[Revisit after discharge from the emergency department in a cohort of patients with COVID-19 pneumonia and analysis based on the healthcare resource used for follow-up. RESALSEVID study]. / Análisis de la evolucion tras el alta de urgencias en pacientes con neumonía por COVID-19 en función del recurso sanitario utilizado para el seguimiento: estudio RESALSEVID.

INTRODUCTION: COVID-19 pneumonia is a manifestation of SARS-CoV-2 infection and in most cases involves hospital admission. There are recommendations according to which these patients can be discharged without hospital admission, but there is no evidence regarding the revisit and the most appropriate type of follow-up. The objective of the RESALSEVID study was to investigate the variables associated with the 30-day revisit (Rev30d) in a group of patients discharged directly from 4 emergency departments (ED) with COVID-19 pneumonia, and analyze whether there were differences based on 4 different tracking devices. METHOD: Analysis of a prospective cohort of patients discharged directly from the ED with COVID-19 pneumonia in 4 hospital with different models of follow-up at discharge (primary care, hospitalization at home [HaH] phone and in person, HaH phone, hospital phone). RESULTS: Five hundred twenty patients were included, with a mean age of 50.1 years and 51% men. Rev30d was 18.3% and was related only to immunosuppression, odds ratio 4.49 (95% confidence interval 1.10-18.24); p=0.022. There was no difference in Rev30d based on the follow-up model used at discharge from the ED. CONCLUSIONS: There are some recommendations that allow the safe discharge of patients with COVID-19 pneumonia, with no differences in Rev30d depending on the type of follow-up.

Análisis de la evolucion tras el alta de urgencias en pacientes con neumonía por COVID19 en función del recurso sanitario utilizado para el seguimiento: Estudio RESALSEVID Revisit after discharge from the emergency department in a cohort of patients with COVID19 pneumonia and analysis based on the healthcare resource used for follow-up. RESALSEVID study

Introducción: la neumonía COVID19 es una manifestación de la infección por SARS-CoV-2 y en la mayoría de casos supone ingreso hospitalario. Existen recomendaciones según las cuales se puede dar de alta a estos pacientes sin precisar ingreso hospitalario, pero no hay evidencia en relación a la revisita y el tipo de seguimiento más adecuado. El objetivo del estudio RESALSEVID fue investigar las variables asociadas a la revisita a los 30 días (Rev30d) en un grupo de pacientes dados de alta directamente en 4 servicios de urgencias hospitalarios (SUH) con neumonía COVID19, y analizar si existieron diferencias en función de 4 dispositivos de seguimiento diferentes. Método: análisis de una cohorte prospectiva de pacientes dados de alta directamente desde urgencias con neumonía COVID19 en 4 SUH con diferentes modelos de seguimiento al alta (atención primaria, hospitalización a domicilio [HaD] telefónico y presencial, HaD telefónico, telefónico hospitalario). Resultados: se incluyeron 520 pacientes, con una media de edad de 50,1 años y 51% varones. La Rev30d fue del 18,3% y se relacionó únicamente con la inmunosupresión, odds ratio 4,49 (intervalo de confianza del 95% 1,10 – 18,24);p=0,022. No hubo ninguna diferencia en la Rev30d en función del modelo de seguimiento utilizado al alta de urgencias. Conclusiones: existen una serie de recomendaciones que permiten dar de alta de manera segura a pacientes con neumonía COVID19, no existiendo diferencias en la Rev30d en función del tipo de seguimiento.

Impact of COVID-19 on Hospital Admissions and Healthcare Quality Indicators in Non-COVID Patients: A Retrospective Study of the First COVID-19 Year in a University Hospital in Spain.

Few studies have assessed the impact of the COVID-19 pandemic on non-COVID diseases and healthcare quality. We aimed to evaluate changes in rates of hospitalisations, complications, in-hospital mortality, and readmissions among patients with non-COVID diseases during a one-year period after the pandemic onset. From March 2018 to February 2021 a retrospective observational study of hospital admissions in a university hospital in Spain was conducted. Non-COVID hospitalisations admitted through the emergency department were compared between the pre-COVID period (n = 28,622) and the COVID period (n = 11,904). We assessed rate ratios (RaR), comparing the weekly number of admissions and risk ratios (RR) to examine rates of complications, in-hospital mortality, readmissions, and severity. Statistical significance was set at p < 0.05. The weekly admission rate dropped by 20.8% during the complete lockdown. We observed significant reductions in admissions related to diseases of the respiratory system and circulatory system. Admissions for endocrine and metabolic diseases increased. The complication rates increased (RR = 1.21, 95% CI: 1.05;1.4), while in-hospital mortality rates held steady during the COVID period (RR = 1.09, 95% CI: 0.98;1.2). Hospital efforts to maintain quality and safety standards despite disruptions translated into a moderate increase in complications but not in in-hospital mortality. Reduced hospitalisations for conditions requiring timely treatment may have significant public health consequences.
