems.
