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

OBJECTIVES: To describe the clinical course of patients discharged from the emergency department (ED) with nonsevere coronavirus disease 2019 (COVID-19) and explore possible risk factors for later hospitalization. MATERIAL AND 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.

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. METODO: 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.

Association between environmental factors and hospitalisations for bronchiectasis in Badalona, Barcelona, Spain (2007-2015). / Asociación entre factores ambientales e ingresos por bronquiectasias en Badalona, Barcelona (2007-2015).

INTRODUCTION: The relationship between environmental factors and the exacerbation of respiratory diseases has been widely studied. However, there are no studies examining the relationship between these factors and bronchiectasis exacerbations. Our objective was to analyse the association between various environmental factors and hospitalisation for bronchiectasis. MATERIAL AND METHODS: This was a retrospective observational study conducted at two hospitals in Badalona (Barcelona). The number of hospital admissions for exacerbation of bronchiectasis between 2007 and 2015 was obtained. Through multiple regression we analysed the relationship between the number of exacerbations and mean monthly values of temperature, SO2, NO, NO2, O3 and CO. RESULTS: Temperature, SO2, NO, NO2, O3 and CO were significantly associated with an increase in admissions due to exacerbation of bronchiectasis. By controlling the effect of temperature on the pollution variables, only SO2 maintained statistical significance (P=.008). CONCLUSION: We have detected an increase in hospital admissions for exacerbation of bronchiectasis with increases in the atmospheric concentration of SO2 and the decrease in temperature. Prospective studies with different geographical locations to confirm these results are needed.
