Validation of the COVID-19-12O scale for predicting readmissions/revisits in patients with SARS-CoV-2 pneumonia discharged from the emergency department Validación de la escala COVID-19-12O para predecir reingreso/revisita en pacientes con neumonía por SARS-CoV-2 dados de alta desde Urgencias

ABSTRACT

Objective The COVID-19-12O-SCORE has been validated to determine the risk of respiratory failure in patients hospitalized for COVID-19. Our study aims to assess whether the scale is effective in patients with SARS-CoV-2 pneumonia discharged from a hospital emergency department (HED) to predict readmission and revisit. Method Retrospective cohort of patients with SARS-CoV-2 pneumonia discharged consecutively from an HUS of a tertiary hospital, from January 7 to February 17, 2021, where we applied the COVID-19-12O -SCORE, with a cut-off point of 9 points to define the risk of admission or revisit. The primary outcome variable was revisit with or without hospital readmission after 30 days of discharge from HUS. Results We included 77 patients, with a median age of 59 years, 63.6% men and Charlson index of 2. 9.1% had an emergency room revisit and 15.3% had a deferred hospital admission. The relative risk (RR) for emergency journal was 0.46 (0.04–4.62, 95% CI, p = 0.452), and the RR for hospital readmission was 6.88 (1.20–39.49, 95% CI, p < 0.005). Conclusions The COVID-19-12O -SCORE is effective in determining the risk of hospital readmission in patients discharged from HED with SARS-CoV-2 pneumonia, but is not useful for assessing the risk of revisit.
