Validation of the russian version of the 4C Mortality Score and prediction of outcomes of severe COVID-19

The aim of the study is to validate the Russian version of the 4C Mortality Score scale and evaluate its accuracy in predicting the outcomes of severe COVID-19. Material and methods. The staff of the Center for Validation of International Scales and Questionnaires of the Research Center of Neurology received official permission from the authors to conduct a validation study of the 4C Mortality Score scale in Russia. In the course of the work, the linguistic and cultural ratification of the scale was carried out and its Russian-language version was prepared. Psychometric properties (reliability and validity) The Russian-language version was evaluated on a group of 78 patients (37 of whom were men, aged 34 to 88 years) with a confirmed diagnosis of COVID-19, hospitalized in the City Clinical Hospital No. 15 named after O.M. Filatov (Moscow) in the period from June to August 2021. Results. The linguocultural adaptation of the 4C Mortality Score scale was successfully carried out. High levels of reliability were obtained (Spearman correlation coefficient rho=0.91, p<0.0001;Cronbach's alpha alpha=0.73, p=0.0002;Cohen's kappa kappa=0.85, p<0.0001). It is shown that the 4C Mortality Score scores have a significant correlation with the COVID-GRAM scores (r=0.72, p=0.002) and NEWS2 (r=0.54, p=0.004). Conclusion. As a result of the validation study, the official Russian version of the 4C Mortality Score scale was developed. It is recommended for use by medical professionals of various specialties at all stages of providing medical care to patients with COVID-19.

Implementation of corticosteroids in treatment of COVID-19 in the ISARIC WHO Clinical Characterisation Protocol UK: prospective, cohort study

Background Dexamethasone was the first intervention proven to reduce mortality in patients with COVID-19 being treated in hospital. We aimed to evaluate the adoption of corticosteroids in the treatment of COVID-19 in the UK after the RECOVERY trial publication on June 16, 2020, and to identify discrepancies in care. Methods We did an audit of clinical implementation of corticosteroids in a prospective, observational, cohort study in 237 UK acute care hospitals between March 16, 2020, and April 14, 2021, restricted to patients aged 18 years or older with proven or high likelihood of COVID-19, who received supplementary oxygen. The primary outcome was administration of dexamethasone, prednisolone, hydrocortisone, or methylprednisolone. This study is registered with ISRCTN, ISRCTN66726260. Findings Between June 17, 2020, and April 14, 2021, 47 795 (75.2%) of 63 525 of patients on supplementary oxygen received corticosteroids, higher among patients requiring critical care than in those who received ward care (11 185 [86.6%] of 12 909 vs 36 415 [72.4%] of 50 278). Patients 50 years or older were significantly less likely to receive corticosteroids than those younger than 50 years (adjusted odds ratio 0.79 [95% CI 0.70-0.89], p=0.0001, for 70-79 years;0.52 [0.46-0.58], p<0.0001, for >80 years), independent of patient demographics and illness severity. 84 (54.2%) of 155 pregnant women received corticosteroids. Rates of corticosteroid administration increased from 27.5% in the week before June 16, 2020, to 75-80% in January, 2021. Interpretation Implementation of corticosteroids into clinical practice in the UK for patients with COVID-19 has been successful, but not universal. Patients older than 70 years, independent of illness severity, chronic neurological disease, and dementia, were less likely to receive corticosteroids than those who were younger, as were pregnant women. This could reflect appropriate clinical decision making, but the possibility of inequitable access to life-saving care should be considered. Copyright (C) 2022 The Author(s).
