The study published in The Lancet Digital Health explores the trajectories of COVID-19 among more than 57 million adults in England, using data from Electronic Health Records (EHR).<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

The study authors sought to make estimates about the onset, progression, and trajectories of COVID through the various efforts that were and continue to be used to mitigate the pandemic. To identify these trajectories, the authors defined and validated ten COVID-19 phenotypes through ECE collected nationally by the National Health Service (NHS).<\/p>

The authors used eight NHS-linked data sets of people residing in England on 23 January 2020. Other relevant data such as COVID-19 testing, vaccination, primary care, secondary care and death records were collected up to 30 January. November 2021.<\/p>

The ten phenotypes of COVID-19 reflect relevant stages in the clinical aspect, and on the severity of the disease, these are divided into five categories: Positive COVID tests, primary care diagnosis, hospital admission, ventilation modality that included four phenotypes and death that included three.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

The study explains that the phenotypes presented have already been used to carry out other analyzes such as implications of relevant public health policies, evaluation of the association of the vaccines against COVID-19 ChAdOx1 and BNT162b2 with venous, arterial and thrombocytopenic events, evaluation of the use of antithrombotic drugs on COVID-19 outcomes and the study of the incidence of vascular diseases after COVID-19 infection.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

Of the 57 million 32 thousand 174 individuals, 13 million 990 thousand 432 events related to COVID-19 were identified in 7 million 244 thousand 925 patients. This represented an infection rate of 12.7% during the study period. Of this percentage, 6.4% were admitted to hospital and 2.2% died.<\/p>

Similarly, they collected data such as the number of patients in intensive care (10.6%), or the number of patients who received invasive (5.6%) and non-invasive (15%) ventilation.<\/p>

Furthermore, patient trajectories by demographics were key to identifying patterns that included fewer days between a positive test and primary care diagnosis. This suggests that some groups could be accessing medical care in the course of the disease. In other words, the analysis also worked to identify socioeconomic inequalities in health and access to public health services.<\/p>

"The networks presented provide a succinct and interpretable view, at the national level, of how and when COVID-19 patients interact with the health system and the individual disease trajectories they follow," the authors explain.<\/p>

El estudio publicado en The Lancet Digital Health explora las trayectorias de COVID-19 entre m\u00e1s de 57 millones de adultos en Inglaterra, utilizando datos de Expedientes Cl\u00ednicos Electr\u00f3nicos (ECE). Los autores del estudio buscaron realizar estimaciones sobre el inicio, la progresi\u00f3n y las trayectorias de COVID a trav\u00e9s de los diversos esfuerzos que se utilizaron y se contin\u00faan utilizando para mitigar la pandemia. Para la identificaci\u00f3n de esas trayectorias los autores definieron y validaron diez fenotipos de COVID-19 a trav\u00e9s de ECE recopilados a nivel nacional por el Servicio Nacional de Salud (NHS). Los autores utilizaron ocho conjuntos de datos vinculados al NHS de personas con residencia en Inglaterra el 23 de enero de 2020. Otros datos relevantes como pruebas COVID-19, vacunaci\u00f3n, registros de atenci\u00f3n primaria, secundaria y registros de defunci\u00f3n se recopilaron hasta el 30 de noviembre de 2021. Los diez fenotipos de COVID-19 reflejan etapas relevantes en el aspecto cl\u00ednico, y sobre la gravedad de la enfermedad, estas est\u00e1n divididas en cinco categor\u00edas: Pruebas COVID positivas, diagn\u00f3stico de atenci\u00f3n primaria, ingreso hospitalario, modalidad de ventilaci\u00f3n que incluy\u00f3 cuatro fenotipos y fallecimiento que incluy\u00f3 tres. El estudio explica que los fenotipos presentados ya han sido utilizados para realizar otros an\u00e1lisis como implicaciones de pol\u00edticas de salud p\u00fablica relevantes, evaluaci\u00f3n de asociaci\u00f3n de las vacunas contra el COVID-19 ChAdOx1 y BNT162b2 con eventos venosos, arteriales y trombocitop\u00e9nicos, evaluaci\u00f3n del uso de medicamentos antitromb\u00f3ticos en los resultados de COVID-19 y el estudio de la incidencia de enfermedades vasculares despu\u00e9s de la infecci\u00f3n por COVID-19. De los 57 millones 32 mil 174 individuos, fueron identificados 13 millones 990 mil 432 eventos relacionados con COVID-19 en 7 millones 244 mil 925 pacientes. Esto represent\u00f3 una tasa de infecci\u00f3n del 12,7% durante el periodo que abarc\u00f3 el estudio. De este porcentaje, el 6,4% ingresaron al hospital y el 2,2% muri\u00f3. De igual forma recopilaron datos como la cantidad de pacientes en cuidados intensivos (10,6%), o la cantidad de pacientes que recibieron ventilaci\u00f3n invasiva (5,6%) y no invasiva (15%). Por otra parte, las trayectorias de los pacientes por demograf\u00eda fueron clave para identificar patrones que incluyeron menos d\u00edas entre una prueba positiva y el diagn\u00f3stico de atenci\u00f3n primaria. Esto sugiere que algunos grupos podr\u00edan estar accediendo a atenci\u00f3n m\u00e9dica en el curso de la enfermedad. Es decir, el an\u00e1lisis tambi\u00e9n funcion\u00f3 para identificar desigualdades socioecon\u00f3micas en salud y acceso los servicios p\u00fablicos de salud. \u201cLas redes presentadas brindan una visi\u00f3n sucinta e interpretable, a nivel nacional, de c\u00f3mo y cu\u00e1ndo los pacientes con COVID-19 interact\u00faan con el sistema de salud y las trayectorias de enfermedad individuales que siguen\u201d, explican los autores.
