Purpose of the study. Estimate the functional status of patients using the PCFS (Post-COVID-19 Functional Status) scale.
Material and research methods. There were 281 patients under observation, with the presence of clinical manifestations of post covid-19 syndrome. As a control group (CG), 20 patients who had undergone COVID-19 and whose disease ended in full recovery were examined. The assessment of the functional status of patients after suffering COVID-19 was carried out using the PCFS method - Post-COVID-19 Functional Status (https://osf.io/qgpdv/).
Research results. In the main group of patients, the average score of the questionnaire was 13.34 ± 0.83 points. Patients who have identified a violation of their functional status at 1 point were 13 patients (4.63%), at 2 points - 90 people (32.03%), at 3 points - 117 people (41.64%), at 4 points - 61 people. (21.71%). In the control group, the patients assessed violations of their functional status at 0 points. The number of patients with extremely severe, severe and moderately severe COVID-19 was significantly higher in the main group than in the control group (30.61% versus 20%, 35.94% versus 30%, 33.45 versus 30%, respectively) In the main group of patients, the average number of background diseases was significantly higher than in the control group (p <0.05).
Conclusion. Patients with post covid syndrome have a higher score on the functional status scale (PCFS). Among the patients who scored 3 and 4 points on the PCFS test (significant limitation of daily activity due to symptoms associated with the previous infection and the need for help in self-care), there were more patients with a severe course of COVID-19 and background cardiovascular pathology and obesity.
