ABSTRACT
Objetivo: Describir la incidencia y mortalidad de COVID-19, durante la primera ola, en la población de personas mayores de Barcelona, según sus niveles previos de fragilidad. Diseño: Estudio de cohortes retrospectivo. Emplazamiento y participantes: Población de 65 o más años asignada a los centros de Atención Primaria de Barcelona del Institut Català de la Salut, seguidos entre marzo y junio de 2020. Mediciones principales: Fragilidad calculada al inicio a partir de la historia clínica informatizada. Resultados durante el seguimiento: diagnóstico de COVID-19, posible o confirmado con PCR y mortalidad por todas las causas. Resultados: Se analizaron 251788 mayores de 64 años. Un 61,3% tenían algún nivel de fragilidad, 27,8% moderada o grave. La incidencia de COVID-19 fue de 3,13 casos por 100 habitantes (N = 7883) y la mortalidad por COVID-19 fue del 21,5% (N =1 691). Tanto la incidencia como la mortalidad por COVID-19 fueron superiores a mayor edad, en hombres, a mayor privación y a mayor nivel de fragilidad. Los individuos con fragilidad leve, moderada y grave tuvieron un hazard ratio ajustado de enfermedad por COVID-19 de 1,47, 2,08 y 3,50 respectivamente. Entre los sujetos con COVID-19, aquéllos con fragilidad leve, moderada y grave tuvieron un hazard ratio ajustado de mortalidad por COVID-19 de 1,44, 1,69 y 2,47 respectivamente. Conclusiones: Consideramos necesario el abordaje de la fragilidad también en situación de pandemia, dado que es una condición tratable y a su vez factor de riesgo de COVID-19 más grave, donde el papel de la Atención Primaria es primordial, por su accesibilidad y longitudinalidad.(AU)
Objetive: To describe the incidence and mortality of the first wave of COVID-19 in the elderly population of Barcelona, according to their previous levels of frailty. Design: Retrospective cohort study. Setting and participants: Population aged 65 or over assigned to the Barcelona Primary Care centres of the Institut Català de la Salut, followed between March and June 2020. Main measurements: Frailty was calculated at baseline from the computerised medical records. Results during follow-up: diagnosis of COVID-19, possible or confirmed with PCR and all-cause mortality. Results: 251788 patients over 64 years of age were analysed, 61.3% had some level of frailty, 27.8% moderate or severe. The incidence of COVID-19 was 3.13 cases per 100 inhabitants (N=7883) and the mortality from COVID-19 was 21.5% (N=1691). Both the incidence and mortality from COVID-19 were higher at older age, in men, at greater deprivation and at a higher level of frailty. Individuals with mild, moderate, and severe frailty had an adjusted Hazard Ratio (HR) for COVID-19 disease of 1.47, 2.08, and 3.50, respectively. Among subjects with COVID-19, those with mild, moderate, and severe frailty had an adjusted HR for COVID-19 mortality of 1.44, 1.69, and 2.47, respectively. Conclusions: We consider it necessary to address frailty also in a pandemic situation, since it is a treatable condition and in turn a more serious risk factor for COVID-19, where the role of primary care is essential, due to its accessibility and longitudinal character.(AU)
