Factores de riesgo de rehospitalización en pacientes con COVID-19 leve tras el alta desde el servicio de urgencias / Risk factors for later hospitalization of patients discharged from an emergency department with non severe COVID-19 symptoms

RESUMEN

OBJETIVO: Describir la evolución clínica de pacientes con COVID-19 leve tras el alta de urgencias y analizar los posibles factores de riesgo para una posterior hospitalización. MÉTODO: Pacientes con COVID-19 leve dados de alta desde urgencias fueron prospectivamente incluidos. Los factores de riesgo de hospitalización fueron evaluados. RESULTADOS: Se incluyeron 74 pacientes y 17 (23%) requirieron hospitalización, de los cuales 3 (4%) fallecieron. La edad, la linfopenia, un mayor índice Charlson y un menor tiempo desde el inicio de los síntomas hasta la primera consulta a urgencias se asociaron a hospitalización, aunque en el análisis multivariado únicamente un tiempo desde el inicio de síntomas a la consulta a urgencias < 6 días se asoció a hospitalización (OR 4,62 IC 95% 1,08-19,7). CONCLUSIONES: Más del 20% de pacientes con COVID-19 leve dados de alta desde urgencias requiere hospitalización

ABSTRACT

OBJETIVES To describe the clinical course of patients discharged from the emergency department (ED) with non severe coronavirus disease 2019 (COVID-19) and explore possible risk factors for later hospitalization. METHODS: Patients with nonsevere COVID-19 who were discharged from the ED were included prospectively. We explored risk factors for hospitalization after discharge. RESULTS: Seventy-four patients were included; 17 (23%) were hospitalized after discharge. Three (4%) of the 17 patients died. Age, lymphopenia, a high Charlson Comorbidity Index, and a shorter delay between the onset of symptoms and the first visit to the ED were associated with hospitalization afterwards, although on multivariate analysis only time less than 6 days between symptom onset and the first ED visit was associated with later hospitalization (odds ratio, 4.62; 95% CI, 1.08-19.7). CONCLUSION: More than 20% of ED patients with nonsevere COVID-19 require hospitalization later
